Installation
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before mounting the product:
DDo not install any system component where service conditions could exceed the limits given in this manual or the limits on the appropriate nameplates. Use pressure-relieving devices as required by government or accepted industry codes and good engineering practices.
DAlways wear protective gloves, clothing, and eyewear when performing any installation operations.
DDo not remove the actuator from the valve while the valve is still pressurized.
DDisconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.
DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve.
DVent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not applying force to the valve stem; this will allow for the safe removal of the stem connector.
DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
DThe instrument is capable of supplying full supply pressure to connected equipment. To avoid personal injury and equipment damage, caused by sudden release of process pressure or bursting of parts, make sure the supply pressure never exceeds the maximum safe working pressure of any connected equipment.
DSevere personal injury or property damage may occur from an uncontrolled process if the instrument air supply is not clean, dry and oil-free, or noncorrosive gas. While use and regular maintenance of a filter that removes particles larger than 40 microns will suffice in most applications, check with an Emerson field office and Industry Instrument air quality standards for use with corrosive gas or if you are unsure about the proper amount or method of air filtration or filter maintenance.
DFor corrosive media, make sure the tubing and instrument components that contact the corrosive media are of suitable corrosion-resistant material. The use of unsuitable materials might result in personal injury or property damage due to the uncontrolled release of the corrosive media.
DIf natural gas or other flammable or hazardous gas is to be used as the supply pressure medium and preventive measures are not taken, personal injury and property damage could result from fire or explosion of accumulated gas or from contact with hazardous gas. Preventive measures may include, but are not limited to: Remote venting of the unit, re-evaluating the hazardous area classification, ensuring adequate ventilation, and the removal of any ignition sources.
DTo avoid personal injury or property damage resulting from the sudden release of process pressure, use a high-pressure regulator system when operating the controller or transmitter from a high-pressure source.
The instrument or instrument/actuator assembly does not form a gas-tight seal, and when the assembly is in an enclosed area, a remote vent line, adequate ventilation, and necessary safety measures should be used. Vent line piping should comply with local and regional codes and should be as short as possible with adequate inside diameter and few bends to reduce case pressure buildup. However, a remote vent pipe alone cannot be relied upon to remove all hazardous gas, and leaks may still occur.
DPersonal injury or property damage can result from the discharge of static electricity when flammable or hazardous gases are present. Connect a 14 AWG (2.08 mm2) ground strap between the instrument and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements.
DPersonal injury or property damage caused by fire or explosion may occur if electrical connections are attempted in an area that contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of covers before proceeding.
DPersonal injury or property damage, caused by fire or explosion from the leakage of flammable or hazardous gas, can result if a suitable conduit seal is not installed. For explosion-proof applications, install the seal no more than 457 mm (18 inches) from the instrument when required by the nameplate. For ATEX applications use the proper cable gland certified to the required category. Equipment must be installed per local and national electric codes.
DCheck with your process or safety engineer for any additional measures that must be taken to protect against process media.

Maintenance
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations on an actuator-mounted instrument or accessory:
DAlways wear protective gloves, clothing, and eyewear.
DProvide some temporary measure of control to the process before taking the instrument out of service.
DProvide a means of containing the process fluid before removing any measurement devices from the process.
DDisconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.
DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve.
DVent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not applying force to the valve stem; this will allow for the safe removal of the stem connector.
DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
DCheck with your process or safety engineer for any additional measures that must be taken to protect against process media.
When using natural gas as the supply medium, or for explosion proof applications, the following warnings also apply:
DRemove electrical power before removing any housing cover or cap. Personal injury or property damage from fire or explosion may result if power is not disconnected before removing the cover or cap.
DRemove electrical power before disconnecting any of the pneumatic connections.
DWhen disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of the following: ensuring adequate ventilation and the removal of any ignition sources.
DEnsure that all housing caps and covers are correctly installed before putting this unit back into service. Failure to do so could result in personal injury or property damage from fire or explosion.

Instruments Mounted on Tank or Cage
WARNING
For instruments mounted on a tank or displacer cage, release trapped pressure from the tank and lower the liquid level to a point below the connection. This precaution is necessary to avoid personal injury from contact with the process fluid.

Instruments With a Hollow Displacer or Float
WARNING
For instruments with a hollow liquid level displacer, the displacer might retain process fluid or pressure. Personal injury and property might result from sudden release of this pressure or fluid. Contact with hazardous fluid, fire, or explosion can be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not be readily apparent when disassembling the sensor or removing the displacer. A displacer that has been penetrated by process pressure or fluid might contain: Dpressure as a result of being in a pressurized vessel Dliquid that becomes pressurized due to a change in temperature Dliquid that is flammable, hazardous or corrosive. Handle the displacer with care. Consider the characteristics of the specific process liquid in use. Before removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.

DLC3010 digital level controllers are communicating, microprocessor-based level, interface, or density sensing instruments. In addition to the normal function of providing a 4-20 milliampere current signal, DLC3010 digital level controllers, using the HARTR communications protocol, give easy access to information critical to process operation. You can gain information from the process, the instrument, or the sensor using a Field Communicator with device descriptions (DDs) compatible with DLC3010 digital level controllers. The Field Communicator may be connected at the digital level controller or at a field junction box. Using the Field Communicator, you can perform several operations with the DLC3010 digital level controller. You can interrogate, configure, calibrate, or test the digital level controller. Using the HART protocol, information from the field can be integrated into control systems or be received on a single loop basis. DLC3010 digital level controllers are designed to directly replace standard pneumatic and electro-pneumatic level transmitters. DLC3010 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They mount on other manufacturers’ displacer type level sensors through the use of mounting adaptors.
249 Caged Sensors (see table 1-6)
D249, 249B, 249BF, 249C, 249K, and 249L sensors side-mount on the vessel with the displacer mounted inside a cage outside the vessel. (The 249BF caged sensor is available only in Europe, Middle East, and Africa.)
249 Cageless Sensors (see table 1-7)
D249BP, 249CP, and 249P sensors top-mount on the vessel with the displacer hanging down into the vessel. D249VS sensor side-mounts on the vessel with the displacer hanging out into the vessel. D249W wafer-style sensor mounts on top of a vessel or on a customer-supplied cage.
Specifications
Specifications for the DLC3010 digital level controller are shown in table 1-1. Specifications for the 249 sensor are shown in table 1-3.

Output Signal
Analog: 4-20 milliamperes DC (Jdirect action–increasing level, interface, or density increases output; or Jreverse action–increasing level, interface, or density decreases output)
High saturation: 20.5 mA Low saturation: 3.8 mA High alarm: 22.5 mA Low Alarm: 3.7 mA
Only one of the above high/low alarm definitions is available in a given configuration. NAMUR NE 43 compliant when high alarm level is selected.
Digital: HART 1200 Baud FSK (frequency shift keyed)
HART impedance requirements must be met to enable communication. Total shunt impedance across the master device connections (excluding the master and transmitter impedance) must be between 230 and 600 ohms. The transmitter HART receive impedance is defined as: Rx: 42K ohms and Cx: 14 nF
Note that in point-to-point configuration, analog and digital signalling are available. The instrument may be queried digitally for information, or placed in Burst mode to regularly transmit unsolicited process information digitally. In multi-drop mode, the output current is fixed at 4 mA, and only digital communication is available.

Operating Influences

Power Supply Effect: Output changes <±0.2% of full scale when supply varies between min. and max voltage specifications.

Transient Voltage Protection: The loop terminals are protected by a transient voltage suppressor. The specifications are as follows:

Ambient Temperature: The combined temperature effect on zero and span without the 249 sensor is less than 0.03% of full scale per degree Kelvin over the operating range -40 to 80_C (-40 to 176_F)
Process Temperature: The torque rate is affected by the process temperature (see figure 1-2 and 1-3). The process density may also be affected by the process temperature.
Process Density: The sensitivity to error in knowledge of process density is proportional to the differential density of the calibration. If the differential specific gravity is 0.2, an error of 0.02 specific gravity units in knowledge of a process fluid density represents 10% of span.

Minimum Differential Specific Gravity
With a nominal 4.4 degrees torque tube shaft rotation for a 0 to 100 percent change in liquid level (specific gravity=1), the digital level controller can be adjusted to provide full output for an input range of 5% of nominal input span. This equates to a minimum differential specific gravity of 0.05 with standard volume displacers.

Table 1-1. DLC3010 Digital Level Controller Specifications (continued)

Minimum Differential Specific Gravity (continued)

Electrical Connections

See 249 sensor specifications for standard displacer volumes and standard wall torque tubes. Standard volume for 249C and 249CP sensors is 980 cm3 (60 in3), most others have standard volume of 1640 cm3 (100 in3).
Operating at 5% proportional band will degrade accuracy by a factor of 20. Using a thin wall torque tube, or doubling the displacer volume will each roughly double the effective proportional band. When proportional band of the system drops below 50%, changing displacer or torque tube should be considered if high accuracy is a requirement.
Mounting Positions
Digital level controllers can be mounted right- or left-of-displacer, as shown in figure 2-5.
Instrument orientation is normally with the coupling access door at the bottom, to provide proper drainage of lever chamber and terminal compartment, and to limit gravitational effect on the lever assembly. If alternate drainage is provided by user, and a small performance loss is acceptable, the instrument could be mounted in 90 degree rotational increments around the pilot shaft axis. The LCD meter may be rotated in 90 degree increments to accommodate this.

Two 1/2-14 NPT internal conduit connections; one on bottom and one on back of terminal box. M20 adapters available.

DLC3010 Digital Level Controller Installation
August 2020

Section 2 Installation2-2-
This section contains digital level controller installation information including an installation flowchart (figure 2-1), mounting and electrical installation information, and a discussion of failure mode jumpers.
Configuration: On the Bench or in the Loop
Configure the digital level controller before or after installation. It may be useful to configure the instrument on the bench before installation to ensure proper operation, and to familiarize yourself with its functionality.
Protecting the Coupling and Flexures
CAUTION
Damage to flexures and other parts can cause measurement errors. Observe the following steps before moving the sensor and controller.
Lever Lock
The lever lock is built in to the coupling access handle. When the handle is open, it positions the lever in the neutral travel position for coupling. In some cases, this function is used to protect the lever assembly from violent motion during shipment. A DLC3010 controller will have one of the following mechanical configurations when received: 1. A fully assembled and coupled caged-displacer system shipped with the displacer or driver rod blocked within the
operating range by mechanical means. In this case, the access handle (figure 2-4) will be in the unlocked position. Remove the displacer-blocking hardware before calibration. (See the appropriate sensor instruction manual). The coupling should be intact.
CAUTION
When shipping an instrument mounted on a sensor, if the lever assembly is coupled to the linkage, and the linkage is constrained by the displacer blocks, use of the lever lock may result in damage to bellows joints or flexure.
2. If the displacer cannot be blocked because of cage configuration or other concerns, the transmitter is uncoupled from the torque tube by loosening the coupling nut, and the access handle will be in the locked position. Before placing such a configuration into service, perform the Coupling procedure found on page 39.
3. For a cageless system where the displacer is not connected to the torque tube during shipping, the torque tube itself stabilizes the coupled lever position by resting against a physical stop in the sensor. The access handle will be in the unlocked position. Mount the sensor and hang the displacer. The coupling should be intact.

4. If the controller was shipped alone, the access handle will be in the locked position. All Mounting, Coupling and Calibration procedures must be performed.
The access handle includes a retaining set screw, as shown in figures 2-4 and 2-6. The screw is driven in to contact the spring plate in the handle assembly before shipping. It secures the handle in the desired position during shipping and operation. To set the access handle in the open or closed position, this set screw must be backed out so that its top is flush with the handle surface.

Mounting
WARNING
To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation operations.
Personal injury or property damage due to sudden release of pressure, contact with hazardous fluid, fire, or explosion can be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not be readily apparent when disassembling the sensor or removing the displacer. Before disassembling the sensor or removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.
Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

Hazardous Area Classifications and Special Instructions for “Safe Use” and Installations in Hazardous Locations
Refer to the DLC3010 Quick Start Guide (D103214X012) that ships with the instrument for Hazardous Area Classifications and Special Instructions for “Safe Use” and Installations in Hazardous Locations. If a copy of this quick start guide is needed contact your Emerson sales office or go to Fisher.com.
Mounting the 249 Sensor
The 249 sensor is mounted using one of two methods, depending on the specific type of sensor. If the sensor has a caged displacer, it typically mounts on the side of the vessel as shown in figure 2-2. If the sensor has a cageless displacer, the sensor mounts on the side or top of the vessel as shown in figure 2-3.
The DLC3010 digital level controller is typically shipped attached to the sensor. If ordered separately, it may be convenient to mount the digital level controller to the sensor and perform the initial setup and calibration before installing the sensor on the vessel.
Note Caged sensors have a rod and block installed on each end of the displacer to protect the displacer in shipping. Remove these parts before installing the sensor to allow the displacer to function properly.

Note
If alternate drainage is provided by the user, and a small performance loss is acceptable, the instrument could be mounted in 90 degree rotational increments around the pilot shaft axis. The LCD meter may be rotated in 90 degree increments to accommodate this.

The digital level controller and torque tube arm are attached to the sensor either to the left or right of the displacer, as shown in figure 2-5. This can be changed in the field on the 249 sensors (refer to the appropriate sensor instruction manual). Changing the mounting also changes the effective action, because the torque tube rotation for increasing level, (looking at the protruding shaft), is clockwise when the unit is mounted to the right of the displacer and counter- clockwise when the unit is mounted to the left of the displacer.
All caged 249 sensors have a rotatable head. That is, the digital level controller can be positioned at any of eight alternate positions around the cage as indicated by the position numbers 1 through 8 in figure 2-5. To rotate the head, remove the head flange bolts and nuts and position the head as desired.

Electrical Connections
WARNING
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage from fire or explosion. Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval. Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or explosion.

Proper electrical installation is necessary to prevent errors due to electrical noise. A resistance between 230 and 600 ohms must be present in the loop for communication with a Field Communicator. Refer to figure 2-9 for current loop connections.

NOTE: 1THIS REPRESENTS THE TOTAL SERIES LOOP RESISTANCE.
E0363

Power Supply
To communicate with the digital level controller, you need a 17.75 volt DC minimum power supply. The power supplied to the transmitter terminals is determined by the available supply voltage minus the product of the total loop resistance and the loop current. The available supply voltage should not drop below the lift-off voltage. (The lift-off voltage is the minimum “available supply voltage” required for a given total loop resistance). Refer to figure 2-10 to

LIFT-OFF SUPPLY VOLTAGE (VDC)

If the power supply voltage drops below the lift-off voltage while the transmitter is being configured, the transmitter may output incorrect information. The DC power supply should provide power with less than 2% ripple. The total resistance load is the sum of the resistance of the signal leads and the load resistance of any controller, indicator, or related pieces of equipment in the loop. Note that the resistance of intrinsic safety barriers, if used, must be included.
Field Wiring
Note For intrinsically safe applications, refer to the instructions supplied by the barrier manufacturer.

WARNING
To avoid personal injury or property damage caused by fire or explosion, remove power to the instrument before removing the digital level controller cover in an area which contains a potentially explosive atmosphere or has been classified as hazardous.
All power to the digital level controller is supplied over the signal wiring. Signal wiring need not be shielded, but use twisted pairs for best results. Do not run unshielded signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. If the digital controller is in an explosive atmosphere, do not remove the digital level controller covers when the circuit is alive, unless in an intrinsically safe installation. Avoid contact with leads and terminals. To power the digital level controller, connect the positive power lead to the + terminal and the negative power lead to the – terminal as shown in figure 2-11.

CAUTION
Do not apply loop power across the T and + terminals. This can destroy the 1 Ohm sense resistor in the terminal box. Do not apply loop power across the Rs and — terminals. This can destroy the 50 Ohm sense resistor in the electronics module.

When wiring to screw terminals, the use of crimped lugs is recommended. Tighten the terminal screws to ensure that good contact is made. No additional power wiring is required. All digital level controller covers must be fully engaged to meet explosion proof requirements. For ATEX approved units, the terminal box cover set screw must engage one of the recesses in the terminal box beneath the terminal box cover.
Grounding
WARNING
Personal injury or property damage can result from fire or explosion caused by the discharge of static electricity when flammable or hazardous gases are present. Connect a 14 AWG (2.1 mm2) ground strap between the digital level controller and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements.

The digital level controller will operate with the current signal loop either floating or grounded. However, the extra noise in floating systems affects many types of readout devices. If the signal appears noisy or erratic, grounding the current signal loop at a single point may solve the problem. The best place to ground the loop is at the negative terminal of the power supply. As an alternative, ground either side of the readout device. Do not ground the current signal loop at more than one point.
Shielded Wire
Recommended grounding techniques for shielded wire usually call for a single grounding point for the shield. You can either connect the shield at the power supply or to the grounding terminals, either internal or external, at the instrument terminal box shown in figure 2-11.

Power/Current Loop Connections
Use ordinary copper wire of sufficient size to ensure that the voltage across the digital level controller terminals does not go below 12.0 volts DC. Connect the current signal leads as shown in figure 2-9. After making connections, recheck the polarity and correctness of connections, then turn the power on.
RTD Connections
An RTD that senses process temperatures may be connected to the digital level controller. This permits the instrument to automatically make specific gravity corrections for temperature changes. For best results, locate the RTD as close to the displacer as practical. For optimum EMC performance, use shielded wire no longer than 3 meters (9.8 feet) to connect the RTD. Connect only one end of the shield. Connect the shield to either the internal ground connection in the instrument terminal box or to the RTD thermowell. Wire the RTD to the digital level controller as follows (refer to figure 2-11):
Two-Wire RTD Connections
1. Connect a jumper wire between the RS and R1 terminals in the terminal box. 2. Connect the RTD to the R1 and R2 terminals.
Note During Manual Setup, you must specify the connecting wire resistance for a 2-wire RTD. 250 feet of 16 AWG wire has a resistance of 1 ohm.

Three-Wire RTD Connections
1. Connect the 2 wires which are connected to the same end of the RTD to the RS and R1 terminals in the terminal box. Usually these wires are the same color.
2. Connect the third wire to terminal R2. (The resistance measured between this wire and either wire connected to terminal RS or R1 should read an equivalent resistance for the existing ambient temperature. Refer to the RTD manufacturer’s temperature to resistance conversion table.) Usually this wire is a different color from the wires connected to the RS and R1 terminals.
Communication Connections
WARNING
Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in an area which contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of the terminal box cap before proceeding.
The Field Communicator interfaces with digital level controller from any wiring termination point in the 4­20 mA loop (except across the power supply). If you choose to connect the HART communicating device directly to the instrument, attach the device to the loop + and – terminals inside the terminal box to provide local communications with the instrument.

Test Connections
WARNING
Personal injury or property damage caused by fire or explosion may occur if the following procedure is attempted in an area which contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of the terminal box cap before proceeding.
Test connections inside the terminal box can be used to measure loop current across an internal 1 ohm resistor. 1. Remove the terminal box cap. 2. Adjust the test meter to measure a range of 0.001 to 0.1 volts. 3. Connect the positive lead of the test meter to the + connection and the negative lead to the T connection inside the
terminal box. 4. Measure Loop current as: Voltage (on test meter) 1000 = milliamps
example:
Test meter Voltage X 1000 = Loop Milliamps
0.004 X1000 = 4.0 milliamperes
0.020 X 1000 = 20.0 milliamperes 5. Remove test leads and replace the terminal box cover.
Multichannel Installations
You can connect several instruments to a single master power supply as shown in figure 2-12. In this case, the system may be grounded only at the negative power supply terminal. In multichannel installations where several instruments depend on one power supply, and the loss of all instruments would cause operational problems, consider an uninterruptible power supply or a back-up battery. The diodes shown in figure 2-12 prevent unwanted charging or discharging of the back-up battery. If several loops are connected in parallel, make sure the net loop impedance does not reach levels that would prevent communication.

To Additional Instruments

Note that to provide a 4-20 mA analog output signal, the DLC3010 must use HART polling address 0. Therefore, if a multichannel installation is used with all transmitters in 4-20 mA output mode, some means must be provided to isolate an individual transmitter for configuration or diagnostic purposes. A multichannel installation is most useful if the instruments are also in multi- drop mode and all signaling is done by digital polling.

Alarm Jumper
Each digital level controller continuously monitors its own performance during normal operation. This automatic diagnostic routine is a timed series of checks repeated continuously. If diagnostics detect a failure in the electronics, the instrument drives its output to either below 3.70 mA or above 22.5 mA, depending on the position (HI/LO) of the alarm jumper.
An alarm condition occurs when the digital level controller self-diagnostics detect an error that would render the process variable measurement inaccurate, incorrect, or undefined, or if the PV violates a user-defined alert threshold while a HiHi or LoLo PV monitor is enabled. At this point the analog output of the unit is driven to a defined level either above or below the nominal 4-20 mA range, based on the position of the alarm jumper.
On encapsulated electronics 14B5483X042 and earlier, if the jumper is missing, the alarm is indeterminate, but usually behaves as a FAIL LOW selection. On encapsulated electronics 14B5483X052 and later, the behavior will default to FAIL HIGH when the jumper is missing.
Alarm Jumper Locations
Without a meter installed
The alarm jumper is located on the front side of the electronics module on the electronics side of the digital level controller housing, and is labeled FAIL MODE.
With a meter installed
The alarm jumper is located on the LCD faceplate on the electronics module side of the digital level controller housing, and is labeled FAIL MODE.

Changing Jumper Position
WARNING
Personal injury or property damage caused by fire or explosion may occur if the following procedure is attempted in an area which contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of the instrument cover before proceeding.
Use the following procedure to change the position of the alarm jumper: 1. If the digital level controller is installed, set the loop to manual. 2. Remove the housing cover on the electronics side. Do not remove the cover in explosive atmospheres when the
circuit is alive. 3. Set the jumper to the desired position. 4. Replace the cover. All covers must be fully engaged to meet explosion proof requirements. For ATEX approved
units, the set screw on the transducer housing must engage one of the recesses in the cover.

Loop Test
Field Communicator Service Tools > Maintenance > Tests > Loop Test (3-4-1-2)
Loop test can be used to verify the controller output, the integrity of the loop, and the operations of any recorders or similar devices installed in the loop. To initiate a loop test, perform the following procedure:
1. Connect a reference meter to the controller. To do so, either connect the meter to the test connections inside the terminal box (see the Test Connections procedure) or connect the meter in the loop as shown in figure 2-9.
2. Access Loop Test. 3. Select OK after you set the control loop to manual.
The Field Communicator displays the loop test menu.
4. Select a discreet milliamp level for the controller to output. At the “Choose analog output” prompt, select 4 mA, 20 mA, or Other to manually input a value between 4 and 20 milliamps.
5. Check the reference meter to verify that it reads the value you commanded the controller to output. If the readings do not match, either the controller requires an output trim, or the meter is malfunctioning.
After completing the test procedure, the display returns to the loop test screen and allows you to choose another output value or end the test.

Commissioning the Digital Level Controller for use with the HART Tri-Loop
To prepare the digital level controller for use with a 333 HART Tri-Loop, you must configure the digital level controller to burst mode, and select the dynamic variables to burst. In burst mode, the digital level controller provides digital information to the HART Tri-Loop HART-to-Analog Signal Converter. The HART Tri-Loop converts the digital information to a 4-20 mA analog signal. The HART Tri-Loop divides the signal into separate 4-20 mA loops for the primary (PV), secondary (SV), and tertiary (TV) variables. Depending upon the burst option selected, the digital level controller will burst the variables as shown in table 2-1.
The DLC3010 status words are available in the HART Burst messages. However, the Tri-Loop cannot be configured to monitor them directly.
To commission a DLC3010 digital level controller for use with a HART Tri-Loop, perform the following procedure.

Ranging
DUpper Sensor Limit indicates the maximum usable value for a Range Value.
DLower Sensor Limit indicates the minimum usable value for a Range Value.
DMinimum Span is the difference between the Upper Range Value and the Lower Range Value below which amplification of instrument errors may become a concern. This effect should be considered when sizing displacer / torque tube.
DUpper Range Value defines the operational end point from which the Analog Value and the 100% point of the percent range are derived.
DLower Range Value defines the operational end point from which the Analog Value and the 0% point of the percent range are derived.
DAnalog Output Action is set to DIRECT when analog output increases with increasing process signal, and to REVERSE when analog output decreases with increasing process signal.
DChange Action allows you to change the output action by swapping values of the Upper Range Value and Lower Range Value. Action is DIRECT if the Upper Range Value is greater than the lower range value. Action is REVERSE if Lower Range Value is greater than Upper Range Value.
DLevel Offset is the Primary Variable value you want the instrument to report when physical level is at the bottom of displacer. It is only available in Level or Interface measurement mode.
DSet Level Offset adding a level offset permits the process variable value in engineering units to be reported with respect to a reference point other than the bottom of the displacer (see figure 3-1). Examples include: bottom of the process vessel, the process set point, or sea level. Set Level Offset is only available in Level or Interface measurement mode. Follow the prompts on the Field Communicator to enter the offset value. The procedure will offer to shift the range values and alert thresholds by the amount of the level offset for you. This will keep the 4-20 mA output aligned with the top and bottom of the displacer. If you have already shifted the range values and alert thresholds to account for the effect of the offset you are adding select No when asked if you want to ‘Proceed changing range values and alert thresholds’.

Alarm Type and Security
DAlarm Configuration
Alarm Jumper indicates the analog output commanded in an alarm condition, either Fail Lo (3.7 mA) or Fail Hi (22.5 mA).

Notes Consider the effect of an alarm annunciation on the process and set alarm jumper position accordingly.
When Output Action is ‘Direct’: A Hi alarm setting will result in an alarm- state output consistent with a very high process. A Lo alarm setting will result in an alarm-state output consistent with a very low process.
When Output Action is ‘Reverse’, these relationships are swapped.
This variable is not updated dynamically, Select Refresh Jumper if you have moved the jumper.
If the network is in Multi-Drop alarm annunciation is disabled and the device is not directly driving any effector, so jumper setting is not a concern.

Refresh Jumper allows you read the alarm jumper position.
Signal Levels displays the signal saturation or alarm conditions via Analog Output.
DSecurity
To setup and calibrate the instrument, Write Protect must be set to Not Write Protected. (Write protection is reset by a power cycle. If you have just powered up the instrument Writes will be enabled by default.) In AMS, go to Device Information in the Overview page. Select the Alarm Type and Security tab to change Write Protect.
Write Protect displays the protection setting; “Not Write Protected” allows configuration and calibration of the instrument, “Write Protected” indicates that configuration and calibration are not currently allowed.
Change Protection allows you to enable or disable configuration and calibration of the instrument.

Section 4 Configuration and Calibration 4-4-
Initial Setup
If a DLC3010 digital level controller ships from the factory mounted on a 249 sensor, initial setup and calibration is not necessary. The factory enters the sensor data, couples the instrument to the sensor, and calibrates the instrument and sensor combination.
Note If you received the digital level controller mounted on the sensor with the displacer blocked, or if the displacer is not connected, the instrument will be coupled to the sensor and the lever assembly unlocked. To place the unit in service, if the displacer is blocked, remove the rod and block at each end of the displacer and check the instrument calibration. (If the “factory cal” option was ordered, the instrument will be precompensated to the process conditions provided on the requisition, and will not appear to be calibrated if checked against room temperature 0 and 100% water level inputs). If the displacer is not connected, hang the displacer on the torque tube. If you received the digital level controller mounted on the sensor and the displacer is not blocked (such as in skid mounted systems), the instrument will not be coupled, to the sensor, and the lever assembly will be locked. Before placing the unit in service, couple the instrument to the sensor, then unlock the lever assembly. When the sensor is properly connected and coupled to the digital level controller, establish the zero process condition and run the appropriate zero calibration procedure under Partial Calibration. The Torque Rate should not need to be re-calibrated.
To review the configuration data entered by the factory, connect the instrument to a 24 VDC power supply as shown in figure 2-9. Connect the Field Communicator to the instrument and turn it on. Go to Configure and review the data under Manual Setup, Alert Setup, and Communications. If your application data has changed since the instrument was factory-configured, refer to the Manual Setup section for instructions on modifying configuration data.
For instruments not mounted on a level sensor or when replacing an instrument, initial setup consists of entering sensor information. The next step is coupling the sensor to the digital level controller. When the digital level controller and sensor are coupled, the combination may be calibrated.
Sensor information includes displacer and torque tube information, such as: DLength units (meters, inches, or centimeters) DVolume units (cubic inches, cubic millimeters, or milliliters) DWeight units (kilograms, pounds, or ounce) DDisplacer Length DDisplacer Volume DDisplacer Weight DDisplacer Driver Rod Length (moment arm) (see table 4-1)

Configuration Advice
Guided Setup directs you through initialization of configuration data needed for proper operation. When the instrument comes out of the box, the default dimensions are set for the most common Fisher 249 construction, so if any data is unknown, it is generally safe to accept the defaults. The mounting sense ‘instrument left or right of displacer’ – is important for correct interpretation of positive motion. The torque tube rotation is clockwise with rising level when the instrument is mounted to the right of the displacer, and counterclockwise when mounted to the left of the displacer. Use Manual Setup to locate and modify individual parameters when they need to be changed.

Preliminary Considerations
Write Protect
Field Communicator Overview > Device Information > Alarm Type and Security > Security > Change Protection (1-7-3-2-2)
To setup and calibrate the instrument, Write Protect must be set to Not Write Protected. Write Protect is reset by a power cycle. If you have just powered up the instrument Writes will be enabled by default.

Guided Setup
Field Communicator Configure > Guided Setup > Instrument Setup (2-1-1)
Note Place the loop into manual operation before making any changes in setup or calibration.
Instrument Setup is available to aid initial setup. Follow the prompts on the Field Communicator display to enter information for the displacer, torque tube, and digital measurement units. Most of the information is available from the sensor nameplate, shown in figure 4-1. The moment arm is the effective length of the driver rod and depends upon the sensor type. For a 249 sensor, refer to table 4-1 to determine driver rod length. For a special sensor, refer to figure 4-2.

1. Moment arm (driver rod) length is the perpendicular distance between the vertical centerline of the displacer and the horizontal centerline of the torque tube. See figure 4-2. If you cannot determine the driver rod length, contact your Emerson sales office and provide the serial number of the sensor. 2.This table applies to sensors with vertical displacers only. For sensor types not listed, or sensors with horizontal displacers, contact your Emerson sales office for the driver rod length. For other manufacturers’ sensors, see the installation instructions for that mounting.

1. Enter displacer length, weight, volume units and values, and driver rod (moment arm) length (in the same units chosen for displacer length) when prompted.
2. Choose Instrument Mounting (left or right of displacer, refer to figure 2-5).
3. Choose Torque Tube Material.

Note For interface applications using standard hardware, if the 249 is not installed on a vessel, or if the cage can be isolated, calibrate the instrument with weights, water, or other standard test fluid, in level mode. After calibrating in level mode, the instrument can be switched to interface mode. Then, enter the actual process fluid specific gravity(s) and range values. For an interface application with an overweight displacer, see the section of this manual on “Calibration with an Overweight Displacer”. If the 249 sensor is installed and must be calibrated in the actual process fluid(s) at operating conditions, enter the final measurement mode and actual process fluid data now.

a. If you choose “Liquid Level” or “Interface Level,” the default process variable units are set to the same units chosen for displacer length. You are prompted to key in the level offset. Range values will be initialized based on Level Offset and displacer size. The default upper range value is set to equal the displacer length and the default lower range value is set to zero when the level offset is 0.

b. If you choose “Liquid Density,” the default process variable units are set to “SGU” (Specific Gravity Units). The default upper range value is set to “1.0” and the default lower range value is set to “0.1”.

5. Select the desired output action: Direct or Reverse

Choosing “reverse acting” will swap the default values of the upper and lower range values (the process variable values at 20 mA and 4 mA). In a reverse acting instrument, the loop current will decrease as the process variable value increases.

6. You are given the opportunity to modify the default value for the process variable engineering units.

7. You are then given the opportunity to edit the default values that were entered for the upper range value (PV Value at 20 mA) and lower range value (PV Value at 4 mA).

PV alert deadband is initialized to 0.5% span.
PV alerts are all disabled. Temperature alerts are enabled.
DIf Liquid Density mode was chosen, setup is complete.
DIf Interface Level or Liquid Level mode was chosen, you are advised that process fluid data must be configured. You have the options of entering constant SG values or loading default steam tables during setup, or exiting the procedure and manually configuring the process data later.

Note
If you are using water or weights for calibration, enter a specific gravity of 1.0 SGU. For other test fluids, enter the specific gravity of the fluid used.

Detailed configuration of the process fluid and temperature compensation is provided in Configure > Manual Setup > Process Conditions > Fluid(s).
Coupling
If the digital level controller is not already coupled to the sensor, perform the following procedure to couple the digital level controller to the sensor.

1. Slide the access handle to the locked position to expose the access hole. Press on the back of the handle as shown in
   figure 2-4 then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent. 2. Set the displacer to the lowest possible process condition, (i.e. lowest water level or minimum specific gravity) or
   replace the displacer by the heaviest calibration weight.
   Note Interface or density applications with displacer/torque tube sized for a small total change in specific gravity are designed to be operated with the displacer always submerged. In these applications, the torque rod is sometimes resting on a stop while the displacer is dry. The torque tube does not begin to move until a considerable amount of liquid has covered the displacer. In this case, couple with the displacer submerged in the fluid with the lowest density and the highest process temperature condition, or with an equivalent condition simulated by the calculated weights. If the sizing of the sensor results in a proportional band greater than 100% (total expected rotational span greater than 4.4 degrees), couple the transmitter to the pilot shaft while at the 50% process condition to make maximum use of available transmitter travel ($6_). The Capture Zero procedure is still performed at the zero buoyancy (or zero differential buoyancy) condition.
   3. Insert a 10 mm deep well socket through the access hole and onto the torque tube shaft clamp nut. Tighten the clamp nut to a maximum torque of 2.1 NSm (18 lbfSin).
   4. Slide the access handle to the unlocked position. (Press on the back of the handle as shown in figure 2-4 then slide the handle toward the rear of the unit.) Be sure the locking handle drops into the detent.

Torque Tube
DTT Material displays the torque tube material currently stored in the instrument.
Note A sensor with an N05500 torque tube may have NiCu on the nameplate as the torque tube material.
DChange Material– selecting a material in this procedure loads the default torque rate temperature compensation for the specified torque tube material.
DEdit Compensation
TT Compensation– Each temperature-coefficient data pair may be edited. If using fewer than 10 data pairs, a “0.0” entry in the dependent variable slot terminates the table entry process. The firmware treats a zero entry in the dependent variable slot as an indication that the previous data point was the end of the table and that interpolation ends at that point. If only one data pair exists before the pair with the 0.0 dependent variable entry, the table is flat. It provides a constant output across the entire temperature range. Torque Comp Plot displays a graph of the compensation table. Pre-compensate Torque Rate– The stiffness of the torque tube varies with process temperature. The firmware does not implement dynamic temperature compensation of the torque rate. However, the compensation tables for this effect are stored in the device. The “Pre-compensate Torque Rate” procedure allows you to apply a fixed compensation factor, based on the target process temperature, to the torque rate value stored in the instrument. For example, if the sensor was calibrated at 70_F or a theoretical torque rate valid at 70_F was manually entered in the configuration, but the target process operating condition is 375_F, this procedure will compute an appropriate correction factor from the table for the selected torque tube material, and modify the stored torque rate by that factor. The calibration should then be more accurate at the target process temperature (with a corresponding degradation at 70_F). It is recommended that you document this action by entering appropriate text in the Description and/or Message fields of the device configuration, to facilitate reversing the compensation later, and to help prevent it from being applied twice. DTorque Rate displays the torque rate currently stored in the instrument.
DChange Torque Rate applies a rough, theoretical calibration to the torque tube when manipulation of the input is impossible
Instrument Mounting
Specify whether the instrument is mounted to the right or left of the displacer. See figure 2-5.

Change PV
Allow you to change the PV assignment. Select Level Units if the PV is level, Interface Units if the PV is Interface, or Density Units if the PV is Density.
Note If the PV assignment is changing to Level or Interface, go to the Process Fluid(s) menu and edit the configuration data for fluid density before returning the loop to Auto.

Ranging
Field Communicator Configure > Manual Setup > Ranging (2-2-3)
Follow the prompts on the Field Communicator to view or edit ranging information. DUpper Sensor Limit indicates the maximum usable value for a Range Value. DLower Sensor Limit indicates the minimum usable value for a Range Value. DMinimum Span is the difference between the Upper Range Value and the Lower Range Value below which
amplification of instrument errors may become a concern. This effect should be considered when sizing displacer / torque tube. DUpper Range Value defines the operational end point from which the Analog Value and the 100% point of the percent range are derived. The device will output 20 mA when the PV is equal to the Upper Range Value. DLower Range Value defines the operational end point from which the Analog Value and the 0% point of the percent range are derived. The device will output 4 mA when the PV is equal to the Lower Range Value. DChange Action allows you to change the analog output action: Direct/Reverse. For Reverse action, the Upper Range Value and Lower Range Value will be swapped. DLevel Offset is the Primary Variable value you want the instrument to report when physical level is at the bottom of displacer.
Note Level Offset and Set Level Offset are only available in Liquid Level or Interface Level measurement mode.
DSet Level Offset adding a level offset permits the process variable value in engineering units to be reported with respect to a reference point other than the bottom of the displacer (see figure 4-3). Examples include: bottom of the process vessel, the process set point, or sea level.
Follow the prompts on the Field Communicator to enter the offset value. The procedure will offer to shift the range values and alert thresholds by the amount of the level offset for you. This will keep the 4-20 mA output aligned with

You can enter up to 10 temperature and specific gravity pairs in the table. The table entry function is terminated by entering zero for the specific gravity. Keep this in mind when setting up a table for a upper fluid, such as steam, whose specific gravity approaches 0 at lower temperatures.
The resolution of the table entry for specific gravity is 5 decimal places. This means the smallest specific gravity value you can enter is 0.00001, which should be sufficient to allow a starting temperature around 15.6 _C (60 _F) for the steam specific gravity table.
The example set of tables given are generated by visually laying linear segments over a reference curve, and are not guaranteed to provide any particular accuracy. They are provided to illustrate the guidelines for developing your own table.
1. Establish a table for the fluid(s) you are using over the expected operating range of process temperature. This allows you to make best use of the maximum of ten points to obtain the accuracy you require. If your fluid specific gravity is very linear over the operating temperature range, two data points may be sufficient. (The correction algorithm provides linear interpolation between data points, and bounds the result at the table end points.)
2. Pick points closer together in regions of higher slope. 3. Pick linear segments that distribute the error equally on each side of the true curve.
Enter values in the specific gravity tables.
If using fewer than 10 data pairs, a “0.0” entry in the dependent variable slot terminates the table entry process. The firmware treats a zero entry in the dependent variable slot as an indication that the previous data point was the end of the table and that interpolation ends at that point. If only one data pair exists before the pair with the 0.0 dependent variable entry, the table is flat. It provides a constant output across the entire temperature range.
Enter Constant SG allows you to define fluid density/densities by constant values. No temperature compensation is applied.
Measure SG is only visible if PV is Liquid Level.

If specific gravity information for the process fluid is not available, an instrument and sensor combination that has been previously calibrated can be used to measure the fluid density. You must be able to manipulate the level and externally measure it to have the instrument measure the specific gravity. First capture a new zero reference angle at the zero process condition for the unknown fluid(s), then run this procedure. If the actual process application is Level, use a test level near 100% when measuring SG. If the actual process application is interface, the best differential SG measurement will be obtained at 50% interface level. Follow the prompts on the Field Communicator and the following procedure to measure specific gravity:
1. Set the control loop for manual control.
2. Adjust the liquid level as close as possible to the optimum value discussed above. 3. Enter the externally measured level, in engineering units.
After you press OK on the Field Communicator, the instrument begins calculating the specific gravity. You can then elect to use this value as the specific gravity for all level measurements. If you select No, the instrument uses the specific gravity entered under PV Setup, or the values from the specific gravity tables.
4. When finished measuring specific gravity, return the control loop to automatic control.
View/Edit SG Tables allows you to review or edit the configuration of density temperature compensation.

Device Identification
Field Communicator Configure > Manual Setup > Device Identification (2-2-5)
Follow the prompts on the Field Communicator display to view or edit information in the following fields. DTag (also called HART tag) is a unique name (up to eight characters) that identifies the physical instrument.
DInstrument Serial Number– Use this field to enter or view the serial number on the instrument nameplate, up to 12 characters.
DSensor Serial Number– Use this field to enter or view the sensor serial number. The sensor serial number is found on the sensor nameplate.
DFinal Assembly Number– A number that can be used to identify the instrument and sensor combination.
DDate provides a place to save the date of the last revision of configuration or calibration information. It has no impact on the operation of the controller or Field Communicator. The format, such as MM/DD/YYYY, will be controlled by the settings of the host operating system.
DDescription provides a longer user-defined electronic label to assist with more specific controller identification than is available with the HART tag. The descriptor may be up to 16 characters long and has no impact on the operation of the controller or HART-based communicator.
DMessage provides the most specific user-defined means for identifying individual controllers in multi-controller environments. it allows for 32 characters of information and is stored with the other configuration data. Message has no impact on the operation of the controller or the Field Communicator.
Communications
Field Communicator Configure > Manual Setup > Communications (2-2-6)
DPolling Address– If the digital level controller is used in a point-to-point configuration, the Polling Address is 0. When several devices are connected in the same loop, each device must be assigned a unique polling address. The Polling Address may be set to a value between 0 and 15. A device with polling address greater than 0 will operate in Multi-Drop mode, with output current fixed. Any process information from a device in Multi-Drop mode must be obtained via HART communication.
DBurst Mode– Enabling burst mode provides continuous communication from the digital level controller.
Note It may be difficult to make configuration adjustments to the DLC3010 while it is in burst mode, due to an increase in communication errors. To reconfigure the device, it is advisable to first disable burst mode.
Depending upon the burst option selected, the digital level controller will burst the variables as shown in table 4-4.

For the Field Communicator to be able to communicate with a device whose polling address is not 0, it must be configured to automatically search for all or specific connected devices.

DScan Device allows you to refresh the host copy of device configuration.

Instrument Display
Field Communicator Configure > Manual Setup > Instrument Display (2-2-7)
Follow the prompts on the Field Communicator display to view or edit what is visible in the instrument display.
DLCD Configuration– Select this parameter to indicate if the meter is installed. If the meter is physically installed, select Installed, then send the change to the instrument. When switching the setting from ‘Not Installed’ to ‘Installed’, the meter display will be activated immediately. However, if you change the setting to ‘Not Installed’ from ‘Installed’ just to disable the display without physically removing the meter, a device reset or power cycle will be required before the setting takes effect. The meter must be configured as ‘installed’ before you can set the display type or the decimal places.
DDisplay Mode is only visible if the meter is installed.
DChange Display Mode– Select the type of information the meter should display and how it should be displayed by selecting ‘Change display mode’. You can select for display:
PV displays the process variable (level, interface, or density) in engineering units.
PV/Process Temperature alternately displays the process variable in engineering units, the process temperature in the units selected under Temp Units (PV Setup), and the degrees of torque tube rotation.

% Range displays the process variable as a percent of span (determined by the LRV and URV).
PV/% Range alternately displays the process variable in engineering units and the process variable in percent of span.
DDecimal Places–Select the number of decimal places to display, up to four. Setting the value to zero puts the display in auto-scale mode. It will then display as many decimals places as will fit.
If PV/Proc Temp or PV/% Range is selected, the display alternates every two seconds between the selected readings. The meter also simultaneously displays the analog output signal using a percent of scale bar graph around the perimeter of the display face as shown in figure 4-6, no matter what display type is selected.

Alert Setup

DLC3010 Digital Level Controller Configuration
August 2020

Note Take care not to configure the low alert threshold for a signal to a higher value than its high threshold, or both high and low alerts for that signal could become active at the same time.
The following menus are available for configuring Alerts.
Primary Variable
Field Communicator Configure > Alert Setup > Primary Variable (2-3-1)

Note The HiHi and LoLo PV alerts provide a means to drive an effector to a safe condition if there is a process issue associated with a PV extreme. In a situation where operation with the vessel at empty or full state is a normal condition, enabling these alerts is not advisable. The electrical, hydraulic, or mechanical signal noise at these conditions can easily drive the alert in and out of trip state, randomly driving the output to the alarm current. In cases where the PV extreme does represent a condition to be avoided, the dead band can be increased for the PV alerts to make the behavior more like a hysteretic switch. For example, a HiHi alert threshold could be set at 95% level and the dead band increased to at least 10%. The alarm condition will then hold an outflow control valve fully open until the desired differential gap is achieved. When the alarm state clears after satisfying the dead band, the system will resume throttling control.
Follow the prompts on the Field Communicator display to view or edit the following primary variable alerts.
High Alerts
DHiHi Enable– On or Off. PV High High Alert Enable activates checking the primary variable against the PV High-High Threshold. The High High Alert is set if the primary variable rises above the PV High High Threshold Once the alert is set, the primary variable must fall below the PV High High Threshold by the PV Deadband before the alert is cleared. See figure 4-10.
DPV HiHi Threshold– Primary Variable HiHi Threshold is the value of the process variable, in engineering units, which, when exceeded, sets the Primary Variable High-High Alert.
DManage HiHi Alert– Method to coordinate Hi Hi alert configuration with alarm jumper and other alerts.
DHi Enable– On or Off. High Enable activates checking the primary variable against the PV High Threshold. The High Alert is set if the primary variable rises above the PV High Threshold. Once the alert is set, the primary variable must fall below the PV High Threshold by the PV Deadband before the alert is cleared. See figure 4-10.
DPV Hi Threshold– Primary Variable Hi Threshold is the value of the process variable, in engineering units, which, when exceeded, sets the Primary Variable High Alert.
DEdit Hi Threshold– Method to change the PV Hi Threshold. The entered value is checked against the other thresholds to help avoid overlap.
DPV Value is the current value of PV for reference.
DUpper Range Value is the value of URV for reference.
DLower Range Value is the value of LRV for reference.

Note If the Hi Hi Alert is enabled and tripped, the digital level controller output will go to 3.75 mA or 22.5 mA, depending on the position of the alarm jumper. Consider the effect of an alarm annunciation on the process, then set alarm jumper position accordingly.
When Output Action is ‘Direct’:
DA Hi alarm setting will result in an alarm-state output consistent with a very high process.
DA Lo alarm setting will result in an alarm-state output consistent with a very low process. When Output Action is ‘Reverse’, these relationships are swapped.
See figure 4-7 and 4-8 and examples below to clarify the shape of the Analog Output transfer function under various PV alert configurations. Note that the Low Alarm Current capability is not NAMUR NE 43 compliant.
Examples:
If the device is driving a valve in a series analog loop, you would normally want to use an alarm current value that will move the valve in the direction that clears the alarm situation. A Hi-Hi alarm condition should generate a signal that will stop a vessel from overflowing.
If the control valve is in the outflow or dump line you will want to open the valve. If the dump valve opens for an increasing current signal, you would select Plot A in figure 4-8 (HiHi Alert enabled, High Current alarm jumper position, Direct action).
To keep a vessel from overflowing when the control valve is in the inflow pipe, you will want to close the valve. If the fill valve opens for an increasing current signal, you would select Plot B in figure 4-8 (HiHi Alert enabled, Low Current alarm jumper position, Reverse action).
If the device is driving the input to a control system that uses NAMUR NE 43 levels to alarm, instead of directly driving a valve, you might choose the High Current alarm jumper position even for Reverse action (Plot D in figure 4-8), as the DLC3010 low current alarm isn’t low enough to guarantee a NAMUR NE 43 trip (Plots B and C in figure 4-8).
If the control system receiving the DLC3010 4-20 mA signal has its own PV alert thresholds and alarm strategy, you would probably disable the DLC3010’s internal HiHi PV alert and use only the control system’s PV alerts. (The DLC3010 hardware alerts would still drive the analog output signal to the Alarm Jumper setting in that case.)
In a Multi-Drop network (device has a non-zero Polling Address), alarm annunciation is disabled and the device is not directly driving any effector, so jumper setting is not a concern.
