1. INTRODUCTION
In addition to the 1/16 DIN (48 x 48 mm) design, the UNICONT PM universal controller family is characterized by easy setpoint adjustment and easy programming. The universal analog PID controller is suitable for processing signals from Pt100 resistance thermometers, various thermocouples, and transmitters with a 4…20 mA and 0…10 V DC, 0…5 V DC, 1…5 V DC, 0…100 mV DC signal. The control output can be a relay, a continuous 0…20 mA or 4…20 mA current signal, or an output suitable for operating an SSR (solid-state relay). The selflearning autotuning (AT) mode helps users determine PID parameters. The device provides automatic wire compensation for the Pt100 input signal and automatic cold junction compensation for the thermocouple input signal. Some PM­500 series members are also capable of RS485 communication. The UNICONT PM­500 enables more efficient control with a super- fast 50 ms sampling cycle and ±0.3% display accuracy. Moreover, it supports a variety of control modes, including simultaneous control of heating and cooling and automatic/manual control and communication functions.

Ally types have colored connection points. Other connection point types depend on the particular variant.

Important information for proper use:
­ The digital input is not electrically isolated from internal circuits, so it must be insulated if it is connected to another circuit.
­ Make sure that the connection polarity of the temperature sensor or analog input is correct. ­ Make sure the polarity of the power supply is correct. ­ Do not swap the output and input terminals. ­ For thermocouple sensors, use a compensation cable with the same specifications as the input sensors.
Using an extension cord of different specifications and/or materials makes temperature sensing less accurate. For more reliable operation, choosing a high-grade compensation cable is recommended. ­ Do not place sensor wires near AC wires. ­ Do not attach communication cables to the AC power cord. Use only twisted-pair wires for communication cabling. The length of the communication cable must not exceed 800 meters.

Analog

Note: If the input specification is changed, the upper / lower limits of the SV will be automatically set to the maximum/ minimum values of the new specification for the temperature sensors. For analog inputs, it sets the analog upper/lower input values to the max/min temperature range and the SV upper/lower limits to the upper/lower scale values. Therefore,
the settings need to be reconfigured.

5.3.2 Sensor Temperature Unit
When the input temperature sensor is selected, the [PAR3 – UNIT] can be set to display the desired unit (°C, °F). However, this parameter is not displayed when an analog input is selected. The default unit is °C When analog input is selected, it is possible to specify the unit [PAR3 – dUNT] (°C, °F,%, OFF). When OFF is selected, the displayed unit is not specified. The LED unit display does not turn on. The default setting is %.

5.3.3 Analog Input Scale Value Settings
By selecting the analog input, the analog input range (upper / lower input limits) and the display scale (upper / lower scale limits) within the selected input range can be set. For analog input, ±5% of the set upper / lower limit is extended. The analog output is also expanded by comparing the input value. (Using a ±5% extension for a temperature sensor input within the temperature range.)

Note: If the upper and lower limit scale settings are the same, ERR will flash twice, and the Setting mode will be displayed.

5.3.4 Low-Limit Input Value [PAR3 L-RG] The actually used lower limit values can be set within the analog input range. The temperature range from the minimum value to the upper limit [H-RG] – F.S. adjustable up to 10%. Default: 0.

5.3.5 Upper-Limit Input Value [PAR3 H-RG] The actually used limit values can be set within the analog input range. The lower input limit [L-RG] + F.S. can be set from 10% to the maximum value of the temperature range. Default: 10.

5.3.6 Scale Decimal Point Position [PAR3 DOT] The decimal point position can be set for Current Measured Value (PV) and Set Value (SV) on the upper and lower limit scales. Available settings: 0000 / 000.0 / 00.00 / 0.000. Default: 000.0.

5.3.7 Lower Limit Scale Value [PAR3 L-SC] Sets the display scales for the lower limits of the analog input [L-RG]. (Based on the decimal point setting.) Default: 0

5.3.8 Upper Limit Scale Value [PAR3 H-SC] Sets the display scales for the upper limits of the analog input [H-RG]. (Based on the decimal point setting.) Default: 100.

5.3.9 Input Offset Correction [PAR3 IN-B] This function is used to correct the offset provided by thermocouples, RTDs, or analog input devices. The input correction function is mainly used when the sensor cannot be fixed directly to the controlled objects. Temperature difference compensation must be performed between the sensor installation point and the actual measuring point. Default setting: 0, unit: °C / °F / -.
Example: If the controller shows 78 °C when the actual temperature is 80 °C, set the input correction [IN-B] to “002” to set the temperature displayed on the controller to 80 °C.
Note: If the Process Value (PV) of each input sensor after input correction is out of the input range, “HHHH” or “LLLL” will appear on the display. Make sure that an accurate temperature variance measurement is performed before setting the input correction. Inaccurate initial measurement may result in greater deviation.

5.3.10 Input Digital Filter [PAR3 MAvF] Stable control is not possible if the Process Value (PV) fluctuates due to rapid input signal changes. Using the input digital filter function stabilizes the PV for more reliable control. Default setting: 0.1 s. Example: If the digital input filter is set to 0.4 seconds, the digital filter applies to the sampling value collected in 0.4 seconds. (400 ms).
Note: The Process Value (PV) may differ from the actual input value when using the digital input filter.
5.3.11 Upper Limit [PAR3 H-SV] and Lower Limit of Set Value (SV) [PAR3 L-SV] The Set Value (SV) range can be limited within the temperature range of the temperature sensor or analog input to prevent system control by improper SV.

Note: Setting values outside the min/max input range or analog upper/lower limits is impossible. The previous settings are retained instead of such values. The Setpoint (SV) can only be set within the lower limit of SV [L-SV] and the upper limit of SV [H-SV]. The lower limit of SV [L-SV] must not exceed the upper limit of SV [H-SV].

5.4 OUTPUT SETTINGS
5.4.1 Control output (OUT1/OUT2) selection [PAR3 OUT1/OUT2] On models with a current loop output, current (CURR) or SSR drive output can be selected.
Default setting: SSR.
If the OUT1, OUT2 are relay output type, the OUT1, O1SR, O1MA, OUT2, O2SR, and O2MA parameters are unavailable.
5.4.2 SSRP function [PAR3 O1SR] SSRP function of SSR drive output is selectable one of standard ON/OFF control, cycle, phase control. By parameter setting, standard SSR drive is available. Also, cycle control connecting with a zero cross turn-on method SSR, phase control connectiong with a random turn- on method SSR are available.
Realizing high accuracy and cost effective temperature control with both current output (4-20mA) and linear output(cycle control and phase control).
If the OUT1, OUT2 output is set to current + SSR drive, and the OUT1, OUT2 output setting is SSR, then the O1SR, O2SR output setting is kept in STND, and the parameter is not displayed.
If OUT1 is set to SSRP function SSR drive output and OUT2 output is set to current or SSR drive output, then OUT1, O1MA will not be displayed. Possible settings for O1SR: STND, CYCL, PHAS. If the O2SR parameter is set to SSR, it is held in STND, and the parameter is not displayed.

In case of selecting SSRP function whether cycle output [CYCL] or phase output [PHAS] with PID control type, control cycle is not available to set.

5.4.3 Current output range settings [PAR3 O1MA/O2MA]

If the control output is set to current output, you can select upper and low- limit range for the current output as either 4…20 mA or 0…20 mA.

O1MA: Sets OUT1’s current output range.

O2MA: Sets OUT2’s current output range.

Note: This parameter is only available on models supporting current output [OUT1, OUT2].

5.5 CONTROL OUTPUT Output modes for general temperature control include heating mode or cooling mode and heating and cooling mode. Heating control and cooling control are opposite operations with inverted outputs. The PID time constant varies depending on the characteristics of the section controlled during PID control. The value of the control output is MV (Manipulated Variable). MV is a percentage value that controls the switching of the assigned device output according to the settings.

5.5.1 Heating Control [PAR3 O-FT HEAT] or Cooling Control [PAR3 O-FT COOL] Heating control mode: If the Process Value (PV) falls below the Set Value (SV), the output will power the heater. Cooling control Mode: If the Process Value (PV) rises above the Set Value (SV), the output will power the cooler.
5.5.2 Heating & Cooling Control [PAR3 O-FT H-C] Heating and cooling control mode: heating and cooling with a single temperature controller if it is difficult to control the temperature of the object by heating or cooling alone. The heating and cooling control mode uses different PID time constants to control heating and cooling. It is possible to set the heating and cooling control in both PID control and ON / OFF control modes.
For heating and cooling control, the relay control output OUT1 is assigned to the heating control, and the SSR / current control output OUT2 is assigned to the cooling control. Note that the OUT2 SSR drive output uses standard (on / off) control.
Note: For the OUT2 SSR/Curr and relay version, the output is controlled in [H-C] mode, the selection menu items are only displayed in this setting. When switching from each control mode [H-C, HEAT, COOL], the settings for the control mode return to the default setting, the set temperature value is retained.
If OUT2 is a relay version, the alarm output 3 (AL3) only works when the [O-FT] output control is set to heating (HEAT) or cooling (COOL) mode, then OUT2 will be used as an alarm output.
If the OUT2 SSR/Curr version and [SSR] is selected, and the control mode is (O-FT) [HEAT] or [COOL], the output is always active.
If the OUT2 SSR/Curr version and [Curr] is selected, and the output control mode is [HEAT] or [COOL], then OUT2 works as a current transmitter and is active all the time.

5.5.3 Deadband/Overlap Band [PAR2 DB] It is possible to assign a deadband between the heating and cooling control bands based on the Set Value (SV) for heating and cooling. A deadband is formed around the SV when a positive (+) value is set. There is no regulation in the deadband, so the heating and cooling MV (Manipulated Variable) will be 0.0% in the deadband formed. When the negative (-) value is set, an overlap band (simultaneous heating and cooling MVs) is formed around the SV.
Set to 0 if no deadband or overlap band is used.
When setting the integral time, this applies if the integral time for the heating control and cooling control is set. It also acts as a P-P controller for PI-P control and P-PI control.
Ranges and default settings:
[OUT1 / OUT2]: PID / PID, PID / ON-OFF, and ON-OFF / PID control

­ Set the range (temperature): ­ (proportional band) + (proportional band) (lower value when using different proportional bands)

Note: The same MV limits apply during auto-tuning. The MV limits do not apply to manual control, MV when control is stopped, MV sensor failure, and initial manual control. The MV upper / lower limit configuration is not available in the ON / OFF standard control mode (heating or cooling control).
5.5.5 MV Settings for Sensor Break Error [OPEN] [PAR5 ErMV] In the event of an open sensor error, the output value of the controller can be set to a predefined MV value instead of ON / OFF or PID control. Ignores the MV based on the ON / OFF or PID control and sends a control value based on the specified MV. Default setting: 0.0%
5.5.6 RAMP Settings [PAR2 RAMU/ RAMD/ rUNT] The ramp is a function that configures the temperature per unit time to the Setpoint (SV). The function limits the rate of change of the Set Value (SV) and thus limits sudden temperature changes (increase and decrease) in the control system. The ramp is typically used in applications where rapid temperature changes (increase and decrease) can adversely affect the controlled system. Control is based on the changed SV (hereafter: RAMP SV) ­ based on the preset rate of change (temperature changing per unit time). The RAMP uplink rate and the RAMP downlink rate can be configured independently.

Description / Range
Setting for RAMP-UP change rate Setting for RAMP-DOWN change rate RAMP time unit (SEC / MIN / HOUR)

Default 0 °C / °F / Digit MIN

Note: Activating the RAMP function when RAMP is not operating limits the Set Value (SV) rate of change based on the Process Value (PV). Changing the SV or RAMP parameters during RAMP operation limits the rate of change of SV based on SV at the time of change.

The alarm occurs during the RAMP based on the final SV. Setting the RAMP rate to 0 turns off the RAMP function. When the RAMP function is on, RAMP SV appears in the SV display area.

5.5.7 Auto/Manual control settings The automatic mode is for the temperature to reach SV with the MV value calculated by the PID control. The purpose of the manual mode is for the temperature to reach SV with a user-defined MV value.
Note: In manual mode, parameter settings can only be viewed and cannot be changed (except for lock parameters). If the [DI-1] digital input terminal function is set to automatic / manual [MAN], the button and automatic/manual changeover will not work with communication. If the unit is turned on after a power failure or shutdown, the previous mode (automatic or manual) will be retained.
It is possible to switch to manual mode during STOP state. It is also possible to switch between automatic / manual mode during adjustment, but automatic tuning will stop if manual control is switched on during automatic tuning. If a sensor break alarm occurs in [SBA] normal mode, the MV [ErMV] sensor fault will occur. The MV settings for manual and automatic control can be changed in this state.
Operational priority: Manual control > Stop > Open (sensor disconnected)
5.5.7.1 Switching Between Manual/Auto Control
Switching to manual mode for standard control (heating or cooling):
­ In `Normal’ mode, press the button, and the device will switch to MV monitoring mode. The SV display shows H (heating control) or C (cooling control) and shows MV, indicating the start of MV monitoring.

Note: After heating and cooling control, the system returns to automatic control in the order of heating monitoring, manual heating control, cooling monitoring, and manual cooling control. To switch between automatic and manual mode, press the
button once. The heating MV remains valid during cooling monitoring and manual cooling control. When the [DI-1] digital input function is set to AUTO / MANUAL [MAN], the button on the front panel and the auto / manual control functions via communication do not work.
Switching Manual / Auto control using the digital input (DI) connector: If the digital input function [DI-1] AUTO / MANUAL control switch is set to [MAN], turn on the DI to activate manual mode (the MAN indicator lights up) and turn off the DI to activate automatic mode. If the digital input function is automatic, it can only be monitored. If it is manual, it is possible to change the MV and monitor it.
Note: See 5.10.6 Digital Input for detailed information about the digital input (DI) terminal settings.
5.5.7.2 Initial MV for Manual Control [PAR5 ItMV] The initial MV value can be set when the device is switched from automatic [AUTO] to manual control [PrMU]. Default setting: AUTO.
­ AUTO: automatically adjusted MV, as initial MV for manual control. ­ PrMV: manually set initial MV [PrMV]. Note: When the power is turned back on, it starts with MV that was in use when the power was turned off.

Hysteresis [PAR2 hHYS/hOFT/cHYS/cOFT] Hysteresis is the setting of the control output on and off point in ON / OFF mode. ON_Hysteresis sets the output to an ON point, and OFF_Offset sets an off point. The values are set in °C / °F.

If the hysteresis is set too low, the disturbing characteristics that affect the device (noise, etc.) will turn the output control (compared to the control characteristics) uncertainly on and off, which should be avoided. To minimize this condition, adjust the ON_Hysteresis and OFF_Offset values according to the control characteristics (e.g., heater or cooling capacity and temperature) and the operator response, sensor response characteristics, and
installation conditions.

5.6.3 PID Control [PAR3 C-MD PID] PID control is a combination of the proportional (P), integral (I), and differential (D) control and provides excellent control over the devices, even with a delay time. The device uses the same PID time constant for SV0… SV1.
Proportional control (P) follows the set control value well with a small error; integral control (I) automatically corrects the error, and differential control (D) accelerates the response to the control. Through these operations, PID control achieves ideal temperature control.

5.6.3.1 Setting the Proportional Band for Heating [PAR2 H-P] and Cooling [PAR2 C-P] If the Process Value (PV) is within the proportional band (P), the ON / OFF ratio must be adjusted during the proportional period (T). The defined proportional control (time proportional control) section is called the proportional band. Default value: 10.0. It is set in °C / °F / %.

5.6.3.2 Setting Integral Time for Heating [PAR2 H-I] and Cooling [PAR2 C-I] MVs from integrative and proportional operation become identical if the deviation is consistent. The time required for the two MVs to match is called the integral time. Default value: 0 s.
Note: Integration does not occur if the integral time is set to 0. Setting the integral time too short can increase correction movements and cause control oscillations.

5.6.3.3 Setting Derivative Time for Heating [PAR2 H-D] and Cooling [PAR2 C-D] According to the difference of the ramp, the MV obtained from the derivative operation and the time required to reach the MV obtained from the proportional control are called the derivative time.
Note: The differentiation member stops when the derivative time is set to 0.

5.6.3.4 Setting Control Period for Heating [PAR3 H-T] and Cooling [PAR3 C-T] If a relay or SSR is used with control proportional to the MV output, the output will be on for a period of time (within the control period, as a percentage of the MV) and will remain off for the rest of the time. The preset period when the output is ON / OFF is called the proportional control period. Control with SSR drive output is faster than relay output. Therefore, setting a shorter control period can achieve more sensitive temperature control. Default ­ Relay: 20.0 s / SSR: 2.0 s.
Note: If heating and cooling control is used, configure the control period for heating and cooling separately.

5.6.3.5 Offset Correction / Manual Reset Settings [PAR2 REST] When selecting the P / PD control mode, there are some temperature differences even after the PV is stable because the temperature rise and fall times of the heater are inconsistent with the thermal characteristics of the controlled section, such as heat capacity and heater capacity. This temperature difference is called OFFSET. The offset can be corrected by manual reset. Default: 50%

Manual reset settings based on control results:

Under stable control conditions, set the offset to 50% if PV and SV are the same, above 50.0% if PV is lower than

SV, and below 50.0% if

PV is higher than SV.

Set reset under 50!

Set reset over 50!

Note: offset correction can only be used if proportional control (P) is on. If the integral value is set to 0, the manual reset
parameter is displayed. The user cannot configure the manual reset setting during heating and cooling control. Instead, the setting is automatically set to 0% for heating and cooling. Only applicable if the integration time is set to 0 during P or PD control. Switching from heating and cooling control to normal control (P, PD control) automatically sets the reset
settings to 50%

5.6.4 Auto-Tuning Automatic tuning measures the controlled section’s temperature characteristics and thermal response rate and then determines the required PID time constants. (If the [C-MD] control type is PID, it is displayed.)
This operation will stop automatically if an [OPEN] error occurs during auto- tuning. To stop auto-tuning, change the setting to OFF. (In this case, the P, I, D values before auto-tuning are retained.)

5.6.4.1 Auto-Tuning ON/OFF [PAR2 AT] Auto Tuning automatically stores the PID time constants when completed. These PID time constants can then be modified according to their usage environment. Default setting: OFF. When auto-tuning is in progress, the AT indicator on the controller’s front flashes every 1 second. When autotuning is completed, the AT indicator will automatically turn off, and the auto-tuning parameter will return to the OFF position.
Note: When auto tuning is in progress, and the [DI-K] digital input button function is set to RUN / STOP [STOP] or auto-tuning RUN / STOP [AT] and the digital input terminal [DI-1] function switches RUN / STOP [STOP] or AUTO / MANUAL control selection [MAN], auto-tuning stops automatically when the affected DI is entered, or a sensor disconnection error occurs. (Resets the PID used before auto-tuning).

Setting OFF ON

Description Auto-tuning is off or finished Auto-tuning is in progress

Note: Auto-tuning will continue even if the temperature value exceeds or falls within the input range. When auto-tuning is in progress, the parameters can only be referenced but not modified. Auto-tuning is not available for manual control.

5.6.5 Auto-Tuning Mode Settings [PAR3 AtT] Auto tuning is available in [TUN1] mode (based on SV) or [TUN2] mode (based on 70% of SV), depending on the default

5.7.6 Alarm Output Delay Settings [PAR4 A1ON / A1OF] The alarm output delay can be set to prevent false alarms caused by faulty input signals due to interference or noise. The default setting for both parameters: 0 s.
If there is a preset delay time, the alarm output will not turn on for the preset time. Instead, the front alarm indicator flashes every 0.5 seconds.

Parameter A1ON

Description
Alarm Output 1 on Delay: In the event of an alarm event, it is on standby for a preset period of time, checks the conditions for activating the alarm, and turns on the alarm output if the conditions persist.

A1OF

Alarm Output 1 Off Delay: After the alarm output is turned off, it is ready for a preset period, checks the alarm trigger conditions, and turns off the alarm output if the deactivation conditions continue.

5.7.7 Loop Break Alarm (LBA) [PAR4 AL-1/ LBA] Diagnose the control loop by monitoring the temperature change in the control circuit and send alarms if necessary. ­ Heating control: If the MV control output is 100% or the upper limit [H-MV] and the PV does not exceed the LBA detection band [LBaB] during the LBA monitoring time [LBaT], or if the control output MV is 0% or lower limit [L-MV] and PV do not fall below the LBA detection band [LBaB] during the LBA monitoring time [LBaT], the alarm output will turn on. ­ Cooling control: If the MV control output is 0% or lower limit [L-MV] and the PV does not increase at the LBA detection band [LBaB] during the LBA monitoring time [LBaT], or if the control output MV is 100% or upper limit [H-MV] and PV do not fall below the LBA detection band [LBaB] during the LBA monitoring time [LBaT], the alarm output will turn on.

Common reasons triggering the LBA output:

­ Sensor fault (disconnection, short circuit) ­ External control fault (magnet, auxiliary relay, etc.)

­ External load fault (heating, cooling, etc.) ­ Incorrect connection and disconnection of the external network.

5.7.10 Sensor Break Alarm [PAR4 AL-1 SBA] The controller can be set to send an alarm if no sensor is connected or it is disconnected during temperature control.
The sensor fault can be confirmed via an external alarm output contact, such as an audible signal or the like.
If the alarm operation is set to [AL-1] SBA, the sensor fault alarm will be activated.

Note: The alarm output option can be set to standard alarm [AL-A] or alarm latch [AL-B].
5.7.11 Heater Burnout Alarm [PAR4 AL-1 HBA] If a heater is used to increase the temperature of the controlled section, the PMG-500 temperature controller can be set to monitor the heater power supply and send an alarm if it detects a heater connection fault.
The device detects the power supply to the heater using a current transformer (CT) which converts the current to the heater to a specified ratio (CT ratio) for inspection. If the heating current [CT-A] measured by the CT is less than the setting value of the heating sensor [AL1L], the heater burnout alarm is activated.

Note: Heating element burnout is only detected when the temperature controller output is on. Otherwise, the controller will not detect the heater burnout. The heater burnout alarm function varies by model and control output type. The heatingand-cooling model can use the heating burnout alarm function in OUT1. Current detection does not occur if the control output time of OUT1 is less than 250 ms. The alarm output option can be set to standard alarm [AL-A] or alarm lock [AL-B].

pmg511en22p02

Heater burnout detection settings [PAR1 AL1L] Set the alarm output value [AL1L] as the reference value to detect the heater burnout. Default setting: 0.0. Unit: A.
Note: Set to 0.0 to turn off. Set to 50.0 to turn on.
Calculation of setting value Heating burnout set value = {(normal heating current) + (heating burnout current)} / 2
Example: If two output heaters (200 V AC, 1 kW, 5 A) are used, the normal heating current is 10 A (5 A × 2). If one of the heaters burns out, the heating current will be 5 A. The set value (10 A + 5 A) / 2 = 7.5 A). Heating current values below 7.5 A are considered to be a heating element burner and the alarm will turn on.

MtSV

Multi SV selection

If the DI-1 is set to Multi SV [MtSV], SV-0 is selected as SV when the terminal’s external contact is off and SV-1 is selected when the signal is switched on.
Note: When turned on, the digital input always checks the terminal input settings. The PGM­500 series has a limited number of terminals. Therefore, the digital input terminal1 (DI-1) is available. The Multi SV parameter is only activated if the Multi SV is at least 2. The digital input terminal function works independently of the lock and password settings [PAR5 PWD].

5.10.6.2 Digital Input Button Setting [PAR5 DI-K] To use the digital input button function, all functions must be first be assigned to the buttons. Default setting: STOP.

Setting STOP AlRE AT OFF

Description RUN / STOP Deactivate forced alarm output Automatic tuning RUN / OFF (for PID control) Not used

Note: If the digital input button and the digital input terminal are set the same, the digital input button will not work. To use the digital input button: In Normal mode, press and hold the + buttons for 3 seconds to perform the assigned function (deactivate run / stop or alarm output).
Note: If the same function is assigned to the digital input button and the digital input terminal, it is activated as an or function and deactivated as an ,,and” function. (However, this does not apply to the Multi SV function [MtSV] of the digital input terminals.) The digital input button functions work regardless of the password settings [PAR5 PWD]. 5.10.7 User Level Settings [PAR5 USER] Displaying the parameters can be restricted by setting the user level (normal or high).If set to standard user, only the main function parameters shaded in the complete parameter list are only displayed. Default setting: STND.

5.10.8 SV Group Lock [PAR5 LcSV]

The modification of SV parameters can be restricted by locking the SV group parameters, which include SV

selection, digital input button (

buttons for 3 seconds), button for monitoring and manual control,

parameter reset [INIT], and so on. Default setting: OFF.

5.10.10 Reset Parameter [INIT]

This function resets all parameters in the memory to the factory defaults.

Press and hold the

buttons on the front panel front panel for 5 seconds. The [INIT] parameter is

displayed. Select YES to reset the parameters. Default setting: NO.

Note: If the password function is enabled, a password must be entered to activate the function. Resetting the parameters also resets the password.

5.10.11 Password Settings [PAR5 PWD] The password setting applies to the functions in the SV group (except for the digital input key) and to parameters 1 to 5. Changing the password setting automatically activates password protection. However, setting the password to 0000 disables password protection. Default setting is 0000.

0001 is a read-only password. With this setting, the user can check the parameter settings without knowing the password. However, the user cannot change the parameters. If the [PWD] parameter is accessed with a readonly password, the encrypted form of the setting is displayed.

Settings: 1. Press and hold the

button in Normal mode.

2. Use the

buttons to select the [PAR5], then press the button.

3. Press the button to search the [PWD].

4. Select the desired digit with the button.

5. Use the

buttons to enter the password

(0000, 0002…9999), then press the button to save.

6. Repeat steps 4 and 5 and enter the preset password.

7. Press the button or do not press any button for at least 3 seconds to save the password

Note: 5.10.6 Digital Input functions are not affected by password protection settings.

5.10.11.1 Setting Up a Password [PASS] If password protection is enabled, access to SV parameters or groups when the device is in `Normal’ mode requires a password confirmation parameter [PASS]. Then the correct password must be entered to access the setting parameters.

Settings:

1. Access to the SV parameter or parameter group.

2. When prompted for [PASS], use the button to select the desired digit.

3. Use

buttons to enter the password (0001 to 9999), then press .

­ If the correct password is entered, the setting parameters will be accessible.

­ If an incorrect password is entered, repeat steps 2 and 3 and enter the correct password.

Note: If the password is unknown, enter 0001 to access the parameters in read- only mode. This parameter only appears if the setting of 5.10.11 Password Settings [PAR5 PWD] is set to a value other than 0000. If an incorrect password is entered, the SV display will show the encrypted form of the password stored by the user and an error message [ERR]. Then the error message flashes every 1 second.

5.10.11.2 Reset Password
Entering an incorrect password displays the encrypted form of the password on the SV display. Send this code to NIVELCO to recover a lost password.

Incorrect password entry (for example, the correct password is 1234).
1. Access to the SV parameter or parameter group. 2. When prompted by PASS, use the button to select the digit.

Use the

buttons to select 4321 (incorrect password), then press . Entering an incorrect pass-

word displays an encrypted password on the SV display. An ERR message is displayed and flashes at

1-second intervals.
