SAFETY PRECAUTIONS

All safety related codifications, symbols and instructions that appear in this operating manual or on the equipment must be strictly followed to ensure the safety of the operating personnel as well as the instrument.
If the equipment is not handled in a manner specified by the manufacturer it might impair the protection provided by the equipment.

Read complete instructions prior to installation and operation of the unit.

WARNING : Risk of electric shock.

WIRING GUIDELINES

WARNING :

1. To prevent the risk of electric shock power supply to the equipment must be kept OFF while doing the wiring arrangement. Do not touch the terminals while power is being supplied.
2. To eliminate electromagnetic interference use short wire with adequate ratings; twists of the same in equal size shall be made. For the input and output signal lines, be sure to use shielded wires and keep them away from each other.
3. Cable used for connection to power source, must have a 2 cross section of 1mm or greater. These wires shall have insulation capacity made of at least 1.5kV.
4. When extending the thermocouple lead wires, always use thermocouple compensation wires for wiring. For the RTD type, use a wiring material with a small lead resistance (5Ω max per line) and no resistance differentials among three wires.
5. A better anti-noise effect can be expected by using standard power supply cable for the instrument.

MAINTENANCE

1. The equipment should be cleaned regularly to avoid blockage of ventilating parts.
2. Clean the equipment with a clean soft cloth. Do not use Isopropyl alcohol or any other cleaning agent.

INSTALLATION GUIDELINES

1. This equipment, being built-in-type, normally becomes a part of main control panel and in such case the terminals do not remain accessible to the end user after installation and Internal wiring.
2. Do not allow pieces of metal, wire clippings, or fine metallic fillings from installation to enter the product or else it may lead to a safety hazard that may in turn endanger life or cause electrical shock to the operator.
3. Circuit breaker or mains switch must be installed between power source and supply terminals to facilitate power ‘ON’ or ‘OFF’ function. However this switch or breaker must be installed in a convenient position normally accessible to the operator.
4. Use and store the temperature controller within the specified ambient temperature and humidity ranges as mentioned in this manual.

CAUTION

1. When powering up for the first time, disconnect the output connections.
2. Fuse Protection : The unit is normally supplied without a power switch and fuses. Make wiring so that the fuse is placed between the mains power supply switch and the controller. (2 pole breaker fuse – rating : 275V AC,1A for electrical circuitry is highly recommended)
3. Since this is a built-in-type equipment (finds place in main control panel), its output terminals get connected to host equipment. Such equipment shall also comply with basic EMI/EMC and other safety requirements like EN61326-1 and EN 61010 respectively.
4. Thermal dissipation of equipment is met through ventilation holes provided on chassis of equipment. Such ventilation holes shall not be obstructed else it can lead to a safety hazard.
5. The output terminals shall be strictly loaded to the manufacturer specified values / range.

MECHANICAL INSTALLATION

1. Prepare the panel cutout with proper dimensions as shown above.
2. Fit the unit into the panel with the help of clamp given.
3. The equipment in its installed state must not come in close proximity to any heating sources, caustic vapors, oils, steam or other unwanted process by-products.
4. Use the specified size of crimp terminals (M3.5 screws) to wire the terminal block. Tighten the screws on the terminal block using the tightening torque within the range of 1.2 N.m.
5. Do not connect anything to unused terminals.

EMC GUIDELINES

1. Use proper input power cables with shortest connections and twisted type.
2. Layout of connecting cables shall be away from any internal EMI source.

LOAD CONNECTIONS

1. The service life of the output relays depends on the switching capacity and switching conditions. Consider the actual application conditions and use the product within the rated load and electrical service life.
2. Although the relay output is rated at 5 amps it is always necessary to use an interposing relay or contactor that will switch the load. This avoids damage to the controller in the event of a fault short developing on the power output circuit.
3. Always use a separate fused supply for the “power load circuit”and do not take this from the live and neutral terminals supplying power to the controller.

ELECTRICAL PRECAUTIONS DURING USE

Electrical noise generated by switching of inductive loads can create momentary disruption, erratic display, latch up, data loss or permanent damage to the instrument.

To reduce noise :

a) Use of snubber circuits across loads as shown above, is recommended.
b) Use separate shielded wires for inputs.

TERMINAL CONNECTIONS

Use only the correct thermocouple wire or compensating cable from the probe to instrument terminals avoiding joints in the cable if possible.
Failure to use the correct wire type will lead to inaccurate readings.
Ensure that the input sensor connected at the terminals and the input type set in the temperature controller configuration are the same.

USER GUIDE

1. Display Bias : This function is used to adjust the PV value in cases where it is necessary for PV value to agree with another recorder or indicator, or when the sensor cannot be mounted in correct location.

2. Filter Time Constant : The input filter is used to filter out quick changes that occur to the process variable in a dynamic or quick responding application which causes erratic control.
   The digital filter also aids in controlling processes where the electrical noise affects the input signal.
   Larger the value of FTC entered, greater the filter added and the slower the controller reacts to the process and vice versa.

3. Auto tune (AT) : The Auto-tuning function automatically computes and sets the proportional band (P), integral time (I), Derivative time (D), ARW% and cycle time (CY.T) as per process characteristics

   • Tune LED blinks at faster rate when auto-tuning is in progress.

   • At the completion of Auto-tuning, Tune LED stops blinking.

   • If the power goes OFF before auto-tuning is completed, auto-tuning will be restarted at next power ON.

   • If auto-tuning is not completed after 3-4 cycles, the autotuning is suspected to fail. In this case, check the wiring & parameters such as the control action, input type, etc.

   • Carry out the auto-tuning again, if there is a change in setpoint or process parameters.

4. ON/OFF control action (For Reverse Mode) :
   The relay is ‘ON’ up to the set temperature and cuts ‘OFF’ above the set temperature. As the temperature of the system drops, the relay is switched ‘ON’ at a temperature slightly lower than the set point
   HYSTERESIS :
   The difference between the temperature at which relay switches ‘ON’ and at which the relay switches ‘OFF’ is the hysteresis or dead band.

5. Manual Reset (for PID control & I = 0) : After some time the process temperature settles at some point and there is a difference between the set temperature & the controlled temperature. This difference can be removed by setting the manual reset value equal & opposite to the offset.

6. Self Tune (ST) : It is used where modification of PID parameters is required repeatedly due to frequent change in process condition eg. Setpoint.

   • Tune LED blinks at slower rate when Self-tuning is in progress.

   •  At the completion of self-tuning, Tune LED stop blinking.

   • Self-tuning is initiated under the following conditions :

1. When setpoint is altered.

2. When tune mode is altered. (TUNE=ST)

   • ST will start only if PV < 50% of setpoint.
   • ST will work only when ACT=RE.
