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 GUIDEUSER 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.

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.
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.

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.
!
!
If auto-tuning is not completed after 3-4 cycles, the auto-
tuning 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.

7. Thermocouple Compensation :
COMP = YES
Configure Yes if compensating cable is connected as
thermocouple extension. Yes should also be configured
in the case if the sensor is directly connected to the
terminal without extension.
COMP = NO
Configure No if non-compensating cable is connected
as thermocouple extension.
