The controller is equipped with an adaptive digital filter which is used to filter
out any extraneous pulses on the PV. Filtered PV Value is used for all PV
dependent functions. If PV signal is fluctuating due to noise, increase the filter
time constant value.

This parameter will appear only if selected control mode is ON-OFF.
User can select heating logic in which OP1 will remain ON till PV < SP.
(PV increases when output is ON)
This parameter will appear only if selected control mode is ON-OFF.
User can select cooling logic in which OP1 will remain ON till PV > SP.
(PV decreases when output is ON.)

Function of this parameter is to add/subtract a constant value to the measured
PV to obtain Final PV for control applications. This parameter value needs to be
altered for one of the following reason :
(I) To compensate for known thermal gradient (ii)To match the display values
with another recorder or indicator measuring the same PV.

This parameter value is set according to the type of sensor (Thermocouple or
RTD Input) connected to the Controller's Input Terminals.

Sets the maximum limit for set point adjustment. It can be set from LSPL value
to maximum specified range of selected sensor.
