OUTPUT2
FUNCTION
This parameter allows the User to select output 2 as an ‘Auxiliary’ control.
For options refer Table 3.
This parameter allows the User to select output 2 as an ‘Alarm’ control.
For options refer Table 4.

User can set the desired RAMP rate in USER list.
The RATE parameter will not be prompted in USER list.
Overshoot
Control
point
50%
This parameter will be prompted only if selected control action is PID. Setting this
parameter on higher side will proportionally slows down the rate of rise of PV to
minimize overshoot (this may cause delay to reach SP). Disabling or Setting this
parameter on lower side will proportionally increase the rate of rise of PV ( which
may cause overshoot). Disable this option if delay is not required to reach SP.
(This may cause overshoot w.r.t. SP)
CONTROL
LOGIC
FOR OP1
HEAT
This parameter will be prompted 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.)

T.P
User can select between ON-OFF or T.P action algorithm to be adopted for output.
INPUT
FILTER
0.5 C
o
The controller is equipped with an adaptive digital filter which is used to filter out any
extraneous pulses on the PV. The filtered PV Value is used for all PV dependent
functions. If the PV signal is fluctuating due to noise, increase the filter time
constant value.
PROCESS

0 C
o
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 can be altered :
(i) To compensate for known thermal gradient.
(ii)To match the display values with another recorder or indicator measuring the
same PV.

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