Digit – Select remote setpoint
0
Remote setpoint by analog input AN2
Control input AN1
1
Setpoint by serial input: process 1 – word modbus 9
process 2 – word modbus 10
P-06
Lower limit setpoint 1 (-999/3000 digit)
P-07
Upper limit setpoint 1 (-999/3000 digit)
Selectable limits of setpoint 1
P-08
Lower limit range AN2 only for V/mA (-999/3000 digit).
P-09
Upper limit range AN2 only for V/mA(-999/3000 digit).
Limits of scale (values to visualize if input AN2 is configured as
V/mA
P-10
Alarms hysteresis (-999/3000 digits).
Hysteresis for alarms tresholds.This function is useful to avoid
disturbing oscillations of outputs
P-11
Configuration alarm no.1 corresponding to output OUT
P-12
Configuration alarm no.2 corresponding to output A1
P-13
Configuration alarm no.3 corresponding to output A2
These parameters allow to select the operating mode for the
relay or SSR outputs when they are not used for process control
(see P-05).
Beside alarm modes described on chap. 30, available options
include also auxiliary functions related to time (steps), to
rising/dwell/cooling gradient or to the state of controller (during
cycle execution or at cycle end).
Setpoint values (comparison values) must be entered on
parameters P-14..16.
