Command
Delay
Command delay (only in
ON/OFF functioning).
(In case of servo valve it
also functions in PID and
represents the delay
between the opening and
closure of the two
contacts)
-180…+180 seconds (tenths of
second in case of servo valve).
Negative: delay in switching off
phase.
Positive: delay in activation phase.
Default: 0.

Proportional
Band
Proportional band
Process inertia in units
(E.g.: if temperature is in
°C)
0 on/off if
equal to 0. Default
1-9999 digit* (degrees if
temperature)

Integral Time
Integral time. Process
inertia in seconds
0.0-999.9 seconds (0 integral
disabled)
Default: 0.
20
Derivative
Time
Derivative time. Normally
¼ the integral time
0.0-999.9 seconds (0 derivative
disabled)
Default: 0.
21
Cycle Time
Cycle time (for PID on
remote control switch
10/15sec, for PID on
SSR 1 sec) or servo time
(value declared by servo-
motor manufacturer)
0.1-300.0 seconds
Default: 10.0.
For motorised valve minimum time
in 1.0.
