
Command Delay
Command delay (only in ON / OFF functioning). (In case of valves it works
also in P.I.D. and represents delay between opening and closure of two
contacts).
-600…+600 seconds (tenth of second in case of servo valve).
Negative: delay when turning off .
Positive: delay when turning on.
Default : 0.

Command Setpoint Protection
Allows/prevents changes to command setpoint value by keyboard.

Modifi cation allowed ( Default )


Tune
Autotuning type selection.

Disabled ( Default )

Automatic (P.I.D. parameters calculation at each activation and /
or each change)

Manual (launch by keyboards or by digital input)

Once (P.I.D. parameters calculation only at fi rst start)

Setpoint Deviation Tune
Selects deviation from command setpoint as threshold used by
autotuning to calculate P.I.D. parameters.
