PARAMETERIZATION
Parameter Value range Factory setting Meaning
Controller structure 1 P, I, PD, PI, PID PID Only PI and PID can be implemented on modulating
controllers.
Proportional band 0 - 9999 Digit 0 Digit Size of the proportional band
Proportional band = 0 means that the controller structure is
ineffective! (limit comparator response)
In the case of proportional controllers, the proportional band
must be > 0.
Derivative time 0 - 9999 sec 80 sec Determines the derivative component of the controller output
signal.
Reset time 0 - 9999 sec 350 sec Determines the integral component of the contoller output
signal.
Cycle time 0 - 9999 sec 20 sec When using a switched output, the cycle time should be
chosen so that a) the pulsed energy flow to the process does
not cause any intermissible fluctuations of the process value
and b) the switching elements are not overloaded.
Contact spacing 0 - 999 Digit 0 Digit The spacing between the two control contacts for 2-setpoints
or modulating controllers, or proportional controllers with an
integrated actuator driver.
Switching differential 0 - 999 Digit 1 Digit Hysteresis for switching controllers with proportional band = 0
Actuator time 5 ... 3000 sec 60 sec The actually utilized operating time of the regulating valve for
modulating controllers or proportional controllers with an
integrated actuator driver.
Working point - 100 ... + 100 % 0 % Output level for P and PD controllers
(when x = then y = Y0)
Output level limiting 0 ... 100 % 100 % The maximum limit for the output level.
- 100 ... + 100 % - 100 % The minimum limit for the output level.
Minimum relay ON
time
0 ... 60 sec 0 sec Limits the frequency of switching for switched outputs.
Parameter sets
General
Two parameters sets can be stored for each controller channel.
Access code
Factory-set code: 0001
The access code can be modified via the setup program.
