Reset time:
The reset time is the time till the step response of a sin
-
gle I-controller will reach the same value as it will be suddenly
reached by a P-controller.
Range: 0–9’000 sec
5.2.1.43.4
Derivative time:
The derivative time is the time till the ramp re
-
sponse of a single P-controller will reach the same value as it will
be suddenly reached by a D-controller.
Range: 0–9’000 sec
5.2.1.43.5
Control timeout:
If a controller action (dosing intensity) is constantly
over 90% during a defined period of time and the process value
does not come closer to the setpoint, the dosing process will be
stopped for safety reasons.
Range: 0–720 min
5.3 Relay Contacts
5.3.1
Alarm Relay:
The alarm relay is used as cumulative error indicator.
Under normal operating conditions the contact is active.
The contact is
inactive at:
Power loss
Detection of system faults like defective sensors or electronic
parts
High case temperature
Process values out of programmed ranges.
Program alarm levels, hysteresis values and delay times for the fol
