Program List and Explanations
68
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

Alarm High:
If the measured value rises above the alarm high value,
the alarm relay is activated and E001, is displayed in the message
list.
Range: 0.000 –3000
S
5.3.1.1.1.25
Alarm Low:
If the measured value falls below the alarm low value,
the alarm relay is activated and E002 is displayed in the message
list.
Range: 0.000 –3000
S
5.3.1.1.1.35
Hysteresis:
Within the hyst. range, the relay does not switch. This
prevents damage of relays contacts when the measured value fluctu
-
ates around the alarm value.
Range. 0.000 –3000
