Program List and Explanations
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-
lowing parameters:
Cond.1 (sc)
Cond.2 (cc)
pH
Ammonia
Sample Temp. 1
Sample Temp. 2
Case Temperature low
5.3.1.1 Conductivity
5.3.1.1.1 Cond. 1 (sc)
5.3.1.1.1.1 Alarm High: If the measured value rises above the alarm high val-
ue, the alarm relay is activated and E001, is displayed in the mes-
sage 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 fluc-
tuates around the alarm value.
Range. 0.000–3000 S
5.3.1.1.1.45 Delay: Duration, the activation of the alarm relay is retarded after
the measuring value has risen above/fallen below the programmed
alarm.
Range: 0–28‘800 Sec
