Customisable alarms
Customisable alarms make it possible to monitor any measuring event detected by
the Energy trip unit.
It is possible to define up to 12 alarms for a single trip unit. Each alarm is dedicated
to monitoring a single measurement.
A custom alarm is defined through the following parameters:
- Measurement monitored
- Activation threshold
- Deactivation threshold
- Activation time delay
- Deactivation time delay
- Priority level
Activation condition for customisable alarms
Activation of a custom alarm results from one of the following conditions:
- Positive breach of a threshold
- Negative breach of a threshold
- Equal to a measurement value
Activation by positive breach
In the case of a positive breach of a threshold, activation of the alarm is dependent
on the activation threshold being positively breached.
