Pump alarms
The module provides a failed to command alarm output. The status is monitored and a fail-to-command alarm is generated:
Pump command |
Status input |
Fail to command alarm selected |
Pump on |
off |
Pump fail to command alarm |
Pump off |
on |
Pump fail to command alarm |
Alarm input
The alarm input Alarm will generate a point alarm.
Manual or automatic reset of alarms
In case of an active alarm, manual or automatic reset of alarms can be selected, depending on the setting of parameter ALM-03.
Note: When an automatic reset function was selected in the parameter list (ALM-02 = 1), the related output PmpCmd will stay on.
Common alarm output
The output CommAlarm will be in alarm whenever the pump on-/ off- or fail to command alarms or alarm inputs is in alarm.
Alarm Reset
The alarm reset happens on the positive edge of the Reset signal.
A reset will be done even if the pump enable input is still on.
We recommend to solve the alarm root cause before activating a reset signal, other wise the alarm will occur again.
