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.
