Pump operation alarms
One can set threshold alarms on the following daily measurements:
- Maximum number of pump starts in the last 24 hours
- Maximum total pump operation time in the last 24 hours
An alarm can also be set for the cumulative pump motor run time to alert that some form
of maintenance is now due.
HMI: Settings / Pump
When installing in a retrofit situation, the initial value for the pump/compressor run time
can be entered:

The various alarms can be seen in the HMI:

Pump motor current
Using a CT, the CBW3 is able to measure the initial inrush current used by the
compressor/pump motor(s) in order to notice any changes.
A graph of the first 12 seconds of the "pump motor current /vs/ time" curve is displayed
in the HMI. It is used to visualise the peak inrush current at startup:
