MIN: minimum power (stored in memory) supplied by the PMM module in kW since the last reset.

MAX: maximum power (stored in memory) supplied by the PMM module in kW since the last reset. The minimum, maximum and average power values are reset via the communication function.

The SELECT button may be used to hold the display of a measurement if the module is set up for autoscrolling (parameter rotation). The display flashes and the measurement is not updated.

3.4 Alarms

Access alarm mode by pressing simultaneously the SELECT + METER buttons.

This mode displays the list of stored major and minor faults that have occurred in the PMM or on the output circuits. When an alarm is present in the memory, LED 17 goes on:

◗yellow for fault that does not hinder normal operation; ◗red for a fault requiring intervention.

Ph-B: alarm on phase B.

CH-25: alarm on output circuit 25.

Ph-B CH25

 

Alarm text:

WARNING

 

 

 

 

WARNING: indicates that the current on the indicated circuit (number 25, phase B) is between 60 and 80% of the maximum value.

ALARM: indicates that the current on the indicated circuit is higher than 80% of the maximum value.

OVER VOLTAGE: the voltage supplied by the PMM exceeds the permissible range by over 10%.

OVER CURRENT: there is an overload on the PMM.

AUX INPUT ALARM: this alarm signals either:

◗excessive temperature rise in the isolation transformer,

◗or activation of the remote shutdown button.

These alarms are stored in memory:

◗Press the

SELECT

button to clear the displayed alarm.

◗Press the

METER

button to return to metering mode.

The display automatically returns to metering mode if buttons 19 to 22 are not used for ten seconds.
