Maintenance Indicators
General Description
The BSCM Modbus SL/ULP module has seven counters that help to manage the ComPacT NSX circuit breaker.
The BSCM Modbus SL/ULP module counters have the following properties:
-
All the counters are saved in non-volatile memory to prevent data loss in case of power loss.
-
The cumulating OF counter is read only. It stops incrementing when it reaches the maximum value 4 294 967 295.
-
The user can preset all counters (except the cumulating OF counter) to any value from 0 to 65535. The counters stop incrementing when they reach the maximum value 65535.
-
The OF counter and close circuit breaker command counter have a threshold which can be set by the user, to any value from 0 to 65534.
The factory setting is 5000. An alarm is generated when a counter reaches the threshold.
