Maintenance Indicators

General Description

The BSCM module has 7 counters that help managing the ComPact NSX circuit breaker.

The BSCM 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.

  • A threshold is associated to the OF counter and to the close circuit breaker command counter.

    The user can set the threshold to any value from 0 to 65534. The factory setting is 5000. An alarm is generated when a counter reaches the threshold.
