No alarm in case of generator failure

Hello everyone,

During a routine test run of a diesel generator via Cerbo GX in an off-grid system with Mp2, the diesel generator failed. The reason why the diesel generator simply stopped is still being investigated.

The Cerbo GX controls the conventional diesel generator via 2 ON and OFF relays without further communication. It started up, but then stopped…

Strangely, there was no alarm message on the Cerbo or VRM portal.

Any tips or anything I might have overlooked?

Thanks for your help.

The following is programmed:

  • Warm & cold running phases
  • Autostart when SOC falls below a certain level
  • Detect generator at AC input = ON
  • Alarm if generator is not in autostart mode = Off
  • Stop generator when AC input is available = Deactivated
  • Skip execution: always start
  • Periodic maintenance run
