Control unit KEA 292 INS

Control unit for isolated operation


The software covers:

  • starting of engine via remote command and start of generator supply,
  • frequency control for island genset operation,
  • genset monitoring and protection,
  • sensing of cooling-down/shutdown of the genset,
  • software for sprinkler mode acc. to VDS 2100-22.

The control unit is fitted with the following facilities for monitoring of the genset:

  • 2-phase for generator monitoring, under- and over voltage, under- and over frequency and asymmetry of phases.
  • 10 externally connected alarm signals,
  • 4 alarms of the generator voltage monitoring, freely programmable to alarms 1 to 10,
  • DC battery voltage monitor.
