Generator controller alarm monitoring

The Be124 is a generator controller alarm monitoring system that provides the following features:

A) - A yellow LED to indicate a warning and a red LED to indicates a shutdown.

B) - Symbols and LEDs, used to indicate Low Fuel / Low Oil Pressure / High Temperature alarm.

C) - A horn output (°) and two alarm repeat outputs.

D) - Descriptive messages of the alarms with date & time.

E) - Event History Memory able to record 500 alarms and events (see section 7.0).

F) - An [ACK] pushbutton to silence the Horn.

(°) The terminal JF-6 drives a horn via a relay. To silence the horn, push the [ACK] pushbutton or wait for the [HORN TIMEOUT] timer to expire (see section 11.7). If the [ HORN TIMEOUT ] is set to [OFF] (in other words, no time-out), the only way to silence the horn is by using the [ACK] pushbutton).

Instructions in case of alarm(s)

  • Look at the front panel and take note of LED indicators and message(s) on the display.
  • Some alarms, in order to cool down the engine, shutdown the engine after a programmable delay. We recommend that you wait the complete stop of the engine has been affected.
  • Push the [ACK] pushbutton to silence the horn. Turn the key to OFF to cancel the alarm.
  • Consult the following sections for further information and remove the cause of the alarm.

Section

 

These could be high severity or critical Alarms. The Be124 generator controller alarm monitoring system opens the Generator Circuit Breaker (GCB) in a way to protect the generator itself.

 

Under voltage / Under frequency may be symptoms of overload. The engine will shut down after a cooling down time.

 

The Be124 generator controller alarm monitoring system provides a shutdown to protect the load and the generator. Check the settings of the parameters and set properly the bypass timing of each alarm.

UNDER  VOLTAGE SHUTDOWN  

The voltage of one or more phases has risen/fallen above or below the pre-set limit.

11.3.1

OVER VOLTAGE  SHUTDOWN

11.3.2

UNDER FREQUENCY SHUTDOWN 

The frequency has risen/fallen above or below  the pre-set limit.

11.3.3

OVER FREQUENCY SHUTDOWN 

11.3.4

OVER KVA  SHUTDOWN

The power has exceeded the pre-set limit.

11.3.9

OVER CURRENT  WARNING    

The current has exceeded the pre-set limit. The Be124 provides a warning and then, if the current rises above certain limit, will open the GCB and shuts down the engine after a cooling down time.
