Diesel generator control system outputs connection

Diesel generator control system outputs connection

This removable connector provides you connections for the relays. The output are short circuit proof, but we recommend that you limit the output current to 150mA. The connection of the diodes is a mandatory requirements to comply with international EMC regulations.

Options & description

 

[ 0 ]

The Output is disabled. The Be124 disables the output.

[ 13 ]

Pump to fill the tank. You can connect a relay to drive the Fuel Pump. You can find all details for programming in section 11.6.3-4.

[ 1 ]

Common Speed & Frequency alarms. It energizes in case of Under/Over Frequency or Speed.

[ 14 ]

Prelube. You can connect a pump to prelubricate the engine before starting (see 11.4.1).

[ 2 ]

Common generator alarms. It energizes in case of Under/Over Frequency, Speed and in case of any alarm of the generator (Over Current/ Over/Under Voltage etc..).

[ 15 ]

Auto Mode Status. It informs an external equipment that Be124 is working in Auto mode of operation. You can connect a relay or an external lamp.

[ 3 ]

Common oil pressure alarms. It energizes in case of any alarm related to the engine oil pressure.

[ 16 ]

Idle speed control. You can connect this output (via a relay) to a governor in a way to control the Nominal / Idle speed (see 11.5.4).

[ 4 ]

Common temperature alarms. It energizes in case of any alarm related to the engine temperature (Oil / Coolant / aux. etc.).

[ 17 ]

Maintenance service required. This output energizes when a timer (1-2-3) expires. You have to carry out the maintenence routine (see 10.1).

[ 5 ]

Low / High battery voltage. It energizes in case of battery voltage out of limits: 11.5-15.5 (12 V battery) and 23-31V (24 V battery). To trigger the alarm Be124 needs to detect an abnormal condition for at least 2 minutes.

[ 18 ]

Presence of nominal generator parameters (voltages/frequency/phase rotation etc..). Used to interface other controllers or a PLC.

[ 6 ]

Common fuel alarms. It energizes in case of any fuel level alarm.

[ 19 ]

CANBUS Communication Failure. It energizes in case of communication failure.

[ 7 ]

Fail to start / Fail to stop. It energizes in case of starting failure or stopping failure.

[ 20 ]

ECU Enable 1 (Active when Fuel solenoid and Stop are activated). It could be used to supply the ECU.

[ 8 ]

Common of all warnings. It energizes in case of any warning.

[ 21 ]

ECU enable 2 (Active in MAN, AUTO, TEST modes and during the stop solenoid time). It could be used to supply the ECU.

[ 9 ]

Common of all shutdowns. It energizes in case any shutdown.

[ 22 ]

ECU STOP command. To be used in case the ECU requires a hardware command to stop the engine.

 

[ 10 ]

Common of all warnings and shutdowns. It energizes in case of any warning or shutdown.

[ 23 ]

Stop Solenoid output (see 11.4.7). Used in case you require an energized to stop solenoid.

 

[ 11 ]

Purge (gas engine valve control). You are required to connect a driver relay for the GAS valve. See section 11.4.7 for programming.

 [ 24 ]

Engine Running Status.

 

[ 12 ]

Preglow output. You are required to connect a driver realy for preglow. See section 11.4.5 for programming.

 [ 25 ]

Auto Start. It energize when battery drops under the LOW BATT START setting. It will remain active until engine stops (see 10.4).
