You can observe the GENERATOR  connected to the LOAD via the CURRENT TRANSFORMER  and the GENERATOR CIRCUIT BREAKER .The coil of the circuit breaker is driven by the GCB relay . In order to protect the cables we recommend that you use fuses of proper size . You can connect driver relays  to the output blade terminals.You can use 12 or 24V battery . The Be24 detects speed via a pick-up . Be24 accepts digital signals . You are required to provide relays for starter and auxiliary equipment if required . The Be24 accepts belt alternator  with D+ or / and 'W'. Relays must be provided for FUEL SOLENOID , AUDIBLE SIGNAL and START connected to terminal #10. You can start directly the engine with the key switch or use a pilot relay for automatic use . By simplifying this diesel generator control panel wiring diagram you can make a cost effective key start module. You are required to connect the terminal '50' of the Be24 controller directly to the 30AMP-rated start pilot fitted on the crank-motor.

Be124 diesel generator control panel wiring diagram
In this diesel generator control panel wiring diagram you can see the details on how to make a generator control panel using the Be124 generator controller.
You can observe the GENERATOR  connected to the LOAD via the CURRENT TRANSFORMERS  and the GENERATOR CIRCUIT BREAKER .The coil of the circuit breaker is driven by the GCB relay . The BE124 can monitor the EARTH FAULT CURRENT via a current transformer . In order to protect the cables we recommend that you use fuses of proper size . You can connect driver relays  to the JF removable plug.  and  allow you to connect ECU and ancillary computer equipment. You can use 12 or 24 V battery . The Be124 detects speed via a pick-up . Be124 accepts analog & digital signals  & . You are required to provide relays for starter and auxiliary equipment if required . The Be124 accepts belt alternator  with D+ or / and 'W'. By following the Be124 diesel generator control panel wiring diagram you can make a state-of-art auto start by using to inexpensive automotive relays.
In this diesel generator control panel wiring diagram you can see the details on how to make a generator control panel using the BeK3 generator controller. This is a general wiring diagram, it indicates all features of a state-of-art AMF ATS control panels. You can reduce the number of components according to your needs.
An interesting feature is the possibility to connect the current transformers on the LOAD side. In this way you can get the current measurements when load is connected to the power utility. Please note that the over current alarm (WARNING or SHUTDOWN) are active only when the LOAD is connected to the generator. This avoids alarms when the load is normally connected to MAINS. The display clearly indicates if it is about Generator Current or Power Utility Current.
Engine connections of a generator control panel fitted with BeK3 AMF controller
The Bek3 AMF panel interfaces with automotive relays. This is the best option: in case of failure you can find an automotive plug-in realy in a shop in your street. You are required to use 90-200 OHM dc coil relays (12 V or 24V, according to your engine battery). In case of troubles, you are not required to change the controller! The Bek3 provides over voltage protection and all outputs are short circuit proof. This will add more reliability to your installation.
A BEK3 AMF panel can interface with ANALOGUE and DIGITAL sensor fitted on the engine as indicated in this diesel generator control panel wiring diagram. In other words you can use any kind on diesel engine on the market.
Terminals for RS485 serial interface are provided in case you need to control and monitor the panel by remote. Software is provided free of charge. You have a wide choice of accessories for MODBUS, GSM or TCP-IP monitoring. When your diesel generator is driven by an SAE J1939 compatible engine, we recommend that you connect the CANBUS port. In this case sensors are no longer necessary.The BeK3 features 3 fully adjustable outputs. You can choose, for each output, one of the 80 available options. You can adapt the panel to any state-of-art factory automation system.
