WHAT IS A GENERATOR CONTROLLER?

A generator controller integrates, in one electronic module, an Engine Control unit, a Charging Alternator Monitoring Module, and programmable relays committed to protecting all systems of the diesel power generator.

THE BE124 CENTURION COMBINED AUTO START & KEY START MODULE

The Be124 is the most powerful generator controller on the market. It features extremely high accurate measurements for Vac - Aac - Hz - PF - Vac - Vdc - RPM - kW - kVA - kVAr - kWh - PF- BAR - PSI - °C - °F. Despite its basic accuracy being 1,5%, you can get higher precision by using the embedded autocalibration software. You can use the Be124 for industrial diesel-driven heavy machinery. This generator controller works up to 600Hz. In other words, it is a suitable choice for aircraft ground support equipment generators. You can connect the Be124 to TCP-IP or GSM systems. The Be124 generator controller is the appropriate solution when you have to refurbish the GAS-GASOLINE-DIESEL generator. In effect, it can monitor generators up to 1000kVA. In addition to standard configurable input & output, the Be124 complies with SAEJ1939 via a fully isolated CANbus interface. In conclusion, the BE124 is the best option as long as you have to control an high valuable generator.

Generator Controller Wiring Diagram

The generator is connected to the input voltage sensing circuit via fuses (5). The Current Transformers (2) must be provided to protect the generator from overload problems. We recommend that you connect also a current transformer able to measure a current fault (4). The circuit breaker should be operated via an ON/OFF coil [6]. In case of trouble, the Be124 protection relay will disable the circuit breaker protecting LOAD and Generator. Removable connector JF allows you to connect all output relays with pre-configured or user-programmable options. The front panel features a Key switch (10). It can be mainly used to start the engine with a manually operated generator. The best-recommended option is to use the JF-7 (start-output) which will allow you a safe MANUAL and AUTOMATIC operation. As long as you need remote monitoring using a computer, the Be124 coupled with its RS485 port supports the MODBUS-RTU protocol. In case your engine is controlled by an ECU (SAE J1939), the Be124 provides the CANbus isolated port. You can connect any SAE-J1939 compatible engine. To summarize, the Be124 Centurion features a full configurable PICKUP input. It will be able to provide rotational speed information and a proper crank setting. As a result, you will have at your disposal a powerful monitoring tool.

GENERATOR  CONTROLLER DESCRIPTION

A generator controller integrates, in one electronic module, an Engine Control & Protection unit, a Charging Alternator Monitoring Module, and a special programmable relay for the protection & monitoring of the Alternator. As a result, we can say that a generator controller monitors the parameters of the Engine (Oil pressure, Temperature, Fuel, Speed, and others), Charger Alternator, and the main Alternator. First of all, it compares the settings of the alarms stored in the memory with the measurements made on the input circuits. The second important task is using the result of these comparisons to generate alarms, protecting actions, warnings, or logic functions (it activates a particular output for example).

A high-tech generator controller must feature a range of programmable settings and is engineered to comply with international standards like NFPA110 CSA. If the CANBUS is not available a good Generator controller should be capable of interfacing with analog sensors or switches for the OIL/°C/FUEL/Auxiliary Temperature monitoring. Equally important, for a generator controller, is the ability to operate reliably in a range of environments, from minus 25 up to 70 degrees Celsius.

USING THE GENERATOR CONTROLLER

 The mode of operation of Be124 is selected via a key switch and a [AUTO] push button. If the Be124 generator controller was in TEST or AUTO mode prior to power down, when you switch on the battery supply, the Be124 generator controller automatically enters the AUTO mode of operation. In the other cases, you have to manually start the engine.

OFF MODE

Turn the key to ‘OFF’: you switch OFF the Be124 and clear the fault alarms.

You are allowed to program the parameters or modify the settings. The backlight of the display will shut down automatically after a 30 minutes timeout. To exit the OFF mode turn the key to ‘ON’.

MANUAL MODE

Turn the key to the ‘ON’ position. After the automatic 5 second self-check turn the key to the ‘START’ position until the engine starts. The display will automatically show the ‘Be124 Status’ page. During cranking, depending on the efficiency of the battery, the generator controller may turn off the backlight of the display. Wait until the green LED GCB-ON starts blinking: it means that the generator is working within the settings. Push the [GCB] push button to close the generator circuit breaker: the green LED [GCB] will light and remain lit. Use the arrow buttons to browse the instrumentation. Push [ACK] at any time to open the ‘Be124 Status’ page. Push the [GCB] pushbutton to open the generator circuit breaker. To stop the engine, turn the key to the ‘OFF’ position; the messages [MODE OFF] & [STOPPING] will appear on the display for the programmed 'Stop Solenoid' time.

After a complete stop, you can restart the engine.

AUTO MODE

­­­­­­­­­­­­­­­Turn the key to the ‘ON’ position. Push the [AUTO] push button until the yellow LED [AUTO] illuminates. The engine starts when the generator controller detects a request to start from a configurable input. The green LED GCB blinks when the generator is working within the programmed limits. After the [WARM UP] time, the generator circuit breaker (GCB) will close automatically. Use the arrows to browse the instrumentation. Push [ACK] at any time to display the ‘Be124 Status’ page. When there is a request to stop the engine, the generator controller opens the GCB and triggers the [COOL DOWN] time. After that, the Be124 will stop the engine.

In the auto mode of operation, the generator controller will periodically test the engine if the scheduler is correctly programmed. During the test, the yellow LED [AUTO] will continue to blink; the display indicates the message  [TEST]. To stop the engine, turn the key to the ‘OFF’ position at any time. The display continuously informs you about what Be124 is doing. The engine will start when you program the AUTO START function as well.

TEST MODE

Turn the key to the ‘ON’ position. Push and hold the [AUTO] push button for at least 10 seconds until the display indicates the message [TEST MODE] and the yellow LED AUTO starts blinking. The generator controller will start the engine immediately. The generator controller will enable the generator circuit breaker (GCB) only if not otherwise programmed by the parameter [GCB TEST CONTROL]. To exit the ‘TEST’ mode, push the [AUTO] push button: the generator controller will enter the ‘MAN’ mode of operation.
