WHAT IS THE PURPOSE OF GENERATOR CONTROL UNIT?

The main purpose is to add to a generator control panel all features for remote control, protection and monitoring. This is of vital importance when it comes to solar systems. The generating set is always in a remote location. It must be able to start when battery storage is low. The generator control unit will directly send all information via GSM, MODBUS or TCP/IP. For the Be124 generator controller, the above tasks take only 25% of the CPU.

GENERATOR CONTROLLER SUITABLE FOR INDUSTRIAL GENERATOR

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 fully 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.


HOW TO GET THE MOST FROM A GENERATOR CONTROLLER?

A generator controller is a complex piece of technology. It integrates many circuits working at low voltage but also high voltage when it is to generator and utility power monitoring. As a result, we can say that a generator controller monitors the parameters of the Engine (Oil pressure, Temperature, Fuel, Speed, and others), the 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 be 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. Despite the design of a generator controller complies with international standards, a bad layout of your application may deteriorate the reliability of your generator controller. Here there are you why.


WHY A GENERATOR CONTROLLER MUST NOT MONITOR THE UTILITY POWER?

The reason is simple: independently of the "ACCEPTABLE COST" measures that you can take to prevent flashes of lightning or over-voltages from hitting your electronic equipment, you will never be safe enough. IT IS NOT ABOUT INSULATION. The over-voltage transients are coupled to electronic components via capacitors.

NEVER LIKE THIS

AVOID DIRECTLY USING AMF CONTROLLER ON YOUR GENERATOR

do not put AMF controller on the generator

You will never be able to reduce the capacitance to 0 pF; NEVER!  The best choice is always to make an automatic mains failure panel or an automatic transfer switch panel and remotely drive the auto-start remote input of your generator controller.


THIS IS THE WAY TO DO IT

ALWAYS TRUST IN A GOOD AUTO-START CONNECTED TO AN EXTERNAL PANEL VIA INSULATING RELAY

CORRECT WAY TO USE A GENERATOR CONTROLLER

The overvoltages will not affect the power generator or the generator controller. Not having direct cables from utility power, there is no coupling from parasitic capacitors. In the worst case of ATS controller damage, you will be able to start and use the generator.

USING THE Be124

 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 before power down, when you switch on the battery supply, the Be124 generator controller automatically enters the AUTO mode of operation. In other cases, you have to manually start the engine.

Be124 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-minute timeout. To exit the OFF mode turn the key to ‘ON’.

Be124 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-

This 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.

Be124 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.

LOW-BATTERY AUTO-START

You can set up a low battery limit, high battery limit, delays and a time-out. When the controller is in the AUTO mode of operation, the Be124  continuously monitors the battery voltage.  If the voltage drops below the setting for about the time you previously defined, the Be124 will start the engine. Once the battery is supposed to be fully charged, the Be124 will stop the engine. In case the battery will not be able to reach the high battery setpoint, the timeout alarm stops the engine and triggers the battery alarm.

REMOTE START

­­­­­­­­­­­­­­­The Be124 manages multiple sources of remote start. It could be from a programmable input, let's say a hardware start request or a software start request from MODBUS or TCP/IP. You can set delays to start and stop and timeout protection as well.

SCHEDULED START

The Be124 Scheduled Start menu allows you to set the day and time of the week when the automatic start is scheduled to begin. On the same menu, you will set the time to stop the engine. You can make only a scheduled start par day. You can set up a different start-stop cycle every day. The Be124 will repeat the same cycle every week supposing you keep the generator controller in AUTO mode of operation.

Be124 TEST MODE

Turn the key to the ‘ON’ position. 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.
