GENERATOR CONTROLLER

BE124 CENTURION COMBINED AUTO START & KEY START MODULE

Generator Controller  Be124 Centurion

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 is 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 wods, 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 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. For standard applications we recommend that you use the BE24 Auto Start Module or Be172 Key Start module.

CONNECTIONS  TUTORIAL

 

Generator Controller Connections
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 ON/OFF coil [6].

 

  In case of troubles 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 manual operated generator. The best recommended option is to use the JF-7 (start-output) that will allow you a safe MANUAL and AUTOMATIC operation.

 

  As long as you need a 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 TERMINOLOGY
Finally, just for your knowledge, a brief explanation of the terms commonly used in a typical Generator Controller application.

 

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).
An 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 analogue sensors or switches for the OIL/°C/FUEL/Auxiliary Temperauture 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.

HOW TO USE 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 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 shutdown automatically after a 30 minutes timeout.
To exit the OFF mode turn the key to ‘ON’.

 

MANUAL MODE

 

Turn the key to ‘ON’ position. After the automatic 5 second self-check turn the key to ‘START’ position until 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 anytime to open the ‘Be124 Status’ page. Push the [GCB] pushbutton to open the generator circuit breaker. To stop the engine, turn the key to ‘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 ‘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 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 ‘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 ‘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.

USING THE GENERATOR CONTROLLER

EMBEDDED OSCILLOSCOPE

Push [ACK]; the Be124 generator controller displays  the ‘Controller Status’ page. Push [←] to open the Main Menu. The [ENGINE METERING] menu will appear on the top of the display. Repeatedly push [ ↓ ] to select [oscilloscope]. Push [→] to activate the oscilloscope.
The oscilloscope embedded into Be124 generator controller is able to analyze the waveform of the voltages and currents. True RMS voltages, currents and frequency measurements are  indicated on the top of the display also.
The BE124 generator controller, by means of software, provides automatic setup in a way to optimize the display of the waveform (auto trigger, auto range etc.).
In case you want to see details about the peaks of the waveforms, you can use the buttons [ ↓ ][ ↑ ] to display the positive peaks or negative peaks (POS= positive and NEG=negative). The Be124 will optimize the resolution automatically.
When you start the oscilloscope, internal setting is 'AUTO' (both positive and negative on the same screen). But you can change the display mode at anytime. On the left side you see examples of display for voltage VL1 to Neutral.
Note: over a frequency of about 150 Hz the LCD changes the presentation of the waveform. In this way, the measurements  displayed will allow you to better analyze the stability of the parameters.
