Engineered for versatility, it is the ideal solution for refurbishing second-hand generators or for applications in harsh environmental conditions. The Be24 simplifies the process of transforming any generator into a fully automatic system; by adding three standard automotive relays, you can achieve a complete, reliable auto-start configuration.

Key Features

  • Engine Versatility: Compatible with diesel, gasoline, and gas-driven engines.

  • Flexible Power: Supports both 12V and 24V DC battery systems.

  • Customizable: Features 31 adjustable parameters to tailor the controller to your specific engine and alternator requirements.

  • Rugged Design: Built to endure extreme environments.

Technical Specifications & Monitoring

The Be24 features a high-visibility, military-grade display capable of operating in temperatures ranging from -30°C to +75°C. Whether in intense desert sunlight or extreme cold, the data remains perfectly legible. The front panel buttons are industrial-rated, tested for a lifespan of over one million operations.

Real-Time Monitoring

The display provides continuous, real-time data for:

  • Electrical: Voltage, frequency, and current.

  • Engine: Speed (RPM) and hour count.

  • System: Battery voltage, charger alternator status, and comprehensive alarm monitoring.

Installation and Connectivity

The Be24 is designed for quick and secure installation, featuring a protective plastic cover for the rear connections and all necessary mounting accessories included in the kit.

Inputs & Outputs

  • Connectivity: Uses blade terminals for I/O; logic is positive, short-circuit-proof, and optimized to drive 12V/24V automotive relays.

  • Digital Inputs: Dedicated terminals for Oil Pressure, High Engine Temperature, Emergency Stop, Low Fuel, and Remote Start.

  • Control Outputs: Dedicated outputs for Fuel Solenoid, Stop Solenoid, Start Solenoid, Pre-glow, and Alarm.

  • Speed Sensing: Supports signals from either a magnetic pick-up or a belt-driven alternator (W terminal).

  • Programming: Programming mode is easily enabled via Terminal 2. The unit utilizes removable terminal blocks for easy connection to the alternator and current transformer (CT).

Auto Start Controller Installation Manual

How to Build an Automatic Generator Start System

You can construct a reliable, cost-effective automatic generator start system by connecting just three standard automotive relays to the Be24 Auto Start Controller. This makes the Be24 the ideal solution for refurbishing older diesel-driven generators.

System Protection & Setup:

  • Engine & Alternator Security: By configuring the built-in protections for Over/Under Voltage and Over/Under Frequency, you safeguard both your alternator and the connected load.

  • Sensor Integration: Critical engine conditions—such as low oil pressure, high engine temperature, and low fuel levels—are easily monitored using standard switch inputs.

  • Reliable Connectivity: The integrated blade terminals ensure secure, industrial-grade connections for all wiring.

  • Remote Capability: You can easily enable remote start functionality by configuring the Be24 parameters, allowing for flexible operation tailored to your specific application.

BE24 GENERATOR  CONTROLLER CONNECTIONS

The generator (1) voltage is connected to Be24 via L1 & L3. We recommend that you protect the connections with 1A fuses (4). When you need a Generator Circuit Breaker, use the digital output '2' (but, the output to drive the horn will not be available). If you connect a dashboard, we recommend that you protect the output 15/54 with a 5 Amp fuse.

CLICK FOR HD

Be24-Generator-Key-start-auto-start-wiring-diagram.The outputs of the controller require a pilot relay. The use of fly-back diodes is mandatory. The Be24 detects the rotational speed from a pick-up or the 'W' terminal of the belt alternator. The Be24 automatically calculates the rotational speed from the generator as well. In this case, program the correct number of poles of the alternator. The connections for the engine feature blade terminals 6,3X0,8mm. The generator voltage and current are connected via removable terminal blocks.

USING THE KEY START

You can directly start the engine using the key when you do not require the auto-start function. The rated current of the embedded key switch is about 30 Amps. You can use a 12V or 24V battery. The Be24 auto-start generator module works up to 36VDC. You are required to use cables of appropriate size. We always recommend that you protect the connections by using a fuse. Before turning the key to 'START' wait for the lamp self-test. After that, the Be24 will turn on the fuel solenoid and you can start the engine.

STARTER PILOT RELAY

USING THE AUTO START 

You are required to connect a pilot relay capable of delivering about 30 amps. Do not connect the terminal '50' of the key. You can start and stop the engine using a remote switch connected to terminal '7'. You can adjust start and stop delay timings. The AUTO START module monitors the REMOTE INPUT only if you put the controller in the AUTO MODE using the button on the front panel. You can still use the key start function when the controller is not in AUTO MODE. When you turn the key to start, the BE24 automatically activates the digital output '10' that will excite the pilot start relay.

MODE OF OPERATION OVERVIEW

The Be24 generator auto start module features AUTO, MANUAL, and OFF modes of operation. When you connect the battery supply, the Be24 generator auto-start reacts as follows:

a) if the KEY-SWITCH is in the OFF position, the Be24 auto-start module enters the OFF mode

b) if the KEY-SWITCH is in the ON position, the Be24 auto-start module enters the AUTO mode.

OFF MODE

The OFF mode clears the alarms and turns the Display off. To select the OFF mode, turn the KEY switch off. In the OFF mode, you can read the settings or program the controller.

 AUTO MODE

The Be24 generator auto-start operates according to the parameters indicated in the installation manual. The Be24A initiates the starting when you activate the ‘REMOTE START' input or you set up the SCHEDULER.

To enter the 'AUTO'  mode, use the following instructions:

A) - turn ON the KEY switch; the Be24 generator auto start illuminates the Display and LEDs for 1 second

B) - push the AUTO push button, then the Be24 generator auto start will indicate [uuuu] (Pre-glow cycle) or [StA-]; the yellow Led ‘AUTO’ also illuminates. If the REMOTE START input is not activated, the yellow LED blinks. If activated, the yellow LED illuminates continuously and a start cycle will take place after an adjustable delay time.

C) - To exit the AUTO mode, push the AUTO push button (the yellow LED turns OFF) or turn the KEY switch to OFF.

If an Automatic Periodic Test is triggered (scheduler), the display indicates the message [tESt] (see application note in section 19.0 of the OEM manual).

The Be24A generator auto start stores the AUTO operating mode in the memory; if the battery supply then fails and restores, the Be24A will enter the AUTO mode automatically.

To clear the memory of the AUTO mode, push the AUTO push button, or turn OFF the KEY switch.

MANUAL MODE

The MANUAL mode gives an engine start using the KEY SWITCH. Use the following instructions:

A) - Turn ON the KEY switch; the Be24 generator auto start illuminates the LEDs and Display.

B) - If the display shows the message [uuuu], the Be24 is counting the PRE-GLOW time; wait until the message disappears.

C) - When the display shows the message [StA-] turn the Key to the START position until the engine starts. The Be24 indicates [ . . . .] during cranking.

D) - To stop the engine, turn the KEY switch off.

THE SCHEDULER

To schedule an automatic start, you are required to program the parameters  [P.26] and [P.27] (section 11.0 in the installation manual). To start the engine on a particular window of  time,  follow these instructions:

- disconnect the power supply of the Be24

- wait for the desired start time (external clock reference) and apply the power supply to the Be24.

- select the 'AUTO' mode of operation

Consequently, the Be24A will start the engine after the programmed number of days. The engine will run for the programmed time. If the battery voltage is removed, we recommend that you synchronize the ‘Power On’ of the Be24A with an external clock.

Time remaining to start indication:

The Be24 shows the remaining time to trigger the test: push the [ENTER] pushbutton while Be24 is in the AUTO mode of operation. As a result, the display will indicate days followed by hours ([DD.hh]).
