BEK3-PLUS AUTOMATIC MAINS FAILURE CONTROLLER

IP65

CANbus & MODbus

The Automatic Mains Failure controller BeK3.PLUS is a 3-phase module that includes a generator & engine controller. It connects, via CANbus, engines with ECU (SAE-J1939). It also works with standard engines if analog sensors or digital sensors are available. It is enclosed in a standard DIN 192x144mm case made of steel. A silicon gasket features an ingress protection IP65.

AUTOMATIC MAINS FAILURE CONTROLLER VIDEO TUTORIAL

All parameters, alarms, and operating functions are indicated by means of a 128X64 graphic display capable of operating in a temperature range between -25°C and +70°C.  Measurements including Vac, Aac, Vdc, kVA, kVar, kW, Energy, Pf, Hz, hour count, R.p.m., Oil Pressure, Engine Temperature, Battery Vdc (Engine), and Fuel Level.  A monitoring and control software program is provided free of charge. The BeK3 provides MODBUS via RS485 and complies with NFPA-110 / NFPA-99 specifications. The optional module TCP-IP Server will allow you TCP-IP connection to INTERNET via a ROUTER. By using the Be16 module you can control the AMF Controller BEK3-PLUS from a remote location by using short messages (SMS) via a GSM modem. You can download applications for your mobile phone for quick use of the messages. You can use also our RS485-USB converter to connect a computer as far as 1000 meters away.

BEK3-PLUS OUTPUT RELAYS

On the removable connector JC you are required to wire the auxiliary relays. The BeK3-PLUS provides a common supply rail (JC8). It is about a dc supply suitable for automotive relays that includes over-voltage protection, short circuit protection, and EMI protection. You are required to use 90-200 OHM dc coil relays (12 V or 24V according to your engine battery). The removable connectors JP and JL are provided for the connection of the CURRENT TRANSFORMERS suitable for current monitoring of the EARTH FAULT and current monitoring of the 3-PHASE GENERATOR. A /5 transformers are required in the range of 50 up to 9900 Amps.

MAINS & GENERATOR CONNECTIONS

The JA removable plug is used to connect the Mains & Generator voltages. Electrical parameters must be in the range of 80-600V and 20-99HZ. The version BeK3-400Hz is normally available on request for Aircraft Ground Support Equipment. Protection fuses are highly recommended for cable protection. The connector JF is used for the ANALOG and DIGITAL sensor fitted on the engine.

CANBUS & MODBUS CONNECTIONS

Terminals for CANBUS are provided on this connector also (your ECU must be SAE J1939 compliant). The removable plug JG allows you the connection of the RS485 serial interface. The internal driver will allow you to use a 1000 m cable length.

AUTO MODE OF OPERATION

The AMF controller BeK3-PLUS can start the engine at any time. Do not work on equipment, which is controlled by the BeK3-PLUS. When servicing the engine, disconnect the battery and battery charger. We recommend that warning signs be placed on equipment indicating the above.

­­­­­­­­­­­­­­­­­­

  Push the [AUTO] push button until the yellow LED illuminates. The engine starts when the BeK3-PLUS detects a Mains failure (see section 9.01 for settings). The circuit breaker of the Mains opens after the [MAINS BREAKER] timing. After the  [WARM UP]  time if the voltage and frequency are within the settings, the circuit breaker of the Generator will close. If the Mains restores, the KG will open. The KM will close following a programmed  [KM CHANGEOVER]  timing. The engine will stop after a  [ COOL DOWN ]  time. If the engine shuts down, because of an alarm, the KM closes independently of the Mains status if the  [ NFPA-110 ]  is on, otherwise, the KM will close only if the parameters of the Mains are within the programmed settings. In AUTO mode, the BeK3 will periodically test the engine if the periodic test is correctly programmed. During the test, the yellow LED of the AUTO mode will continue to blink. In AUTO mode, the BeK3-PLUS can start and stop the engine if remote control is activated (Table 9.07 options [25] or [26]). You can stop the engine at any time by selecting the MAN mode.


REMOTE MONITORING 

  The BeK3-PLUS automatic mains failure controller features an RS485 serial interface capable of supporting Modbus RTU. By using appropriate options we can offer GSM remote monitoring TCP-IP remote monitoring, and Modbus remote monitoring.


TEST MODE

  Push and hold the [ AUTO ] push button until the yellow LED starts to blink. The BeK3-PLUS will start the engine and transfer the load to the Generator only in case of Mains failure if not otherwise programmed by the parameter [ KG TEST CONTROL ] (section 8.03). To exit the TEST mode, push the [ AUTO ] push button shortly or select another mode of operation.
