WHAT IS AN AMF CONTROLLER?

An AMF controller governs all functions of a standby generator. It automatically manages the connection assignment of the LOAD to MAINS or GENERATOR. The AMF controller is the core of AMF panels.

THE BEK3 IS A  "ROCK SOLID " AMF CONTROLLER WITH AN ENCLOSURE MADE OF STEEL

We do not use plastic materials for making RELIABLE AMF controllers. The enclosure of the BeK3 controller is made of zinc double-coated steel. Zinc is a heavy element, and when alloyed with other metals provides better corrosion resistance, stability, dimensional strength and impact strength.

THE BEK3 AMF CONTROLLER REAR VIEW

The rear cover made of metal is the best solution for shock-proof equipment. It provides excellent protection against electromagnetic fields by enclosing the 32-bit processor into a Faraday cage. This gives an extraordinary advantage over competitors' plastic-based enclosures.


INGRESS PROTECTION IEC60529 SILICON GASKET UV-PROOF

The BeK3 AMF controller is IP40-compliant. In case you need improved protection, we can separately supply a silicon gasket.

IP65 AMF CONTROLLER

By following our instructions the BeK3 will be IP65-compliant.

AMF WIRING DIAGRAM DESCRIPTION

The BeK3 AMF controller governs the system and transfers the load to the generator or mains smoothly and with short downtime. This AMF panel wiring diagram illustrates the connections of the BeK3 AMF controller. It monitors the parameters of the mains and automatically starts the engine via relays or interface boards. Once the generator provides the correct frequency and voltage, the controller transfers the load from the mains to the generator.

AMF CONTROLLER WIRING DIAGRAM

This happens after a mains failure programmed delay (seconds, minutes or hours). When the engine is cold, the AMF controller provides a warm-up time to run the engine offload. Once the mains has been restored, the AMF controller will connect the load to the mains automatically. After a time delay, the engine is then stopped.

HOW DOES IT WORK IN DETAILS THE AMF CONTROLLER

The BeK3 controller closes the KM-AUX and KG-PILOT contacts to activate the KG (contactor of the generator). In this way, the LOAD is connected to the generator. The KM-AUX are the auxiliary contacts fitted on the body of the utility power contactor (so-called KM). When the KM is open, the KM-AUX contacts enable the KG. The AMF controller activates the KG via the KG-PILOT relay. The N and L3 of the generator supply the coil of the KG. When switching the generator to the mains, the user observes a short ‘power outage’. Normally it is about 2 seconds. This is the typical behaviour of the automatic transfer switch: BREAK-BEFORE-MAKE.


AMF CONTROLLER MAINS-LOAD

The KM contactor connects the LOAD to the MAINS. The coil of the KM energizes using the KG-AUX and KM-PILOT contacts. The KG-AUX auxiliary contacts have a mechanical connection with KG. The contacts close when the KG opens. The KM-PILOT is the utility power control relay. This relay is OFF when the mains is within the settings. In this case, the COIL of the KM is supplied via the N and L3 of the MAINS. By using the normally closed contacts, we are sure to provide priority to the mains in case the AMF controller is damaged or without supply. In case of mains failure, the AMF controller energizes the KM-PILOT. The KM-PILOT contacts will open the KM. Once the KM is open, the auxiliary contacts KM-AUX will close. This is one of the mandatory conditions to close the KG (the KM must be open in the first place).


AMF CONTROLLER DUAL GENERATOR SINGLE LOAD CONFIGURATION

By using this AMF panel wiring diagram, you can connect two generators as an emergency standby to one load. This is not a parallel configuration. It is a basic BREAK-BEFORE-MAKE configuration. In a prolonged power outage, you can set up one generator as a master. In case of failure, the second one will supply the load.

AMF PANEL WIRING DIAGRAM DUAL GENERATOR SETS

On the same principle, you can set up a timer for supplying the load. For example, you can set up 6 hours for each generator. In t


DUAL LOAD WITH A SINGLE GENERATOR

By using this AMF panel wiring diagram, you can connect one generator as an emergency standby to serve both loads. This is not a parallel configuration. The generator will supply the only load that suffers a utility power condition.

Could be only one load or both. The generator will start in case of one utility power failure and stop when the loads can be supplied by the utility power.

THE BEK3 AMF CONTROLLER OUTPUTS

On the removable connector JC you are required to wire the auxiliary relays. The BeK3 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 24 according to your engine battery). The removable connectors JP and JL are provided for the connection of the CURRENT TRANSFORMERS suitable for the current monitoring of the EARTH FAULT and the 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

CANBUS terminals are also provided on this connector (your ECU must be SAE J1939 compliant). The removable plug JG allows you the connect 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 the remote control is activated (Table 9.07 options [25] or [26]). You can stop the engine at any time by selecting the MAN mode.


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.
