BERNINI DESIGN LAUNCHES THE FIRST OPAMP-LESS AMF PANEL

THE BeK3-ZERO FEATURES AMF+ATS+GENERATOR CONTROLLER

INSTALLATION MANUAL

The Automatic Mains Failure controller BeK3-Zero is a 3-phase AMF/ATS module that includes a generator & engine controller. It interfaces with standard engines if analogue sensors or digital sensors are available.


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.  The BeK3 complies with NFPA-110 / NFPA-99 specifications. The proprietary OPAMP-LESS solution makes the BeK3-ZERO the most competitive player in the AMF world. When you need additional features like ModBus, CanBus and TCP/IP you may consider the BeK3-PLUS controller.

THE ENCLOSURE MADE OF STEEL

The enclosure is made of zinc double-coated steel. Zinc is a heavy element, and when alloyed with other metals it provides better corrosion resistance, stability, dimensional strength and impact strength. 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 makes an extraordinary advantage over competitors' plastic-based enclosures.

INGRESS PROTECTION IEC60529

The BeK3-Zero is IP40-compliant. In case you need an improved protection, we can separately supply a silicon gasket. By following our instructions the BeK3-Zero will be IP65-compliant.

AMF PANEL WIRING DIAGRAM DESCRIPTION

The BeK3-ZERO 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-ZERO AMF controller. It monitors the parameters of the mains automatically start the engine via relays or interface board. Once the generator provides the correct frequency and voltage, the controller transfers the load from the mains to the generator. 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.

AMF PANEL WIRING DIAGRAM

HOW IT WORKS IN DETAILS

The generator is electrically connected to the LOAD via the KG (contactor of the generator). This is possible only when both contacts, KM-AUX and KG-PILOT are closed.

The KM-AUX are the auxiliary contacts fitted on the body of the Mains 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 coil of the KG is supplied by the N and L3 of the generator.

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.

MAINS-LOAD

The mains is connected to the LOAD via the KM contactor. The coil of the KM is energized via the closed contacts KG-AUX and KM-PILOT.

The KG-AUX are the auxiliary contacts mechanically fitted on the body of the KG. Being the contactor of the generator open, the auxiliary contacts are closed. 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).

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 case of a prolonged utility 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 this way, you can equalize the working like of the two generators.

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.
