AMF PANEL GSM REMOTE CONTROL MONITORING

These AMF, automatic mains failure, panels feature the BeK3 AMF controller. The BeK3-based AMF panel is the correct choice for critical applications like hospitals and telecom shelters. This page is an overview of our products and useful information.

Bernini Design started designing AMF panels in 1994. With over 30 years of experience, we manufactured over 23,000 automatic mains failure panels.

WHAT ARE THE RATINGS FOR AMF PANELS?

From a minimum of 15KVA up to 1000KVA. Typical voltage ratings for automatic transfer switch panels are 440V tri-phase with or without neutral. When purchasing an automatic mains failure panel, consider a safety margin of 20% by choosing which has the biggest power: utility power or generator.


CONTACTORS-BASED CHANGEOVER

READ MORE ABOUT BEK3  AMF CONTROLLER

Using two contactors with mechanical interlocks will achieve precise control monitoring and protection of your emergency generator. The BeK3 features earth fault monitoring to detect troubles in critical applications.

ATS PANELS WITH CONTACTORS CHANGEOVER

The contactors, usually four-pole, are coil-operated switches that close a circuit when the excitation coil is supplied with alternating 230V.

THE ADVANTAGES OF THE MANUAL OVERRIDE CONTROL

The AMF controller features fully MANUAL, AUTOMATIC, REMOTE and TEST modes of operation. But in extreme cases, you can activate the EMERGENCY LEVER. This switch overrides any electronic control and directly connects the generator or the mains to your building.

MANUAL SWITCH OVERRIDE


THE AMF PANEL CONNECTIONS

The BeK3 AMF panel features short-circuit-proof relay outputs for fuel solenoid, start solenoid and stop solenoid. Two additional relays can be used for user-defined particular functions. The first step is to connect the input-output terminals to the engine. Each output is rated at 4 amps. Use a pilot relays to drive the starter motor and fuel solenoid. The input-output lines are configured by default. But you can change the configuration according to your needs.

ENGINE INPUT-OUTPUT TERMINALS

connect the input output lines to the engine

You can now connect the CANBUS to the ECU and MODBUS if a monitoring system works on an RS485 serial interface. We offer software for control and monitoring free of charge.

CANbus and MODbus CONNECTIONS

connect the CANBUS to the J1939 compatible ECU. Connect the RS485

If your engine features an analog sensor you must connect the terminals 30, 31 and 32. Terminal 33 is required to improve the precision of the measurements. It must be connected to the body of the engine.

ENGINE SENSOR CONNECTIONS

connect he analog sensot of the engine

After you have carried out a complete test of the engine, you can connect the alternator. Follow the international standard for safety. Use cables of suitable size. The BeK3 can monitor a fault current to earth, but you must connect a current transformer to terminals 34 and 35.

ALTERNATOR CONNECTION

connect the generator

After a complete test of the generator, you can connect your load. You will test the generator on load conditions. You are required to set all protections about voltage, frequency, and overcurrent.

LOAD CONNECTION

connect the load to the AMF panel

The final job consists of connecting the Mains. After that, you can complete a test of your standby generator. You must set up all settings for mains failure that match the requirement of your load. Install a circuit breaker, on the transformer output, capable of opening the circuit in case of a direct short circuit.

UTILITY POWER CONNECTION

connect the mains to the panel

HOW DOES AN AMF PANEL WORK?

REDUNDANT MUTUAL DUAL-GENERATOR CONFIGURATION AMF PANEL

Regarding special applications, the AMF controller reveals its special character. The adjustable settings of the BeK3 can easily manage a dual-generator configuration.

REDUNDANT DUAL-GENERATOR CONFIGURATION AMF PANEL

The panel, despite the complexity of the automation, is simple. The two BeK3 controllers work together. The final goal is to rely on two generators in case of a prolonged utility power failure. In case of trouble on one generator, the other one will automatically start.

MUTUAL DUAL GENERATOR AMF CONTROL PANEL

You can also limit the run time of a generator. The other generator will start for a programmable time. The cycle repeats itself until the utility power is restored.


NO MORE HEADACHE IN COMMUNICATIONS WITH PLUGS AND CONNECTOR

WELCOME TO THE WIRELESS AGE

We started in 2012 to design electronic boards with fewer connections. Our panel require only 25 % of cables compared with a standard AMF panel. Why? The answer is simple: Bernini Design has its design centre for electronic equipment. We do not depend on external suppliers of electronic controllers.

ELECTRONIC PRODUCTS DESIGN

BLUETOOTH-BASED AMF CONTROLLER

Use BlueTooth to collect data, download the Event Log, set up the controller, and check the measurements. The list goes on and on.


THE BEK3-BASED AMF PANELS FEATURE REMOTE MONITORING

The BeK3 AMF controller features CANbus and MODbus remote control monitoring options. You can connect RS485 drivers to get GSM and TCP/IP monitoring. You can purchase separately the MODEM and TCP/IP server.

WOULD YOU LIKE TO SEE THE SAME VERSION OF THE PANEL AFTER 12 YEARS OF SERVICE DAY AND NIGHT ON THE SEASIDE?

Believe it or not, after 12 years of continuous service day and night on A BEACH RESORT, the 40kVA AMF panel is perfectly functional. The customer contacted us to replace the metal cabinet!

BEK3 AMF CONTROLLER FEATURES A SILICON GASKET.

Thanks to the silicon gasket, which features an IP65, the internal parts of the panel are unaffected by the elements.

INTERNAL CONNECTIONS OF A 49KVA PANEL

To avoid this problem, a fibre-glass enclosure should be used when a panel works in saline marine environments. Regular maintenance with special coating must be periodically carried out.

WHY USING AN AMF PANEL DOES INCREASE THE LONG-TERM RELIABILITY OF A STANDBY GENERATOR?

All, and always, is about money. To save money, you install the AMF controller on the generator. This is a bad idea. Of course, it is a good idea for people who do business with the service. However, the goal of Bernini Design is different. We believe it is a serious solution. We believe that the final customer deserves safety.

THE WRONG WAY TO MAKE A STANDBY SYSTEM.jpg

In the above schematic,  the overvoltages can easily damage the generator. No matter the insulation you can reasonably provide. The stray capacitance of the connection will win. Yes, you can find cheap ATS panels. But this is not a professional solution at all. The following picture presents one of the optimal solutions,

THE SAFEST SOLUTION FOR A STANDBY GENERATOR

In the drawing, you can observe that the AMF panel prevents overvoltages from reaching the generator. The AMF controller can start the engine via an auto-start module installed on the generator [1] or directly via the configurable input-outputs line[2]. Both solutions are more than acceptable.
