ATS CONTROLLER
An ATS controller is an electronic module committed to transfer the LOAD from Mains to Generator and vice versa. In other words, the ATS controller automatically or manually manages and drives the connection assignment of the LOAD to MAINS or GENERATOR. The ATS controller is the key component of an ATS panel.
WHY TO USE THE BE242 CONTROLLER?
A traditional ATS controller needs as many meters of cables, many connections and accessories. The Be242 ATS controller is made of two parts. You will change the way to make an ATS panel. On the backplane, you install the ATS controller relay board. It will be easy to connect any kind of engine. You will benefit from the following features

THE BE242 ATS CONTROLLER DOES NOT NEED A SQUARE HOLE
MAKE A SIMPLE ROUND HOLE!
THE BE242 DOES NOT NEED RELAYS
FIRST IN THE WORLD 20mm-THICK ATS CONTROLLER
You will fix the controller on the door of the ATS panel by making 4 holes. You will make a round hole for the interconnection cable, supplied by us. No square hole is required. It is a 5-minute job. The ATS controller will benefit from the shield effect created by the plate of the metal door.
ATS CONTROLLER INSTALLATION MANUAL
You will connect the generator and the engine start-stop circuits to the relay interface module.
You are no longer required to wire connections to the rear door panel. The relay board includes auxiliary relays and short-circuit-proof components. To make a professional Automatic Transfer Switch panel, you only require a metal or plastic cabinet, battery charger, current transformers, and contactors. You can choose the best solution by using the configurable INPUT-OUTPUT options.
Despite its square shape, the ATS controller needs only a round hole for the interconnection cable and emergency switch.

TYPICAL ATS PANEL WIRING DIAGRAM
THERE ARE TWO BASIC CONFIGURATIONS: CONTACTOR-BASED AND MOTRIZED-BASED
THE CONTACTOR BASED DIAGRAM
GENERATOR-LOAD The generator is electrically connected to the LOAD via the KG (contactor of the generator). This is possible only when KM is open. The KM-AUX are the auxiliary contacts fitted on the body of the KM. When the KM is open, the auxiliary contacts are closed in a way to enable the KG. The BE242 energizes the coil of the KG by supplying voltage to the terminal KG. The other side of the coil is connected to the neutral via the auxiliary contacts. When switching the Generator to Power Utility the user may observe a short ‘power outage’. Normally it is about 2 seconds. This is the typical behaviour of the automatic transfer switch: BREAK-BEFORE-MAKE. This is a way to protect the appliances from overcurrents.
To get the KG closed you need KM-AUX and KGC closed
UTILITY POWER-LOAD The utility power is connected to the LOAD via the KM contactor. The coil of the KM is energized by the output KM of the ATS controller. When the KG is open, it closes its auxiliary contacts. This provides a neutral to the other side of the KM coil. Inside the BE242 REALY BOARD, the relays that drive the KM output feature normally close contacts. By doing so, the ATS controller gives priority to UTILITY POWER in case the ATS controller is damaged or without supply. If we use the normally open contacts, all the time we remove the DC supply or we remove the battery of the engine, we disable the contactor of the mains. The user will get an unexpected power failure in the building even if the UTILITY POWER is healthy. This is why we use the normally closed contacts. In case of real power failure, the ATS controller energizes the KM. This prevents the panel from supplying the LOAD with improper electrical parameters. Once the KM is open, the auxiliary contacts KM will close. This is one of the mandatory conditions to close the KG (the KM must be open in the first place).
THE MOTORIZED SWITCH BASED DIAGRAM
The motorized changeover consists of a motorized switch with 3 positions: GENERATOR, OFF and MAINS. An electric motor drives the switch to move in a particular position. The motorized changeover has several advantages.
Firstly, it can manage big currents if compared with a contactor-changeover. Secondly, it does not require power to hold the position. Thirdly, it is a cheap and safe solution for high-power switching. O
ATS CONTROLLER IN A DUAL LOAD SYSTEM
The following wiring diagram presents the basic connections of a dual-load ATS controller configuration.
By using the Be242, you can use one generator capable of serving two separate loads. The generator will supply the load that is affected by a mains failure. This application is typical in private houses. By purchasing one generator you can solve the power outage issues for two houses. You need to make to ATS panel of a suitable size.
ATS CONTROLLER IN A DUAL GENERATOR SYSTEM
The following wiring diagram presents the basic connections of a dual-generator ATS controller configuration. With Be242 you can connect two generators as an emergency standby to one single load. The BREAK-BEFORE-MAKE configuration is mandatory for the protection of the load. In case of a prolonged mains failure, you can set up ENGINE 1 as a master. In case of starting failure, the second engine will start. The generator will supply the load. You are required to include the ATS controllers and transfer switches in the same cabinet.
SETTING UP THE ATS CONTROLLER
The Be242 is user-friendly. The installation manual will help you in making the panel. The ATS controller is delivered with default settings for 400V 3-phase and diesel engines. You can program the ATS controller on-site in a few minutes. You can arrange a dual-set configuration or dual-load configuration. The Be242 accepts single or tri-phase ALTERNATING voltage connected to the mains and generator. You can choose configurations single-phase or tri-phase for generator and mains. To drive the motor of the transfer switch connect the KM and KG outputs as indicated in the wiring diagram. Use the battery of the engine to supply the ATS controller. You can use the Be242 controller for up to 1000kVA electrical system.
ATS CONTROLLER OFF-MODE OF OPERATION
Push the button [OFF] of the ATS controller to enter the OFF mode. The OFF mode clears the fault alarms and allows you to read or program parameters.
The Display and LEDs are turned off and a dot on the display will blink slowly. Push one of the pushbuttons on the front panel to energize the display.
MANUAL MODE: STARTING THE ENGINE
The MANUAL mode allows manual control of the engine and circuit breakers. Push the [MAN] push button to select the MANUAL mode. Push the [START] push button of the ATS controller until the engine starts; the display indicates the message [. . . .] during the starting attempts or [! ! ! !] if preheat has been programmed.
When the engine is running, the green LED turns on.
To stop the engine, push the [STOP] push button of the ATS controller until the [StOP] message appears on the display. If the engine has already stopped, it is possible to reset the STOP sequence by pressing the [STOP] push button.
MANUAL CHANGEOVER
Select the MANUAL mode, start the engine and wait for voltage presence. Push the [ I ] (KG) push button of the ATS controller to close the Generator circuit breaker.
To transfer the Load to Mains, push the [I] (KM) push button (the [KG] will open). To open a Contactor, push the [O] push button of the BE242 controller. In manual mode, the CHANGEOVER timer lasts one second.
ATS CONTROLLER AUTO MODE OF OPERATION
Push the [AUTO] push button of the ATS controller until the green LED illuminates. The engine starts when the Be242 detects a Mains failure. The Contactor of the MAINS (KM) opens after the BREAKER timing. After the warm-up time, if the voltage and frequency are within the settings, the circuit breaker of the generator (KG) will close.
If the Mains restores, the KG will open. The KM will close following a programmed changeover timing. The Engine will stop after cooling downtime. If the engine shuts down, the KM closes independently of the Mains status if the [P.48] is [ON] (NFPA-110 mode), otherwise, the KM will close only if the Mains is within programmed settings. In AUTO mode, the BE242 will periodically test the engine if the parameters [P.41] and [P.42] have been programmed. During this test, the green LED of the AUTO mode will continue to blink. In AUTO mode, the Be242 can start and stop the engine according to programmed inputs.
ATS CONTROLLER TEST MODE OF OPERATION
Push the [TEST] push button of the ATS controller until the green LED illuminates. The Be242 ATS controller starts the engine and transfers the load to the Generator if [P.17] is [on]. To stop the engine, select the AUTO mode (if Mains is present) or select the OFF mode. If you push the [STOP] push button when the ATS controller is in AUTO or TEST, the [Er.09] will energize. To clear the alarm, select the OFF mode.
