AUTOMATIC TRANSFER SWITCH CONTROLLER AUTO MODE OF OPERATION
Push the [AUTO] push button until the green LED ‘AUTO’ illuminates. The engine starts when the Be28 detects a Mains failure. The contactor of the MAINS (KM) opens after a delay. 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 programmable changeover timing. The engine will stop after a cooling down time. If the engine shuts down, the KM closes only if the Mains is within the programmed settings. In AUTO mode, the Be28 can start and stop the engine according to programmable inputs also.
AUTOMATIC TRANSFER SWITCH TEST MODE OF OPERATION
Push the [TEST] push button until the green LED illuminates.The Be28 starts the engine and could transfer the load to the Generator according to the settings of the panel manufacturer. To stop the engine, select the AUTO mode (if the Mains is present) or stop the engine in MANUAL mode. If you push the [STOP] push button when the Be28 automatic transfer switch controller is in AUTO or TEST, the [Er.09] will energize. To clear the alarm, select the OFF mode.
This is a flexible solution by using the Bernini Design impressive SERVER technology. No one can do better. No more than that you can ask. This is the demonstration on how Bernini Design control the 'Fabric' of digital communications for generator remote control systems.
You can transfer the load to generator and mains by using your mobile phone via simple SMS commands. You are required to connect the BE16 adapter. In case you have more that one mobile phone you can use our PHONE BOOK configuration software.
Cost effective remote monitoring system by using a MODBUS to USB protocol adapter. You can connect a computer as far as 1000 meters away. You can download our free of charge software for generator control monitoring.
