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.
