2.3 AUTO mode
Note: default programming for input #36 is ‘normally closed ‘. To inhibit the alarm
[Er.08]
you are required to connect to ground terminal #36 (Emergency input).
Push the [AUTO] pushbutton until the green LED illuminates. The engine starts when the Be42 detects a
Mains failure (see table 7.01A). 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 contactor 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 a cooling down time (see tables 7.02 and 7.03). 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 Be42 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 Be42 can start and stop the engine according to
programmed inputs (see Tables 7.06 and 7.07).
2.4 TEST mode
Push the [TEST] pushbutton until the green LED illuminates. The Be42 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] pushbutton when the Be42 is in AUTO or TEST, the [Er.09] will energize. To
clear the alarm, select the OFF mode (section 8.0).
2.5 PROGRAM mode
The PROGRAM mode allows parameter programming and modifications of settings. A password can be set to
protect from unauthorized access (see 6.0)
.
2.6 CALIBRATION mode
The CALIBRATION mode allows calibration of all analogue measurements (see 12.0).
2.7 TROUBLESHOOTING mode
The TROUBLESHOOTING mode is used to diagnose system faults (see 13.0).
