The Be142 Description
The Be142 is 3-phase AMF controller. All parameters, alarms and operating functions are indicated by means of a high-luminosity display. The AMF controller Be142 interfaces with resistive or digital sensors. It measures Vac, Aac, Vdc, Hz, hour count, R.p.m., Oil Pressure, Engine Temperature, Battery Vdc and Fuel Level. Software for remote monitoring is also provided free of charge. The Be142 provides MODBUS via RS485. The AMF controller Be142 complies with NFPA-110 / NFPA-99. By using our TCP-IP server you can monitor and control the Be142 via INTERNET. Option for remote control by GSM is also provided. We provide support to make your own AMF Control Panels.

DECODING THE AMF CONTROLLER BE142 ENGINE ALARMS
[ALARM ER10] MAINTENANCE REQUEST WARNING You are required to carry out the maintenance of the engine. Once a timer expires, the Be142 indicates the [Er.10] on display. To clear the alarm, enter the manual mode, push and hold the [ACK-F10] button for at least 20 seconds. You are allowed to modify the programmed Maintenance timer at anytime. To restart the Rental Timer, you are required to enter in programming and exit the programming (we recommend that you limit the access to the programming by using a password).
[ALARM ER11] FAIL TO START SHUTDOWN The engine failed to start after an automatic start cycle. You are required to check the engine before clearing this alarm.
[ALARM ER12] LOW FUEL ALARM This could be a warning or a shutdown. The display will provide additional information about it.
[ALARM ER13] BATTERY VOLTAGE ALARM. You are required to check the status of the battery before clearing this alarm.
[ALARM ER14] LOW OIL PRESSURE ALARM. This is a critical warning or shut down alarm. Immediate action is required before restarting the engine.
[ALARM ER15] HIGH TEMPERATURE ALARM. This is a critical warning or shut down alarm. Immediate action is required before restarting the engine.
AMF CONTROLLER BE142 OFF MODE OF OPERATION
Push the button [OFF] 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 push buttons on the front panel to energize the display.
MANUAL MODE OF OPERATION; STARTING THE ENGINE
Note: default programming for input #36 (Emergency input) is ‘normally closed ‘. To inhibit the alarm [Er.08], you are required to connect terminal #36 to ground (Emergency input).
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 until 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 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.
AMF CONTROLLER BE142 MANUAL MODE OF OPERATION; ACTIVATING A CIRCUIT BREAKER
Select the MANUAL mode, start the engine (see above) and wait for voltage presence. Push the [ I ] (KG) push button 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. In manual mode the CHANGEOVER timer lasts one second.
AMF CONTROLLER BE142 AUTO MODE OF OPERATION
Note: default programming for input #36 (Emergency input) is ‘normally closed ‘. To inhibit the alarm [Er.08] you are required to connect terminal #36 to ground (Emergency input).
Push the [AUTO] push button until the green LED illuminates. The engine starts when the Be142 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 a cooling down time. 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 Be142 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 Be142 can start and stop the engine according to programmed inputs.
AMF CONTROLLER BE142 TEST MODE OF OPERATION
Push the [TEST] push button until the green LED illuminates. The Be142 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 Be142 is in AUTO or TEST, the [Er.09] will energize. To clear the alarm, select the OFF mode .
AMF CONTROLLER BE142 GSM MONITORING
You can start / stop the generator, browse the instruments, clear the alarms and miscellaneous operations. You are required to connect the BE16 adapter. In case you have more that one mobile phone you can use our PHONEBOOK software configurator.
AMF CONTROLLER BE142 MODBUS
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.
