The Be142 continuously monitors the status of the MAINS. The Be142 allows you to set low/high limits for Mains Voltage and low/high limits for the Mains Frequency. When the voltage and the frequency are within the limits, the Be142 AMF controller transfers the load to the Mains. If the voltage drops below the lower limit (or rises above the high limit) or, if the frequency drops below its limit (or rises above its limit), the Be142 will disable the Mains circuit breaker. This prevent, after a programmable delay, a severe damage to your load. So, we can say that Be142 prevents, in the first place a damage to your systems. Then, if the failure persists for a long time (a programmable timer is available ranging from seconds up to hours) the Be142 will take care to start you emergency generator. Once again the Be142 does its business to check the quality of the generator voltage and frequency. Once the parameters are within the programmed limits, the BE142 will enable the generator circuit breaker. Now, in case of prolonged power outages, your load is safely supplied by your emergency generator. Be142 as we understood before does not forget to pay attention to the Mains. So, when the Mains parameters will return within the programmed settings, the Be142 AMF controller will transfer the load to MAINS. This will happen after a delay that will ensure that the Mains is in stable conditions. Once your load is connected to the Mains, the engine will run for a programmable time off-load. After that, the engine will stop and the BE142 is ready for a new power outage.

How to make AMF panels tutorial
What is an Automatic Mains Failure controller? The AMF controller is a kind of module used in generator control panel when you have to control a generator that is connected in standby configuration. It is about a system that is waiting for a failure of the power utility.

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.
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.
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.
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 .
