Standby Output If set the aux input to fault stop, then when the signal at the input is valid, the engine will stop instantaneously, and the LCD display “ALARM：EXT. ALARM”，the buzzer warn. NOTE:

u The data of low oil pressure pre-alarm is from the measuring of the oil pressure sensor, and the data of low pressure stop fault is from the measuring of the oil pressure sensor (set for no use at factory) or the oil pressure switch state.

u The data of high temperature pre-alarm is the water position from the measuring of the temperature sensor, and the data of high temperature stop fault is the water position from the measuring of the temperature sensor (set for no use at factory) or the temperature switch state.

u The rotating speed of the engine typically from the measuring frequency of the speed sensor mounted on the flywheel of the engine, if no speed sensor equipped in the system, the controller will take the voltage frequency of the generator output as the controlling and fault protection parameter. To be convenient for the user, part of the data is rotating speed, RPM=HZ*30.

u Generator fault during the running of the generator: stop instantaneously after the high temperature , or low pressure, or overspeed, or under speed occur. But the low speed and low pressure required the idle delay set to 0 (without idle function) to active protection, or it won't be active.
