2452-3
Generator Total Real Power : Voltage Above Normal     The ECM has not detected a load signal from the EMCP 4.3.
The ECM is not receiving an analog load signal at terminal J1-16 from a power sensor.     The code is logged.    Background InformationThe control system monitors the generator output power in order to control the air/fuel ratio accurately. The control system uses a load signal from one of the following sources in order to monitor the generator output power:
Electronic Modular Control Panel 4.3 (EMCP 4.3)
Programmable Logic Controller (PLC)The PLC is also referred to as a power sensor. The load signal from the power sensor is an analog voltage. The load signal increases from 0 VDC to 4.8 VDC as the generator output increases to the maximum output.
