The charge fail is a combined input and output terminal. When the genset starts, the terminal provides controlled power output to
excite the charging alternator. After the excitation is successfully done, the controller reads the charging alternator's output voltage
for monitoring its health. The action for charge fail is configurable.
3.8 Sensor common point

Range
Accuracy
NOTE
The sensor common point (SCP) terminal 41 of the controller should be directly connected to an electrically sound point on
the engine body. This point on the engine body should serve as a common reference point for all analogue sensors such as
those for measuring lube oil pressure, engine temperature and fuel level. The electrical cable used for the connection
should not be shared with any other electrical connection. Such a wiring practice is strongly recommended to ensure that
there is negligible potential difference, if any, between the engine body and the controller's SCP terminal, and, predictable
and accurate analogue sensor measurements are always available in a wide variety of field conditions.
