The D+ CHG ALT is combine input and output terminal. When the genset starts, the terminal
provides controlled power output to excite the charging alternator. Once the charging alternator is
excited and starts providing voltage to battery, this terminal is used as input to sense the output
voltage of the charging alternator. In case of the charging alternator failure the GCU acts as per the
pre-configuration settings.

Important Note: The sensor common point (SCP) terminal (Pin # 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 analog 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
analog sensor measurements are always available in a wide variety of field
conditions.
2.13 Deep Sleep Mode Feature
Deep Sleep Mode is a useful feature to prolong the battery life.
In this mode, normal functions of the controller are suspended, and controller is placed into its lowest
power consumption state. Controller maintains the status and alarms it had before Deep Sleep Mode.
When the controller wakes up, normal operations are resumed automatically.
The controller goes in Deep Sleep Mode when there is no user interaction for the pre-set Deep Sleep
Mode Delay.
• This mode is disabled in AMF mode.
• In Manual mode, press and hold “START”/“STOP” key for minimum one sec to come out of
Deep Sleep mode.
