The PLC Pre-programmed Functions:
The PLC has been preprogrammed to monitor and control the state-of-charge of the KAPower
capacitor module based on temperature, voltage, and time. Once a voltage signal is received
at pin four (4) of the Wiring Interface Connector, the PLC “wakes-up” and will determine when
and how long to keep the contactor closed. Anytime the LED Status Indicator is illuminated,
the contactor is closed. In a typical engine-starting event, the LED will illuminate during engine
cranking, and then go out for several seconds after the engine has started. The LED will then
illuminate again and could remain illuminated for several seconds based on the condition of
the KAPower module. The LED may even begin to “cycle” depending on the vehicle/vessel, or
system voltage during the recharging events.
The J1939 connector is used for KBI factory programing only. Contact KBI for details.
