12 GCU-3000
3.16 CANBus J1939 Transducer KCU-04 (Optional)
The KCU-04 module is used with CPU equipped
engines using the J1939 CAN Bus protocol. It is
connected to any one of the four slots on the back of
the GCU-3000 controller.
For J1939 related settings refer to Setting Line (21).
Installing the KCU-04 provides the GCU with the
following information.
● Temperature reading in ˚C or ˚F
● Oil Pressure reading in Psi or Bar
● High temperature warning and shut-down alarm
● Low oil Pressure warning and shut-down alarm
● Over-speed warning and shut-down alarm
● Under-speed warning and shut-down alarm
● Low fuel level warning and shut-down alarm
When you connect the KCU-04 module the GCU
disables the High Temperature, Low Oil Pressure and
Low Fuel Level protections automatically and all related
programming lines are automatically eliminated. You
don’t need to install any of sensors, this information
now comes from the CAN Bus, and protections
relegated to the engine CPU. The GCU’s job is to show
warning, alarm and shutdown messages using the
universal icons on the front panel.
The GCU does not disable its own over speed and
under speed protection, Both of GCU and the engine
CPU will shut-down the generator for over speed.
