Parameters
The controller will work with any generator as long as it supports the standard messages listed in the
SAE J1939 specification. Standard messages include oil pressure, engine temperature, and engine
speed. Some engine control modules have proprietary messages that are intended for specialized
devices and are not displayed by the controller.
The following is a list of parameters that can be accessed through use of the J1939 bus. In order to for
each one to function properly, J1939 must be selected as the 'Signal Source' under each individual
parameter.
1. Engine Speed
2. Engine Temperature
3. Oil Pressure
4. Oil Level
5. Fuel Level
6. Fuel In Basin
WARNING
: There is a special case where parameters show N/A in place of the value. This
means that the engine may still be starting up and controller has not yet accessed that
information. If controller displays N/A during running and has not shut down on 'Loss of ECM',
it means that the controller and ECM are communicating but not receiving those parameters.
Troubleshooting
The following section outlines some common issues seen when wiring and configuring the controller for
J1939.
ISSUE
SOLUTION
Check for Communications
Set 'Engine Temperature' to J1939 and go into 'Auto' mode. Verify that
the 'N/A' is not displayed for engine temperature.
Generator Not Starting
Check wiring to the ECM. Most have multiple power and ignition inputs
that must be connected for it to operate properly.
Generator Restarts on
Shutdown
Change 'ECM Power Delay' to a higher value.
The ECM should start and run the engine – even if there are no CAN communications with controller –
when the controller turns on the fuel and crank outputs. If there are no communications between the
ECM and controller, the controller will not stop the crank cycle when the engine is running as it is not
receiving the engine speed.
