CAN Bus (J1939)
The controller is able to communicate with electronic control modules (ECMs) on engines that follow the
SAE J1939 specification. Examples of standard messages are oil pressure, engine temperature and
engine speed. Some engines may have proprietary messages that will not function with the controller.
The following ECMs are confirmed to be supported by the controller.
Generic J1939
John Deere JDEC
Volvo EMS
Cummins CM850
Yanmar ECO
Detroit Diesel
Volvo EMS2B
Izuzu 4H
GM PSI E-Control
SETTING
DESCRIPTION
ECM Module
Choose the one of the available ECM modules from the list.
Loss of ECM
If no CAN messages are received for more than 6 seconds, the
controller shuts down the generator.
DTC Display
Enables or disables active fault messages (DM1) monitoring. See
for more information.
Active DTC Log
Enables or disables the storing of active faults (DM1). See
for more information.
Read Stored DTC
Enables or disables the ability to request stored fault codes from the
ECM (DM2). See
for more information.
Auto Power ECM
When enabled, the fuel relay is enabled in Auto mode so that the
ECM is already powered up and initialized before the user decides to
start the generator.
ECM Power Delay
Used in conjunction with 'Auto Power ECM', on generator shutdown
the controller waits the ECM Power Delay before turning on the fuel
relay again. This is to prevent unwanted start ups due to the generator
not being completely shut down.
Cummins Idle
When enabled, the controller tells the Cummins generator which
speed to run at. GC1 is the newest protocol and GCP is for older
engines. A switched input must be programmed to 'Idle Mode' for
feature to function correctly.
SPN Conversion
Select the SPN conversion method. See
for more information.
EMS2B Frequency Select
For Volvo EMS2B Engine Control Modules only.
EMS2B Accelerator Pedal
For Volvo EMS2B Engine Control Modules only.
WARNING
: If using 'Cummins Idle Speed' and powering the ECM externally you may get the
error message 'J1939 Erratic'. The ECM expects the speed update to be sent continuously
and if it is not the ECM thinks there is a problem with the J1939 communications.
