There is also a Loss of ECM submenu in the J1939 menu that you should enable if using
J1939.
When enabled, the controller will shut down on a failure when certain J1939
messages have not been received on the CAN bus for 6 seconds.
Also, when there has been no data received for a specific parameter, that parameter
will display “N/A” in place of the value.
This will disappear once data for the
parameter is received from the bus. This will also occur on startup until the GSC400
accesses the data from the bus. Note that loss of ECM may not be triggered since other
parameters may be receiving data from the bus.
6.1.1
Auto Power ECM
Some Engine Control Modules (ECMs) require significant time to power up and initialize
before they are ready to control the engine. The GSC400 can be programmed to leave
the fuel relay output on while in the AUTO mode by enabling
Auto Power ECM
. This
will ensure the ECM is already powered up and read to go when the user desires to start
the generator. When the controller enters the Auto Mode the
ECM Power Delay
setting
controls the amount of time the GSC400 delays before turning on the fuel output. This is
useful to prevent the generator from starting up unexpectedly if it hasn’t fully shut down
when the controller entered the Auto Mode.
6.1.2
Cummins Idle Speed
The GSC400 can switch between idle and normal operating speed on Cummins
generators. When the fuel relay is on, the GSC400 continually sends out a speed
command every 250ms to tell the generator which of the two speeds to run at. A digital
output must be set to
Idle Mode
(see Table 15 on page 67) and when this digital input is
active the generator runs at idle speed; otherwise it runs at normal operating speed.
To enable this feature set
Cummins Idle
to GCP Enable or GC1 Enable. GC1 is the
newest protocol while for older engines you will need to use GCP.
If you are powering the ECM externally you may get an error message (if Cummings Idle
Speed and Diagnostic Trouble Codes – see below – are enabled), “J1939 Erratic”. The
