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.
ECM Boot-up Delay
ECMs can take up to 10s to boot-up when they are first powered. Ensure that
the crank time is long enough to take this into account. If extended cranking is
not desired the glow plug (preheat) time can be set to turn on the fuel relay for a
set time before cranking begins. Ensure that no configurable output is set to
preheat. Another option is to enable the Auto Power ECM setting. This allows
the fuel relay come on in the AUTO mode. See the next section below.
3.8.1 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 ready to go when the user desires to start the generator. When the
controller exits from the RUN mode the ECM Power Delay setting controls the
amount of time the GSC400 waits before turning on the fuel output. This is done
to prevent the generator from starting up unexpectedly if it hasn’t fully shut down
when the controller entered the Auto mode.
3.8.2 Diagnostic Trouble Codes (DTCs)
The GSC400 has a DTC feature that, when enabled, allows the controller to
receive currently active DTCs (DM1) messages and display then on the screen
as well as optionally store then to the Event Log. The controller can also receive
previously active (DM2) messages and display them on command. DM2
messages are intended for technician troubleshooting and are not stored to the
Event Log.
The GSC400 supports the following J1939 standards when reading DM1
messages:
1. Single package frame J1939-71
2. Multi-packages frame J1939-21
