Group Outputs
Group functions have been designed to allow multiple output functions to be bundled together and assigned to a single
switched output pin. The definition of a group output follows:
When any of the functions in a group is active (OR logic), the assigned switched output will be active.
Group Functions
Name Active Mode Description
Group #1 Group Dependent Must be set from RapidCore Configuration software.
Group #2 Group Dependent Must be set from RapidCore Configuration software.
Group #3 Group Dependent Must be set from RapidCore Configuration software.
Group #4 Group Dependent Must be set from RapidCore Configuration software.
Example: Low AC Frequency, High AC Frequency are bundled in 'Group #1' and assigned to Switched Output D. This output is
connected to an external indicator lamp labeled 'AC Frequency Warnings', allowing one output to indicate there is a warning
with the AC frequency. The following table shows the output state based on the warnings status.

Pull and Hold Coil
On some engine systems the fuel pump has two coils. This is because the initial power on of the fuel solenoid requires
substantial current (Pull Coil), but only needs a small amount of current to hold it in place (Hold Coil).
1. Hold Coil (Fuel) is energized.
2. Pull Coil is energized for the first 1.6 to 1.8 seconds of preheat. If preheat is disabled the pull coil is energized at the
beginning of cranking; the crank output turned off for that time period.
3. This is repeated for each crank attempt.
Configuring a switched output to Pull Coil automatically configures the engine logic necessary for a Pull Coil system.
Note: The pull coil feature does not operate when the fuel output is activated by the Auto Power ECM feature or when
requesting stored DTCs (DM2 codes). See the J1939 section for more information on these features.
