5.
The current maximum RPM setting for this parameter
will be flashed by the LED's.
6.
Use the +/- buttons or 4-digit keypad numerical entry
method to set a new RPM value for the VARIABLE

UPPER LIMIT.

7.
Turn the Potentiometer such that the minimum voltage
is present on Terminal F.
8.
Access Menu 1 (LED 1).
9.
Press the 7 button to access the VARIABLE LOWER
LIMIT parameter. This step also causes the IGC700 to
remember the potentiometer's minimum position. At
this point the Bar Graph should display a lower RPM
than it did for the maximum position.
10. The current minimum RPM setting will be flashed by
the Bar Graph.
11. Use the +/- buttons or 4-digit keypad entry numerical
entry method to enter a new value for the VARIABLE

LOWER LIMIT.

Crank Termination Setting
This parameter must be set higher than the maximum
cranking speed (RPM). This helps the IGC700 to determine
if the engine is cranking or running. Otherwise the IGC700
will invoke its Speed Control algorithms instead of its
Starting Fuel algorithms during the starting cycle. When the
IGC700 is in the RUN mode (the SETUP LED will be
steady on), the LED labeled 'DERIVATIVE' illuminates as
an indicator to notify you that the IGC700 is in the Start
cycle. Once the engine is running, the LED labeled 'GAIN'
illuminates indicating the IGC700 is in the Engine Running
mode and is therefore invoking the Speed Control
algorithms. If you are attempting to start the engine and you
notice the Gain LED lighting you may need to increase the
Crank Termination Setting. To increase the Crank
Termination Setting:
1.
Gain access to MENU 2 (Press and release the MENU
button until Menu 2 is active).
2.
Press
the

button
TERMINATION parameter. The Bar Graph will flash
the present RPM value for this parameter.
3.
Enter the desired RPM value as a four-digit number.
For example, 275 RPM would be entered as 0,2,7,5 and
press ENTER. After pressing the Enter button, the Bar
Graph will flash the new setting for CRANK
TERMINATION.

Saving IGC700 Settings
Press and Hold the RUN button until the RUN/SETUP LED
stops flashing. This causes the IGC700 to save all settings
into permanent memory. Without doing this all settings will
be lost when the IGC700 is turned off. The IGC700 will now
be in RUN mode, which is verified by a steady RUN/SETUP
LED.
Advanced Configuration
Additionally, there is a group of Advanced Configurations that
do not necessarily need to be preset for basic engine operation.
These are listed below. (Their factory default states should
not hamper basic operation.)
1.
Staring Fuel Inhibitor control. (SFI is disabled per factory
configuration.)
2.
Speed Ramping for acceleration and deceleration rates.
3.
Droop settings (All Droop settings are preset to 0%).
Starting Fuel Inhibit Control
This parameter gradually increases the amount of fuel during
the engine start cycle, which eliminates unnecessary smoke.
The higher the setting the more time it takes to reach full fuel.
Tip: You may have to press the + or - button several times
before you will see any change in Bar Graph LED's. This
is due to the fine-tune resolution between LED indicators.
1.
Enter SETUP mode.
2.
Enter the START FUEL RAMP parameter. (Press and
release the MENU button until MENU 0 is active, then
press the 6 button).
3.
Use the +/- buttons to adjust the Bar Graph.
Tip: The Engine should start more quickly as this value is
decreased. Therefore a value of zero will not restrict any
fuel.
Starting Fuel Preset Point
This parameter determines how much fuel to begin with
before fuel ramping engages.
1.
You must be in SETUP mode.
2.
Enter the START FUEL BEGIN POINT parameter.
(Press and release the MENU button until MENU 1 is
active then press the 6 button).
