CONTROLLER / FAULT CODES
PROGRAMMABLE CONTROLLER
The ICS programmable controller is an electronic engine governor that provides a means of controlling and limiting
engine speed by adjusting the fuel control lever with a proportional actuator.
The controller is factory programmable and has no manual adjustments.
CALIBRATION
Calibration and programming can only be done by the factory.
TROUBLESHOOTING GUIDELINES
Please follow the checklist below to troubleshoot your ICS controller.
1. Check battery voltage for stability and correct value. The LED will turn on for one second when the controller is first
powered up.
2. Check the actuator linkage for binding and backlash.
CHECKING PERFORMANCE CONTROL (ELECTRICAL GOVERNOR-STATIC CHECK)
To determine whether a governor problem is being caused by the actuator or the control module, perform the
following static check exactly in order shown.
A pair of jumper wires and a known good 12-volt battery is required.
1. Disconnect red and green wires from the control module to actuator.
2. Attach jumper wires from battery to RED and GREEN wires to actuator.
A. Attach 12 volt + (positive) to RED wire.
B. Attach 12 volt – (negative) to GREEN wire.
3. Actuator should move throttle lever to wide open position.
A. If actuator does not move it is defective. (Replace).
B. If actuator moves throttle to wide-open position, the module is defective. (Replace).
FAULT CODES
The ICS controller is capable of identifying certain fault conditions and alerting the user to them. A flashing LED
indicates the fault conditions. The current fault code list is shown on the following page. Please note the following:
1. When power is first applied to the controller, the LED will flash just once for one second to indicate that the LED is
working.
2. If there are multiple faults, the LED will flash them all in sequence. Count the flash codes to determine the fault
conditions or connect the Calibration Tool to observe the fault conditions. (Use the “Display Faults” option under the
Monitor Menu).
3. If there are no faults, the LED will flash once at reset and from then on indicate the detection of engine speed. A
continuous ON LED indicates that a valid engine speed is being sensed.
4. The controller will attempt to shut down for some faults and will not permit starting after reset with faults 1, 5 and 8.
