PROGRAMMABLE CONTROLLER
The Stanley 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 preset and has no manual adjust-
ments.
TROUBLESHOOTING GUIDELINES
Please follow the checklist below to troubleshoot your Stan-
ley controller.
1. Check battery voltage for stability and correct value. The
LED will turn on for one second when the controller 4500 is
rst powered up.
2. Check the actuator linkage for binding and backlash.
Checking Performance Control™ (Electronic
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 Stanley controller is capable of identifying certain fault
conditions and alerting the user to them. A ashing LED
indicates the fault conditions. The current fault code list is
shown on the following page. Please note the following:
1. When power is rst applied to the controller, the LED will
ash just once for one second to indicate that the LED is
working.
2. If there are multiple faults, the LED will ash them all
in sequence. Count the ash 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 ash 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.
