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 posi-
tion.
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 fl 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 fi rst applied to the controller, the LED will
fl ash just once for one second to indicate that the LED is
working.
2. If there are multiple faults, the LED will fl ash them all
in sequence. Count the fl 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 fl 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.
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 software programmable and has no
manual adjustments.
CALIBRATION
ACT is a PC (personal computer) based software
calibration and monitoring tool. ACT is designed
specifi cally for use with engines equipped with
the Stanley controller. Stanley Hydraulic Tools
recommends that an authorized and certifi ed
dealer perform calibration of this unit.
Once the controller has been programmed, ACT
may be disconnected. The Stanley controller
will continue to operate normally with ACT either
connected or disconnected.
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
fi rst powered up.
2. Check the actuator linkage for binding and backlash.
