CODE
FAULT
ENGINE
SHUT-
DOWN
CORRECTIVE ACTION
1
APECS unit not calibrated
yes
Calibrate APECS unit.
Check parameter settings. Over speed criteria may be too sensitive.
Check for electrical noise entering controller.
Check wiring and connections.
Check case ground.
Make sure linkage moves freely, without backlash.
Check tip of speed sensor.
2
Engine speed excessive
yes
3
Engine speed unusually low
yes
Check parameter settings.
Check linkage and the actuator travel.
Ensure that load is not greater than engine capacity.
4
Engine shutdown due to engine pro-
tection input
yes
Check parameter settings.
Check what may have triggered the protection input.
5
Factory settings lost
yes
If calibration fi le is available, download the fi le and cycle power again.
If controller still does not work or if no calibration fi le is available,
consult factory.
6
External pot out-of-range
no
Verify that pot is wired correctly.
Recalibrate external pot.
7
Accelerator position / idle switch
confl ict
no
Verify that signals are working and synchronized.
8
Controller unit failed
yes
Electrical noise may be entering the controller.
Check wiring, shielding and connections to controller.
Cycle power to engine.
If controller still does not work, consult factory.
9
Limiting excessive actuator current
no
Check actuator for short to ground or low resistance.
Check parameter settings.
Check linkage and actuator travel.
Ensure that load is not greater than engine capacity.
10
Engine speed input signal missing
no
(Active only in Auto crank mode).
Check speed sensor wiring.
Check starter motor.
11
Auto crank unable to start engine
no
Check fuel.
12
Auxiliary output is shorted
no
Check the lamp or relay hooked to the output. If fault is still present,
consult factory.
13
Auxiliary output #2 is shorted
no
Check the lamp or relay hooked to the output. If fault is still present,
consult factory.
14
Actuator disconnected or open circuit
no
Check actuator wiring and actuator resistance.
Resistance should be less than 10 ohms.
