Display Description
59
Parallel Coil Fault: Check the connections to the Coil’s terminals and make sure they
are tight. If so, check the coil itself to see if it is open or shorted.
61
Motor Controller Current Sensor Fault: Drive or Lift Motor may be overheating. Let the
lift cool down. If that does not help, cycle power to reset the Motor controller. If the
problem persists, check the wiring and if OK, try replacing the Motor Controller.
62
Motor Controller Hardware Failsafe Fault: Cycle power. If that does not resolve the
issue check for noise sources. If still needed, try replacing the Motor Controller.
63
Motor Controller Motor Output fault: Check wiring first then cycle power. If needed
replace controller.
64
Motor Controller SRO Fault: Look at motor enable delay with the Dingli Scissor
Programmer, it may be too short. Make sure other Motor Controller parameters are
properly selected.
65
Motor Controller Throttle Fault: Check wiring. Make sure the correct throttle type is
selected in the Motor Controller.
66
Motor Controller Emergency Reverse Fault: Ensure that the Emergency Reverse
Check Parameter is off in the Motor Controller.
67
Motor Controller HPD Fault: Look at motor enable delay with the Dingli Scissor
Programmer, it may be too short. Make sure other Motor Controller parameters are
properly selected.
68
Low Voltage Fault: Check battery voltage and charge batteries if necessary. Check the
battery connections and tighten or clean. Check the voltage to the ECU and PCU.
69
High Neutral Current: The MC is sensing current in the motors when there should not
be. This could occur anytime the MC thinks the brakes are on and the motors are still
turning. This message sometimes comes just before other faults but should be ignored
in those cases.
70
Steering Input Out of Range: There is an inappropriate voltage at the steering input of
the ZAPI motor controller. The ZAPI may need to be “trained” for the three steering
voltages (on Differential Steered machines). Or the steering voltage from the ECU was
at some point outside of the range that was recorded during the “training” session.
Retrain the controller and/or check for fluctuating voltages due to lose wires, etc.
71
Motor Controller Main Contactor Fault: Check the connections to the main contactor.
Replace the contactor if necessary. Replace the Motor Controller if necessary.
72
Motor Controller Over Voltage Fault: Check battery voltage and make sure the battery
charger is not on. The cycle power to the lift. If that does not resolve the issue, try
replacing the Motor Controller.
73
Motor Controller Thermal Cutback Fault: Drive or Lift Motor may be overheating. Let the
lift cool down. If that does not help cycle power to reset the Motor controller. If that
doesn’t resolve the issue, replace the Motor Controller.
74
Motor Controller Motor Fault: Check connections to the motors. Cycle power to the lift
and if that does not resolve the issue, replace the Motor Controller.
75
Motor Controller Pump Motor Fault: Check connections to the Pump Motor. Cycle
power to the lift and if that does not resolve the issue, replace the Motor Controller.
