Battery Drain Alarm (Lithium)
Disable All
Motion
Total Voltage Low Fault 2: Check battery voltage
and charge if necessary. Check the battery
connections and tight or clean. Check the voltage
to the ECU and PCU.
69
High Neutral Current Fault (Zapi
Only)
Disable Lifting
and Driving
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
Steer Input Out of Range (Zapi
Only)
Disable Lifting
and Driving
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. Re-train
the ZAPI and/or check for fluctuating voltages due
to lose wires, etc.
71
Motor Controller Main Contactor
Fault
Disable Lifting
and Driving
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
Disable Lifting
and Driving
Motor Controller Over Voltage Fault. Check
battery voltage and make sure the battery charger
is not on. Then cycle power to the lift. If that does
not resolve the issue, try replacing the Motor
Controller.
73
Motor Controller Thermal
Cutback Fault
Disable Lifting
and Driving
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 Over Heat Fault
Disable Lifting
and Driving
Motor Controller Motor Fault: Check connections
to the motors. Cycle power to the lift and if that
