The motor reports an overvoltage
fault.
Power being supplied to the
motor is above +42V DC. See
Overvoltage Fault on page 328.
The fault clears once the power
bus drops below +38V DC.
Verify the voltage output from the
power supply.
Verify the voltage at the motor.
Reduce power cable resistance
between motors that share a com-
mon +36V DC power supply.
Increase the spacing between
vehicles on motors that share a
common +36V DC power supply.
Reset of switch and paths that are
associated with the switch fails
when propulsion power is turned
off.
Propulsion power is required for
homing the flipper on the switch
during a Reset.
1. Allow the reset to fail on the
first try with the propulsion
power disabled.
2. Enable the propulsion power
(no vehicles move because
there are no vehicle records).
3. Issue a reset to the paths that
failed so they can complete
including the homing of the
flipper on the switch.
