2-036 M6 Squeegee Act Mtr Overload
Description M6 Squeegee actuator motor overload.
Setting
Conditions
The power module has detected excessive current in the
squeegee lift actuator, but less than short circuit amperage.
When Monitored
Always
Possible Causes
Because the overcurrent condition has reached the maximum permissible amperage
of the power module, it is likely that the motor is in a locked-rotor condition, such as
the leadscrew nut being driven into the gear housing.
Initial Action Check the Squeegee Actuator Limit Adjustment described on page 204
Troubleshooting Steps
If the actuator is properly adjusted and no signs of binding are observed, replace the actuator.
2-037 M7 Deck Act Mtr Overload
Description M7 deck lift actuator motor overload.
Setting
Conditions
The power module has detected excessive current in the deck
lift actuator, but less than short circuit amperage.
When Monitored
Always
Possible Causes
Because the overcurrent condition has reached the maximum permissible amperage
of the power module, it is likely that the motor is in a locked-rotor condition, such as
the leadscrew nut being driven into the gear housing.
Initial Action Check the Lift Actuator Limit Adjustment described on page 181
Troubleshooting Steps
If the actuator is properly adjusted and no signs of binding are observed, replace the actuator.
2-038 M8 Option Pump Motor Overload
Description M8 Wash Pump Motor Overload
Setting
Conditions
The power module detected excessive current to the pump
motor, but less than a short circuit amperage.
When Monitored
Always
Possible Causes
Because the overcurrent condition has reached the maximum permissible amperage
of the power module, but not short-circuit level, it is likely that the motor is in a
locked-rotor condition.
Initial Action None
Troubleshooting Steps
Inspect the pump motor for causes of locked rotor. If the output is not locked, replace the motor.
