2-074 M4 Vacuum Motor Overload Trip
2-075 M5 Vacuum Motor Overload Trip
Description M5 Vacuum Motor Overload
Setting
Conditions
The power module has detected current above 70 amps for
more than 5 seconds in the vacuum motor, but less than a
short circuit amperage.
When Monitored
Always
Possible Causes Failing vacuum motor
Initial Action Replace the vacuum motor
Troubleshooting Steps
Note that an obstruction in the suction hose will actually reduce the motor amperage, not increase it. So
that is not a likely cause.
2-076 M6 Squeegee Act Mtr Stall
Description M6 squeegee lift 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
• Improper actuator adjustment
• Failing actuator
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.
2-077 M7 Deck Act Mtr Stall
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
• Improper deck actuator adjustment
• Failing actuator
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.
