Nilfisk-Advance Advance SC5000 Service Manual

55Service Manual – SC5000 04 - Control System
2-031 M1 Scrub Motor Overload
2-032 M2 Scrub Motor Overload
Description M1 or M2 Scrub Motor Overload
Setting
Conditions
The brush motor uses M1 or M2 outputs. The power module
detected current above 70 amps to the brush 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 scrub deck for causes of locked rotor, such as debris wrapped around the shaft or failed
output bearings. If the output is not locked, replace the brush motor.
2-033 M3 Sweep Motor Overload
Description M3 Side Sweep Motor Overload
Setting
Conditions
The side sweep motor uses the M3 output. The power module
detected current above 70 amps to the side sweep 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 side sweep for causes of locked rotor, such as debris wrapped around the shaft or failed
output bearings. If the output is not locked, replace the motor.
2-034 M4 Vacuum Motor 1 Overload
2-035 M5 Vacuum Motor 2 Overload
Description M4 or M5 Vacuum Motor Overload
Setting
Conditions
The power module has detected current above 70 amps in the
vacuum 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 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.
