Why is the scrub motor of my Nilfisk-Advance EcoFlex BR 1100 S overloading?
If the scrub motor on your Nilfisk-Advance Scrubber is overloading, consider the following possible solutions: 1. Check for any binding in the rotation of the brushes and ensure the brush deck lift actuator is operating correctly. 2. Inspect the negative supply cable at the brush motor for wiring issues, and also check the small BRN current sense wire in the harness and A2 pin J2-2. 3. Look for any short circuits in the brush motor or its wiring. If you have a cylindrical model, verify there is no excessive belt tension and check the condition of the idler bearing. Note that some models use one, two, or three scrub motors.
How to troubleshoot squeegee actuator overload on Nilfisk-Advance EcoFlex BR 1100 S Scrubber?
To troubleshoot a squeegee actuator overload on your Nilfisk-Advance Scrubber, follow these steps: 1. Check for any binding or frozen squeegee lift linkage and excessive weight on the squeegee mount. 2. Inspect the actuator motor and wiring for a short circuit, and repair or replace if necessary. To test the actuator, disconnect the motor plug and attach the actuator power cord adapter (p/n 56407502) and perform an amp draw test. Compare readings to the current load specifications. Normal current load is 1-2 amps. Max current load is 6 amps. Max current with no load is 1.4 amps.
What causes the scrub deck actuator to overload in my Nilfisk-Advance EcoFlex BR 1100 S?
The scrub deck actuator in your Nilfisk-Advance Scrubber might be overloading due to: 1. Binding or a frozen brush lift linkage, or excessive weight on the brush deck. 2. A short circuit in the actuator motor and wiring. Repair or replace the faulty components. To test the actuator, disconnect the motor plug and attach the actuator power cord adapter (p/n 56407502) and perform an amp draw test. Compare readings to the current load specifications. Normal current load is 1-3 amps. Max current load is 6 amps. Max current with no load is 1.4 amps.
What to do if the scrub deck actuator is open on my Nilfisk-Advance EcoFlex BR 1100 S Scrubber?
If the scrub deck actuator is open on your Nilfisk-Advance Scrubber, you can try the following: 1. Check for disconnected lift actuator wiring. 2. Check for an open circuit in the motor wiring or for a defective motor. 3. Check for output voltage from the A2 control board assembly at the actuator wiring plug. It should be 36 volts. If 0 Volts, check the A2 control board assembly.
What should I do if there is L1 solution solenoid open on my Nilfisk-Advance EcoFlex BR 1100 S Scrubber?
If there is an L1 solution solenoid open on your Nilfisk-Advance Scrubber, you can try the following: 1. Check for an open circuit in the L1 coil and wiring (wire colors VIO and YEL/GRN). 2. Test for 36V at the L1 coil. If 0 Volts, check the A2 control board assembly.
What causes the scrub deck sense R2 resistor fault in Nilfisk-Advance EcoFlex BR 1100 S Scrubber?
A fault will occur if the scrub deck sensor resistor is unplugged or damaged. Check the resistor wiring for an open and substitute a new resistor and test scrub deck for correct operation. Note that there are four different resistor values used on the different deck types. See the electrical diagram decal for the correct specification for the resistor to replace.
What should I do if the solution control pump is open on my Nilfisk-Advance EcoFlex BR 1100 S Scrubber?
If the solution control pump is open on your Nilfisk-Advance Scrubber, you can try the following: 1. Check for an open circuit in the M12 pump motor and wiring (wire colors VIO and BLU/ORN). 2. Test for 36V at the pump motor. If 0 Volts, check the A2 control board assembly.
How to resolve center brush motor contactor coil overload in Nilfisk-Advance Scrubber?
If you're experiencing a center brush motor contactor coil overload on your Nilfisk-Advance Scrubber, try the following: 1. Check for a K3 coil wiring problem or a short circuit (wire colors VIO and WHT/VIO). 2. Check the coil resistance. If the resistance is below 75 ohms, replace the coil. Contactor K3 is for the center motor on three-motor decks. K3 is for the left motor on two-motor decks.
What to do if there is a K5 auxiliary contactor coil overload on my Nilfisk-Advance Scrubber?
If you have a K5 auxiliary contactor coil overload on your Nilfisk-Advance Scrubber, here’s what you should do: 1. Check for a K5 coil wiring problem or short circuit (wire colors YEL/BRN & BLK/ORN). 2. Check the coil resistance. If the resistance is below 80 ohms, replace the contactor. The nominal coil resistance is 100 ohms.
