Characteristics of the ez-Wheel product

The range of autonomous wheels, ezW160 enable powerful electric drive to be installed quickly and easily.
ezW160 wheels are controlled by a wired interface connected directly to the back of the wheel casing. Many accessories are available for controlling the wheels in the ez-Wheel range.

First use

Charging the ez-Wheel

Wheels can be charged anytime as long as a mains connection is available (if necessary several times per day). It is not necessary to wait for the battery to be discharged.

If the charging system consists of an XLR remote charger connection:

  • Connect the XLR cable from the charger to the 5-pin on-board connector fitted to the application chassis.

If the charging system consists of an on-board charger (with the suffix /160),

  • Connect the charger socket directly to the mains.

Use a suitable charger.

Contact the dealer for more information on chargers.

The indicator light "BATTERY" on the wheel should be orange and flashing.
1 to 2 hours are required to charge the wheel fully.

When the wheel is charged, the indicator light "BATTERY" on the wheel is green and flashing.


  • Refer to the paragraph entitled: “Display” for more details about the indicator lights.


When the wheel is charged, disconnect the charger by pressing the lug on its XLR connector.
To disconnect the charger connector, press in the locking lug and pull the connector.
To put the wheel back into operation, disconnect the charger and switch the wheel on by pressing the ON/OFF switch.
Only use chargers approved by ez-Wheel. For further information on charging wheels contact the dealer.

First use of the ez-Wheel product

It is necessary to charge the wheels completely before using for the first time. (See: Charging the wheel).

Motor operation is controlled by the actuator accelerator.

  • To switch on the wheel: Press the ON/OFF switch situated at the back of the wheel or mounted remotely.

The wheel goes into sleep mode after a few minutes without movement on the actuator to conserve battery life.

  • To restart the system, press the ON/OFF switch; wake-up is immediate.


  • Make sure that the wheel is firmly located before switching it on.
  • Check the condition of the wheel: Press the ON/OFF button on the wheel label and check that the light "OK" is green.

( The light "BATTERY" indicates the level of charge of the battery. See "Display" appendix)
If the application has several wheels, repeat the operation for all the wheels.

  • Press the remote switch connected to the ezACxM-B/160 or ezACxM-BD/160 cables.
  • Check the display on the wheel, or the remote display if there is one.
  • Check forward and reverse operation with the actuator.

Precautions for use

If one of these steps does not take place as described refer to the “troubleshooting” paragraph or contact the dealer.
