• Install physical End stops in order to induce the stall needed to stop the motor
• Ensure that the harness is connected on both the controller and DOSS side
• Check for evidence of oil on the encoder
• Remove the DOSS and carrier so that the encoder wheel is clearly visible
• Disengage the gearbox
• Place your finger on the wheel
• Move the gate a metre or so in both directions
• Check your finger for oil
• Place an endstop approximately 100mm before the fully closed position and perform setup procedure
• Disconnect the motor wires from the controller and place them directly on the battery terminals to check whether the motor runs. If not, replace the electric motor.
