Gate Stalled (D-Series)

Gate Stalled (D-Series)

Possible causes:
• The operator is encountering a fixed obstruction
• The operator is jammed into an Endstop
• The gearbox is disengaged (D5-Evo/D5-Evo only)
• Loose drive connection (battery or motor terminal)
• Oil in DOSS chamber
• Faulty DOSS
• Sticky motor brushes

Solutions:
• Ensure that the gate is running smoothly and that there is nothing physically obstructing the gate, e.g. dirt or stones on the rail, rack pressing down on the pinion, bad rack joints, etc.
• Connect the motor wires straight onto the battery to drive the gate in the opposite direction and release it from the Endstop
• Engage the gearbox by turning the thumbwheel anticlockwise (D5-Evo/D5-Evo Low-Voltage only)
• Ensure that drive connections (battery and motor wires) are secure
• Check for evidence of oil on the encoder by following the procedure below: (D5-Evo/D5-Evo Low-Voltage only)
- 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
- Replace faulty DOSS
• Arrange service with an authorised workshop

To reach the DOSS chip on a D5 EVO, you'll have to remove the cover of the motor. You'll find the DOSS positioned above the thumbwheel, directly in front of the red electronic motor.  For easy Identification, there is a warning sticker on the DOSS cylinder indicating "No oil allowed".
