Multiple Pulses on Origin (D-Series)

Possible causes

The sensor is receiving dual pulses from the origin magnet due to one of the following causes:

• Sensor positioned too far from the origin magnet

• Sensor and origin manget positioned at different heights

• Incorrect orientation of magnet inside enclosure

• More than one magnet on gate

• Incorrect orientation of origin magnet

• Magnetised item on rack

• Incorrect orientation of the electric motor is causing induction

• Missing pins on origin enclosure

• Faulty harness

• Faulty origin sensor

Solutions

• Ensure that the sensor is as close as possible to the origin magnet – ideally the gap should be approximately 13mm.

• Sensor and origin magnet should be positioned at the same height

• Ensure that there is only one magnet on the gate

• Ensure that there are no items such as metal bars on the rack that could have become magnetised

• Orientate the electrical motor so that the wires are facing away from the controller

• Replace faulty origin sensor

• Open sensor enclosure and correct orientation of internal magnet
