2. Turn off the power to the crane.
3. Disconnect the sensor cable from the conditioning box.
4. Loosen the sensor retaining nut.

Swing Sensor Installation
1. Insert the threaded end of the sensor into the sensor port of the swing drive and screw it in until
the end of the sensor contacts the gear inside the swing drive housing. Do not force the sensor
any farther past this point.
2. Note the location of the index notch on the sensor. Rotate the sensor counterclockwise a ½
turn. (Illustrations on next page.)
3. Note the position of the index notch on the sensor and continue to rotate counterclockwise until
the index notch reaches the ‘three o’clock’ or ‘nine o’clock’ position.
4. If the initial 180° turn puts the index notch on the ‘three o’clock’ or ‘nine o’clock’ position,
continue to rotate counterclockwise until the next ‘three o’clock’ or ‘nine o’clock’ position is
reached.
5. For calibration instructions, refer to Swing Sensor Setup .
