1. Drive the pan axis to the centre position of the required sweep angle & locate the pan preset
potentiometer as shown in fig.1.
2. Measure the resistance between pin 1 (0V return) &
preset connector.
3. Turn the clutch adjuster on the pan potentiometer (fig.1) to achieve a reading of 500 Ohms to
centre the Potentiometer.
4. Repeat the procedure for the tilt axis measuring the tilt potentiometer resistance between
pins 1 & 2 on the preset connector.
To replace a faulty potentiometer remove the fixing screws (2) (shown on fig.2) and remove the
assembly. Release the grub screw secuing the clutch assembly (4). Undo the nut (3) to remove the
