5.1. ARRIHEADs
Danger
Whichever ARRIHEAD is used, it should NEVER be operated upside down, as that would
damage the head.
Danger
Disconnect the System from the power supply or battery when assembling, disassembling
or servicing the equipment.
The ARRIMOTION system can work with a regular ARRIHEAD-1, a regular ARRIHEAD-2 or with an
Encoded ARRIHEAD-2.
Exchanging the Position Pin
On the pan and tilt gear boxes of all ARRIHEADs, one screw must be exchanged for a special pin
with a hex driver head (use a 2.5 mm hex driver). These special pins come with the CHM-1 motors.
Some ARRIHEADs already have pins with slotted heads; those must also be replaced with the pins
with the hex driver heads.

Encoded ARRIHEAD-2
The Encoded ARRIHEAD-2 is equipped with position sensors on the main pan gear and on the left
rail of the tilt mechanism and there are three sensors for the three locks.
• Encoders in the pan and tilt mechanisms provide higher precision in position detection (=easier
and more accurate homing).
• Automatic lock detection
