2.3 Angle Sensor Installation
Warning! The angle sensor must be installed such that the antenna is not in contact with
a metal surface or object (boom, jib, wire, chain etc.). Such contact will interfere with ra-
dio communication between the angle sensor and the display unit.
Warning! When welding the metal lugs to the boom the angle sensor must be kept well
away from the weld site and any touching metal objects.
The angle sensor is pre-calibrated at the factory; for correct installation it must be positioned
carefully, then zeroed. The bracket has two boltholes, one of which is a curved slot for fine ad-
justment. See the diagrams below for correct orientation. The angle sensor should be mounted
on the left side of the boom (as viewed from the cab) with the indicator light towards the boom
tip.
