Installing the metal
detector
piece of machinery as this could lead to vibration being transmitted to the head, resulting
in spurious triggering.
• When the height is correct, lock the wheels (if fitted).
• If the conveyor is fitted with feet, you are recommended to apply silicone sealant around
the feet and floor.
Connecting electrical supplies
The standard metal detector conveyor is fitted with a starter isolator and a 24V ac control
circuit. The supply voltage for the conveyor is indicated on the identification plate that is
mounted on the frame.
• Switch the isolator to the 'Off' position then unlock and open the door.
The following illustration shows the isolator inside a typical electrical services box:

T1 T2 T3
• Remove the plastic terminal cover from the starter isolator.
• Cable entry is via the brass gland provided on the bottom rear face of the electrical
services box.
NOTE: Do not use rigid conduit of any type. Rigid conduit can lead to vibration being
transmitted to the head, resulting in spurious triggering.
• The supply to the conveyor must be either 5-core cable (3-core cable is suitable for single-
phase machines) fed through a flexible conduit or 5-core armoured cable. Insert the cable
through the gland.
• Split the cable inside the box and cut the wires to suitable lengths. The wires for the
phases, neutral, and earth are connected to terminals on the isolator switch.
