Assembly
Please clean the conveyor belt (of belt conveyors) regularly.
Metal impurities cause fault detections. Please make sure the belt runs centrically on the rollers and nothing
rubs on the belt.
Pay attention to an electrical insulated installation.
The coil feet of the detector provide for electrical isolation. Please do not remove them.
Do not use anti-electrostatic (or electrically conductive) belt material.
Anti-electrostatic belts are conductive and cause an effect similar to metal in the metal detector.
Depending on the relevant application, a conveyor belt appropriate for the metal detector must be chosen.
The conveyor belt should have a so-called finger coupling. Furthermore, glue containing metal particles
must not be used for connecting the belt.
Do not touch the sensor/coil surface of the detector.
Mechanical contacts may cause detection errors. Keep the surface free of debris.
The frame must be manufactured with appropriate stability.
Loose attached parts, in particular loose transverse connecting parts such as bracing struts, bolted discharge
plates, cover plates etc. can cause considerable interference. Screwed connections should be dispensed with
entirely in this area if possible – welding is better. Insulate the parts on one side wherever screwed
connections are absolutely necessary.
Power rolls, deflection rollers and snub pulleys are also possible sources of interference, as the
electrical contact is submitted to large variations caused by damaged or bad bearings.
The same applies to swivelling belt strippers. These parts should always be insulated on one side.
Please
note:
Bridging bad contacts with earth band or wire will
not help!

Introduction
General notes on metal detection
When welding at the construction where the metal detector is mounted, disconnect the metal detector
from the power supply and do not use the control panel mounting surface as a ground.
Welding in the surroundings of the detector will trigger faults.
