Mount the control panel on a vibration free surface Vibration can cause premature electronic component failure Avoid cable whiplash On VT Vibratory Conveyor installations use the supplied cable clamps and tie wraps to secure the cables to the metal detector housing Doing so will avoid whip lash at the transmit receive box strain relief connections In addition to this we recommend that you loop the cables as they exit the conduit These loops will then flex as the conveyor cycles It is also advisable to follow this procedure on belt conveyor installations Do Not touch the sensor coil surface of the detector Mechanical contacts may cause detection errors Keep the sensing surface free of debris Mount the FLAT PLATE type coils as close as possible to the underside of the vibrating conveyor or belt conveyor The closer the coil to the product being conveyed the greater the sensitivity Do not allow material to build up on the sensing face so that it touches the conveyor pan Doing so creates a closed conductive loop and the metal detector will false trip Isolate rollers on belt and driven roll conveyors On belt and roller conveyor applications where a roller is less than 24 610mm from the centerline of the detector the roller must be isolated on one side to avoid the possible effect of errant static charges Use UHMW shim beneath the bearing and nylon washers or some other non conductive material beneath the bolt head an
