A constant uninterrupted power supply enables more sensitive adjustments Powering the unit on and off causes it to recalibrate during which time metal will not be detected When welding do not use the control panel mounting surface as a ground Mechanical Do Not use conductive Anti Static belt material Non conductive belt material is preferred When splicing belts use a Finger over Finger splice for best results Ensure all surfaces are clean and free of debris at the splice Vibration less installation of the detector coil except VT Higher sensitivities can be attained and maintained if the operating conditions are optimal Ensure the coil is mounted to a structure that is stationery at all times Eliminate loose metal to metal connections near or within the detection field Intermittent metal to metal contacts from such things as roller axis loose bolted connections or broken welds can cause the metal detector to false trip especially on the higher sensitivity settings Vibration less installation of the Control Panel Mount the control panel on a vibration free surface Vibration can cause premature electronic compo nent 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 re lief connections In addition to this we recommend t
