3-1. Installing the Detector Unit

• Select an earthed location for the mounting surface of the detector unit and secure
• Tighten the screws with a tightening torque of 1.4 to 1.8 N•m.
• If the detector unit is installed in a location that is not earthed, connect the detector
• Insert the output connector until it clicks into place.
• Do not connect or disconnect the output connector with detector during the power is

3-2. Resolution and Scale Output Signals
