Installation/Setup Procedures
Mechanical Installation		Electrical Installation
For 1/2" models, use a 12A272 mounting clamp, or its equivalent, to securely mount the sensor. All other models have either #10 or 1/4" clearance holes, for mounting to bulkheads or brackets. Units should be mounted as far from metal as possible, and adjusted after they are mounted. As a general rule, sensors mounted side-by-side should be spaced a minimum of half the sensor diameter away from each other, and sensors mounted face-to-face should be spaced three times the sensor diameter away from each other.		Your sensor's electrical connections must agree with those shown in the corresponding wiring diagram above.
Setup Procedure
Apply power. With no target present, turn the adjustment potentiometer fully CW. This is the point of maximum sensitivity. Then, test for detectability. Use actual parts to test detection. Feed your parts through the center of the ring, where sensitivity is the least, to ensure consistency. To reduce sensitivity, turn the potentiometer CCW. Note: PE706 Models are dynamic (AC coupled) devices, which deliver high-sensitivity performance. They do, however, require a 1'/minute (.3 meters/minute) minimum movement of target materials.
