Installation/Setup Procedures
Mechanical Installation Electrical Installation
Use a 12A272 mounting clamp, or its equivalent, to securely mount the sensor.

Multiple units must be spaced at least 25mm apart, laterally, and the sensing face of each unit must extend 25mm beyond any mounting bracket.

As a general rule, expanded sensing elements must be spaced a minimum of the sensor diameter away from each other.
      Your sensor's electrical connections must agree with those shown in the wiring diagram above.
Setup Procedure
Connect a DC voltmeter between the output lead of the sensor and ground.

With no target present, turn the adjustment potentiometer fully clockwise (CW). The voltmeter should read greater than 6 volts. Then, turn the pot counterclockwise (CCW) until the voltage drops to approximately 3 volts.

Place the intended target material in the sensing field and adjust for the desired voltage outputs, with respect to the variations you wish to monitor.
