Installation/Setup Procedures
Mechanical Installation		Electrical Installation
Use the sensor's two mounting holes, which are .187" ( 4.75 mm ) in diameter and spaced on 3.80" ( 96.52 mm ) centers, to fasten the sensor securely to a bulkhead or bracket. The remote sensing element must be constructed and secured in a way that prohibits movement of the element, with respect to ground or the object to be detected. Note : For new installations, you may require an optional 12A907 Triaxial Bulkhead Connector, to interface with your remote sensing element. As a general rule, remote 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 for Switched Output
The following procedures must be performed any time the dip switch settings are changed. The instruction label on the inside of the cover explains the dip switch settings. Apply power. With no target present, turn the adjustment potentiometer CW until an alarm condition exists ( Normally Open - LED is lit ). Then, turn the pot CCW until the alarm just resets. This is the point of maximum possible sensitivity; this is not the recommended operating point, however, as temperature fluctuations may cause false alarms or detection failures. For the optimum setting, put a target at the desired detection point and ensure that the switch is alarmed. Turn the pot CCW until the unit just resets, noting the number of turns to reset. Return CW half this number of turns. Note:   A minimum of  ¼  turn CW is recommended to ensure stable operation.
Setup Procedure for Analog Outputs
The following procedures must be performed any time the dip switch settings are changed. The instruction label on the inside of the cover explains the dip switch settings. Connect a DC voltmeter between the amplified analog 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.
