Also check:

The ProScan sensor and other components for any damage that may have occurred during
shipping.

To make sure the sapphire lens is clean and undamaged. (If the lens needs to be cleaned, clean
it gently with a mild soap solution and a soft, clean cloth.)

The sensor’s electrical connector; it should easily mate with the connector pins on the sensor
body.

To make sure the threaded collar allows a snug, secure fit when fully engaged.
Electrical Connections
ProScan has a 5-pin electrical connector. The electrical connection scheme is shown in Figure 9, page 20.
If you purchased the molded, NEMA-6 electrical connector and cable from AW Gear Meters, simply
connect the cable as provided.
If you are using the Hirschmann connector (Part Number 932 878-100 ELST 512 PG9 ( www.hirschmann-
usa.com ) and need to make a cable connection, please read the following steps.
The most common wiring scheme for ProScan is a 3-wire connection:

Pin 2 is the mA output

Pin 3 is the 12 to 24 VDC power supply

Pin 4 is the ground (negative side of the supply).
A 4-wire connection can also be used to connect ProScan. In this wiring scheme, connect

Pin 1 (the negative side of the mA output)

Pin 2 (positive side of the mA output)

Pin 3 (12 to 24 VDC power supply)

Pin 4 (ground).
Pin 1 is the negative side of the mA output and is connected internally to Pin 4. This makes it more
convenient if you want to make a 4-wire connection as shown in Figure 1, page 8.
Pin 5, located in the center of the connector, is not used.
Once you make the connections inside the electrical connector, tighten the threaded cord grip on the
connector. This helps keep moisture from entering.
