INSTALLATION

TERMINAL FENCE

LOCATION

For optimal batch detection, KAM CONTROLS recommends that you install the in-station OFD™ sensor at the
first accessible pipeline location inside the terminal fence-line — upstream of the interface cut valve(s). This al­lows the operator ample time to open/close the cut valves prior to the arrival of the product interface.

KAM CONTROLS also strongly recommends that you utilize a preview (or out-station) OFD™ sensor. This lets the
operator decide how to optimize each batch cut prior to actually making the batch cut at the in-station and gives
the operator more confidence in their decisions as well as the time to identify and resolve any issues that may
arise during a critical interface.

PRIOR TO INSTALLATION

Remove all the protective packaging materials including the red cap placed at the tip of the sensor probe. En­sure that the OFD™ sensor was not damaged during transit.

CAUTION: Do not stand the OFD™ sensor on the probe end or allow the probe to hit the ground or any hard
surface under any circumstances. This will damage the lens, and the OFD™ sensor will not work properly.
