OPERATING DISTANCE SELECTION
The maximum operating distance is based on installing the control
in a relatively clean environment. Normal industrial environment actually ranges from moderately dusty to extremely dirty. Greater oper-
ating margin (excess gain) may be required, which can be obtained by
reducing the operating distance of the control. (optics should be
cleaned regularly.)

INSTALLATION
The control must be securely mounted on a firm, stable surface or
support. A mounting which is subject to excessive vibration or shifting may cause intermittent operation.

WIRING
All external wiring should conform to the National Electric Code
and applicable local codes. See wiring diagrams for external connections. For maximum electric shielding, rigid conduit is recommended
for extensions of scanner wiring. DO NOT RUN PHOTODETECTOR WIRES AND LINE VOLTAGES IN THE SAME CONDUIT.

ALIGNMENT
Set the amplifier to the light operate mode. Adjust the sensitivity
to the maximum setting, turning the sensitivity potentiometer clockwise. Aim the light source at the receiver until the alignment indicator
on the amplifier turns on.
To be certain that the beam is centered, sweep the receiver at the
light source in the horizontal plane and determine the position where
the alignment indicator turns on and then off. Do the same in the vertical plane. Set the beam halfway between both positions.
It may be necessary to reduce the sensitivity to a lower setting for
transparent or translucent materials or to detect objects smaller that
the effective beam.
