Rockwell Automation 40CA4 Miniature End View Transmitted Beam Control - Manual (Page 2)

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

WIRING
All external wiring should conform to the National Electric Code
and applicable local codes. See wiring diagrams for external connec-
tions. For maximum electric shielding, rigid conduit is recommended
for extensions of scanner wiring. DO NOT RUN PHOTODETEC-
TOR 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 clock-
wise. 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 verti-
cal 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.
