The reliable performance of light screen systems requires careful alignment and
secure mounting. The 2-part, 3-axis mounting brackets on page 5 are highly
recommended. Mounting locations should be as free from vibration as possible. If
vibration is unavoidable, mount the emitter and receiver to vibrate together; no high-
amplitude differential vibration is allowed.
Mount the emitter and receiver at their operating locations with their front panels
exactly parallel and opposite each other. (The row of transmitter LEDs should be
exactly parallel with and opposite to the row of receiver phototransistors.) This
constitutes optimal mechanical alignment.
Optimal mechanical alignment does not always result in perfect optical alignment, and
perfect optical alignment is absolutely necessary. When optical alignment is
satisfactory, and emitter/receiver vibration is at moderate or lower levels, the receiver
Alignment status indicator (see Figure 1) will be OFF and remain OFF whenever the
light screen is unobstructed.
Adjusting Optical Alignment
Beginning with perfect mechanical alignment, adjust optical alignment as described in
steps #1 through #5. The procedure assumes use of the SMBLS mounting bracket
shown in Figure 2. Only the position of the emitter will be adjusted.
1) Loosen the two bolts holding the two parts of the bracket together just enough to
2) With power applied to both the emitter and receiver, “tip” the entire bracket
3) Rotate the carriage bracket (to which the emitter is attached) slightly in both
4) Loosen the two mounting bolts that hold the emitter to the carriage bracket. Slide
5) Check for proper alignment by moving a pencil (or a similar object) along the 3.5"
Installation and Alignment
allow the upper (“carriage”) bracket, along with the emitter, to be rotated. Also,
slightly loosen the mounting bolts in the curved slots of the “base” bracket, which
will allow the bracket to be tipped from side to side.

receiver’s red Alignment indicator LED remains OFF. Secure the emitter midway
between the extremes by tightening the two bolts that lock the two parts of the
bracket together.

secure the emitter midway between the extremes. (NOTE: If the initial mechanical
alignment was inadequate, it may be necessary to repeatedly alternate tipping,
rotating, and sliding movements to attain perfect optical alignment.)

outputs should come ON while the pencil is anywhere within the sensing window.
When this is true, tighten all mounting hardware securely in position.
