Installation
3.4 Optical Alignment
After the electrical connections are made, power up the emitter
and receiver. Verify that input power is present to both emitter
and receiver; the emitter Status indicator and the receiver Status
LED should be ON green. If the receiver Status LED is on red
(and a “c” appears on the 3-digit display), refer to Section 4.5.
NOTE: At power-up, all Zone indicators are tested (flash
red), then the number of blocked beams is displayed.
Observe the receiver indicators (see table below).
Optimize Alignment and Maximize Excess Gain
Verify that the emitter and receiver are pointed squarely at
each other. A straightedge (e.g., a level) can help determine the
direction the sensor is facing (see Figure 3-7).
Slightly loosen the sensor mounting screws and rotate one
sensor to the left and right, noting the positions where the
receiver Zone indicators turn from green to red; repeat with the
other sensor. Center each sensor between the noted positions
and tighten the end cap mounting screws, making sure to
maintain the positioning. The sensor windows should directly
face each other.
Once optimum optical alignment is verified, proceed to
configuration, via the remote teach wire, the receiver interface,
or the PC interface (Section 1.5, 4.2, or 5.3) and complete the
electronic alignment. This further alignment step adjusts the
emitted light level of each beam for the application, to maximize
sensing performance.
