## Overview 

The MULTI-BEAM Optical Edgeguide System is a unique sensor, used in pairs, to provide complete edge-guidance sensing and control. Each sensor consists of a special MULTI-BEAM scanner block, power block, and logic module. 

Each component is designed specifically for the edge-guiding function. The scanner block, which contains a modulated emitter and receiver, works together with the power block such that the emitter is gated "ON" only during positive half cycles of the 50/60Hz power, and the receiver is gated ON only during the negative half cycles. The opposing sensor operates the same way, except that it is wired with power leads L1 and L2 reversed from the way they are connected to the first sensor. As a result, the sensor A emitter will only operate the sensor B receiver, and vice-versa. This synchronization of the two sensors prevents unwanted crosstalk while permitting very high excess gain. 

The logic module includes both ON- and OFF-DELAY timing functions. The ON-DELAY ignores short-term nuisance signals, and the OFF-DELAY permits a controlled amount of timed correction. 

The logic modules have a LIGHT/DARK OPERATE programming jumper. Typically, the inboard receiver is programmed for LIGHT OPERATE, and the outboard receiver for DARK OPERATE. In this way, the web being guided is properly positioned in the "deadband" between the sensing beams when one beam is broken and the other is not. The spacing between the beams is fixed at 1/2 inch (12.5 mm) and this becomes the "deadband" for edgeguiding. If tighter control is desired, the two sensors may be mounted at an angle to the edge of the web such that the effective beam spacing is reduced to 1/2 inch times the cosine of the angle.

MULTI-BEAM Optical Edgeguide System 

The power block contains the same 3/4 amp solid-state switch as is used in standard MULTI-BEAM power block models PBA and PBB, which will operate most ac solenoids, relays, or programmable logic controllers (PLCs). The very high optical penetrating power (excess gain) plus rugged MULTIBEAM construction permits reliable control in harsh environments such as sawmills or power sanding machines where conventional photoelectrics could not survive the contamination levels. If necessary, optical penetrating power may be reduced by substituting model UC-D upper covers. 

## Install the Optical Edgeguide System 

1. Mount the sensors exactly parallel to each other with their lenses directly opposite each other (see Figure 1 on page 1). 

2. Verify the wiring according to the wiring diagram (see Wiring Diagrams on page 2). One sensor must be configured for dark operate (jumper installed) and the other must be configured to light operate (remove jumper) 

3. Perform the operation checkout procedure (using alignment indicator LEDs): 

   - Both beams unblocked: Both LEDs are on and one output is on 

   - One beam blocked: One LED is off and no output in on 

   - Both beams blocked: Both LEDs are off and the other output is on 

4. If necessary, decrease the SENSITIVITY (beneath lower cover; rotate control counterclockwise) to prevent "burn-through" when guiding non-metallic materials (and/or use model UC-D upper covers).
