above the fl oor level and as close as possible to the 
door opening, inside the garage. Remove shunt from 
P.E. connector (Fig. 16) and connect the wires from the 
P.E. wiring harness as per Fig. 17.
NOTE: The wiring diagram is for an Automatic 
Technology Transmitter/Receiver type P.E. beam: 
model: PE-2 (Order Code 90214) with Wiring Harness 
(Order Code 01900).
Make sure to align the beams correctly. Follow the 
manual supplied with the Photo Electric Beam.

manner in which it is installed might not give 
safety protection at all times. Check to make 
sure that the height of the beam and type 
used give maximum protection possible.
