-13 x 1-in. hex head cap 

screw, Eurodrive washer, and a split lock washer. 

2.

Install the FEIG encoder hub shaft end to the end of 
the encoder coupling shaft and tighten set screw.

NOTE: Use a low strength thread locker on set

screw.

 x 18 mm socket head cap screws

.

4.

Connect encoder cable to encoder. 

5.

Install plastic zip tie into socket head screw and 
secure the encoder cable. (See Figure 25.)

NOTE: The zip tie that is used in the securing of

the encoder cable is of special design. The
ribbed end inserts into the valley of the
socket head cap screw.

PHOTO EYE INSTALLATION

The disconnect must be in the “OFF” posi-
tion and properly locked and tagged before
performing the following procedure.

NOTE: The door is shipped with two sets of photo

eyes. One set monitors the back side of
the door. The other set monitors the front
side of the door. Each set consists of an
emitter module and a receiver module.

The photo eyes are provided as a safety
feature. With the photo eyes correctly
installed, interrupting either set of eyes as
the door is closing will reverse the direc-
tion of the door and hold it in the fully open
position until the interruption is removed.

Figure 26

NOTE: Locate the photo eyes on the wall adjacent

to the sides of the door. Each eye must be
installed 12–36 in. above the floor and as
close to the door as possible. They must
also be mounted directly across from each
other.(See Figure 27)

The photo eyes, their required wire
cables, and mounting brackets were
shipped in the small parts carton. You
must provide the hardware to install the
brackets on your particular wall. The photo
eyes provided MUST all be properly
installed. (See Figure 27.)
