Install The Protector System - Chamberlain ATS2113X 1/2 HP Installation Manual

INSTALLATION STEP 10

Install The Protector System

The safety reversing sensor must be connected and aligned
correctly before the door operator will move in the down
direction.
IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
When properly connected and aligned, the sensor will detect
an obstacle in the path of its electronic beam. The sending
sensor transmits an invisible light beam to the receiving
sensor. If an obstruction breaks the light beam while the door
is closing, the door will stop and reverse to full open position,
and the operator lights will fl ash 10 times.
The units must be installed inside the building so that the
sending and receiving sensors face each other across the
door, no more than 6" (15 cm) above the fl oor. Either can be
installed on the left or right of the door as long as the sun
never shines directly into the receiving sensor.

Protection Area
Be sure power is NOT connected to the door operator
BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a closing
door:
• Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above the fl oor.
If it is necessary to mount the units on the wall, the brackets
must be securely fastened to a solid surface such as the wall
framing. If installing in masonry construction, add a piece of
wood at each location to avoid drilling extra holes in masonry
if repositioning is necessary.
The invisible light beam path must be unobstructed. No part
of the door (or door tracks, springs, hinges, rollers or other
hardware) may interrupt the beam while the door is closing.
