Arm Positioning For Pull Units
Review the Installation Guide for Detex Low Energy Automatic Door Operator Control Module, P/N
104827 before proceeding. We have preset controls to approximate settings. Open the door to
90° (degrees). Turn the 3-way toggle switch, located at end of enclosure, to “HOLD” position.
The operator will activate and the motor output shaft will rotate 240° (degrees). Install the arm so
the forearm is rotated to 90° and parallel to door leaf and secure by tightening screw. While in the
full open position, apply the safety washer to the bottom of shaft.
With the door and gear motor in full open position, mark the forearm pin location for the end point of
travel and the pin depth on the door.
Turn the 3-way toggle switch to “OFF” position. At the closed position, mark the arm pin location
for the opposite endpoint of travel and for pin depth.
Center the track over the pin travel locations. Set the height of the track so that the pin maintains
clearance with the bottom of the track throughout the entire length of travel.
Mark the mounting holes and attach with the appropriate fasteners. Open the door and switch the
3-way toggle switch to the “HOLD” position. Install the track with the pin in the slide block, use the
supplied screws (two #14x1-1/4” TEK Screws).
