Sensing Edge Switch Installation
Figure 6
shows an example of a typical sensing edge installation.
Right hand side is shown but Left hand is a mirror image of this.
1) Install junction box 12” above the center of the door opening
on same side as sensing switch.(A)
2) Secure one end of cord to junction box (A) using a cable
clamp.
3) Secure other end of cord (straight or coiled) to sensing edge
switch enclosure using a cable clamp. (B)
4) Connect wires of cord to sensing edge switch using wire nuts
or other suitable wire connectors.
5) Run 2 wire cable from the junction box (A) to the enclosure
junction box (C).
6) Join wires from switch using wire nuts or other suitable wire
connectors.
7) Manually Operate the door to make certain cord is free to
travel and does not become snared during door opening or
closing.
WARNING:
Actuating the operator using constant contact on the CLOSE
button will override non-functioning external reversing devices, including sensing edges.
AVERTISSEMENT:
L'activation de l'opérateur avec un contact
constant sur le bouton FERMER annulera les dispositifs de renversement externes non
fonctionnels, y compris les systèmes de détection des bords.
