25 Limit Switches
There are three limit switches located within the horizontal member mechanism. See Diagram 25A. These
switches are attached to levers that contact the curtain.
The Home Switch
establishes the 'open'
reference position of the
door curtain. This creates
the zero reference
position, from which the
encoder counts the
position of the door.
The Safety Switch is a fail-
safe switch that stops the
curtain in the unlikely
event of malfunction of
the home switch.
The Leading Edge Switch is
a switch that stops the
curtain in the event of a
doorway obstruction.
