2. DOOR OPERATOR LIMIT SWITCH STATE
Refer to Figure 3-3. The limit switch actuation diagram shows the state of all limit switches as the doors go
from fully closed to fully open. The solid (?) line indicates the normally closed circuit is active, while the two
thin lines ( ) indicate the normally open circuit is active. The dotted lines (????) are used to show the switch
states beyond the normal travel boundaries of the door. This is useful in showing the operation of switches that
change state at the boundary point.
3. WIRING DIAGRAM
