(Fig. 12.4) Door wings stop against mechanical stops
and invert in the event of obstacle detection.
Set an operatinJ time 2-3 s Jreater than the effective
time taNen b\ the door winJs (TMMAX) and connect
the closinJ proximit\ switch N.O. contacts to termi-
nals 0-11-12, positioninJ the proximit\ switches 2-3
s ahead of the mechanical stop.
In this con¿Juration, each door winJ stops aJainst its
respective mechanical closinJ and openinJ stop.
In the event of obstacle detection while openinJ,
onl\ the door winJ that detects the obstacle stops,
performinJ a disenJaJement operation.
In the event of obstacle detection durinJ closinJ and
before the activation of the proximit\ switch, the door
winJs reopen; after the activation of the proximit\
switch, the door winJs stop aJainst the obstacle.
(Fig. 12.5) Door wings stop against the limit
switches when opening and against the mechani-
cal stops when closing, and invert in the event of
obstacle detection.
Set an operatinJ time 2-3 s lonJer than the effective
time taNen b\ the door winJs (TMMAX), connect
the closinJ proximit\ switches to terminals 0-11-12
and set them 2-3 s earlier than the mechanical stops.
Connect the N.C. openinJ limit switch in series to
the openinJ phase of each motor.
In this con¿Juration, each win
J stops on its closinJ
mechanical stop and durinJ openinJ when the rela-
tive limit switches operate.
DurinJ openinJ operation, in the event of obstacle
detection, the winJ stops and releases.
DurinJ closinJ operation, in the event of obstacle
detection before both the closinJ limit switches have
been triJJered, both winJs reopen.
After each limit switch has been triJJered the cor-
respondinJ winJ stops on the closinJ mechanical
stop.
