The pedestrian command starts door opening, which lasts 1/3
of the work time set by means of the trimmer.
The door open indicator lamp notifies the user of the door status.
door closed - lamp off.
door in opening phase - slow flashing lamp.
door open - lamp lit.
door in closing phase - fast flashing lamp.
During the programming phase, it acts as an indicator light, and
at the end of programming returns to its original function
(vers.CT-1A).
The photocell command ensures that on interruption of the light
beam, all controls are inhibited.
During the opening phase, if the beam is interrupted, the door
completes travel to the normal pause position.
During the pause phase, if the beam is interrupted, the door
remains in this status until the beam is restored. When the beam
is restored, the door remains in pause status for a brief interval
(1/4 of the set time) and then closes. During the closing phase,
if the beam is interrupted, the door changes to the opening
phase.
Thrust is activated on opening and closing setting the maximum
force for 1.5 sec. to then return to the set power of the
autotransformer.
Working time range from 2 sec. to 60 sec. (with extension fitted,
the range is extended from 0 sec. to 120 sec.). The adjustment
trimmer to facilitate brief time settings on door movements has
an exponential range (more gradual at the start of the trimmer
range and less at the end).
Pause time range from 2 sec. to 180 sec.
N.B. During opening, if the photocell beam is interrupted, the
pause time is reduced to 1/4 of the set time.
The courtesy lamp uses the same relay as the flashing unit, and
extends operation time if selected for a fixed interval of 3 min.
