The „Push" command
In the operational state of pushing, the state of the light barrier attached directly to the door drive is
not observed and the closing speed is lowered. The commands „Push" and „Door closing" must be
present simultaneously.
Emergency release
If the door is closed, the emergency release is possible under following conditions:
when the door is in a standstill,
•
no commands from the elevator control system exist, and
•
no service button of the door drive was pressed.
•
When the door was determined to be open byb more than 20 increments (more than 14 mm) from
the "Door closed position", the door recognizes this as emergency release and disconnects the
automatic "Door closing" command.
The force required to open the door is smaller than 300 N.
!
Light barrier
A voltage ranging from 18 to 27V DC at the light barrier input is interpreted as interruption of the
light ray of the light barrier. This voltage is measured against 24 V GND.
In case of closing door, interruption of the light barrier results in the closing motion being interrutped
and as long as a light barrier command is present, a slow, opening motion is executed.
