Safety edge (de)activation of main closing edge
•
OBSTACLE DETECTION:
If the contact edge of the main closing edge is triggered,
an opening movement is effected for approx. 1s, then
the barrier stops.
That means: the barrier safety contact edge has to react on an obstacle during closing movement.
The connection has to be made on terminals 50/52.
Example:

8,2kΩ final resistance

Important
•
During the initial learning phase of the barrier the contact edge should not be triggered. This would lead to an
error message.

Safety
ACTIVE:
to be selected if the contact edge (8,2kOhm) of main closing edge should be evaluated.
NOT ACTIVE:
to be selected if the contact edge (8,2kOhm) of main closing edge should not
be evaluated.

Safety
Reverse during closing:
a
n interruption of the photocell/induction loop during closing makes the barrier reverse
(open). In automatic mode the barrier closes as soon as the pause time has run out. In impulse operation another
closing command has to be actuated.
Stop during closing, then close:
an interruption of the photocell beam or induction loop during closing makes the
motor stop as long as the photocell/loop stays interrupted. After release of the photocell, the barrier closes.
PHC/ISD-Photocell/induction loop with pause time
Safety
no influence:
the photocell/induction loop doesn’t have any influence on the pause time in automatic mode.
Immediate close after opening:
If the photocell is interrupted during the opening movement, the barrier starts closing
as soon as it reached the open end position.
PHC-Test
Safety
active:
photocell self-test is executed with an opening impulse (switch, button) in gate position „closed“.
not active:
photocell self-test is not executed.
Attention
•
The photocell self-test can only be deactivated by selecting „not active“.
•
The deactivation of the self-test function is only permitted if the safety installations correspond to the
category 3 !
