8.1.1. Sequence P1: Learning of the running distance
When sequence P1 has been activated, it has to be selected first between gates with one
(1F) or with two (2F) wings using button BT. Then confirm the selection with button LERN.

is displayed. The gate wings now can be operated by dead man’s motion using
buttons BT or BTG to adjust the internal mechanical end stoppers (when using openers
like TERRA or ZENIT). BT is used for the main wing and BTG for the pedestrian wing. The
first direction is always OPEN.
Attention! During learning the safety devices may act different from the
regular operation. Please ensure that no people are in the danger area during
learning.
After adjusting the end stoppers, push the button LERN to continue: The controller tests
the safety contact strips and the photo-cells. It learns the type of the safety contact strips
(8.2 k
Ω
) and the number of connected photo-cells. Only when this photo-cell testing was
successful, additional photo-cell tests can be carried out during future operation.
Gates with one wing:
During learning of the running distance the wing opens first and then closes.
Gates with two wings:
During learning of the running distance the pedestrian wing opens, the main wing opens,
the main wing closes and pedestrian wing closes.
In both cases the wings move until they hit the stoppers at the closed position. During the
learning of the running distance the pressure relief of the electromechanical bolt is not in
function. The electromechanical bolt is being activated during each wing movement.
After the learning of the running distance, returning to the main sequence follows
automatically.
Remark:
After adjustment of the end stoppers, the wings should not be in either
end position but at least 50cm before. The first movement is into direction open.
