9.4.3 Automatic closure (ZLA)
The open barrier closes automatically after the programmed ‘stay open time’ has elapsed. An earlier
closing of the barrier is possible by BT or BTZ. Is a stop signal given during the stay open time, then
the automatic closure is blocked and is only released again by a new signal. BTA1, BZA2, or LS keep
the barrier in the end-position ‘open’ even after the stay open time has elapsed. The barrier closes
immediately when a signal BTA1, BTA2, or LS is removed.
S4 off: No automatic closure
S4 on:
The barrier closes after the time which was saved during the
setup (0s up to 300s).
9.4.4 Reversal on hitting obstacles (REV)
When learning the running time during the setup the torque power for the reversing on obstruction is
determined. When the barrier boom hits an obstacle during closing and blocks, the controller stops the
movement or gives an ‘open’ signal.
S5 off:
The closing boom stops when it hits an obstacle and re-
opens immediately.
S5 on:
The closing boom stops when it hits an obstacle and only
moves when a new signal is received.
9.4.5 Counting (ZÄHL)
The signals ‘open’ and ‘close’ are counted by the controller.
S6 off:
No counting. The barrier closes after one signal to close,
even after two signals to open.
S6 on:
Counting is activated. The barrier closes after two signals to
close if there were two consecutive opening signals.
9.4.6 Reversal during opening (SZ)
When a ‘close’ signal is received during opening, the barrier will either open completely and then close
or the barrier closes immediately.
S7 off:
The barrier always opens completely before reacting to a
signal to close.
S7 on:
The opening barrier reverses immediately when it receives a
signal to close.
9.4.7 Automatic closure by photo-cell (LSA)
The photo-cell always gives a signal to close, when the obstacle is not longer present.
S8 off:
Automatic closure by photo-cell is not activated. The closing
function by loop B3/2 is not applicable.
S8 on: When an obstacle is not longer present the barrier closes.
9.4.8 Photo-cell test (LSTST)
Before each closing of the barrier, the photo-cells may be tested.
S9 off: Photo-cell test is not activated.
S9 on:
A photo-cell test occurs before each closing.
Attention: The photo-cell test has to be learnt when
programming the controller.
9.5 Photo-cell test
Before the closing of the barrier, the photo-cells may be tested. The photo-cell test consists of two
parts.
Part one: The transmitter is taken off the power supply and then the receiver has to report an obstacle
(within max. 2.5 seconds).
Part two: The transmitter is connected to the power supply again and then the receiver has to report
that no obstacle is present.
