Neutral
APL-RT
Red signal, 230 V max. 60 W. The red light is on when the gate is closed and warning prior
opening is not active.
APL-GN
Green signal, 230 V max. 60 W. The green light is on when the gate is open and warning
prior closing is not active.
(N)
Neutral
WARN
Warning light 230 V max. 60 W. The warning light is on every time the gate moves and also
if a warning prior to moving is active.
The warning light can be used also as red if it’s desired that red turns off when the gate is
closed.

EXT-AUF
Transmission of the signal BA1 to a second control box (n.o.).
The relay EXT-AUF (max. 24V, 100mA) energises if BA1 is pressed, or the corresponding
remote button is used and falls off after about 1 second. The connection EXT-AUF can be
used to transmit the signal to a open-input to a second control box e.g. for a barrier.
-------
BA1
Button to open the gate (n.o.), the signal is transmitted to terminal EXT-AUF. The LED BA
lights if BA1 or the corresponding remote button is pressed. A permanent open signal is
possible.
BA2
Button to open the gate (n.o.), the signal is valid only for this controller. The LED BA lights
when BA2 is pressed. A permanent open signal is possible.
BZ
Button to close the gate (n.o.). The LED BZ lights when pressed. Delayed closing is possible
(see operating mode).
LS
Photo-cell (n.c.), or a jumper. The LED LS lights when the photo-cell is interrupted. The
controller can react in three different ways (see section 7.2.). The photo-cell can also be
connected to BS and used as a stop button.
NB
Toggle between day and night operating mode, works only when the optional timer card is
being used (see section 8.).
SLZ
Safety contact strips (n.c.) for direction “gate closed”, or a resistor (8,2k
Ω
). The LED SLZ
lights whenever the strips are activated. SLZ causes STOP and reversal for a short way.
SLA
Safety contact strips (n.c.) for direction “gate open”, or a resistor (8,2k
Ω
). The LED SLA
lights whenever the strips are activated. SLA causes STOP and reversal for a short way.
SEA
Limit switch „gate open“ (n.c.) . The LED SEA turns off when limit switch is pressed.
SEZ
Limit switch „gate closed“ (n.c.). The LED SEZ turns off when limit switch is pressed.
BS
STOP button (n.c.) or a jumper. The LED BS turns off when BS is pressed. BS stops gate
movement (electronic brake). The gate can only move again when BS is released and a new
signal is given.
BT
Push button for serial switching OPEN-STOP-CLOSE-STOP (n.o.). The LED BT lights when
BT or the corresponding remote button is pressed (see automatic closure, too).
