Automatic closing
Function available with the K2 optional module only
The automatic closing function is to be set on the rotary position switch. If the
automatic closing function is enabled, the door closes from the final
position after the time set on the rotary switch has elapsed. Automatic
closing is interrupted when the Stop button or a safety device is
enabled.
Connection of the transmitters of the OPEN, STOP,
CLOSE controls (fig.4)
Function available with the K2 optional module only
For control from outside, it is possible to connect a triple button to
terminal block X3 of the UST1 control unit. In this case the two OPEN
and CLOSE buttons are made as closing contacts (NO).
The STOP button is connected to the safety circuit, so it is executed
as an opening contact (NC).
If a Stop button is connected to terminal block X3, remove the jumper
from terminal J9 and connect the STOP button (opening contact)!
It is possible to connect different closing contact control devices with
zero potential to the J11 terminal of the X3 terminal block, for example
a switch with cable coming down from the ceiling. The function of this
input corresponds to the CLOSE-STOP-OPEN-STOP sequential step
by step control.

Connection of an optical sensitive edge (fig.5)
Function available with the K2 optional module only
The safety optical sensitive edge is structured so that a beam of light
is interrupted along its entire length when it is activated. A receiver is
connected to the end of the contact bar so that its entire length can
be controlled.
If the contact bar has to be pressed to the ground, the reverse function
is neutralised by connecting a preliminary limit switch (additional pre-
limit switch) to terminal J21 of terminal block X5. In this case the
preliminary limit switch is to be adjusted about 5 cm above the ground.

Safety barrier
Photoelectric barrier connection (fig.6 a+b)
Function available with the K2 optional module only
It is possible to directly connect a photoelectric barrier to the UST1
device (to terminal block X5) to make the passage safe. If the infrared
beam of the photoelectric barrier is interrupted during the CLOSING
movement of the door, it blocks and reverses the direction toward the
upper final position.

ATTENTION:
The switching contact and the positive pole of the electronic
barrier system are connected to terminal J30/1 with positive
potential in a one-way photoelectric barrier with only three
connection points.
Remove the jumper from terminal J31 of terminal block X5 if
the photoelectric barrier is connected.
Connection of direct safety switches
The safety elements that directly intervene in the control process are
connected to terminal J6 of terminal block X2. The emergency stop or
safety line attachment, anti-entrapment safety device and safety device
for the wicket door are between them.
Connecting the control traction-activated switch
transmitter (fig.7)
It is possible to connect a switch with cable coming down from the
ceiling to terminal J11 of terminal block X3 in the UST1 control unit. The
function of this input corresponds to the CLOSE-STOP-OPEN-STOP
sequential step by step control.
