Connecting a sensitive edge with 8.2 kOhm
(Optional, only with additional dedicated controller)
It is possible to connect an electrical and/or pneumatic safety bar to
the UST2 device using an additional control unit.
It is to be connected to a resistance (8.2 kOhm) in order to be able
to monitor the entire electrical circuit of the safety bar.
The additional preliminary limit switch is to be set so that the door,
when closing, activates the limit switch 55 cm above the ground.
Connecting the functional photoelectric barrier (fig. 5)
It is possible to directly connect a photoelectric barrier to the UST2
device (to terminal blocks X3 and 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.

Connecting the safety switch for wicket door (fig.6)
The safety switch is to be connected to terminal J8 of terminal block
X5 in the doors with built-in service wicket door.
Attention! Remove the jumper (J8)!

Connecting the control switch transmitter with cable
coming down from the ceiling (fig.7)
It is possible connect a ceiling traction-activated switch (closing

contact) to terminal J11 of terminal block X3 in the UST2 control
unit. The function of this input corresponds to the CLOSE-STOP-
OPEN-STOP step by step control.
