CONTROL and CONNECTION ELEMENTS

Control elements
It is possible to control door OPENING and CLOSING with the
buttons integrated in the cover in automatic and/or deadman mode.
If set in automatic mode, the door can be stopped at any time with
the STOP button.
It is possible to connect other control elements, a triple button for
example, for control from outside.
A traction-activated switch, installed inside or outside, controls the
door in the OPEN-STOP-CLOSE function.
If the optional radio receiver is connected, it is always possible to
stop the door with the manual radio transmitter.
Connection of power supply cable (fig.1)
A 16A EEC plug is connected to terminals L1, L2, L3 and the PE
terminal.
The UST2 station can also be connected with the optional three-
phase main switch.
In this case the EEC plug is to be removed during assembly.

Three-phase gearmotor connection (fig. 2)
The three-phase gearmotor is to be connected to terminals U, V, W
and PE. If the gearmotor is equipped with a N neutral conductor, it is
to be connected to loose terminal N of the power supply cable, for
a brake activated by a 230 V rectifier for example.

Jumper
A jumper is fitted between terminals STOP (J8) and DW (J25) in
terminal block X5, and a jumper is inserted respectively on contacts
SH-AUF (J2) and (J13).
Direction of rotation control
Once the gearmotor is connected, it is necessary to check the
direction of rotation in deadman mode with the OPENING and
CLOSING buttons.
It is necessary to disconnect the EEC plug and reverse the U and
V connections (phase reversal) if the direction of rotation does not
correspond to the direction of the arrow on the pressed button.
Limit switch setting (fig.3)
The two OPENING and CLOSING limit switches are to be
connected like contacts with zero potential to the E-OPENING (J8)
and E-CLOSING (J9) terminals of terminal block X5 in the UST2
control unit. The circuit with the integrated safety limit switches is to
be connected to the STOP (J5) terminal of terminal block X5.
Disconnect the SH-OPENING (J2) jumper!
The procedure for setting the limit switches is shown below.

Connection of direct safety switches
The safety elements that directly intervene in the control process are
connected to terminal J6 of terminal block X5. The emergency stop
or safety line attachment, anti-entrapment safety device and safety
device for the wicket door are between them.
Connection of the transmitters of the OPEN, STOP,
CLOSE controls (fig.4)
For control from outside, it is possible to connect a triple button
to terminal block X3 of the UST2 control unit. In this case the two
OPEN and CLOSE buttons are to be made as closing contacts (NO).
The STOP button is connected to the safety circuit, so it is to be
connected as an opening contact (NC).
If a Stop button is connected to terminal block X3, remove the
jumper from terminal J10 and connect the STOP button (opening
contact)!
