CONTROL and CONNECTION ELEMENTS
Connection of the three-phase power supply cable
(fi g.1)
A 16A EEC plug is connected to terminals L1, L2, L3 and the PE
terminal.
The connection to the UST1K station can also be carried out with
the optional three-phase main switch.
In this case it is possible to remove the EEC plug during assembly.
Control elements
It is possible to control door OPENING and CLOSING with the
buttons built into 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 for control from the
outside, a triple button for example.
A switch with a cable coming down from the ceiling, 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.
Direction of rotation control
If the door is in the lower fi nal position, now it is necessary to open
it by about 50 cm with the handle to prevent the track ropes from
coming out of their housing (sectional doors) or excessive winding of
the rolling shutter in the case of rotation is reversed.
Check the direction of rotation in deadman mode with the UP and
DOWN 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 arrown on the
pressed button.
Now power up (connect the EEC plug).
Limit switch setting (fi g.3)
The two OPENING and CLOSING limit switches must be connected
like zero potential contacts to terminals J27 and J26 of the
terminal block X7 in the UST1 control unit. The safety circuit with
the integrated limit switches is to be connected to terminal J29 of
terminal block X7.
It is also possible to connect a second, additional limit switch for the
opening function (J33/X6) and then choose between two different
OPENING positions (summer-winter switching) with a position switch
installed on the housing cover (optional) of the UST1K station,.
The procedure for setting the limit switches is described
below.

A Schuko plug is connected to terminals L1 (phase) and L2 (N) and
to terminal PE in the 1.1 kW UST1K – station. The plug is connected
to L2 (phase), L3 (N) and PE on the versions with higher powers (2.2
kW and 5.5 kW).
Connection to the UST1K-1.1 kW station can also be made with an
optional single-phase main switch.
In this case it is possible to remove the Schuko plug during assembly.
