There is a slot (X9) for a 1-channel radio receiver on the UST1 control
unit. For more details, see the instructions for using the receiver and
manual transmitter.
MECHANICAL LIMIT SWITCH SETTING
Mechanical limit switch setting (fig. 8-9)
Attention! The limit switches must be set in deadman mode!
The switching off positions with door in the up/down position are
defined by setting the limit switches.
The gearmotor must be electrically connected for making this setting.
The limit switch board (models with 8 limit switches) is accessible once
the limit switch guard is unscrewed.
If external control devices are not yet connected, it is possible to
control the door with the control unit supplied using the integrated
OPEN, CLOSE and STOP buttons in deadman mode.
If the OPEN button is enabled, the door must open; otherwise the L1
and L2 phases on the control unit must be reversed in zero voltage
conditions.
If the gearmotor was installed turned 180° (upside-down assembly),
the door must also open with the integrated OPEN button; otherwise
the L1 and L2 phases must be reversed in zero voltage conditions.
It is also necessary to adjust the two emergency stop limit switches so
they trip after the limit switch.

Switching off with door in low position
To set switching off with the door in the low position, the following op-
erations must be performed (fig. 9):
Move the door to the desired CLOSE position.
Set the contact cam 3 Ei (white) so the limit switch is enabled.
Tighten fixing screw A .
To get accurate adjustment, use screw B .
Move the door into the desired OPENING position.
Set the contact cam 1 Eh (green) so the limit switch is enabled.
Tighten fixing screw A .
To get accurate adjustment, use screw B .
The safety limit switches 2 SEi and 4 SEh red) must be set so they
trip right after the control limit switch is passed.
The safety limit switches 2 SEi and 4 SEh (red) are factory-set so they
follow the limit switch at a short distance.
Check that the fixing screws are in the correct position after the
operation test.
The additional limit switches 8 P2i and 7 P2h are closing contacts
with zero potential, and the additional limit switches 6 P1i (preliminary
limit switches) and 5 P1h (door half height) are switching contacts with
zero potential.
In automatic mode limit switch 6 is used as a preliminary limit switch.
Therefore, it is to be set so that it trips when the door reaches a
distance of 5 cm from the ground.
