MECHANICAL LIMIT SWITCH SETTING
Mechanical limit switch setting
Attention! The procedure for setting the limit switches is explained on
the 5­6 pages that follow.
The stop positions with door in the up/down position are defined
with setting the limit switches.
The motor must be electrically connected for making this setting.
The limit switch board (fig.11 ­ limit switch board with 8 cams) 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 using the integrated OPEN,
CLOSE and STOP buttons in deadman mode.
If the OPEN button is pressed, the door should open; otherwise the
L1 and L2 phases on the control unit must be reversed after having
made sure the voltage has been cut off.
If the gearmotor was installed turned 180° (upside­down 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 correct the two emergency stop limit switches
so they trip after the limit switch.
Determining the lower position of the door
To set the limit switches for the lower position of the door, perform
the following operations (fig. 11):
Move the door to the desired CLOSE position.
Set the contact cam 3 Ei (white) so the limit switch is enabled.

Tighten the fixing screw A.
To get accurate adjustment, use the screw B.
Move the door into the desired OPENING position.
Set the contact cam 1 Eh (green) so the limit switch is enabled.
Tighten the fixing screw A.
To get accurate adjustment, use the screw B .
The safety limit switches 2 SEi and 4 SEh (red) must be set so they
intervene right after the control limit switch is passed.
The safety limit switches 2 SEi and 4 SEh (red) are factory­set so
they follow the limit switch at a short distance.
Check the correct position of the fixing screws 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 and 5
P1h are switching contacts with zero potential.
In automatic mode the 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.
In deadman mode it is not necessary to set it and it is used as a
contact with zero potential!
