power cable into the cable gland Fig. 12.
3. For connections refer to Fig. 13.
For the installation of two units R180N
R280N on the same shaft refer to Fig.
24 for electrical connections.
Operators R180N / R280N can be controlled with 200
BT and 200 MPS devices.
The electric brake allows you to lock the roller shut-
ter in any position. By locking the motor shaft, the
electric brake prevents manual handling or loss of
position as a result of the compensating springs be-
ing imbalanced.
1. Assemble the electric brake (Fig. 19).
2. Couple the electric brake on the motor shaft
(Fig. 20 ref. ).
Avoid excessive curves of the sheath
that would prevent the cable from slid-
ing in its interior.
3. Remove the limit switch casing.
4. Connect the electric brake (Fig. 13).
5. Reposition the limit switch casing.
6. Run the electric brake cable into the hole previ-
ously drilled on the shaft (Fig. 21).
7. Assemble the release knob (Fig. 22). The
controller (Fig. 22 ref. ) must be fully screwed.
8. Pull the cable and firmly tighten the clamp (Fig.
22 ref. ).
6.1 RELEASE OPERATION
switch settings (par. 5.1).
4. After the adjustments fully lower the roller shut-
ter and secure the limit switch housing, paying
attention not to crush the cables.
5. Close the front casing (Fig. 18) only after the
limit switch adjustment in order to maintain the
positions acquired.
To change/fine-tune the opening
and closing positions set with the previously described
procedure:
1. Move the roller shutter to its fully closed position
in order to have full access to the limit switch unit.
2. Rotate the limit switch ring-nuts clockwise or
counterclockwise in order to delay or bring
forward the actuation of the opening or closing
microswitches (Fig. 17).
3. Make some assessment movements and if
necessary repeat the process until stopping in
the desired positions.
For roller shutters larger than 4.5 metres, it is recom-
mended to install two operators R180N or R280N.
Install the operators in the positions shown (Fig. 23)
following the instructions of Chap. 2.4 and Chap. 3.
In the event of a power failure, the electric brake must
be first unlocked to manually lift the roller shutter.
• For the unlocking mechanism to be actuated,
retain the upper part of the knob and rotate
clockwise the lower part.
• To relock the gear motor, retain the upper part
of the knob and rotate counterclockwise the
lower part.

7. INSTALLATION OF TWO R180N/R280N
The 200BT equipment (Fig. 14) allows you to control
the automation with 2 separate buttons.
The 200MPS equipment offers a wide range of
operation logics.
For further details, refer to the instructions for the
selected equipment.

Before operating the automation, it is
necessary to perform the procedure for
adjusting the roller shutter stop posi-
tions.
The automation enables the automatic positioning
of limit switches with a single operation (opening
and closing).
The limit switch unit comes with pre-
positioned limit switches.
Do not act in any way on the limit
switches before carrying out the ad-
justment operation.
Make sure the electric brake is released (Chap.
6.1) or not installed and proceed with the following
procedure:
1. Lift the roller shutter manually and open it com-
pletely (desired height).
If the roller shutter cannot be lifted
manually, disconnect the power and
move the opening microswitch connec-
tion (Fig. 15 ref. ) as shown in Fig.
16 ref. . Reconnect the power and
control the roller shutter electrically.
2. Fully lower the roller shutter.
In case of electrical command op-
eration, restore the connection of the
opening microswitch as shown in
Fig. 16 ref. after disconnecting the
power.
3. At the end of the procedure, perform some
movements to assess the opening and closing
stop positions. If necessary, change the limit
