c. Unscrew the four screws securing the roller support located on the opposite
side of the motor.
d. Pull out the shaft end with a plug (opposite the motor).
e. Remove the roller from the casing.
3. Make mounting holes in the casing.
4. Mount the curtain housing using steel fasteners adequate for the substrate material
and for the position of the mounting surface (ceiling/wall): fasteners with a joining
element of at least Ø10 in diameter are recommended, e.g. M10 (such as HK8 HILTI
anchors). Note the length of the fastener inside the casing as it cannot damage the
fabric.
5. When the casing has been installed, put the roller with fabric inside. Follow the above
steps in reverse order. Make sure that the position of the roller is the same as before
removing it.
6. Secure the roller by locking pins at both ends.
7. Install the side guides, if ordered, using steel fasteners.
Connect the free terminals of MECU XL
(fig. 12)
to the control device, i.e. the mcr
9705 or mcr 0204 control unit, and to the 230 V power supply. Observe polarity (+ to
+, - to -). The mcr 9507 control unit should be set to the door control mode (see the
OMM of the smoke vent control unit) or the mcr 0204 control unit should be set to the
curtain control mode.
8. Make sure that there are no obstacles under the curtain and check if the curtain rolls
out to the desired height and rolls up properly. Adjust the length of the fabric feed, if
required (see: Limit switch adjustment
– page 9).
9. Having checked and adjusted it, close the access cover.
10. Check the system operation by triggering the alarm from all available sources.
Curtains with a bottom bar masking element:
Masking elements are supplied separately. They are suitable for installation at the
already mounted and adjusted curtains.
1. Before installing the masking element, attach the bracket to a spring which is
attached to the masking element by default. The installation takes place on site by
putting the spring in the prepared slot in the bracket.
2. The masking element with the bottom bar bracket is to be attached using 4.8 x13
buttonhead self-drilling screws.
3. Restrictions on the use of the masking element with holders
(fig. 4, 5).
Multi-modular curtains should be installed following the order of modules (first the
edge module, then the central one and then the edge one again) and design sizes of material
overlaps in the individual modules.
For a group of curtains with a common bottom bar, all curtain modules should be
powered by the same source, i.e. by a single mcr 9705 or mcr 0204 control unit. Electrical
connections should be as specified in the OMM of the control units.
The installation of a single bottom bar for a group of curtains and/or the masking
element should be as specified in a separate manual.
NOTE:
In the case of curtains longer than 4 m, there is foam padding inside the casing. Make
sure to remove it before powering the curtains.
Failure to remove the foam padding
may result in damage to the drive or fabric.
