Product Description; Installation; Preliminary Checks; Typical System - Nice rondo Instructions Et Recommandations Pour L'installation

1) Product description

RONDO is a gearmotor for spring-balanced rolling gates. It is suitable
for the automation of rolling gates having a maximum height of 6m
and weighing up to 180kg. The gearmotor may be mounted on rolling
gates with a spring shaft diameter of 42mm, 48mm and 60mm.

2) Installation

2.1) Preliminary checks

Please keep in mind that automatic rolling gate systems may only be
installed by qualified personnel in compliance with the legislation in
force. Make sure that:
• The packing is undamaged and contains all the parts shown in
Fig. 1.
• The rolling gate opens and closes without presenting points of
greater friction.

3 release knob (only on versions with brake)

2.3) Mounting

1. Close the rolling gate all the way in order to make the spring
shaft accessible and drill an 11mm diameter horizontal hole
90mm from the middle of the spring shaft; Fig. 4
2. Remove the two half ring nuts after loosening the two M8
screws; Fig. 6
3. Remove the slide ring; Fig. 7
4. Slide out the plate in the direction indicated by the arrow; Fig. 8
5. Measure the diameter of the spring shaft. If the diameter of the lat-
ter is 60mm, proceed with the installation. If the shaft has a diam-
eter of 48mm or 42mm, install the adapters provided; Fig. 9
6. Reinstall the plate removed at point 5, paying attention to the
direction of assembly, and screw on the four screws provided;
Fig. 10
7. Mount the adapter ring removed at point 4 and grease its outer
surface slightly; Fig. 11
8. Insert and tighten the M10 screw; make sure you thread it
through the hole drilled in the spring shaft according to the
instructions under point 1; if necessary, use the adapter. Fig. 12
9. Tighten the two M10 screws so as to secure the gearmotor to
the spring shaft. Secure the two screws with lock nuts; Fig. 13
10. Drill a hole in the spring shaft for the power and release wire (only
on versions with brake); Fig. 14
11. Assemble the release knob, with all the adjusters tightened (A),
insert the wire and, holding it tight, secure it with the terminal (B).
(only on versions with brake); Fig. 15
12. Execute the release manoeuvre by turning the bottom knob
clockwise to loosen it. Check manually to make sure that the
gearmotor is released. If necessary, operate the adjusters to
eliminate any slack; Fig. 16
13. Slightly grease the teeth on the ring gears removed at point 3,
then assemble them, tightening the two M8 screws well; Fig. 17
14. Measure the diameter of the spring boxes. If their diameter is
200mm, proceed with the installation.

The spring boxes may have a diameter of 200mm / 220mm.
The two ring nuts are made of die-cast aluminium. The gearmotor is
equipped with a micrometric screw stop and mechanical position
memory.
• The rolling gate is well balanced, i.e., if it is stopped in any posi-
tion it must not display a tendency to start moving again.
• The rolling gate moves silently and smoothly.
• Refer to Fig. 2 to make sure that the mounting area is compati-
ble with the overall dimensions of the gearmotor.

15. Otherwise, if the diameter is 220mm, use the appropriate
adapter (B); Fig. 18
16. Remove the cover that protects the terminals. Loosen the cable
gland. Make the connections Fig. 19. Tighten the cable gland
screws. Close the cover that protects the terminals.
17. Using a screwdriver, remove the glass for the adjustment of the
limit switches; Fig. 20
18. Position the last segment of the rolling gate on the half ring nut
and drill an 11-mm diameter hole through it to match the hole in
the half ring nut;
19. Tightly fasten the rolling-shutter frame to the gearmotor using
screw and washer M10. Fig. 21
20. Release the gearmotor (only on versions with brake) and open
and close the rolling gate manually, making sure that it slides
smoothly. Lock the gearmotor again by tightening the release
knob; Fig. 22
21. DOWN LIMIT SWITCH ADJUSTMENT (closing)
Using the reverser switch, command the gearmotor to perform a
down manoeuvre until the limit switch is triggered. In the instal-
lation illustration, the closing manoeuvre limit switch is the one
shown in Fig. 23
22. ADJUSTING THE ASCENT LIMIT SWITCH (opening)
Pull the clip outwards while rotating the wheel indicated by the
arrow. Bear in mind the fact that approximately 1 cm of its trav-
el corresponds to 1 m of upward movement. Release the clip.
Power the gearmotor so it starts rising, and check that the
rolling-shutter stops in the position required. Fig. 24.
Continue to make adjustments until you reach the position
required;
23. Reinsert the limit switch glass, paying attention to the mounting
direction; Fig. 25
24. In case the installation is contrary to the one described, proceed
in the reverse order so that the second limit switch will regulate the
down movement, while the first one will regulate the up movement.
