INSTALLATION: ASSEMBLY AND CONNECTION OF COMPONENTS
––– STEP 5 –––
WARNINGS
• Incorrect installation may cause serious physical injury to those
working on or using the system.
• Before starting automation assembly, make the preliminary checks
as described in STEP 3.
5.1 - INSTALLING THE GEARMOTOR WU1SK
WU1SK is an electromechanical gearmotor comprising a helical gear
reducer and 24 V dc motor; it is fitted with a mechanical release with key,
which enables manual movement of the gate in the event of a power failure. The gearmotors can be anchored to the ground below the gate (if
there is a clearance of at least 90 mm), or installed underground with the
relative foundation plates.
The slotted arm and relative fixing plate enable connection of the gearmotor to the gate leaf.
WU1SK gearmotors are designed for two types of installation:
A) Underground installation
(see paragraph 5.1.1).
B) Surface-mounted (see paragraph 5.1.2)
If there are problems inserting the gearmotor under the leaf, we recommend removing the leaf to facilitate work.
5.1.1 - Underground gearmotor installation
01. Prepare the foundation pit, observing the specifications in paragraph
3.1 “Preliminary checks”, and in particular positions “A” and “B”
obtained from Table 1;
02. Lay the duct for routing the electric cable (fig. 7);
03. Separate the motor from the foundation plate;
04. Insert the four anchor bolts [B] in the foundation plate, securing the
above and below with two M8 nut types [A] and [C]; observe the
maximum height from the protruding side as shown in fig. 8;
05. Cast concrete into the pit;
06. Embed the plate in the concrete, taking care to level it.
07. When the concrete is sufficiently dry (after a few days), remove the 4
internal nuts which will no longer be used;
08. Fix bracket [D] onto the slotted arm, inserting bush [F] and spacer
[E] on screw [G]; then tighten the screw and bracket fully down as
shown in fig. 9;
09. Prepare the gearmotor inserting washer [L] in slotted arm [M], then
tighten fixing screws [I] fully down and close, inserting the cover [H]
(fig. 10);
10. Using a slotted screwdriver, remove the two release covers [N] (fig. 11);
11. Tilt the gearmotor, rest it on the plate and tighten the 4 self-locking
nuts [R] and washers [S]. Seal off the lock nuts, at the rear by
means of the nut caps [P] and at the front with the release covers
[Q] (fig. 12);
12. Insert the electric cable through the duct until it reaches the control
unit. If necessary, use a junction box for connection of the gearmotor
cable and cable to the control unit.
13. Refit the leaf if removed, and turn to the “gate closed” position.
14. Release the gearmotors by means of the relative release keys (see
paragraph “Releasing the gearmotor” on page 29) and turn the slotted arm until the fixing plate touches the leaf;
15. Position the fixing plate at the envisaged distance (position “C” of
Table 1 on page 3);
16. Provisionally secure the bracket to the leaf with a clamp; test a num-
ber of manoeuvres moving the gate by hand; check that the bracket
slides smoothly in the slot of the arm and that there is always a margin of at least 5 mm on the slot;
17. Fix the bracket permanently using screws suited to the leaf material;
18. Block the gearmotor again using the release keys (see paragraph
11.3 - User’s Guide) and close the release covers.
IMPORTANT!
- The following assembly phases show installation of a gearmotor
model WU1SK.
- To ensure correct system operation, mechanical stops must be
mounted on the floor or wall at the maximum leaf opening and closing
points. Note - These stops are not supplied in the pack and are not
part of the Mhouse product range.
5.1.2 - Surface-mounted gearmotor installation
01. Ensure that the fixing surface is perfectly smooth, level and sufficiently compact. WU1SK is not supplied with fixing devices, which must
be chosen also on the basis of the fixing surface material.
02. Select the fixing position, observing the specifications in paragraph
3.1 “Preliminary checks”, and in particular positions “A” and “B”
obtained from Table 1;
03. Lay the duct for routing the electric cable (fig. 14);
04. Separate the motor from the foundation plate;
05. Fix bracket [A] onto the slotted arm, inserting bush [C] and spacer
[B] on screw [D]; then tighten the screw and bracket fully down as
shown in fig. 15;
06. Prepare the gearmotor inserting washer [G] in slotted arm [H], then
tighten fixing screws [F] fully down and close, inserting the cover [E]
(fig. 16);
07. Using a slotted screwdriver, remove the two release covers [I] (fig. 17);
08. Trace the drilling points at the envisaged location using the founda-
tion plate as a reference and using a drill to make the holes.
09. Insert the gearmotor on the plate, positioning the entire assembly
over the holes, and secure permanently using screws suited to the
type of fixing material;
10. Seal off the fixing points at the rear with the nut caps [L] (if possible;
this depends on the type of fixture) and at the front with the release
covers [M] (fig. 18);
11. Insert the electric cable through the duct until it reaches the control
unit. If necessary, use a junction box for connection of the gearmotor
cable and cable to the control unit.
12. Refit the leaf if removed, and turn to the “gate closed” position.
13. Release the gearmotors by means of the relative release keys (see
paragraph “Releasing the gearmotor” on page 34) and turn the slotted arm until the fixing plate touches the leaf.
14. Position the fixing bracket at the envisaged distance (position “C” of
Table 1 on page 3);
15. Provisionally secure the bracket to the leaf with a clamp; test a number of manoeuvres moving the gate by hand; check that the bracket
slides smoothly in the slot of the arm and that there is always a margin of at least 5 mm on the slot;
16. Fix the bracket permanently using screws suited to the leaf material;
17. Block the gearmotor again using the release keys (see paragraph
11.3 - User’s Guide) and close the release covers.
Make electrical connections. Refer to figure 23 and step 6.
