1) GENERAL INFORMATION

Automatic system with 115 or 230V AC, single-phase power supply for industrial use, sliding gates. It is available in two versions:

YAK 20 OM 230VAC, for gates with 2000 kg max weight

YAK 20 OM 115 VAC for gates with 2000 kg max weight.

Both motors are equipped with anti-crash electronic device (encoder) and electronic braking.

3) PRELIMINARY CHECKS

For a good operation of the automatic system for sliding gates, the gate/door to be automated shall feature the following characteristics:

- the guide track and related carriers should be adequately sized and subject to maintenance (in order to avert excessive friction during the gate sliding).

- during operation, no excessive oscillations should be reported to the gate/door.

- the opening and closing stroke should be limited to a mechanical stop (according to the current safety regulation).

These preliminary checks are MANDATORY. It is expressly FORBIDDEN to use the YAK automatic system on doors and gates not in good conditions

or that have not undergone a correct maintenance.

4) INSTALLATION

4.1) OVERALL DIMENSIONS

Figure 1 shows the overall dimensions of the gear motor, expressed in mm.

Given the remarkable weight of the actuator, the device should be handled by at least 2 persons.

If only the control unit is to be reached, it is sufficient to remove the 4 "A" screws by lifting the upper cover.

Loosen the 4 "B" screws (Fig. 1) and entirely remove the front side of the system. Now all elements of the systems can be accessed.

4.2) FOUNDATION PLATE - DIMENSIONS

Fig.2 shows the installation dimensions of the foundation plate, expressed in millimetres. Two holes have been drilled on the plate for the passage of

cable. When the corrugated pipe is introduced, keep in mind that the hole to be used is the one shown in Figure 2 (ref. C).

If the rack is already installed, a fitting base, raised with respect to the floor, should be required. However, it is not advisable to lower the fitting surface.

If the rack used is the model RI.M4Z, the edge of the plate should lie perfectly parallel with respect to the door leaf and should be positioned at 33 mm.

If a different rack is used, find the correct distance by temporarily fitting it to the door/gate leaf, then place the gear motor and check that the pinion and

the rack are geared together.

4.3) INSTALLATION OF THE FOUNDATION PLATE (FIG. 3)

Through 4 "T" screw anchors in steel (not supplied), firmly anchor the foundation plate to ground by means of 4 bolts "B" (not supplied). Use the foundation

plate as drilling template.

To facilitate the fitting of bolts, 4 holes are provided on the plate (ref. F).

4.4) MOTOREDUCER FIXING

Fix the geared motor to the plate by means of the 4 screws V (M10x70), with the relevant plain washers R and grover washers Z, as indicated in the figure 4.

The threaded holes allow for the horizontal movement of the gear motor, which is required to gear/ungear the pinion to the rack.

4.5) HOW TO FIT THE RACK

Temporarily fit the rack by using clamps, for example. Check that the system is perfectly flat, then fit the rack to the gate with various welding points of

by using adequate screws.

Keep to the tooth pitch P, even from the rack spaces. To this purpose, it might be useful to match another piece of rack (Fig. 5 - Detail C).

Lastly fix the rack with screws V, making sure that, once the actuator is installed, around 2 mm backlash is left between the rack and the drive wheel

(see Fig. 6).

5) MANUAL OPERATION (FIG. 8-9-10)

In the event of power failure or malfunction, to manually operate the gate proceed as follows:

- After inserting the customized key C, turn it anti-clockwise and pull the lever L.

- The geared motor is unlocked and the gate can be moved by hand.

- To return to the normal operating mode, close the lever L again and manually activate the gate until it is geared.

6) HOW TO POSITION THE LIMIT SWITCH BRACKETS

Manually open the gate, leaving 1 – 3 cm space, according to the weight of the gate, between the gate/door and the mechanical stopper A (Fig. 12).

Then fix the bracket of the limit switch S in order that the micro-switch F of the limit switch is kept pressed.

Repeat this operation with closed gate/door.

NOTE: The limit switch bracket should be positioned in order to allow that the gate/door stops its movement without hitting the mechanical stopper.
