Important safety notes:
1. The automation system must be installed to good workmanship standards by qualified staff meeting the legal prerequisites and in
accordance with machinery directive 2006/42/EC and the EN13241-1, EN12453 and EN12445 standards.
2. Analyse the risks of the automation system and adopt any appropriate safety and warning measures.
3. Install controls, such as the key-operated selector switch, in such a way that the user is not in a hazard zone.
4. Affix the CE nameplate or label containing the hazard information and ID data of the automation.
5. Consign the instructions for use, safety information and EC declaration of conformity to the final user.
6. Ensure that the user has understood how to operate the automation correctly in automatic, manual and emergency modes.
7. After installation, try out the automation safety, signalling and release devices several times.
8. Inform the user in writing (for example, in the operating instructions):
a. of any residual risks for which no protection is provided, and foreseeable misuse.
b. That the power supply must be disconnected before the gate is released, when performing routine maintenance or during
cleaning of the automation area.
c. That the automation must be inspected frequently for visible damage, notifying the installer at once if any is found
d. That children must not be allowed to play in the immediate vicinity of the automation
e. That the radio remote controls and other control devices must be kept out of the reach of children.
9. A maintenance plan must be provided for the system (at least every 6 months) and the work done recorded in a log.
FIXING THE GEARMOTOR AND RACK
Decide the position of the motor, depending on whether the installation is right-hand (R) or left-hand (L).
Allow a minimum gap between the base of the motor and the end of the rack. In right-hand (R) installations, the motor must be
retracted by at least 20 mm to allow the magnetic limit switch to be fitted.
Before fixing the plate, make sure that:
- the surface is level and solid enough for effective mounting
- the passage for the electric wiring is on the correct side (fig.D)
- the base is perpendicular to the direction of travel (fig.D)
- the distance from the leaf allows the pinion to be correctly aligned with the rack (fig.D)
- the height allows the pinion and rack to mate correctly
- the gate can be released smoothly (fig.D)
- the 4 nuts provided have been fitted underneath the square holes.
For new installations where no solid base is available, a CPEVO foundation plate (optional) can be used, sunk into the concrete or
welded to existing structures (fig. E).
This replaces the plate supplied and must be positioned considering the factors already listed above.
Place the geared motor on the plate and fit the four screws (10, fig. A) in the slotted holes that allow horizontal adjustment if necessary
and if necessary use the 4 stud bolts (9, fig A) to correct the height and/or levelling of the motor.
For details on fixing the rack, follow the manufacturer's instructions. We generally recommend:
- the rack must have a M4 module and be specified to support the weight of the gate.
- the joints must not create jolts during gate travel.
- fix a piece of rack temporarily with clamps (fig. F) if it is difficult to achieve an even pitch at the joints.
- some models of rack can be installed with screws, using extra-long holes; in this case, it is useful to subdivide the margin of
adjustment by placing the screws in the middle of the slots.
Warning! We consider correct mating of the rack and pinion as fundamentally important.
They must be as centrally aligned as possible and above all there must always be a minimum clearance to prevent
abnormal loads on the pinion. Release the motor and ensure that the system runs evenly through the entire travel stroke.
If wear on the structure has created sagging which cannot be compensated for easily, the parts should be overhauled.
Once all adjustments and checks are complete, screw down the 4 screws (10, fig. A) and fit the covers (5).
Once installation has been completed, slacken the bleed screw indicated in figure A detail 15 (mod. EVO800, EVO1200 e
EVO1200R).
MAGNETIC LIMIT SWITCHES (fig. G)
These gearmotors come complete with two brackets with magnets (15 fig. A) and the relative sensor, fitted above the pinion (2 fig. A).
Warning! The two magnets are fitted on the bracket in a position that enables their recognition by the ECU. Dismantling and
swapping the position of either magnet may impair programming and/or operation.
Fit the fixing stud bolts and fit the two brackets temporarily to the opposite ends of the rack (fig. G).
Perform a series of checks with the motor released, moving the gate by hand.
- with the gate closed, the magnet must be facing the sensor
- open the gate and check the same situation with the opening magnet.
- the gap between the magnet and the sensor must not exceed 10mm (fig. H)
- the magnetic limit switch must not be tripped when the gate reaches the mechanical stop; this should occur at least 10 mm earlier.
Do not finally tighten the limit switch brackets; wait for the first operating tests. It may be necessary to correct the positions due to the
motor speed or gate inertia.
Warning! The use of magnetic or electric limit switches is not an alternative to the installation and maintenance of
mechanical limit stops for the gate. These devices must restrict the gate's maximum travel in all situations.
