PRELIMINARY CHECKS AND IMPORTANT SAFETY NOTES FOR INSTALLATION
Before proceeding with installation, checks should be made on:
1. the solidity of the existing structure (posts, hinges and leafs) in relation to the force generated by the motor.
2. the provision of mechanical stops of suitable strength at the ends of the gate opening and closing strokes.
3. the bottom wheel/rail system and upper roller/guide system to ensure there is no rubbing or excessive
clearance.
4. the disabling of any manual locks.
5. the condition of any wiring already installed in the system.
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.
BRACKETS FIXING
Before reading the installation instructions, take note of the following basic concepts:
- the joint brackets (front and rear) must be mounted correctly at two different heights.
- the brackets supplied can be welded directly to the structure or secured with screws and screw anchors, provided
the system is able to withstand the forces imparted: by the actuator, by manual movement of the gate and (in certain
conditions) by the wind.
- the position of the brackets establishes the maximum opening angle and the length of the actuator's linear stroke;
consider that the longer the stroke of the lead screw, the greater the torque and the smoother the movements of the
gate leaf; on the contrary, with a short stroke, movements may be more abrupt and there will be less torque available.
Table TAB1 shows several examples of bracket positions; the measurements are guideline and should be used solely to
prepare for installation. Check which of the possible solutions is applicable to your automation project and perform a few
manual trials before fixing the brackets.
Assess these tolerances because the more dimensions "A" and "B" are similar, the smoother the movements of the gate
leaves.
The rear brackets are supplied in two parts (with non-welded plate) offering the freedom to: shorten or tilt the bracket or fix the
drilled bracket directly to the gate post (figs. E1, E2). For fixing with screw anchors and/or screws the bracket must be welded
to the plate as shown in fig. E (standard installation).
Even if the structure of ASY is designed to adapt to imperfections or structural deterioration of the fixing, the importance of
using maximum precision when levelling the brackets (fig. E3) cannot be underestimated.
The height of the brackets is established easily using a spirit level; the front bracket must be 55 mm lower (fig. F); in addition,
calculate the final height of the actuator such as to allow correct outlet of the electrical cables or choose a higher position to
reduce the accumulation of dirt, grit and moisture (fig. G).
After having secured the rear bracket and marked the height of the front bracket, you can calculate distance "E" with the aid of
the table (TAB1) or proceed as follows:
- secure the actuator as shown in fig. H
- fix the front bracket to the actuator
- bring the gate leaf to its fully closed position
- bring the actuator to its closed position (a few millimetres before the maximum extension)
- place the front bracket on the gate leaf and mark the holes
Before final fixing (screws or welding) perform a manual opening and closing movement and check the actuator is level (fig.
G).
