2EN1. Warnings and general precautions1.1 - Safety warnings• WARNING! - Important safety instructions. The following in-structions are critical for personal safety. Incorrect installa-tion can result in serious injury.Read these instructions with care before starting; in case ofdoubt, contact King Gates Support Service.• WARNING! - Keep these instructions in a safe place to ena-ble future product maintenance and disposal operations.• WARNING! – According to current European legislation,the installation of an automatic door or gate must be in fullobservance of the standards envisaged by European Di-rective 2006/42/EC. (Machinery Directive) and in particularstandards EN 12445; EN 12453; EN 12635 and EN 13241-1,which enable declaration of presumed conformity of theautomation. Given the above, all product installation, con-nection, programming and maintenance work must be doneexclusively by a skilled and qualified technician, in obser-vance of local laws, standards, regulations and the instruc-tions in this manual.1.2 - Installation warnings• Before commencing the installation, check that this product is suit-able for controlling your gate (see Chapters 3 and 9). If it is not suit-able, DO NOT proceed with the installation.• All product installation and maintenance must be done with theautomated mechanism disconnected from the power mains.Before starting work, put a sign on the disconnection device thatsays “CAUTION! MAINTENANCE IN PROGRESS” to the discon-nection equipment.• Handle the product with care during installation, taking care toavoid crushing, denting or dropping it, or contact with liquids ofany kind. Keep the product away from sources of heat and nakedflames. Failure to observe the above can damage the product,and increase the risk of danger or malfunction. Should this occur,suspend installation work immediately and contact the King GatesSupport Service.• Do not modify any part of the product. Operations other than asspecified can only cause malfunctions. The manufacturer declinesall liability for damage caused by makeshift modifications to theproduct.• If the gate or door being automated has a pedestrian gate, then thesystem must include a control device that will inhibit the operationof the motor when the pedestrian gate is open.• Check that there are no points where people could becometrapped or crushed against fixed parts when the gate is fully open;if there are, provide protection for these parts.• The packing materials of the product must be disposed of in com-pliance with local regulations.1.3 - Warnings about use• This product is not intended to be used by persons (includingchildren) whose physical, sensory or mental capacities are redu-ced, or who lack the necessary experience or skill, unless suitableinstructions on how to use the product have been imparted by aperson responsible for their safety.• Do not allow children to play with the automation.• Do not allow children to play with fixed control devices. Keep remo-te control devices out of their reach as well.• When operating the gate, keep an eye on the automated mechani-sm and keep all bystanders at a safe distance until the movementhas been completed.• Do not operate the automation if anyone is working nearby (cle-aning, etc.); disconnect its power supply before permitting suchwork to be done.• Check the automation frequently for imbalance, wear and damage.Do not operate the system if it needs repair or adjustment; have itserviced exclusively by qualified and specialised technicians.2. Product descriptionThis product is intended to be used to automate swing gates. CAU-TION! – Any use other than the intended use, and any use inconditions other than those described in this manual, is im-proper and forbidden!The product is an electromechanical gearmotor, available in the ver-sions:LINEAR500230 / LINEAR50024 / LINEAR400230 / LINEAR40024.It is equipped with a 24V DC motor or 220V AC motor (depending onthe version) and a worm screw reduction unit.The gearmotor is powered off the external control unit to which it isconnected.In case of power outage, the gate can be operated manually by di-sengaging the gearmotor (par. 3.4).3. Installation3.1 - Pre-installation checksCaution! - The motor must be installed by qualified personnelin compliance with current legislation, standards and regula-tions, and the directions provided in this manual.Before proceeding with the installation:01. Check that the area to which the gearmotor is to be mounted islarge enough (fig. 2).02. Check the gate’s opening movement and the force exerted bythe motor: these depend on the position of the rear bracket. To setthe maximum opening position of the gate wing, refer to fig. 3.03. Establish the rough installation position for each component ofthe system and the most appropriate connection layout.Fig. 4 provides an example of an automation system using King Ga-tes components:a - Electromechanical gearmotorsb - Control unitc - Photocell paird - Mechanical limit switch pair (opening)e - Photocell pillarsf - Flasherg - Keyswitch/digital keypadh - Vertical electric lock
