Safety Information

Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application.

Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. The design and installation of gate systems must reduce public exposure to potential hazards.

A gate operator can create high levels of force, in its function as a component part of a gate system. Therefore, safety features must be incorporated into every design. Specific safety features include:

Gate Edges Enclosed Track Vertical Posts Guards for exposed

rollers Screen Mesh

Important instructions follow. These instructions are intended to highlight certain safety related issues. These instructions are not intended to be comprehensive. Because each application is unique, it is the responsibility of the purchaser, designer, installer and end user to ensure that the total gate system is safe for its intended use.

Photo-electric Sensors Instructional and

Precautionary Signage

Safety Instructions

Selected Instructions are highlighted with a precautionary symbol (see left margin). Failure to follow these selected instructions can result in serious injury or death.

STEP 1: BEFORE INSTALLATION

Confirm gate operator model is specified by Installation and Maintenance Manual for application type, gate size and frequency of use.

Confirm ALL appropriate safety features, such as gate edges, photo-electric sensors, vertical posts and enclosed tracks, are specified.

Confirm the gate system design reduces pinch points and protects against entrapment.

Confirm gate system design has pedestrian access separate from vehicular entrance.

Confirm gate system design reduces traffic backup.

Confirm warning signage is included in design.

Confirm gate moves freely before installation of operator.

Repair or service worn or damaged gate hardware before installation of operator.

To avoid installation hazards, review the gate system operation and installation procedures, such as manual disconnect mechanism procedure.

Confirm control design prohibits unauthorized use.

Doc 01-G0665 Rev C

STEP 2: DURING INSTALLATION

Disconnect power at service panel before making any electrical connection.

Avoid pinch points; be aware of all moving parts.

Adjust clutch or load sensing device to minimum force setting.

Do not overtighten clutch or adjust force setting above minimum.

Install controls where user cannot touch gate while operating controls.

Install two or more warning signs on the gate to alert persons in the area of automatic gate operation. Warning signs must be conspicuous.

Install operator inside fence line. DO NOT install operator on public side of fence line.

Secure gate operator cover.

STEP 3: AFTER INSTALLATION

Test all safety features.

Safety Information

Train end user about basic functions and safety features of gate system.

Leave Installation and Maintenance Manual and Safety Information with end user.

FOR GATE OPERATORS USING NON-CONTACT SENSOR(S)

See instruction supplied with sensor for proper placement. Precautions must be taken to reduce the risk of nuisance tripping of the sensor. If there are multiple areas of risk of entrapment or obstruction, then more than one sensor

should be incorporated into the system.

FOR GATE OPERATORS USING CONTACT SENSOR(S)

One or more sensors shall be located as shown on page 8. Care must be taken during the wiring of the sensor(s) to the operator. Make sure that the

wiring cannot be damaged or interrupted. When using a sensor with a gate edge transmitter, care must be taken to insure that the

RF signal is not interfered with or obstructed.

SECONDARY ENTRAPMENT PROTECTION

It is recommended that secondary safeties always be used for both the open and close directions. Use photo eyes, safety edges or both. In any case, the device must sense people. Loops cannot be used.

Safety Information

Safety Precautions for Swing Gates and Ornamental “Grill Type” Gates

ENTRAPMENT ZONES

Pedestrians must stay clear of the gate path, particularly the area where the gate can trap them, as shown in Figure 1.

01-G0665F18

Figure 1

Gate edges and/or photo-electric beams must be incorporated into the swing gate system to assist in the protection of people who may come near the gate operating system.

Also, injuries can occur when people put their hands and arms through openings in a grill type gate and it is operated. This potential hazard can be averted by placing a screen mesh on the gate to prevent access through the openings. See Figure 2.

Photo-Electric Beam

Always test Gate Edges an d

Photo Beams anytime they are

adjusted or serviced.

Preparing the Installation

Pre-Installation Check List

! Check the gate. It

or repair the gate prior to operator installation. The gate

! Double check the size and weight of the gate to make sure that it is proper for this application. ! If wiring has already been installed, check to make sure it meets the following specifications.

must

operate smoothly and freely. If necessary, lubricate the hinges, adjust

must

be level.

Wiring Specifications

Refer to Table 4 and Table 5 for wiring specifications.

The distances shown are measured in feet from the operator to the power source.

These calculations are based on the National Electrical Code and allows for a 5% voltage drop.

Supply voltage must be within 10% of the operator’s rating under load conditions.

These calculations are based on stranded copper wire.

It is highly recommended that only 90% of the distances shown be used; this will allow for a 10% safety factor.

For dual units, the distance shown should be cut in half.

G. All local codes must be strictly adhered

to.

It is very important that operator is

properly grounded.

Do not run control wires in the same conduit with power wires.

Do not run multi conductor or parallel conductor cable for controls.

All power wiring should be dedicated and protected.

ACTIVITY LED

Steady indication when gate is at either open or close limit.

1 second flash when gate is off a limit in normal operation.

2 second flash when an entrapment has occurred.

AUDIBLE WARNING DEVICE

If the operator should have a second inherent obstruction in sequence with the first; (i.e. back to back), the sounder will activate. Also, the sounder can be programmed to come on 3 seconds prior to gate movement, and remain on during gate movement.

THREE BUTTON CONTROL (SEQUENCE OF OPERATION)

Open, stop, close. Stop will override all other functions. If closing, Open will cause the operator to stop and reverse to full open. If gate is at its fully opened position, the Close function will cause the gate to close.
