6 Safety Information

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. Gate systems design and installation 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

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

STEP 1: BEFORE INSTALLATION

1 Confirm gate operator model is specified by Installation and Maintenance Manual for

application type, gate size and frequency or use.

2 Confirm ALL appropriate safety features, such as gate edges, photo-electric sensors,

vertical posts and enclosed tracks, are specified.

3 Confirm gate system design reduces pinch points and protects against entrapment. 4 Confirm gate system design has pedestrian access separate from vehicular entrance. 5 Confirm gate system design reduces traffic backup. 6 Confirm warning signage is included in design. 7 Confirm gate moves freely before installation of operator 8 Repair or service worn or damaged gate hardware before installation of operator. 9 To avoid installation hazards, review the gate system operation and installation

10 Confirm control design prohibits unauthorized use.

procedures, such as manual disconnect mechanism procedure.

Safety Information 7

STEP 2: DURING INSTALLATION

1 Disconnect power at service panel before making any electrical connection. 2 Avoid pinch points, be aware of all moving parts. 3 Adjust clutch or load sensing device to minimum force setting. 4 Do not over-tighten cutch or adjust force setting above minimum. 5 Install controls where user cannot touch gate while operating controls. 6 Install controls where user has full view of gate operation. 7 Install two or more warning signs on the gate to alert persons in the area of automatic gate

operation. Warning signs must be conspicuous.

8 Install operator inside fence line. DO NOT install operator on public side of fence line. 9 Secure gate operator cover.

STEP 3: AFTER INSTALLATION

1 Test all safety features. 2 Train end user about basic functions and safety features of gate system. 3 Leave Installation and Maintenance Manual and Safety Instructions with end user.

8 Safety Information

Safety Precautions for Open-Roller Gates and Ornamental “Grill

OPEN-ROLLER GATES

Injuries occur when people get their or feet caught between the top or bottom of the gate and the gate roller. This potential pinch-point should be guarded against at all times. Enclosed style gate tracks are available for refitting of these rollers from many fence suppliers. Also, roller guards are available for installing over the rollers.

One more contact sensors shall be located at the leading edge, trailing edge, and post-mounted both inside and outside of a vehicular horizontal slide gate.

Doc 01-G0685 Rev D

Figure 2

Safety Information 9

ORNAMENTAL “GRILL TYPE” GATES

Injuries occur when people put their hands and arms through openings in the grill and the gate is operated. They cannot retract their arm and it gets caught between the moving gate grill and the stationary fence post or fence. This potential hazard can be averted by placing a 4’ screen mesh on the gate to prevent access through openings anywhere the gate may travel. See Safety Brochure for details.

10 Pre-Installation Check-List

01-G0685F2

Pre-Installation Check-List

Φ Check the gate. It must operate smoothly and freely. If necessary, lubricate, adjust, or repair the

gate prior to operate installation. The gate must be level and plumb.

Φ Some gates may only be as wide as the gate opening. They may require a back frame to be

constructed to allow for chain attachments.

Φ Double check the size and weight of the gate to make sure that this operator is proper for this

application.

Φ If wiring has already been installed, check to make sure it meets the following specification and

requirements.

Wiring Specifications

Refer to Table 5.

A. The distances shown in Table 5 are measured in feet from the operator the power source. B. These calculations are based on the National Electrical Code and allows for a 5% voltage

drop.

C. Supply voltage must be within 10% of the operator’s rating under load conditions. D. There calculations are based on stranded copper wire. E. It is highly recommended that only 90% of the distances shown be used; this will allow for a

10% safety factor.

F. For dual units, the distance shown should be cut in half. G. Permanent wiring is to be employed as required by local codes. H. All local codes must be strictly adhered to. It is very important that operator is properly

grounded.

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

Doc 01-G0685 Rev D

J. Do not run multi conductor or parallel conductor cable for controls. K. All power wiring should be dedicated and protected.
