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

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

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

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

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

5 6 7 8

Doc 01-20220 Rev D

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.

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 over-tighten cutch or adjust force setting above minimum.

Install controls where user cannot touch gate while operating controls.

Install controls where user has full view of gate operation.

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 7

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

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

Safety Information

Safety Precautions for Open-Roller Gates and Ornamental “Grill Type” Gates

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 ore 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 01-20220 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 arms 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 screen mesh on the gate to prevent access through openings anywhere the gate may travel.

Preparing the Installation

Pre-installation Check List

! Check the gate. It MUST

operate smoothly and freely. If necessary, lubricate, adjust or repair the gate prior to operator installation. The gate MUST be level and plumb.

! Some gates may only be as

wide as the gate opening. They may require a backframe to be constructed to allow for chain attachments. See Figure 4.

! Double check the size and weight of the gate to make sure that this operator is

proper for this application.

! If wiring has already been installed, check to make sure it meets the following

specifications and requirements.

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 fro 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.

When wire larger than 12 gauge is used , a separate junction box will be required for operator power connections. Not supplied .

All local codes must be strictly adhered to.

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

Do not run or parallel conductor cable for controls.

Single Phase – 120 Vac. – 60 HZ.

BATTERY BACK-UP

Should there be a power failure, the model SL500-11 will automatically switch over

to battery back up to run the gate. If battery is fully charged, it should be able to

run a standard size gate many complete cycles, (cycle = one full open and one full

close). The number may vary depending on idle time and weather conditions.

Battery specifications – Type = Sealed lead acid. Amp hours = 6.5 Max. charging

volt. = 13.7 BATTERY PRECAUTIONS:

NEVER place battery near or in fire. NEVER short the terminals. NEVER disassemble the battery. If dilute sulfuric acid contacts skin or clothes, wash immediately with water

and contact a doctor.

Preparing the Installation

INTERNAL OBSTRUCTION SENSING

Built-in motor current monitor. Will automatically “Learn” the current that the motor is using to open and close the gate. During gate operation, should the current rise above the learned setting (because of gate obstruction), the model SL500-11 will react. See program settings for more details.

POWER DISCONNECT SWITCH/EMERGENCY STOP

This switch will turn power (120 vac.) off at the operator. Will also act as an emergency stop. When turned off, the operator will immediately stop if it was running.

SPRING APPLIED, ELECTRICALLY RELEASED BRAKE

The purpose of the brake is to minimize overtravel caused by gate coasting. An added feature of the brake is to assist in preventing backdriving of the gate. The brake is spring applied whenever the motor is not running. Anytime the motor is running, 12 v.d.c. is sent to the brake to electrically release it.

MOTOR (12 V.D.C. / 150 WATTS)

The motor used in the model SL500-11 is a PMDC (permanent magnet direct current) gearmotor. The nominal characteristics of the motor are – 1/8 horsepower, 19:1 gear ratio (with all steel gears), no lkoad r.p.m. = 111, full load r.p.m. = 75, no load amps = 2.2, full load amps = 12.4, full load torque = 75 lb. in., starting torque = 90 lb. in., and it is rated for intermediate duty.

CIRCUIT BREAKER

15 amp. circuit breaker, with manual reset. Protects the secondary circuit (d.c. side) of the operator.

NOTE:

unit is operating from the batter, and then turned back on, the unit will NOT work. It will only work when 120 volts are re-applied.

If the power disconnect/emergency stop switch is turned off while the

MAXIMUM RUN SHUT OFF CIRCUIT

This is a self learning circuit. It will take the average amount of time between the opening cycle and the closing cycle and add 5 seconds to it. If this time should be reached during operation, then this circuit will shut of the operator.

REVERSAL DELALY CIRCUIT

Will not allow the operator to instantly reverse the gate, there will be a 1-1/2 second delay prior to operator reversing direction.

AUDIBLE WARNING

Built in sounder will activate four seconds prior to and during gate movement. Sound level is adjustable.

DIGITAL MICROPROCESSOR CONTROL BOARD

This circuit board contains all the logic, inputs and outputs for the system. It contains all the L.E.D.’s the programming button and displays. All input and output
