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 Photo-electric Sensors Instructional and Precautionary Signage
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.
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
1 Confirm gate operator model is specified by Installation and Maintenance Manual for
application type, gate size and frequency of use.
2 Confirm ALL appropriate safety features, such as gate edges, photo-electric sensors,
vertical posts and enclosed tracks, are specified.
3 Confirm the 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
procedures, such as manual disconnect mechanism procedure.
10 Confirm control design prohibits unauthorized use.

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 overtighten clutch or adjust force setting above minimum.
5 Install controls where user cannot touch gate while operating controls.
6 Install two or more warning signs on the gate to alert persons in the area of automatic
gate operation. Warning signs must be conspicuous.
7 Install operator inside fence line. DO NOT install operator on public side of fence line.
8 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 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 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.

Preparing the Installation
Pre-Installation Check List
!Check the gate. It must operate smoothly and freely. If necessary, lubricate the hinges, adjust
or repair the gate prior to operator installation. The gate must be level.
!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.
Wiring Specifications
Refer to Table 4 and Table 5 for wiring specifications.
A. The distances shown are measured in
feet from the operator to 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. These 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. All local codes must be strictly adhered
to. It is very important that operator is
properly grounded.
H. Do not run control wires in the same conduit
with power wires.
I. Do not run multi conductor or parallel
conductor cable for controls.
J. All power wiring should be dedicated and
protected.

NOTE: Calculated using NEC guidelines. Local codes and conditions must be reviewed for
suitability of wire installation. Master/Slave units must be installed on separate circuits.

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.
