IMPORTANT!
FORSLIDEGATEOPERATINGSYSTEMS
SAFETY IS EVERYONE’S BUSINESS
Automatic gate operators provide convenience and security to
users. However, because these machines can produce high
levels of force, it is important that all gate operator system
designers, installers, and end users be aware of the potential
hazards associated with improperly designed, installed, or
maintained systems. Keep in mind that the gate operator is a
component part of a total gate operating system.
The following information contains various safety precautions
and warnings for the system designer, installer and end user.
These instructions provide an overview of the importance of
safe design, installation, and use.
Warnings are identified with the ▲symbol. This symbol will
identify some of the conditions that can result in serious injury or
death. Take time to carefully read and follow these precautions
and other important information provided to help ensure safe
system design, installation and use.
▲WARNING:Gate operators are only one part of a
TOTAL GATE OPERATING SYSTEM. It is the
responsibility of purchaser, designer, and installer to ensure
that the total system is safe for its intended use. All
secondary entrapment safety devices must be
RECOGNIZED by U/L to ensure the safety of the complete
operating system.
▲WARNING:This operator is only intended for installation
on gates used for vehicular traffic. A separate pedestrian
access opening shall be provided which is designed to
promote pedestrian usage and shall be located such that
persons will not come in contact with the vehicular gate
during its entire path of travel.

SYSTEM DESIGNER SAFETY INSTRUCTIONS
▲1. Familiarize yourself with the precautions and
warnings for the installer. Users are relying on your
design to provide a safe installation.
▲2. The operator is supplied with a primary obstruction
sensing entrapment protection system. The
installation must also have a secondary entrapment
protection system installed, such as photoelectric
sensors or an electric edge system.
▲3. When designing a system that will be entered from a
highway or main thoroughfare be sure the system is
placed far enough away from the road to eliminate
traffic backup. Distance from the road, size of the
gate, usage levels, and gate cycle/speed must be
considered to eliminate potential traffic hazards.
▲4. The majority of injuries from slide gate operator
systems occur with Open Roller or Ornamental Grille
Type Gates. We strongly recommend the use of
roller guards. The illustrations and descriptive
captions found on the following pages provide
precautions to help eliminate injuries or fatalities.
Familiarize yourself with them when designing the
total system.
▲5. Design the gate system so a person cannot reach
over, under, around, or through the gate to operate
any controls. Never place controls on the gate
operator itself.

7
INSTALLER SAFETY INSTRUCTIONS
BEFORE INSTALLATION
▲1. Check to see that the operator is proper for this type,
size and class of gate and its frequency of use. If
you are not sure, consult factory.
▲2. Check to see that there are no structures adjacent to
the area, which may pose a risk of entrapment when
gate is opening or closing.
▲3. You must ensure that the gate has been properly
installed and works freely in both directions. Replace
8
or service any worn or damaged gate hardware prior
to installation. A freely moving gate will require less
force to operate and enhance the performance of
the operator as well as the safety devices used
within the system.
▲4. Install the gate operator on the inside of the property
and/or fence line. DO NOT install an operator on the
public side of the gate.
▲5. Severe injury or death can result from entrapment by
a gate. The operator is supplied with an obstruction
sensing primary entrapment protection system.
Additional safety equipment such as electric edges
or photocell sensors must be installed to provide the
required secondary entrapment protection system.
For assistance in selecting the correct type of safety
equipment, consult the factory.
▲6. Review the operation of the unit and become familiar
with the manual operation procedure and safety
features of the system.
▲7. You must install a pushbutton control or key switch
to allow for normal operation of the gate if the
automatic controls do not work. Locate the push
button or key switch and small warning placard
within sight of the gate in a secured area at least 10
feet or more from the gate and fence to keep users
away from the moving gate and fence.
▲8. Outdoor or easily accessed gate controls should be
of the security type to prohibit unauthorized use.

9
DURING INSTALLATION
▲1. Be aware of all moving parts and avoid close
proximity to any pinch points.
▲2. Disconnect power at the control panel before making
any electric service connections. Connection
location for controls and safety equipment can be
found on the wiring diagram, and in this manual.
▲3. Know the procedure for engaging and manually
operating the unit.
▲4. Adjust the open and close force adjustment on the
control board in each direction to the minimum force
required to operate the gate smoothly. DO NOT
increase the force adjustment setting to makeup
for rough spots in gate travel - FIX THE GATE
INSTEAD!
▲5. Locate the controls at least 10 feet from the moving
gate so that the user can observe the gate operation,
but is not able to come in contact with the gate while
operating the controls.
10
▲6. Attach large warning signs provided to each side
of gate in the most conspicuous place. Mount
control station and smaller warning placard
together within sight of the gate opening.
Moving Gate Can Cause
Serious Injury or Death.
KEEP CLEAR! Gate May Move
at Any Time. Children Should
Not Operate Gate. Operate
Gate Only When Area is in
Sight and Free of People
and Obstructions.
AFTER INSTALLATION
▲You are responsible for ensuring that the end
user understands the basic operations and
safety systems of the unit, INCLUDING THE
MANUAL OPERATION PROCEDURE.
▲Point out that the safety instructions in
brochure are the responsibility of the end user,
and then LEAVE THIS MANUAL WITH THE
END USER

11
END-USER SAFETY WARNINGS
The manufacturer of the gate operator does not know what
type of gate you have, or what type of automatic system is
installed on your gate. Be sure you’ve been fully instructed
on the sequence of operation for your specific gate
system(s). Keep the gate properly maintained and have a
qualified service person make repairs.
▲1. Be sure the following safety instructions are
distributed to all persons authorized to use your
gate.
▲2. KEEP GATEWAY CLEAR (Front and Back) AT
ALL TIMES. Your automatic gate is not for
pedestrian use. No one should ever cross the path of
the moving gate.
12
▲3. DO NOT allow children to play near your gate, or
to operate the gate.
▲4. DO NOT operate your gate system unless you can
see it when the gate moves.
▲5. Be sure a pushbutton or key switch has been
installed for manual electric operation in the event
your radio or card key does not work. Any
mounted control station should be located a
minimum of 10 feet from the gate so the gate
cannot be reached through or touched. Any
pushbutton located in a building should be
installed within sight of the gate.
▲6. DO NOT operate any controls without watching
the movement of the gate.

13
▲7. If your gate has open rollers, be sure roller guards
have been purchased and installed.
INCORRECT
CORRECT
14
▲8. Your gate system is required to have a primary
and a secondary entrapment safety system
installed and maintained.
▲9. If your gate closes automatically, loop detectors
should be installed to detect the presence of a
vehicle.
▲10 DO NOT increase force adjustment to compensate
for a damaged gate. The gate should always be
maintained to operate manually as easily as
possible to provide maximum protection.
▲11. Check all safety systems at least once per month
for the correct force, speed and sensitivity. Gate
must reverse when hitting a rigid object, or when a
non-contact sensor is activated. If these
functions are observed to operate improperly,
discontinue use and have it serviced
immediately!
▲12. You are responsible for ensuring that warning
signs are installed and maintained on both sides
of your gate.
▲13. To ensure safe operation of this equipment, you
must read this safety manual and keep it for
reference.

SAFETY WARNINGS FOR OPEN-ROLLER GATES
AND ORNAMENTAL GRILLE-TYPE GATES
▲WARNING: INJURIES ASSOCIATED WITH
AUTOMATIC GATES ARE MAINLY INCURRED
WITH OPEN-ROLLER GATES AND ORNAMENTAL
“GRILLE TYPE” GATES.
OPEN-ROLLER GATES
▲Injuries occur when people get their hands caught
between the top of the gate and the roller. This
potential pinch point should be guarded whenever an
automatic operator is installed. Roller Guards are
available from various fence suppliers for refitting of
these rollers.

17
ORNAMENTAL “GRILLE TYPE” GATES
▲Injuries occur when people put their arms through
openings in the grilles when the gate is operated. The
person cannot retract his/her arm and it gets caught
between the grille and the fence post or fence. The
potential hazard must be guarded. It can be simply
done by placing a screen mesh on the gate and fence
in the area of the gate. The screen must be a
minimum of 4 feet high from the bottom (unless the
gate and fence are shorter) with openings that a 2¼-
inch sphere cannot fit through. This will help to
prevent access through openings when the gate
travels.

This unit is supplied with a current sensing system, which
will stop the gate when it encounters an obstruction and then
backs the gate off approximately 2 inches. If the gate is
started again and a second encounter occurs before hitting a
limit switch, the gate will stop and sound a warning signal. A
constant pressure control will then be needed to start the
gate. This sensing system has sensitivity adjustments
located on the printed circuit board. The force required to
activate the system may be adjusted in both OPEN and
CLOSE directions separately. Start at minimum and
increase force setting until it is just over what is required to
move the gate smoothly without any nuisance tripping.
WARNING: NEVER INCREASE FORCE SETTING TO MAKE UP
FOR A GATE THAT IS NOT MAINTAINED PROPERLY. THIS
WILL DESENSITIZE THE OPERATION OF THE SAFETY
SYSTEM.

SECONDARY OBSTRUCTION SENSING DEVICES
Another sensing device (Either a contact or a non-contact
system) must be installed and connected to this unit to
increase protection against entrapment per U/L
requirements.
NOTE: All safety device contacts must be NORMALLY OPEN.
NOTE: 24 VAC power is available at terminals A & B for
devices that may require it (i.e., photo eyes, wireless edges,
etc).
CONTACT SENSOR INSTALLATION:
NOTE: Wireless sensors must be installed so there is no
signal interference.
NOTE: All hard wiring to safety edges must be installed so
there is no threat of mechanical damage to wiring between
components, when the gate is moving.
1. Install electric edge sensors in locations shown below.
NOTE: A separate pedestrian gate must be installed if there is
no other entry access but the vehicular gate.

NOTE: Leading edge is connected to terminal #13 and terminal
#14. Trailing edge, Post Mounted edge and Fence Mounted edge
are connected to terminal #12 and terminal #14.
3. After sensors are mounted and electrically connected,
turn on the power.
4. Test the close obstruction sensing system for proper
operation, by depressing the leading edge sensing
strip while the operator is running closed.
NOTE: The operator should stop and reverse a short
distance and then stop.
5. Run the operator to the close limit.
6. Test the open obstruction sensing system by
depressing one of the other three edge sensors while
the gate is opening.
NOTE: The operator should repeat the STOP AND REVERSE
procedure.
7. Run operator to the close limit and repeat step #6 for
the other two edges.

NON-CONTACT SENSOR INSTALLATION
1. Install photoelectric cell as close to inside of gate as
possible.
2. Photocells should be installed across the gate
opening and behind the gate (as shown below) at
least 10 inches above ground.
NOTE: A separate pedestrian gate must be
installed if there is no other entry access but the
vehicular gate.
