IMPORTANT!
FOR SLIDE GATE OPERATING SYSTEMS
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 Ÿ 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.
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.
Ÿ WARNING:

SYSTEM DESIGNER SAFETY INSTRUCTIONS
Ÿ 1. Familiarize yourself with the precautions and warnings for the

installer. Users are relying on your design to provide a safe
installation.
Ÿ 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.
Ÿ 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.
Ÿ 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.
Ÿ 5. Design the gate system so a person cannot reach through the gate to

operate any controls. Never place controls on the gate operator
itself.

INSTALLER SAFETY INSTRUCTIONS
BEFORE INSTALLATION
Ÿ 1. Check to see that the operator is proper for this type and size of

gate and its frequency of use. If you are not sure, consult factory.
Ÿ 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.
Ÿ 3. You must ensure that the gate has been properly installed and

works freely in both directions. Replace 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.
Ÿ 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.
Ÿ 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.
Ÿ 6. Review the operation of the unit and become familiar with the

manual disconnect mechanism and safety features of the system.
Ÿ 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.
Ÿ 8. Outdoor or easily accessed gate controls should be of the security

type to prohibit unauthorized use.

DURING INSTALLATION
Ÿ 1. Be aware of all moving parts and avoid close proximity to any pinch

points.
Ÿ 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.
Ÿ 3. Know how to operate the manual disconnect mechanism.
Ÿ 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!
Ÿ 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.

Ÿ 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.

WARNING

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
Ÿ You are responsible for ensuring that the end user understands

the basic operations and safety systems of the unit, including
the location and operation of the manual disconnect.
Ÿ Point out that the safety instructions in brochure are the

responsibility of the end user, and then LEAVE A COPY OF
THIS BROCHURE WITH THE END USER
8

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.
Ÿ 1. Be sure the following safety instructions are distributed to all

persons authorized to use your gate.
Ÿ 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.

Ÿ 3. DO NOT allow children to play near your gate, or to operate the

gate.

Ÿ 4. DO NOT operate your gate system unless you can see it when the

gate moves.
Ÿ 5. Be sure a pushbutton or key switch has been installed for manual

electric operation in the event your radio or card 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.
Ÿ 6. DO NOT operate any controls without watching the movement

of the gate.

Ÿ 7. If your gate has open rollers, be sure roller guards have been

purchased and installed.
INCORRECT

CORRECT

Ÿ 8. Your gate system is required to have a primary and a secondary

entrapment safety system installed and maintained.
Ÿ 9. If your gate closes automatically, loop detectors should be installed

to detect the presence of a vehicle.
Ÿ 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.
Ÿ 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!
Ÿ 12.

You are responsible for ensuring that warning signs are installed
and maintained on both sides of your gate.

Ÿ 13.

To ensure safe operation of this equipment, you must read this
safety manual and keep it for reference.

MANUAL DISCONNECT OPERATION
Ÿ Your operator is equipped with a pad lockable emergency disconnect for

manual operation. Be sure you have a key and understand how to
operate this equipment. To disengage operator, move red disconnect
lever to the left and latch it in place.
Ÿ WARNING: NEVER OPERATE THE MANUAL RELEASE WHEN THE

GATE IS MOVING.

SAFETY WARNINGS FOR OPEN-ROLLER GATES
AND ORNAMENTAL GRILLE-TYPE GATES
Ÿ WARNING:

INJURIES ASSOCIATED WITH AUTOMATIC
GATES ARE MAINLY INCURRED WITH OPEN-ROLLER GATES
AND ORNAMENTAL “GRILLE TYPE” GATES.

OPEN-ROLLER GATES
Ÿ 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.

4'
MINIMUM

ORNAMENTAL “GRILLE TYPE” GATES
Ÿ 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.

EMERGENCY CONTROL STATION OPTION
Provision has been made to change the control station operational mode to
one that would only be activated when the entrapment sensing system is in
stop mode; with the warning horn activated. This would give a person
access to control the gate in an emergency situation, but it would be
inoperative under normal circumstances. To activate this option, move
dipswitch #1 to the “ON” position.
NOTE: When this emergency mode of operation is activated, the control
station functions as a constant pressure control.

TIMER TO CLOSE OPTION
The operator is equipped with a timer to close option for use with OPEN
ONLY control devices such as a radio control, or card key control. The
AUTO RECLOSE TIMER adjustment screw is located on the printed circuit
board. The operator is shipped from the factory with this timer preset to the
off position; fully counter clockwise. As the timer adjustment screw is
rotated clockwise, the closing of the gate can be delayed from 2 seconds to
60 seconds. The timer to close will be activated whenever the gate is
stopped, except in the closed position.

LOOP DETECTOR SYSTEMS AND INSTALLATION
The diagram below depicts the typical loop options for a Slide Gate
installation.
1. The Exit Loop provides a signal to open the gate when a vehicle

enters the loop zone.
2. The Reversing Loops protect a vehicle in the loop zone from

being contacted with the gate by overriding any close signal
while the gate is open, and by reversing the gate if closing.

chart below will give an approximate length of wire required for
various loop dimensions and number of turns required.
CAUTION: The Loop wires and Lead-in wires must be a continuous
piece of wire without splices. Only use wire intended for this type of
application. (Type XHHW insulation 16AWG)
NOTE: Buried steel from drains or other systems may affect functioning of
the loop system. Check with the factory for advice on any special
installations. (1-800-243-4476).

SAFETY DEVICE CONNECTIONS
INHERENT OBSTRUCTION SENSING DEVICE:
NOTE: The gate MUST move smoothly and easily in manual operation
before attempting this adjustment.
TURN OFF POWER TO OPERATOR WHEN MAKING
WARNING:
ANY ADJUSTMENTS.
This unit is supplied with a speed 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 marked terminals 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 “CLO EDG” and “COM” terminals.
Trailing edge, Post Mounted edge and Fence Mounted edge are connected to
“OPN EDG” and “COM” terminals.
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.
8. Run operator to the close limit and repeat step #6 for the other two
edges.
NOTE: If an edge is activated twice or a second edge is activated
before a limit is hit (full open or close) operator will stop and sound a
warning horn. To reactivate system turn operator power switch off
then on.

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.

manufacturer’s specifications.
3 . Test the CLOSE obstruction sensing system for proper operation,
by blocking the beam across the gate opening while the gate is
running closed.
NOTE: The gate should stop and reverse a short distance and then
stop.
4. Run operator to close limit.
5. Test the OPEN obstruction sensing system by blocking the beam
mounted at the back area of the gate while the gate is running
open.
NOTE: The operator should repeat the stop and reverse procedure.
