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 ▲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.

Following are monitored devices acceptable for use with Universal Board:
IMPORTANT NOTICE FOR GATE OPERATORS
MANUFACTURED AFTER JANUARY 11, 2016:
All gate operators manufactured after January 11,2016 must have a monitored
input for EACH direction. In order to satisfy this requirement, all PowerMaster
gate operators with the universal board will have one monitored input for each
direction. The reverse (REV) terminal will function for the close direction, and
the open edge (OPN EDG) will function for the open direction. These terminals
will look for, or "monitor", the presence of a 10k in-line resistor. If either terminal
does not detect the presence of the monitored device the unit will function in
constant contact for this direction. Other terminals that will also monitor for
devices include Open Photo (OPN PHO) and Close Photo (CLO PHO) for each
respective direction.
Note: the first time a monitored device is added to the unit, the board must
"learn" what the monitored device is. To have the board learn the
monitored device, perform the following steps:
1. With the power off, hold both the open and close limits simultaneously.
2. Power up the unit and release your fingers from the limits. The unit has
now learned the monitored device.
EG: the operator detects there is a monitored device on the REV terminal,
but not the OPN EDG terminal. The operator will function in momentary
contact to close, and constant pressure to open.

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

INSTALLER SAFETY INSTRUCTIONS
BEFORE INSTALLATION
▲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.
▲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 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 disconnect mechanism 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.

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 how to operate the manual disconnect mechanism.
▲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.

▲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
▲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.
▲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

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.

▲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 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.

▲7. If your gate has open rollers, be sure roller guards have been
purchased and installed.
INCORRECT
CORRECT

▲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.
MANUAL DISCONNECT OPERATION
▲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.

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.
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.
