IMPORTANT SAFETY INFORMATION
IMPORTANT SAFETY INSTRUCTIONS
!WARNING! To reduce the risk of severe injury or death.
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Never let children operate or play with gate controls. Keep the remote away
from children.
3. Always keep people and objects away from the gate. NO ONE SHOULD
CROSS THE PATH OF THE MOVING GATE.
4. Test the gate operator monthly. The gate MUST reverse on contact with
a rigid object or when an object activates the non-contact sensors. After
adjusting the force or the limit travel, retest the gate operator. Failure to
adjust and retest the gate operator properly can increase the risk of injury or
death.
5. Use the manual release only when the gate is not moving.
6. KEEP GATES PROPERLY MAINTAINED. Read the owners manual. Have a
qualified service person make repairs to gate hardware.
7. The entrance is for vehicles only. Pedestrians must use a separate entrance.
8. Every gate operator installation MUST have secondary protection devices
against entrapment, such as edge sensors and photo beams more in
particularly in places where the risk of entrapment is more likely to occur.
9. SAVE THESE INSTRUCTIONS.
IMPORTANT INSTALLATION INSTRUCTIONS
1. Install the gate operator only when:
a. The operator is appropriate for the construction of the gate and usage
Class of the gate (refer to page 5),
b. All openings of a horizontal slide gate are guarded or screened from the
bottom of the gate to a minimum of 4 feet (1.22 m) above the ground to
prevent a 2-1/4 inch (57.2 mm) diameter sphere from passing through the
openings anywhere in the gate, and in that portion of the adjacent fence
that the gate covers in the open position,
c. ALL EXPOSED PINCH POINTS ARE ELIMINATED OR GUARDED, AND
d. GUARDING IS SUPPLIED FOR EXPOSED ROLLERS.
2. The Operator is intended for installation only on gates used for vehicles.
Pedestrians must be supplied with a separate access opening. The pedestrian
access opening shall be designed to promote pedestrian usage. Locate the
gate such that persons will not come into contact with the vehicular gate
during the entire path of travel of the vehicular gate.
3. The gate must be installed in a location so that enough clearance is supplied
between the gate and adjacent structures when opening and closing to
reduce the risk of entrapment. Swinging gates shall not open in to the public
access areas.
4. The gate must be properly installed and work freely in both directions prior to
the installation of the gate operator. Do not over-tighten the operator clutch
or pressure relief valve to compensate for a damaged gate.
5. The gate operator controls must be placed so that the user has full view of
the gate area when the gate is moving AND AWAY FROM THE GATE PATH
PERIMETER.
!WARNING! Not Following these instructions may cause severe injury or death.

VIKING TECHNICAL SUPPORT 1.800.908.0884 7
IMPORTANT SAFETY INFORMATION
IMPORTANT INSTALLATION INSTRUCTIONS (Continued)
6. Controls intended for user activation must be located at least six feet (6’)
away from any moving part of the gate and where the user is prevented from
reaching over, under, around or through the gate to operate the controls.
Outdoor or easily accessible controls shall have a security feature to prevent
unauthorized use.
7. The Stop and/or Reset button must be located in the line-of-sight of the gate.
Activation of the reset control shall not cause the operator to start.
8. All warning signs and placards must be installed where visible in the area of the
gate. A minimum of two placards shall be installed. A placard is to be installed
in the area of each side of the gate and the gate be visible to persons located
on the side of the gate on which the placard is installed.
9. For gate operators using non-contact sensors (Photo Beams or like) in
accordance with section 31.1.1 of the UL standard:
a. The operator is appropriate for the construction of the gate and usage
Class of the gate (refer to page 5),
b. Care shall be exercised to reduce the risk of nuisance tripping, such as
when a vehicle, trips the sensor while the gate is still moving, and
c. One or more non-contact sensors shall be located where the risk of
entrapment or obstruction exists, such as the perimeter reachable by a
moving gate or barrier (refer to page 6).
d. Use only Omron E3K-R10K4 photoelectric eye to comply with UL 325
10. For a gate operator utilizing a contact sensor (Edge sensor or like) in
accordance with section 31.1.1 of the UL 325 standard:
a. One or more contact sensors shall be located where the risk of entrapment
or obstruction exists, such as a the leading edge, trailing edge, and post
mounted both inside and outside os a vehicular horizontal slide gate (refer
to page 7).
b. One or more contact sensors shall be located at the bottom of a vehicular
vertical lift gate.
c. One or more contact sensors shall be located at the pinch point of a
vehicular vertical pivot gate.
d. A hardwired contact sensor shall be located and its wiring arranged so
that the communication between the sensor and the gate operator is not
subject to mechanical damage.
e. A wireless contact sensor such as one that transmits radio frequency
(RF) signals to the gate operator for entrapment protection functions
shall be located where the transmission of the signals are not obstructed
or impeded by building structures, natural landscaping or similar
obstructions. A wireless contact sensor shall function under the intended
end-use conditions.
f. One or more contact sensors shall be located on the inside and outside
leading edge of a swing gate. Additionally, if the bottom edge of a swing
gate is grater than 6 inches (152 mm) above the ground at any point in its
arc of travel, one or more contact sensors shall be located at the bottom
edge (refer to page 7).
g. One or more contact sensors shall be located at the bottom edge of a
vertical barrier (arm).
h. Only Use Miller Edge Model MGR20 or MGS20 edge sensor to comply with
UL325
!WARNING! Not Following these instructions may cause severe injury or death.
