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 in 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 into 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

1. Follow the local building code to determine the required depth of the concrete pad.
2. Pad measurements recommended by Viking Access Systems are at lease 20” long,
20” wide and 30” deep to ensure the stable operation of the operator, and a
minimum of 6” above level grade to avoid any flooding of the machinery.
4. Provide a sufficient number of conduit pathways for all low power accessories
such as loop detector leads, maglock, non-contact sensors, contact sensors, safety
and other commands.Also provide conduit for the power supply (either 110 or
220 VAC). Extend the conduit the recommended height of 1” above the level of
the concrete pad. Install all conduit in the shaded area shown above.

INSTALLATION
CAUTION - If mounting bar is not welded to
a frame member that runs the full length
of the gate, the gate operator may
damage the gate. Do not weld the bar or
backing plate to a few pickets.

STEP 1
Release the clutch (see page 7). Cut the
extension arms according to the desired plan
of installation (Figure A on page 10).
Note: Leave some additional material when
cutting the extension arms to allow for
additional adjustment.

Remove Excess
Extension Tube

STEP 2
Position the pieces of the articulated arm
with the gate in the closed position. Ensure
that the dimensions correspond to the chosen
plan of installation. Use C-clamps or tack-weld
pieces to aid in the pre-installation process.

STEP 3
With the clutch released, move the gate
manually from the completely open to the
completely closed position. Verify that:
A. The gate and arm combination can
provide the desired operation.
B. The arm does not bind in its movement,
especially in the open position.
Note: The total travel angle of the primary arm
on the output shaft determines the speed of the
gate operation. The smaller the travel angle,
the quicker the gate will open and close.

STEP 6
Check the Clutch adjustment. The Clutch is
shipped factory adjusted. The clutch must be
tight enough to prevent slippage in normal
operation.
Check the tightness of the Clutch:
A. Remove the Clutch Key from the clutch.
B. Attempt to move the gate by hand.
C. If slippage occurs:
1. Loosen the Locking Handle 180°
2. Tighten the opposite bolt.
3. Tighten the Locking Handle 180°
4. Check the tightness of the clutch again.

The Gate Operator requires a single phase AC
line to operate and charge the batteries.
1. Turn off the main switch or breaker for
the power line being used.
2. Move the selector switch on the Incoming
Voltage Selector to the proper position
(115 for 110 to 120VAC, 230 for 200 to 240VAC).
3. Connect the incoming power wires to the
terminals as shown in the illustration.
4. Turn on the main switch or breaker once
the installation is ready for final
adjustments.
5. To verify that there is AC power to the
system, check that the ‘Charger’ LED on the
Control Board is on.
Tips for proper ground installation
A good ground in a gate operator
installation will minimize or prevent damage
to the operator cause by natural events such
as lightning strikes.
The following will provide a guideline for
proper grounding:
1. Use a ground rod to provide a ground
reference.
2. Consult your city code and be aware of
under-ground services in the site of the
gate operator to prevent inconveniences.
3. Use always a single bonding point for
grounding.
4. All ground wires must be as short and as
thick as possible.
5. Prevent unnecessary turns or loops in all
ground wires.

WARNING – Consult the installation instructions from the loop detector manufacturer. The following
statements are provided as a guide but different requirements may be required by the
vehicular loop detector manufacturer.

Guidelines for Vehicular Loop Detector Installation
1. Prevent sharp corners in the geometry of the loop sensor.
2. Install the appropriate number of turns for your loop geometry based on the loop perimeter. Use
Table C (below) as a guide.
3. Use XLP (cross-linked-polyethylene) type of wire. This wire reduces the effects of moisture and
other environmental events in altering the functionality of the vehicular loop detector.
4. Twist the lead wire at least 6 turns per foot.
5. Use BACKER-ROD to minimize damage to the loop detector wire prior to using the sealant.
6. Place the loop detector wire and adjust the sensitivity of the vehicular loop detector unit in a
way to minimize the effects of the gate over the loop detector wire.
IMPORTANT – Some of the following parameters may affect the proper functionality of the
vehicular loop detector (consult the installation manual and the manufacturer of the
vehicular loop detector).
• Gate size,
• Number of turns in the loop sensor wire;
• Distance from the loop sensor wire to the gate either at the open or close position.
