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 least 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.

GATE OPERATOR INSTALLATIONGATE OPERATOR 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.

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 4

Upon observation of the satisfactory
arrangement of the articulated arm and
bracket, weld all pieces securely. Paint the
arm to protect it from rusting.

STEP 5

Upon test of the installation, loosen the
clutch and rotate it until it lines up with the
notches in the Output Shaft. Insert the
Clutch Key.

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°
Tighten the opposite bolt.

2.

3. Tighten the Locking Handle 180°

4. Check the tightness of the clutch again.

NOTE – For proper operation of the Clutch,

keep the gap between the Clutch halves
even when adjusting (the Clutch will have
to be removed from the Output Shaft in
order to adjust the Release Handle bolt).

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.

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.

IMPORT

ANT – 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.

When connecting the Radio Receiver carefully verify the proper connections.

The maximum voltage that the control board provides for external accessories is the
maximum voltage of the battery, which is about 28 volts.

In the event of an electrical short in the power to the accessories, the board will
protect itself by shutting down and will remain shut down until the short is corrected.

The control board provides two modes of
operation that a radio receiver can control
the gate:

Open-Stop-Close

1. By having the radio receiver connected as
illustrated and with the Hold Open Timer
OFF (see page 29):

Every command of the radio transmitter
will control the gate as follow:
a) First command opens the gate,
b) Second command stops the gate and
c) Third command closes the gate
d) Any subsequent commands will continue

in the same order to control the gate.

This type of configuration is not
recommended for a commercial
installations.

Open Only

2. By having the radio receiver connected as
illustrated and with the Hold Open Timer
ON (see page 29):

Each command of the radio transmitter is
ALWAYS AN OPEN COMMAND to the gate.

Note: All controls are normally open.

Auto-Open Feature

The Auto-Open feature in Viking Gate Operators enables the following functionality in
the event of power failure:

a) Open the gate in case of power failure (120 or 220 VAC).

b) Keep the gate at the open position as long as the there is no power.

c) Resume to normal operation when the power has been restored.

The Auto-Open feature allows proper operation while opening in case of power failure
for the following devices:

• All accessories,

• All safety devices,

• All entrapment protections.

The only operation that can not be executed while opening in case of power failure is to
CLOSE the gate.

To enable the Auto-Open feature : Use the
“jumper” provided and place it on the pin­header of JP3, on the terminals close to C35 as
the illustration indicates.

Once you put the “jumper” on the control
board the “Check Motor” light will come on
indicating that the Auto-Open feature has been
enabled.
