INSTALLATION INSTRUCTIONS
HVG VERTICAL LIFT GATE OPERATOR
1. The concrete footings for the vertical lift posts must be very substantial. An engineer should be retained to
specify the appropriate footing considering the soil conditions, size of the gate and wind load.
2. The anchor bolts are supplied by Hy-Security as a pre-welded cage and must be installed before the post footings
are poured. Contact Hy-Security if the anchor bolt cages are re uired in advanced of the posts.
3. Place a nut and flat washer onto each of the threaded anchor bolts protruding from the post foundation. Screw
the nuts down until only two or three threads are showing under the nut. Lay the washer on top of each nut. Verify
that you have enough threads left to project through the base plate and allow for another washer and nut on top.
4. Mount the HVG posts onto the foundation. The two HVG posts must be s uare with each other across the
opening. The removable access panels are designed to face the protected side of the opening. The HVG post with
the rotary limit switch should be on the same side of the roadway as the controller panel.
5. Place a second washer and nut onto each threaded anchor bolt to lock the posts in place. Before final tightening,
it is critical to verify that the posts are s uare with each other and that are perfectly level and plumb. Use a plumb
bob or a six foot minimum level to assure the posts are plumb. Use the locking nuts to achieve "plumb" in both
directions and twist the posts (notice the curved slots in the base plate) to achieve "s uare" with the other post.
6. Mount the controller box on the wall or fence line near the HVG post. The controller panel should be within
50 feet of the post that contains the rotary limit switch.
7. Entrapment Protection - Minimum Safeguards:
A. Since automatic gates are not intended for pedestrian use, always install a separate pedestrian walkway
and access gate. Install signs which direct persons to use the pedestrian gate, and to not enter through
the vehicle gate.
B. Be certain that the gate has been constructed such that the opportunity for persons to reach through any
opening have been minimized.
C. Be certain that all access controls are located at least a six foot distance from the gate, to reduce the
possibility of any attempt to reach through in order to operate the gate.
D. Be certain to mount at least two of the enclosed 8 1/2 x 11 warning placards on each side of the gate
to warn users of the hazards of a power operated gate.
E. Button Station peration: Be certain to mount a warning placard near each button station that warns
that the area must be clear before operating the gate. If there are no entrapment protection sensors to
guard the closing operation of the gate, the push button station must be wired for constant hold
operation only. This is achieved by cutting jumper wires in the control circuit, see drawing E63VT2.
F. Automatic peration: Entrapment protection sensors must be installed to guard the closing of the
gate. Install photo electric eyes, or attatch edge sensor to create a reversing function. All sensors
guarding the closing direction connect to terminals #1 and #6 in the control box.
Caution: Vehicle detectors are not entrapment protection sensors.
8. Connect appropriate power wiring. Be certain to oversize supply conductors to allow for voltage drop,
especially for single phase machines. Follow the wire schedules (drawing #E16a, b). Route conduit to the control
box. Wirenut the supply power wires to the loose wires at the back of the on/off switch. Be certain to connect a
ground wire. Page 1 of 2 01/4/01 HV20a

8/2/00 HV21
HVG LIMIT SWITCH, SETTING / WIRING INSTRUCTIONS
1. For all HVG operators, eight conductors are required from the limit switch to the control panel.
2. The limit switch is pre-set at the factory, to limit full travel in both directions. Fine tuning may be required in
the field, to suit conditions.
3. To ad ust the limits:
a. Loosen the cam clamp screws.
b. Depress the pinion gear, near the switch, engaging the gear teeth.
c. Rotate the cam to trip the limit switch, several inches before full gate travel, to allow the gate to
decelerate.
d. Tighten clamp screws.
e. Repeat steps "a" and "d", for each limit switch.

9. Connect wires between the rotary limit switch and the controller box according to drawing HV21. Connect the
hydraulic hoses to the appropriate sockets. See drawing HV22 and pay close attention to the color coding on the
hoses. The colors should match after hook-up. Run the operator to verify correct functioning. If the hydraulic hoses
were inadvertently reversed, the gate will move in the opposite direction than commanded. If the limit switches
were connected backwards, the operator would not stop when the gate reached its full travel. Never reverse wiring
to the push button station. Replace the plug in the hydraulic reservoir fill hole with the vent cap provided.
10. Remove the plastic shipping plug on the pump manifold near the motor and replace it with the vent cap
supplied.
11. Run the operator to verify correct functioning. It is normal for the bogies to operate slightly out of
synchronization.
12. If the motor runs but nothing moves, close the by-pass valve located near the electric motor or reverse any two
poles of a three phase motor.
13. Temporarily place the gate panel into the opening on the outside side of the property. Before mounting, verify
that the width of the gate does not exceed the dimension between the angle bogie guides. If the gate panel is too
wide it will interfere with the smooth operation of the gate operator and may actually cause damage to the top
covers of the HVG posts.
14. Remove the cap screw on the release sprocket located on the hydraulic motor in the bottom of each post. The
lifting bogies are now free for adjustment so that they may be centered on the gate panel's vertical edge. Mount
the gate panel to the bogies while being certain that no tension is applied that may cause a binding action during
travel. Replace the cap screws in the sprockets. Be sure that they penetrate through the hole in the sprocket and
that the heads are fully seated.
15. Install the 1/8 balancing cables using the supplied cable. Slip the ends with the loops into the upper eye bolts.
Run cables under the white sheaves on the lifting bogies, across the face of the gate panel, over the opposite sheaves
and to the bottom eye bolts. Use the cable clamps that are supplied to hold the cable in minimum tension. The cables
should not hang loose, but the compression spring at the upper eye bolt should not be collapsed. Cut off excess
cable.
16. The vertical lift must be fully counterweighted. The counter weight for each post should be e ual to one half
of the total weight of the gate panel. Remove the middle access cover located three feet above the ground. Operate
the gate until fully open.*(see note at end of section) Stop the gate and shut power off. Load the counter weights
into the weight cage which should now be visible through the access cutout. Sheared steel plate 1/2" or 3/4" thick
and 7" s uare (10 s uare for HVG 460), makes an easy to handle counterweight material. It is easy to find and
makes fine tuning a snap. NOTE:(one 7" x 7" x 3/4" plate weighs about 10 pounds and one 10 x 10 x 3/4 plate
weighs 20 pounds.)
17. Operate the system a few times to verify that everything is working properly. Set the open and close limits as
re uired. After testing the basic functions, connect any extra external control wiring and re-test for proper
function.
*NOTE:
Since there is no counter balance for the initial operation, it may be necessary to assist the gate in opening. If necessary, use
a fork lift, block and tackle or manpower for this operation. If the hydralulic pump runs and the gate does not move during
this operation, no harm is done. The pump will simply by-pass through the relief valve and send the fluid back to the tank.
18. Be certain to test the function of the entrapment protection sensors before completion.
For assistance, contact your local distributor.

Field Hose Measurements for
HVG and HRG Operators
When field measuring for the necessary hose length to order, the following may be helpful:
There is little room in the base of the HRG or the HVG operators and limited room in the
control/power panel, therefore, your field measurements must be very accurate when
calculating the length of the necessary hydraulic hoses. If your dimensions are too little, you
will not reach the connections, if your measurements are too long, you will have trouble
finding space for the excess hose.
Remember that two hoses are needed for each motor or each cylinder. This means that you
need four hoses when you are dealing with a HVG operator and also when you are installing a
HRG 222 (pair) operator.

Roadway
Be sure to measure accurately the following distances: (the best way is to pull a cord through
the conduit, mark it, and then measure it.)
1. The bottom of the pump/control panel to the bottom of the trench.
2. The total distance across the trench.
3. The distance back up to the bottom of the operator.
4. Add approximately 6" for the hoses to reach up into the operator.
5. Add approximately 24" for the hoses to reach up into the power/control panel.
The part numbers for the hoses are:
1/4" hose for HRG: H SFHO 004 SW
3/8" hose for HVG: H SFHO 006 4216

Supplying a gate operator with the right electrical service is crucial to the way the performance of
theoperatorthelifeofitselectricalcomponents. Ifthewire size used is too small, the voltage loss—
especially during motor starting—will prevent the motor from attaining its rated horsepower. The
percentofhorsepowerlostisfargreaterthanthepercentageofthevoltageloss. Avoltagelosscould
also cause the control components to chatter while the motor is starting, substantially reducing their
life due to the resultant arcing. There is no way to restore the lost performance resulting from
undersizedwires,excepttoreplacethem;thereforeitismuchmoreeconomicaltochooseasufficient
wire size at the initial installation.
The tables on the following page are based on copper wire and allow for a 5% voltage drop. The
ampere values shown are the service factor ampere rating (maximum full load at continuous duty)
of the motor.
Always connect in accordance with the National Electrical Code, article 430, and other local codes
that may apply.
The maximum distance shown is from the gate operator to the power source; assuming that source
power is from a panel box with adequate capacity to support the addition of this motor load. The
values are for one operator, with no other loads applied to the branch circuit. For two operators
applied to one circuit, reduce the maximum allowed distance by half.
Use this chart to determine maxi-
mum allowable control wiring dis-
tance. If the location required ex-
ceeds the distances listed on the
chart at the right, addition of a long
range interface will be neccessary.

The relief valve can be found on the back side (gate side) of the hydraulic power unit. It is the only compo-
nent located here and has a hex adjusting head and lock nut. To adjust setting, loosen the lock nut screw the
threaded bolt CW for increased pressure, turn CCW to decrease pressure.
Pressure relief valves are preset at the factory to utilize maximum available horsepower. The relief valve can
be lowered to smooth starting if necessary. This is most easily done by decreasing the pressure until the gate
operation slows, and then increasing the pressure just enough to provide normal gate speed.
It must be understood that if you reduce the pressure setting, you will lose horsepower to move the gate if
additional resistance (old gate hardware, snow and ice, etc.) is encountered.
Do not attempt to use the relief valve as an entrapment protection device. A photo eye or a gate edge
is the best method to protect pedestrians and reserve power to drive the gate.
