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 required 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 square 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 square 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 "square" 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 Operation: 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 Operation: 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

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 adjust 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 equal 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" square (10 square 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

required. 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.

#5

#4

#3

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:

Supplying a gate operator with the right electrical service is crucial to the way the performance of
the operator the life of its electrical components. If the wire size used is too small, the voltage loss—
especially during motor starting—will prevent the motor from attaining its rated horsepower. The
percent of horsepower lost is far greater than the percentage of the voltage loss. A voltage loss could
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
undersized wires, except to replace them; therefore it is much more economical to choose a sufficient
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 maxi­mum allowable control wiring dis­tance. If the location required ex­ceeds 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 compo­nent 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.

HTG 320-2 700 psi

Front View

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.

Connection Diagram

Voltage loss over distance is caused as a function of control amperage multiplied by the resistance of
the wiring, and may be expressed: Voltage loss = (wire resistance) X (control amperage). This
limits pushbutton control wiring to the following schedule:

16 ga. wire= up to 125 feet max 12 ga. wire = up to 300 feet max

14 ga. wire = up to 200 feet max10 ga. wire = up to 500 feet max
For applications requiring pushbutton controls from a long distance, or circuits of limited current,
order the factory modification, long range interface. The following schedule indicates the improved
control range using the long range interface:

16 ga. wire = up to 50 miles 20 ga. wire = up to 19 miles

18 ga. wire = up to 30 miles 22 ga. wire = up to 12 miles

FOR BEST PERFORMANCE

USE 20 GAUGE WIRE OR LARGER

Be certain to remove factory-installed jumper (#2 to #4) and also verify that no other external stop
button is connected at #2 and #4.

Master/Slave Interconnection Instructions

Master/Slave Interconnection InstructionsMaster/Slave Interconnection Instructions

FOR ALL MODELS EXCEPT: HTG 320

Operation of two Hy-Security gate operators as a master/slave pair is simply a matter of correctly
interconnecting the two control circuits. Join the following four wires from the master operator to the slave:

Terminal #1 master to terminal #1 slave,
Terminal #3 master to terminal #3 slave,
Terminal #4 master to terminal #4 slave,

*Terminal #10 master to terminal #10 slave

All stop control inputs must be connected to the master operator only. The slave operator must not have any
connection between terminal #2 and terminal #4, such as a stop button or jumper.

*On DC battery powered operators, interconnect the black wires (-) to the on/off switch instead of the #10
wires. This prevents one operator from powering the other when the disconnect switch is off.

For assistance call your Distributor.

Conversion of Primary Operator VoltageConversion of Primary Operator Voltage

Conversion of Primary Operator Voltage

Conversion of Primary Operator VoltageConversion of Primary Operator Voltage

These instructions do not apply to conversions from single phase to three phase

or vice versa. Conversion from one phase to another is not recommended.

Steps required to convert the voltage of an operator within the same phase:

1. The overload must be changed to match the motor current at the new operating voltage.
To do this, remove the overload device from the contactor by loosening the three screws T1, T2 and T3 on the
contactor. Remove all the wires on the overload and replace them exactly the same position on the new
overload. Mount and tighten screws firmly. Be certain the new overload is adjusted to match the motor
nameplate amps that correspond to the new voltage. Note that the existing overload has sufficient range to
accommodate adjustment from 208 volts to 230 volts or vice versa.

2. The primary tap on the control transformer must be changed to the new voltage.
This is accomplished by first reading the label on the top of the control transformer to determine which color
primary lead corresponds to the new voltage to be used. Disconnect the existing primary lead (Caution: Do
not disconnect the primary “Common” lead) and reconnect the primary lead to the same location.

3. The power leads to the motor must be reconnected in the motor junction box to match the new voltage.
You must remove the cover from the junction box on the electric motor. Reconnect the primary leads in the
new configuration shown on the motor nameplate that matches the new voltage. Note this step does not need
to be performed for conversion between 208 volts and 230 volts.

4.The operator must be re-labeled to indicate the new voltage.
Apply new labels to the operator so that the correct primary voltage is indicated.

5. To add a heater you need the following parts: (includes thermostat wire and all mounting hardware):

120 VAC AEKHE 120 250
208-240 VAC AEKHE 240 250
480 VAC (includes relay) AEKHE 480 250

Installation Instructions For Gate Reversing Sensing EdgeInstallation Instructions For Gate Reversing Sensing Edge

1. Securely bolt the edge sensor to the edge of the gate. The edge should line up with the lower corner of the

gate frame.

2. If the reversing edge is to wire directly to the gate operator:

A. Locate a mounting position for a curl cord attatchment, or retracting cord reel holder where there will be
no possibility of the cord rubbing on the moving gate panel.

B. Attatch the cord to the gate in a position that is roughly near the position of the automatic operator,
when the gate is closed.

C. Route the wires to the leading edge of the gate and join to the wires of the reversing edge. Wirenut and
thoroughly tape the connections so that they are not prone to vibrate loose.

D. Join the fixed end of the cord reel or curl cord directly to terminal numbers 1 and 6 inside the control
box of the operator.

3. If the reversing edge is to transmit to the gate operator:

A. Mount the reversing edge transmitter (Multi Elmac Model #3022, or equivalent) onto the gate panel
near the upper corner of the leading edge of the gate.

B. Join the wires of the reversing edge to the two terminals inside of the edge transmitter. Set a unique
code on the “DIP” switches inside the transmitter. Remount the cover of the transmitter and tighten the
screws firmly so that no water will leak inside.

If a receiver for the reversing edge has been prewired inside the operator, proceed directly to step #3D.

C. Mount a commercial style radio receiver* (one with a connector for an external antenna) on the inside
of our operator enclosure. Connect the 24 Volt supply wires to terminal numbers X1 and 10 on the
terminal strip. Connect the radio contact wires to terminal numbers 1 and 6 on the terminal strip.

D. Mount an external antenna onto the top of a fixed post of the fence near the operator. Connect the
antenna into the socket on the radio receiver.

E. Set the “DIP” switches in the receiver to match the same code used in the edge transmitter.

*If there is also to be a radio receiver for a hand held transmitter to operate the gate, be certain to use a two
channel commercial receiver.

4. Test the operation of the reversing edge to be certain that it is functioning. Advise the user of the gate to be

certain to retest this vital function weekly.

The procedure for manual operation of the vertical
lift gate in case of power failure or a serious
malfunction is as follows:

1. Turn off all electrical power to the controller.

2. Remove the lower access covers on both posts.

3. Remove the Allen head bolt in the three inch
sprocket at the end of the hydraulic motor in each
post. The gate will now operate like an old "sash
weight" type window, with friction as it's only
resistance.

4. Be certain to tie a rope to the bottom of the gate
panel so it can be pulled down again.

5. When the automatic operation is again ready,
reverse the above procedures.

After proper installation of the vertical lift gate operator, very little maintenance will be required to insure long
and trouble free operation.

MONTHLY:

1. The primary maintenance procedure will be to maintain the drive chain tension. The tension can easily be
checked: Operate the gate to the full open position. Grasp the chain that connects the bottom of the bogie to the
bottom of the weight cage and pull it outward. The chain should always feel somewhat taut, it should never be
loose. This is especially important when the operator is new.

A. To expose the chain tension adjustment area, remove the middle access cover (about three feet above

the ground) and raise the gate to full open.

B. Locate the two threaded rods connected to the top of the weight cage. Loosen the locking nuts on top

of the cage and tighten the nuts on the top inside of the cage. Be sure to tighten the nuts an equal amount

in order to keep the load balanced between the two chains. Tighten the lock nuts.

SEMI-ANNUALLY:

1. Each king post has four bearings with grease fittings. These should be greased semi-annually.

2. Check the balancing cable for correct tension. They should neither sag nor greatly compress the spring at the
top of each post. Also inspect the cables for fraying or snagging, especially where they lay on the sheaves when
the gate is closed.

3. Inspect the cable sheaves to make certain they rotate freely.

4. Check the oil level in the reservoir at the hydraulic pump. It should always be at least 3/4 full. Generally the
oil level should not change. A change would indicate a leaky hose, a serious problem that must be found and
corrected.

5. Apply a light oil to all the chains.

Hydraulic System

Fluid Level: Under normal conditions, hydraulic systems do not consume oil. Before adding any oil, check the

system thoroughly for leaks. Remove the bright metal plug in the tank, fill to plug level, then replace plug. We
recommend our Uniflow hydraulic oil, part number H-004, which is sold in one gallon containers by our distribu­tors. Automatic transmission fluid may be used, although its performance in cold weather will be sluggish unless
the operator is well heated. Do not use brake fluid.

Look for leaks: Occasionally there may be slight seeping at the fittings after some usage. Tightening of the fittings

will usually correct the problem. If the leaking persists, replace "O" rings, fittings or hoses, if required. No further
leaks should occur.

Oil Change: A hydraulic system does not foul its oil, unlike a gas engine, so oil changes do not need to be frequent.

Rather, heat breakdown is the main concern in a hydraulic system. If the unit is subjected to high use, especially in
a warm climate, change the oil more frequently. In general, we recommend draining the reservoir and replacing the
oil at five or ten year intervals.

There are several ways to change the hydraulic oil, depending on the type of operator being serviced. If you
don’t know how to drain the oil, contact your distributor for directions. Refill with new Uniflow hydraulic oil
(available from your distributor). To avoid overfilling, never pour into the port where the black breather cap is
located. Instead, remove only the bright metal plug in the tank. Slowly pour the oil into the tank until the oil is
within one inch of the filler port. Replace the plug and wipe up any spilled oil.

Cold Weather:

1. Check that your reservoir is filled with Uniflow high performance oil.

2. Ice can partly or totally jam gate operation. Check by operating the gate manually.

Electrical Controls

Before servicing, turn off power disconnect switch

No routine maintenance is needed for the electrical system or controls. If the environment is very sandy or dusty, seal
all holes in the electrical enclosure. Blow dust out of the electric panel with compressed air. A qualified electrician may
troubleshoot with the aid of the electrical drawings in Appendix 4.

If it is necessary to call a distributor for assistance, be sure to have your model and serial number ready. Other helpful
information would include the name of the job, approximate date of installation, and the service record of the operator,
especially any work that has been done recently. Be prepared to describe as exactly as you can what the machine is or
is not doing. Describe any unusual sounds or location of oil leaks.

How to Adjust the Pressure Relief Valve: To check your relief valve setting, first disconnect one of the hoses.

Run the operator either open or closed (the gate will not move with the hose disconnected. The relief valve is found
on the rear of the hydraulic power unit. It has a hex adjusting head and lock nut. To adjust, loosen the lock nut and
screw the threaded bolt clockwise for increased pressure, counterclockwise to decrease pressure.

MODEL FACTORY SETTING

111 Series 750 psi
SS, E Models 1000 psi
EX Model 1300 psi
444 Series 1300 psi

Do not attempt to use the relief valve as an entrapment protection device. Photocells or gate edges are the best
methods to protect pedestrians and reserve power to the drive gate.
