HVG Series, Hydraulic Vertical Lift Gate Operators

Application Chart

To offer the greatest flexibility in design, we have created several models of
the HVG operator series. The chart below should help you through the
several choices. Standard lifting towers are 24' high. If your design calls for
heavier than standard gate weights, taller lifting towers are available. (Coun-

terweight materials are not included with the operators.)

HVG 420 Series, 10" square
steel lifting towers.

HVG 420 EX

HVG 460 Series, 12" square
steel lifting towers.

HVG 460 EX

This operator series will lift gates, of
any construction, up to 1,000
pounds. The speed of this operator is
one foot per second.

This operator will also move 1,000
pound gates, but travels at two feet
per second.

This operator series will lift gates, of
any construction, up to 2,000
pounds. The speed of this operator is
one foot per second.

This operator will also move 2,000
pound gates, but travels at two feet
per second.

SPECIAL NOTE: HVG Operators are available in D.C. battery operated versions.

Battery chargers are included and battery packs are available in 2 battery or 4 battery
versions to provide many cycles of operation.

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.

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.
