The Smart Touch Controller (Standard)
This is the brain of the all Hy-Security’s automatic operators. Truly high technology, but is also very
rugged to reliably serve in the harsh environments that exist in the real world. The Smart Touch Controller
is also very smart and can quickly be configured by an installer or user to adapt to about any functional
requirement of a specific site. All system settings are performed with the use of just four programming
buttons and an LCD display. The Smart Touch Controller has no switches of any type to set. An RS232
port is for external communication is standard. The system also has a real time clock and an EEPROM to
record system events. The log of events can be downloaded from the RS232 port with a PC computer or a
PDA with the Palm OS. Our optional vehicle detector modules set a new industry standard by
communicating a host of valuable performance data to the microprocessor in the Smart Touch Controller
via a serial data stream, allowing user-friendly diagnostics.
DC 24-Volt UPS Operators (Optional Version)
These gate operators function from 24 Volts DC all of the time to achieve a true UPS system. Our
Uninterruptible Power Supply is the most certain way to know that your gate will work when the AC
power fails. This system features fully sealed maintenance free batteries in a separate insulated and
ventilated enclosure.

Important Information – Review Before Installation
Automatic gate operators provide convenience and security to users. However, because these
machines can produce high levels of force it is important that all gate operator system designers,
installers and end users be aware of the potential hazards associated with improperly designed, installed
or maintained systems. Keep in mind that the gate operator is only one component of the total gate
operating system. It is the joint responsibility of the specifier, designer, purchaser, installer and end user
to verify that the total system is appropriately configured for its intended use. All parties should be
informed that entrapment in a moving gate could cause serious injury or death.

-Take Note-
Important Instructions for Gate System Designers & Installers:
WARNING: To reduce the risk of serious injury or death, read and follow all instructions in the
gate operator handbook and on the warning labels.
Install an Automatic Gate Operator only When:
Y The entry is configured for vehicular use only. Pedestrians must be directed to a
separate walk-through entrance.
Y The Warning signs that have been supplied with this operator must be installed,
in manner clearly visible, in the area of both sides of the gate.
Y All exposed pinch points, are guarded. To reduce the risk of entrapment, the
gate must also be installed so that enough clearance is provided between the
gate and adjacent structures both when opening and closing.
Y The controls that operate the gate have been mounted far enough away from the moving gate such
that users cannot touch the gate while operating the controls. All easily accessible controls must
have a security feature to prevent unauthorized use.

Installation and Maintenance Manual
Install An Automatic Swing Gate Operator Only When:
Y The gate moves freely in both directions. Never over-tighten a clutch or pressure relief
valve to compensate for a stiff moving gate.
Y The operator will not swing the gate into a public access area.
Y The operator will be properly electrically grounded and the intended supply voltage matches
the voltage label on the operator.
Y The operator controls will be located in a clear line-of-sight to the gate. Radio controls and
other remote access controls must be connected only to the Remote Open input.
Y The required external entrapment sensors will be installed. Be certain to carefully review
the instructions for placement, installation and adjustment of these external entrapment
sensors. External entrapment sensors must function to reverse the movement of the gate
in both the opening and closing directions. If edge (contact) sensors are used, they are
to be located on the inside and outside leading edge of the swing gate and along the bottom
edge of a swing gate that is greater than 6” above the ground. If photo eyes or other noncontact sensors are used, they are to be mounted in locations most likely to guard against
entrapment. A combination of contact and non-contact sensors may be used, but all must
be recognized components under the UL 325 standard. See pages 32 and 33 for details on
the requirements.
Y If the Entrapment protection is provided by a continuous pressure actuation control, a
placard must be installed next to the control station stating “WARNING” – “Moving Gate has
the Potential of Inflicting Injury or Death - Do Not Start Gate Unless Path is Clear.”
Additionally, no other activation device shall be connected and an automatic closing device
of any kind shall not be used.
Y The automatic operator is labeled as appropriate for both the type and UL usage class of
the gate.
Class I: Intended to serve single to four family residential uses
Class II: Multi-family use, or any application intended to serve the general public
Class III: Commercial applications not intended to serve the general public
Class IV: Highest security. Security personnel prevent unauthorized access

Installation and Maintenance Manual
Important Information For Gate System Owners & Users
WARNING: To reduce the risk of serious injury or death, read and follow all instructions in the
gate operator handbook and on the warning labels.
Save These Important Owner and User Instructions:
(Installers – be certain to instruct the owners and users about the following items)
Y Automatic gates are for vehicular use only! Provide walkways and signs to direct
pedestrians to a separate walk-through entrance. Because an automatic gate can start at
any time without warning, always keep people away from the area of the gate.
Y The Warning signs that have been supplied with this operator must remain installed, in a
manner clearly visible, in the area of both sides of the gate.
Y Never allow children to use or play with controls that operate the gate. Keep all remote
controls, especially radio transmitters, away from children.
Y Teach all users how to turn off the electric power and how to release and move the gate
manually. Use the manual release only when the gate is not moving.
Y Test the function of the gate operator monthly. The gate MUST reverse its direction of
travel upon contact with a rigid object, and/or stop upon a sensing a 2
activation prior to reaching a full travel limit. Also test for the normal function of any noncontact sensors. If the gate system employs the use of a transmitting edge sensor, be
especially certain to test and replace its battery on a routine basis.
Y KEEP AUTOMATIC GATES PROPERLY MAINTAINED. Have a professional gate
installer perform routine tests of the entrapment protection sensors, such as photo eyes
and gate edges. Also, make all necessary repairs to the gate hardware to keep the gate
running smoothly. Failure to adjust and test a gate operator properly can increase the risk
of injury or death.
Y In addition to appropriately placed external entrapment sensors, ask your installer to
reduce the setting of the pressure relief valve to the lowest setting allowable that reliably
operates the gate. This valve controls the force of the operator, and the sensitivity of the
inherent reversing sensor.
Y Do not attempt to disable the Warn Before Operate buzzer, except in Class IV
restricted access locations. This buzzer provides an alert that the gate is about to
move.

Installation Preparation Checklist
1. Read all of the instructions, especially the
Important Information at the beginning of this
manual, before you attempt installation. This
section is focused upon mechanical installation.
For electrical setup, skip to the section on
system configuration and use of the Smart
Touch Controller.
2. Check to see that the mounting slab is
the right size and ready to have an
operator attached. Also check that
electrical conduits are correctly located
to enter the operator base. Hy-Security
recommends the slab reaches below the
local frost line and is poured together
with supporting post or pilaster.
NOTE: The backing post/column, (provided by
others) must accommodate all of the "tip
over" loads imposed by the gate panel.
Installation Process Overview
• Mount the control box and connect all
conduit fittings.
• Mount the operator post.
• Install all accessories such as: vehicle
sensing loops, access control devices,
gate edge sensors or photo eyes.
• Pull all wires and hoses into conduits.
Note: HRG 220 comes with up to 40’ of
hose for the HRG 222 with up to 100’ of
hose, however, you must advise the
factory on the accurate amount of hose
desired or it will not be shipped with the
operator.
• Test the basic operator functions.
• Mount the gate panel and make fine
adjustments.
Installation and Maintenance Manual

Installation and Maintenance Manual
Field Hose Measurements for HRG Operators
Note: HRG operators are usually shipped without the hoses needed to complete the system.
Hy-Security will make these hoses in custom lengths as required, attach the quick disconnect fittings and
pre-charge the hoses with hydraulic fluid. The use of pre-charged hoses is important to avoid the
introduction of air into the system.
When field measuring for the necessary hose length to order, the following may be helpful:
1. There is little room in the base of the HRG operator post 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.
2. Remember that two hoses are needed for each cylinder. This means that you need four hoses when
you are installing a HRG 222 (pair) operator.
1) 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.)
a) The bottom of the pump/control panel to the bottom of the trench, plus 24”
b) The total distance across the trench.
c) The distance back up to the bottom of the operator, plus 6”
1) The part number for the hoses is:
1/4" hose for HRG: HSFHO 004 SW
The HRG 220 includes up to 40’ total length for the two hoses required.
The HRG 222 includes up to 100’ total length for the four hoses required.
For assistance call your distributor.

Installation and Maintenance Manual
Detailed Installation Instructions for HRG Swing Gate Operator
1) Mount control box and connect all conduit fittings.
a) Mount controller box within 100’ of the gate operator, preferably within 20’. If installing the DC
version of the operator, mount the battery power supply very near the controller enclosure
because of the high current demand by the DC motor – See the Two Part operator section.
b) Attach all electrical conduits as required, note the diagram below and see step number 3.
2) Mount operator post
a) Using 5/8" – 3/4” anchor bolts, mount the 12”
square operator base with 1” clearance between
the base and the backing post or wall. The gap
between the operator post and the backing post
will be 3 1/2”. It is important that the finished
installation be plumb and true. Use shims if
necessary to level the operator base.
b) Attach the top of the operator to the backing post
or supporting wall, using the bracket provided.
The attaching bracket "sleeves" inside the top of
the operator post. Note! The backing
post/column, (provided by others) must
accommodate all of the "tip over" loads
imposed by the gate panel.
15
Installation and Maintenance Manual
3) Typical conduits required at the control panel
a) High voltage wires: (120, 208, 240) single
phase or (208, 240, 480) three phase
Note: 120 VAC not available on 2HP models
b) 2” conduit to the hydraulic post(s) for hoses.
c) 3/4” conduit to the post(s) for limit switches.
d) Access control wires (Keypads, telephone
entry systems or any access control devices)
e) Loop wires for vehicle detectors
f) Other accessories such as warning lights etc.
4) Mount or install all control wiring such as
loops, access control, and entrapment
protection sensors. See detailed instructions
5) Pull and connect all wires and hydraulic hoses
a) Pull four wires, 18 gage minimum, for the limit switches from control panel to
junction area in the base of the operator post(s). This may be either by
underground conduit or by a seal-tight conduit into the side of the base.
b) Remove the lower cover (at 2’ height) on the post(s) to expose the limit
switches and connect the limit switch wires. The open limit switch is on the
left and lower than the close limit. Connect these wires to the control box at
the five pole terminal strip marked open limit and close limit.
c) HRG operators normally do not ship with the hydraulic hoses included, until
Access panel at
operator base
the exact length is specified by the installer. See page 14 and verify the
correct length before ordering.
d) For protection, tape the ends and pull the hoses through the 2" conduit from
each post to the controller box. Connect the hoses to the couplings, being
certain to match the color coded ends. Also be certain that the connectors
are firmly snapped together.
e) Remove the blue plastic shipping plug on the pump and replace it with the
vent cap that is provided.
f) Connect the electrical power wiring to the loose wires from the On/Off
switch and a grounding wire to the lower left corner of the electrical panel.
limit switches
Be certain to the labeled voltage and phase of the operator matches the
available supply. Also be certain to oversize the branch circuit wires to allow for voltage drop,
especially for single-phase machines. See the wire size schedules in the appendix. Machines to
operate on high voltages (above 120 VAC) do not need a neutral wire.
g) Verify that the primary tap of the control transformer is connected to match the supplied voltage.
It is especially important to distinguish between 208 and 230 volt supplies. The various voltage
taps are identified by a label on the transformer.
6) Test and Adjust the Operator (See Smart Touch Setup First)
a) Test basic functions of the operator first, before connecting any external control wiring. If your
operator is equipped with vehicle detectors, be certain that they are connected to a loop or
unplugged so that they do not cause interference with the function of the machine. If the motor
turns, but nothing moves, reverse two poles of a three phase power source. Also check that the
by-pass valve is closed. Push in the round black knob that is located on the right side of the pump
manifold. Also be certain that the hose quick connectors are firmly engaged.
b) After testing the basic functions, add accessories and external control wiring. Fully test the
operator functions again.
