IMPORTANT INFORMATION
WHEN INSTALLING YOUR BYAN OPERATOR, ALWAYS INSTALL THE OPERATOR WITH THE GATE
LEAF IN THE CLOSED POSITION.
If your gate has an INWARD swing:
Locate the rear mounting bracket on the gate post. After making sure of your “A” and “B”
dimensions, connect the operator to the power supply and extend the piston fully, making sure
to use the power supply. Attach the swivel joint and locknut to the piston; SCREW IT IN HALF
OF THE WAY ONLY.
With the gate leaf in the CLOSED position, place the operator on the rear mounting bracket and
in this manner, locate the position of the front mounting bracket. The “C” dimension for the
front mounting bracket should be taking from the FACE of the gate leaf.
If your gate has an OUTWARD swing:
Follow the procedure above, making sure that the piston is in the fully RETRACTED position.
THE MODEL 600 OPERATORS USE A FRONT MOUNTING BRACKET WITH A SHOULDER OF
APPROXIMATELY 5/8-INCH. THIS MEANS THAT WHEN YOU LOCATE THIS BRACKET ON THE
GATE LEAF, YOU MUST WELD IT APPROXIMATELY 5/8-INCH LOWER THAN THE REAR MOUNTING
BRACKET ON THE GATE POST.
THE OPERATING PRESSURES ON YOUR OPERATOR HAVE BEEN FACTORY-SET. IF YOU
NEED TO ALTER THESE PRESSURES, PLEASE CONTACT BYAN SYSTEMS AT [phone]
OR [phone] BEFORE MAKING ANY CHANGES.

This patented new concept in linear actuator design eliminates the need for physical stops. The valve design cushions the
last half inch (or approximately the last 5° to 10°) of piston travel, allowing the piston to reach the end of the stroke in
both directions and prevents internal damage.
Operator body fabricated in anodized aluminum
Front and rear flanges are cast aluminum
All internal components are cast and machined
Internal components bathed in oil so virtually no maintenance is required.

MODEL 600 SERIES OPERATOR | Rev. 2019.7.1
BEFORE INSTALLATION
1. Verify the gate post is plum and gate leaf swings freely.
2. Perform any required maintenance before continuing.
3. Verify the commercial power circuit breakers are isolated and rated for the specific load. Visually ensure
the circuit breakers are in the OFF position and mark the breaker “used”.
4. If any pre-construction wiring has been installed, visually inspect and confirm proper sizing and compliance
to code.
5. Automatic vehicular gates are NOT approved for pedestrian traffic; however, they can create hazards to
unsuspecting pedestrians and domestic animals. Any gate, constructed with reachable pinch points, or that
has a surface area that allows arms or legs to pass through it, is a potential hazard. Recommend and provide
safety guards against these hazards.
6. Remove the “End User Safety Advisory Handout” from this manual. Request the end user review the
material and sign it. Collect the signed handout when the installation / job is completed.
7. Remove all pull ropes and remove, or make inoperative, all locks (unless mechanically and/or electrically
interlocked to the power unit) connected to the door before installing the operator.
DURING INSTALLATION
**WARNING**
PLACARDS SHOULD BE MOUNTED IN A VISIBLE
LOCATION ON BOTH SIDES OF THE GATE
1. Locate the electronic controls far enough from the gate so that the end user can observe, but not touch,
the gate while operating the controls.
2. When connecting the wiring from the commercial power source to the control panel, make sure you have
provided a proper earth ground. If using a metal enclosure, connect the ground to the enclosure before
connecting to the gate operators. DO NOT connect the ground directly to the microprocessor control
board.
3. Observe all wiring requirements established by the National Electrical Code and/or the authority having
jurisdiction.
4. Mount the linear actuator as close to the center of the gate leaf as possible. This will help balance the
whipping motion of the gate when the operator reaches the end of the piston stroke.
5. Isolate the linear actuator when welding to prevent any current from passing through the operator and
damaging the motor or other components.

-10-
MODEL 600 SERIES OPERATOR | Rev. 2019.7.1
INSTALLING THE OPERATOR
This linear actuator must be mounted so the piston FULLY EXTENDS AND FULLY RETRACTS. When fully
retracted, there should be 3/8-inch of the piston left out of the front of the casing.
This linear actuator has an offset between the front and rear mounting brackets. The front bracket is
approximately 5/8-inch lower than the rear bracket. Review the Bracket Alignment details for the offset
dimension. The front bracket has the taller shoulder.
1. Scribe a line from the horizontal support (or desired height for the operator on the gate leaf) onto the gate
post.
2. Measure for the offset described above and scribe another line.
3. Cut the rear mounting bracket in accordance with the dimensions specified on the Mounting Geometry
detail.
4. Weld the rear mounting bracket to the gate post.
5. Determine the “C” dimension and cut the front mounting bracket to the proper length.
6. Extend the piston to the fully extended position for inward swing gates. This can be achieved by
temporarily connecting the control panel to the operator and using the motor to extend the piston,
producing 9-7/8” of piston.
7. Screw the I-bolt into the end of the piston ½ of the length of the threads. Attach the front bracket to the
operator.
8. Attach the operator to the rear mounting bracket.
9. With the gate in the full CLOSED position, level the operator and scribe the location for the front mounting
bracket.
10. Remove the front mounting bracket from the front of the gate operator and weld it to the gate leaf at the
scribed location.
11. Attach the operator to the front mounting bracket.
12. Attach an 18/4 stranded S.O. cord approved for outdoor use as per the strain relief assembly to the
operator per the electrical connection
NOTE: It is helpful to install a single gang, weather-proof Bell box on the gate post across from the
operator. Next, the wire from the control box can be pulled to this point and connected to
the S.O. cord inside the Bell box.
THIS SYSTEM SHOULD ONLY BE INSTALLED AND/OR MODIFIED BY
QUALIFIED TECHNICAL PERSONNEL

INSTALLATION COMPLETION
WARNING
TO REDUCE THE RISK OF SEVERE INJURY OR DEATH,
READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS
1. Install placards and safety equipment and test.
2. Remove all debris and obstructions from the travel path of the gate leaf(s).
3. Turn on and label the commercial power circuit breaker and remove the “used” tag you installed at the
beginning of the project.
4. Using the manual bypass, position the gate leaf at 45 degrees. Press the test button on the G2M+ Control
Board. The first signal will always be to OPEN. If the operator runs to the CLOSED position, turn off the
commercial power and reverse the motor connections on Pins 1 and 3.
5. Operate the actuator several times until you can detect a rise in the hydraulic fluid temperature. This can be
determined by placing your hand on the top of the operator at the rear.
6. Purge and adjust the operator as described in “Purging and Adjustments” section.
7. Instruct the end user how to manually release the gate in the event of a power failure.
8. Instruct the end user how to properly operate the gate automation and safety features thereof.
9. Collect the signed “End User Safety Handout”. By signing, the end user acknowledges their understanding of
their responsibilities in owning, operating and maintaining a vehicular automatic gate operating system.

MODEL 600 SERIES OPERATOR | Rev. 2019.7.1
PURGING THE OPERATOR
THIS STEP IS NOT REQUIRED UNLESS THE OPERATOR IS RUNNING ERRATICALLY
Occasionally during the shipping process, the 600 Series Operator may be turned upside down. This may require
the valve system to be purged after you have completed the installation. It is possible to determine if this is
necessary by whether or not the operator runs in a smooth manner. If it does not (if it jerks or runs unevenly),
use the Allen wrench provided under the locking cap, turn the manual bypass valve COUNTER-CLOCKWISE one-
half turn. Slowly swing the operator full open and closed for six to seven complete cycles. Then slowly remove
the fill cap on the rear flange of the operator to expel the air. Replace the fill cap.
Tighten the bypass valve with the Allen wrench and signal the operator to run. While the motor is running, open
and close the bypass valve, pausing between OPEN and CLOSE. Do this ten to twelve times. When finished,
remove the fill cap to expel the air from the operator. Replace the oil filler cap screw and tighten until snug.
DO NOT OVER TIGHTEN.
ADJUSTING THE OPERATOR
The pressures on the operator are preset at Byan Systems prior to shipment. If the pressures should need to be
adjusted, whether higher or lower, you MUST adjust both pressure directions the same amount of turns (i.e. ¼
turn or ½ turn, etc.)
The Pressure Adjustment screws are found under the locking cap on the top of the operator. Looking from the
rear to the front of the operator, the left valve adjusts retracting pressure and the right valve adjusts extending
pressure. Turning these valves clockwise INCREASES pressure, and turning them counter-clockwise
DECREASES pressure.
With the motor running, DECREASE the pressures equally until the operator stops moving in both directions.
Begin increasing pressure on both valves with the motor running. Adjust the pressure to where it is necessary
to physically stop the gate. At this point, either increase the retracting pressure OR decrease the extending
pressure ½ to ¾ of a turn. The retracting pressure MUST be higher than the extending pressure.
HYDRAULIC FLUID
Byan Systems Operators use Fuchs Aceite Multi-Temp Hydraulic Fluid. This fluid has a relatively low viscosity
enabling it to start flowing more quickly in colder weather. Once the fluid reaches operating temperature, it
has a steady flow meaning no rush of thin fluid to cause poor hydraulic performance, or worse yet, excessive
pump wear, failure and expensive operational downtime.
Fuchs fluids minimize the effect temperature has on viscosity and resists the shearing action of high speed
pumps by maintaining their stable viscosity longer.
There is a zinc type additive in the fluid to help impede wear and premature replacement. It helps prevent
corrosion to metals and is designed to be compatible with the hoses, seals and other elastomer products.
Fuchs Aceite Multi-Temp readily separates air and water to prevent foaming, keeping the hydraulic fluid fit and
dielectric strength high.

-13-
MODEL 600 SERIES OPERATOR | Rev. 2019.7.1
WHERE TO BUY FUCHS ACEITE MULTI-TEMP HYDRAULIC FLUID
At your nearest Fuchs Oil Distributor, Byan Systems Distributor, or at Byan Systems Warehouse.
FLUID AND YOUR OPERATOR
The proper level can be observed through the oil filler tube, located on the top of the rear flange of the operator,
with the piston in the retraction position. The fluid should be visible at the bottom of the tube, level with the
curved section of the tube. The 600 Series Operator has a pressured chamber so DO NOT OVERFILL. The pump
will intermittently fail to draw fluid and will fail to run in one direction or the other.
ADJUSTABLE FLOW CONTROL
The operator has adjustable flow control to allow for speed adjustment. This helps with heavy gates and wind
loads. There is a built-in slow down on the last ¾” of the piston’s travel which eliminates the need for the
installation of physical stops.
MANUAL BYPASS
The manual bypass valve is for the ability to release the operator in the event of a power failure or malfunction.
It is located under the keyed cap on top of the operator. A Metric Allen wrench is provided and is located in the
cap to release the bypass valve. Turn the valve counter-clockwise until the operator releases. When tightening
the bypass valve, it must be tight in order to prevent fluid or pressure from escaping backing into the chamber.
PLACARDS AND SAFETY EQUIPMENT
The placards should be installed (one on each side of the gate) so that they are visible to anyone that approaches
the gate. The safety equipment should be tested before leaving the gate site.

-14-
MODEL 600 SERIES OPERATOR | Rev. 2019.7.1
PRESSURE AND FLOW CONTROL
When mounting the operator to your gate, always make sure that the side with the lock cap (or
the Green and Red Pressure Adjustment Screws) is facing upward. Mounting your operator in
an upside-down position will result in it failing to run properly.
⧫Pressure and flow control
are factory set for best
performance.
⧫If pressure adjustment in
required, the Extend and
Retract pressures must be
adjusted equally. Equal
adjustment to controls is
required to increase and
decrease pressure.
⧫Flow control is set by the
factory for maximum speed.
⧫To reduce the operator’s
speed, turn the flow control
screw clockwise up to one-
half turn.
⧫DO NOT TURN THE FLOW
CONTROL ADJUSTMENT
SCREW COUNTER-
CLOCKWISE FROM THE
FACTORY SETTING.
⧫The manual by-pass
screw is set at the factory
and can be released with
the allen wrench provided.
Do not turn more than one
turn counter-clockwise to
move the gate manually.

RECOMMENDED WIRE SIZES
Voltage drop becomes important when the length of a run of wire or cable becomes very long. Usually this is not a problem
in circuits within a house, but may become an issue when running wire to your gate’s control box.
Excessive voltage drop can cause loss of efficiency in operation of your gate system. It not only can even result in
shortening the life of your electronic equipment.
To avoid excessive voltage drop, select wire size that will minimize voltage drop, you will need to know the length of the
wire run and the amp load or current that will be on the circuit. To determine amps, add up the wattage of all electrical
devices that will be on the circuit and divide the total by the voltage of the circuit (either 110 volts or 220 volts).

NOTE: These wire sizes are only general recommendations. Federal, state and local codes ALWAYS take
precedence. Consult the National Electrical Code or local authority having jurisdiction if you have
wiring concerns.
*The tables above apply to the single phase systems, in steel conduit, at a conductor operating temperature
of 167°F (75°C). It assumes a power factor of one. The table may be used for systems using non-steel
conduit, but actual results for these conditions may result in a greater voltage drop.
WARNING! Installation of electrical wire can be hazardous, if done improperly and can result in personal injury or property
damage. For safe wiring practices, consult the National Electrical Code and your local building inspector.
