GATE OPERATOR
CLASSIFICATIONS
All gate operators can be divided into one of four different
classifications, depending on their design and usage.
Class I Residential Vehicular Gate Operator
A vehicular gate operator intended for use in a home of one to
four single family dwellings, or garage or parking area associated with these dwellings.
Class II Commercial / General Access Vehicular Gate
Operator
A vehicular gate operator intended for use in a commercial
location or building such as a multifamily housing unit of five
or more single family units, hotel, retail store or other building
servicing the general public.
Class III Industrial / Limited Access Vehicular Gate
Operator
A vehicular gate operator intended for use in an industrial
location or building such as a factory or loading dock area or
other location not intended to service the general public.
Class IV Restricted Access Vehicular Gate Operator
A vehicular gate operator intended for use in a guarded industrial location or building such as an airport security area or
other restricted access locations not servicing the general
public, in which unauthorized access is prevented via supervision by security personnel.
IMPORTANT!!
Before installing the gate operator, make sure the gate’s swing
is free and level throughout the entire swing path. If the gate
does not seem to operate properly, it may affect the operator
performance or greatly shorten the life of the unit. The gate
should be designed so that airflow is ample to prevent wind
resistance and drag.
SAFETY INFORMATION
AND WARNINGS
Read the following before beginning to install OSCO swing
gate operators:
1. Read the orange “Safety Instructions” brochure enclosed
with the packet of information. If you do not have one,
please call OSCO at 1-800-333-1717 to request one. Read
and follow all instructions.
2. All electrical connections to the power supply must be
made by a licensed electrician and must observe all
national and local electrical codes.
3. A separate power-disconnect switch should be located
near the operator so that primary power can be turned off
when necessary.
4. Install the enclosed warning signs on both sides of the
gate. Each sign must be plainly visible from the side of
the gate on which they are mounted.
5. Never reach between, through or around the fence to
operate the gate.
6. You must install all required safety equipment.
PRE-INSTALLATION

WIRING SPECIFICATIONS
1. Select from the chart at the bottom of this page corresponding to the model, voltage and horsepower rating of
your operator.
2. The distance shown on the chart is measured in feet from
the operator to the power source. DO NOT EXCEED THE
MAXIMUM DISTANCE. These calculations have been
based on standard 115V and 230V supplies with a 10%
drop allowable. If your supply is under the standard rating,
the runs listed may be longer than what your application
will handle, and you should not run wire too near the upper end of the chart for the gauge of wire you are using.
3. When large-gauge wire is used, a separate junction box
(not supplied) may be needed for the operator power connection.
4. All control devices are now 24VDC, which can be run considerable distances.
5. Wire run calculations are based on the National Electrical
Code, Article 430 and have been carefully determined
based on motor inrush, brake solenoids, and operator requirements.

6. Connect power in accordance with local codes. The green
ground wire must be properly connected.
7. Wire insulation must be suitable to the application.
8. Control wiring must be run in a separate conduit from power
wiring. Running them together may cause interference and
faulty signals in some accessories.
9. Electrical outlets are supplied in all 115VAC models for
convenience with occasional use or low power consumption devices only. If you choose to run dedicated equipment from these devices, it will decrease the distance for
maximum run and the charts will no longer be accurate.
10. A three-wire shielded conductor cable is required to connect master and slave operators. You must use Belden
8760 Twisted Pair Shielded Cable (or equivalent) only –
OSCO part number 2500-1982, per foot). See page 10 for
details of this connection, as well as dip switch selection.
Note: The SHIELD wire should be connected in both
the master and slave operators.

PAD MOUNTING INSTRUCTIONS
NOTE: Maximum gate opening angle is
approximately 95 degrees, depending
on gate width. If larger opening angle
is required, non-standard positioning
of the operator and modified articulating arms will be required. Contact the
factory for pricing and availability.
PAD MOUNTING INSTRUCTIONS
Recommended pad size is 24”x20”x18” deep minimum.
Pad depth should be set according to local codes and at
least as deep as frost line. If soil conditions may cause
operator and pad to shift during operation, anti-rotation
legs may be required. Use two 6” diameter, 10” deep
legs to counteract this problem as shown. 5/8” J-bolts
may be set into the concrete before it sets following the
dimensions shown, or drilled after the concrete sets.
A large, 2 inch diameter hole has been supplied for conduit placement. Use of flexible conduit will make it easier
to line up with this opening.
Assemble the arm components as shown on page 7.

STRING METHOD FOR NONSTANDARD INSTALLATION OF SWING GATE OPERATORS
Step A: Position the Operator
1. Connect the gate plate assembly onto the gate at the recommended
location for a standard installation (Dimension “W”).
2. Open the gate to its fully-open position.
3. Position the operator parallel to the gate. The distance from the operator
output shaft to the gate plate pivot point is shown at right. The operator
should be positioned the same distance from the gate hinge as the gate
plate has been; ie: the “W” dimension.
Step B: Measure the Crank Extension and Link Center to Center
Distances
1. Close the gate.
2. Using a piece of tape, attach a string to the top of the operator output
shaft, at its center. Holding the string taut and using another piece of
tape, hold the other end of the string across the hole in the gate plate.
This distance is Dimension 1. Carefully measure this dimension and
write it down.
3. Open the gate.
4. Pick up the string, while it is still attached at both ends, and pull it taut
again while positioning it directly over the center of the operator shaft, at
Point “B,” and work your way back along the string until you reach Point
“C.”
5. While holding the string taut, measure the distance from Point “B” to
Point “C.” This is the required center to center distance for the crank
extension.
6. Measure the distance from Point “A” to Point “C.” This is the required
center to center distance for the link section.
7. When added together, the distances from Point “A” to Point “B” and
Point “B” to Point “C” should equal the Dimension 1 measurement.
DOOR MUST
FACE AWAY
FROM
FENCELINE
These measurements will be needed when placing an order for special
length crank extensions and links. Also note that the measurements you
have just calculated are center to center only, and are not overall dimensions, which would also include other attachment hardware, such as gate
arm clamps.
It is also possible that both open and closed limit switches may be activated at either end of gate travel due to the total gate travel required, and
the shape of the limit switches and cams. This problem can be corrected
by carefully bending the limit switch arm slightly and readjusting its cam.
PLEASE NOTE: Your operator may look different when installed.
The drawings on this page are for general reference only.

WELDED STYLE GATE ARM INSTALLATION INSTRUCTIONS
The welded style gate arm has been pre-assembled at
the factory in right-hand configuration (the back of the
overtravel stop faces toward the drive when the gate is
fully closed and the arm is installed). For a left-hand
operator, rotate the upper portion of the arm as shown
above to convert the arm into a left-hand orientation.
The gate plate supplied with the arm assembly can be
welded to the gate as shown above. Holes have been
provided for securing the gate plate to an aluminum gate.
If the operator is mounted using the standard dimensions specified in the installation manual, the dimensions above can be used to adjust and set the arm. If
non-standard mounting is required, utilize the string
method from the operator manual to determine the A to
C and B to C lengths required.
Once these lengths have been determined, use clamps
to temporarily attach the solid bars to their sections of
rectangular tubing. If clamps are unavailable, you may
also tack weld the parts in place. It is recommended
that you check the arm for proper action and full gate
travel before fully welding the parts together. Apply
Krylon metallic gold spray paint or equivalent to touch
up weldments when finished.
Good harmonics are necessary to minimize wear and
tear on the operator. The illustration at right shows an
example of an improperly adjusted arm and one that
has been properly installed.
- 7 -
The hex cap screws in the side of the crank assembly
are shipped loose for placement on the operator drive
shaft. Once in place, tighten these cap screws in place
by applying 75 ft•lbs of torque. If it becomes necessary
to remove the crank, you can do so by loosening these
bolts. The arm can also be disconnected for manual
operation of the gate by removing the disconnect pin.

SWR • SWC • SWD OPERATOR INSTALLATION GUIDE
VENT PLUG INSTALLATION
Gear reducers used in OSCO gate operators will have solid plugs installed prior to shipment in order to keep the oil inside from
spilling out during shipping. A vent plug has been provided to replace this plug during installation. This plug will look similar to the
ones shown below. Some models may have a vent plug with a breather pin. This pin should be removed after installing the
operator.
OR
TORQUE LIMITER ADJUSTMENT
This operator may be supplied with an optional torque limiter.
Before adjusting the torque limiter, make sure the gate is in
good working condition. One person should be able to move
the gate by hand. Be certain the gate moves freely and without
binding throughout its travel. Torque limiters are set light at the
factory. They must be adjusted during installation, preferably
after limit cams have been manually set (see page 9). Adjust
the torque limiter tight enough to keep it from slipping during
normal operation.
To adjust the torque limiter in models SWR and SWD:
1. Bend the locking tabs away from the adjustment nut.
2. To increase the output, turn the adustment nut clockwise
one flat, or 1/6 turn, at a time until desired output is obtained.
To reduce the output, turn the adjustment nut counterclockwise one flat, or 1/6 turn, at a time until desired output is
obtained.
3. Bend the lockng tabs up to lock the adjustment nut in place.

ELECTRICAL CONNECTION AND ADJUSTMENTS
Power supply must be of correct voltage and phase.
Always disconnect power from operator before servicing.
Keep clear of gate during operation.
All OSCO gate operators are supplied with a power disconnect switch to turn on and off the power supply available to the
operator. Incoming power should be brought into the operator and connected to the labeled pigtails in the disconnect box,
following wiring specifications on page 4. A wiring connections print can be found on the inside cover of the operator.
Proper thermal protection is supplied with the operator. The motor contains a thermal overload protector to protect from overheating the motor due to overload or high-frequency operation. This overload will reset automatically after the motor cools down.
LIMIT CAM ADJUSTMENTS
The limit cams are not preset at the factory and must be adjusted for the length and opening angle of the gate the operator is
installed on. The limit switches are activated by a series of rotating limit cams which are attached to the drive shaft. The operator
has also been preset in the right hand operation mode. If the installation requires left hand operation a dip switch must be flipped
(see page 10).
With the gate connected to the gate operator in a mid-travel position, the power disconnect switch turned OFF, and the torque
limiter set loose enough to slip freely, manually move the gate to its fully open position.
Once the gate is in the fully open position, adjust the limit cam for open direction. Set the LSO-1 limit cam so that it has just
triggered its switch.
Once the open limit cam is set, repeat the above process for the close direction, LSC-1.
After finishing the initial limit cam adjustments, reposition the gate to approximately the center of travel. At this time, adjust the
torque limiter as explained on page 8. Turn the power disconnect switch ON, stand clear of any moving parts and press the
OPEN button. Observe the gate as it runs through a complete cycle in both directions, and adjust your limits again if necessary.If
the operator stops during travel, you may need to adjust the open or close current sensor adjustment or the maximum run timer
(see page 12).

CONTROL BOX ACCESS AND REMOVAL
The control box in models SWR, SWC and SWD is hinged for flip-down access and can be removed without taking off the
operator cover. Start by pulling down the plunger located on the left side of the control box. While holding the plunger down, slide
the control box to the right until the hinges have come apart. Once freed, you can turn the control box slightly and remove it from
the operator. Be careful not to pull on the cables that connect to the control box.
Under most circumstances you will not need to remove the control box. By pulling the plunger and swinging the control box
down, you can gain access for installation and troubleshooting.

Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically,
provided no open, reversing or obstruction signals are present from the fully-open position. This timer is adjustable from 0 to 124
seconds. This feature is turned on or off using dip switch #1.
Maximum Run Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to stop running once it
counts down, unless a limit switch is reached or an input is received first. Each time the motor starts, this timer will begin
counting. This timer is adjustable from 15 to 100 seconds. If the timer expires, the unit locks out and the emergency alarm
sounds.
Open Direction Current Sense Adjustment: This multiturn potentiometer is used to calibrate the built-in current sensing
feature for detection of obstructions while running in the open direction.
Close Direction Current Sense Adjustment: This multiturn potentiometer is used to calibrate the built in current sensing
feature for detection of obstructions while running in the closed direction.
Master/Slave Connection Block: This terminal block is used in conjunction with two operators to configure two gates to open
and close together.
Dip Switches:
#1 This switch turns the auto close timer off/on.
#2 This switch is used in conjunction with alarms and flashing lights that may be added to the operator. When the switch is
in the ON position, these devices will start approximately two seconds prior to the operator starting. In the OFF position,
the devices will only work while the operator is running.
#3 This switch is used in conjunction with single-button controls and radio receivers. In the ON position, successive inputs
will cause signals in the order of OPEN-STOP-CLOSE-STOP. In the OFF position, inputs will cause an OPEN signal
unless the gate is fully open, in which case it will signal CLOSE.
#4 This switch determines right-hand vs. left-hand behavior. When looking from inside the protected area toward the gate, the
side of the drive the operator is on determines its hand of operation. In the OFF position, the operator is set for right-hand.
#5 When turned ON, this switch will allow a one-second delay for solenoid locks to unlock before the motor starts.
#6 In the ON position, the reverse delay is three seconds. In DC operators only, this also disables the inherent DC brake
(provided the R2 brake resistor is cut, see picture above). In the OFF position, the reverse delay is 1 1/2 seconds and the
DC inherent brake is enabled.
#7 Not used at this time.
#8 This switch is used to set Master/Slave configuration. Operators which are stand-alone or master units should be set to
OFF, while only slave units should have this switch set to ON.

This is typically used with a loop and loop detector to keep a large swing gate
open while vehicular traffic is passing through.
Depending on dip switch #2, these devices will either begin three seconds before
the operator starts, or only while the motor is running. (See page 10 for details.)
Do not adjust the circuit board current sensing feature too high. It should be adjusted high enough to keep the
gate from falsely triggering the sensing, but no higher than necessary for the gate to operate. Do not defeat the
purpose of this function!

SWR • SWC • SWD OPERATOR INSTALLATION GUIDE
CURRENT SENSING ADJUSTMENTS
Because gates vary in construction and may have different force requirements in the open and close directions to move, the
OSCO control board has separate Multi-turn potentiometers for adjusting in both directions independently. The adjustment
should be set light enough to maintain minimal force (40 lbs.) should an obstruction occur, but high enough to keep the gate
moving under normal conditions without interruption.
Prior to adjusting the operator current sensing functions, make sure the gate moves freely in both directions. A badly aligned or
poorly maintained gate may cause false triggering of the current sensor. Refer to page 10 when following the instructions below.
A factory adjustment tool has been supplied to make these adjustments easier. This tool has been taped to the control box for
your convenience.
CLOSE DIRECTION CURRENT SENSE ADJUSTMENT
When the gate operator leaves the factory, it has been preset for a relatively light gate function and will require additional
adjustment. Begin by starting the gate going closed. If the operator stops and reverses, turn the close direction potentiometer
(see page 10) one turn higher, press the STOP button, and try again. Repeat this process until the gate no longer causes false
tripping of the current sensor. Note that each time the gate operator reverses, the STOP button must be pressed. Next, turn the
close direction potentiometer lower slowly while the operator is running the gate closed until the gate operator stops and
reverses again. From this point, turn the close direction potentiometer higher by 1 1/2 turns for all 115 Volt AC and 24 Volt DC
operators, and by 3/4 of a turn higher for all 230 Volt AC operators. Additional fine adjustment by 1/4 turns may be necessary to
eliminate false triggering.
OPEN DIRECTION CURRENT SENSE ADJUSTMENT
Repeat the same process with the open direction potentiometer while running the gate in the open direction. Once this is done,
run the gate through several complete cycles and make sure the gate does not false trip in either direction.
Multi-turn Potentiometer
Remember it is important not to set the adjustment
too high! Doing so will defeat the purpose of the current sensing as an obstruction detecting feature.
MAXIMUM RUN TIMER ADJUSTMENT
This adjustable potentiometer sets the maximum length of time
the motor will run before shutting down. It should be configured
for the time it takes to run the gate fully open or closed, plus an
additional 15 seconds. See page 10 for details.
AUTO CLOSE TIMER ADJUSTMENT
This adjustable potentiometer sets the length of time which
elapses before the gate operator automatically closes the gate,
from the fully open position, provided no open, reversing, or obstruction signals are present. This feature can be turned on or off
via dip switch selection. See page 10 for details. Do not use the
auto close timer without an appropriate reversing device installed!
MASTER/SLAVE CONNECTION
A three-wire shielded conductor cable is required to connect master and slave operators. You must use Belden 8760 Twisted
Pair Shielded Cable (or equivalent) only – OSCO part number
2500-1982, per foot). See page 10 for details of this connection,
as well as dip switch selection. Note: The SHIELD wire should be
connected in both the master and slave operators. In addition,
you must run power to both the master and slave operators.
BATTERY BACK-UP
FOR DC MODELS ONLY
CHARGER BOARD CONFIGURATION
To set the voltage monitor, see the picture below. The RUN position will monitor the voltage of the battery only after AC voltage has
been interrupted. It will allow the operator to continue to function
until the batteries have dropped to 17 volts. When the batteries
have reached 17 volts, the operator will open and shut down until
AC power has been restored. In the OPEN ONLY position when
AC power has been interrupted the operator will open and shut
down until AC power is restored.
Note: If the charger board is set to open only, removing incoming
power will cause the operator to run to full open position. Turn off
power switch in operator before removing incoming power!
