Read the following before beginning to install OSCO swing
gate operators:
1. Readtheorange “Safety Instructions”brochureenclosed
with the packet of information. If you do not have one,
pleasecallOSCOat1-800-333-1717torequestone. Read
andfollowallinstructions.
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
neartheoperatorso that primarypowercanbe turned off
whennecessary.
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
operatethegate.
6. You must install all required safety equipment.

PRE-INSTALLATION
INFORMATION
Before unpacking, inspect the carton for exterior damage. If
youfinddamage,advisethedeliverycarrierofapotentialclaim.
Inspect your package carefully. You can check your
accessory box parts with the enclosed packing slip for your
convenience.Claimsfor shortageswillbehonored foronly30
days from the date of shipment.
Before installing the operator, read this manual completely
toensureallrequirementsforproper installation are present.
Verify that the voltage to be used matches the voltage of the
operator.
SAFETYINFORMATION
ANDWARNINGS
IMPORTANT!!
Beforeinstallingthegateoperator,make surethegate’sswing
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
resistanceanddrag.
The following contact or non-contact obstruction
detection devices have been approved for use
with OSCO slide gate operators as part of a UL325
compliant installation:

Distance (ft.)
Wire
Gauge
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 opera-
tor to the power source. DO NOT EXCEED THE MAXIMUM DIS-
TANCE. 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 appli-
cation 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 sup-
plied) may be needed for the operator power connection.
4. All control devices are now 24VDC, which can be run considerable
distances. 24VAC is available for other devices, such as loop detec-
tors and photo eyes.
5. Wire run calculations are based on the National Electrical Code, Ar-
ticle 430 and have been carefully determined based on motor inrush,
brake solenoids, and operator requirements.
WIRINGSPECIFICATIONS
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 de-
crease 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
andslaveoperators.You must use Belden 8760TwistedPair 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.

STRINGMETHODFORNONSTANDARDINSTALLATIONOFSWINGGATEOPERATORS
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. Positiontheoperator parallel tothegate.The distancefromtheoperator
output shaft to the gate plate pivot point is shown at right. The operator
shouldbepositionedthesame distance from the gatehingeasthegate
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
writeit down.
3. Openthegate.
4. Pick up the string, while it is still attached at both ends, and pull it taut
againwhilepositioningit directly overthecenterofthe operator shaft, at
Point“B,”andwork yourwaybackalong the stringuntilyoureach 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 1measurement.

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 dimen-
sions,whichwouldalso include otherattachmenthardware,such as gate
arm clamps.
It is also possible that both open and closed limit switches may be acti-
vatedateitherendofgatetravel due to the total gate travelrequired,and
theshape of the limit switches and cams. This problem can becorrected
by carefully bending the limit switch arm slightly and readjusting its cam.

ELECTRICALCONNECTIONANDADJUSTMENTS
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 wiringspecifications on page 4.Awiringconnectionsprintcanbefoundontheinsidecoveroftheoperator.

LIMITCAMADJUSTMENTS
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
installedon.The limitswitchesareactivated by aseriesof rotating limitcamswhichare attachedtothedrive shaft.Theoperator

With the gate connected tothe gate operator in a mid-travel position,the power disconnect switch turned OFF,andthetorque
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.
Afterfinishingtheinitiallimitcamadjustments,repositionthe 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

Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically,
providednoopen, reversingorobstructionsignals arepresentfrom thefully-openposition.This timerisadjustablefrom 0to124
seconds. This feature is turned on or off using dip switch #1.
Maximum Run Timer Adjustment: This270-degreeadjustablepotentiometerwillsignal 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
featurefordetectionofobstructionswhile running in the open direction.

#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.

You must follow all required safety precautions and instructions at all times. Review the safety brochure
included with the operator. If any pages are missing or unreadable, contact OSCO at 1-800-333-1717 to request
additional copies.
Never connect a button station within reach of the gate or on the side of the gate operator.
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!

2 & 4 STOP Stops the operator. If no stop button is used, a jumper is required across 2&4.
4 & 6 REVERSE Thisfunctionwillcause a reversal when the gate is traveling closed and will travel
back to the fully open position. Loop detectors are often wired for reverse.
4 & 50 OPEN This function works only while the operator is opening. Any signal to this function
will cause the gate to stop, reverse a short distance, and then stop again. At this
time the auto close timer is disabled, and a renewed input will be required to start
the gate again. Should the gate be restarted and the signal occur again prior to

CURRENTSENSINGADJUSTMENTS
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
movingundernormal conditions withoutinterruption.
Priortoadjustingthe operator current sensingfunctions,makesurethe gate moves freelyinbothdirections.A badly aligned or
poorlymaintainedgatemaycausefalse triggeringofthecurrent sensor.Refer to page10when followingtheinstructionsbelow.
Afactory adjustment tool has been supplied to make these adjustments easier.This tool has been taped to the control box for
yourconvenience. CLOSEDIRECTIONCURRENTSENSEADJUSTMENT
When the gate operator leaves the factory, it has been preset for a relatively light gate function and will require additional
adjustment.Beginby starting the gate going closed. If the operator stops and reverses, turn the close direction potentiometer
(seepage10) one turn higher,presstheSTOP button, and tryagain.Repeatthisprocessuntilthegate no longer causes false
trippingofthecurrent sensor.Notethat each timethegateoperatorreverses, the STOP buttonmust be pressed.Next,turnthe
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 VoltAC and 24 Volt DC
operators,andby3/4 of a turn higherforall230VoltACoperators.Additionalfineadjustmentby1/4 turns may benecessaryto

OPENDIRECTIONCURRENTSENSEADJUSTMENT
Repeatthesameprocess with the opendirectionpotentiometerwhilerunning the gate intheopendirection.Oncethis is done,
run the gate through several complete cycles and make sure the gate does not false trip in either direction.

installed! MASTER/SLAVECONNECTION
Athree-wire shielded conductor cable is required to connect master and slave operators.You must use Belden 8760 Twisted
Pair Shielded Cable(or equivalent) only –OSCOpartnumber2500-1982, per foot).Seepage10 for details ofthisconnection,
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.
Multi-turn Potentiometer
Remember it is important not to set the adjustment
too high! Doing so will defeat the purpose of the cur-
rent sensing as an obstruction detecting feature.

ONBOARDL.E.D.INDICATORDESCRIPTIONS
Control Board L.E.D. Indicators:
OPEN This indicator is lit when an open signal is present. This signal can come from such devices as button
stations, radio receivers, keypads and telephone entry systems.
CLOSE This indicator is lit when a closed signal is present. This signal typically comes from three-button stations.
STOP This indicator is lit when there is a break in the stop circuit. Make sure there is a stop button wired in and
workingproperly.
SINGLE This indicator is lit when a signal from a single-button station or radio receiver is present.
CLOSEOBST This indicator islitwhenaclose obstruction signalispresent. Thissignalcancome from edgesandphoto
eyes which have been wired to the close obstruction inputs.
OPENOBST This indicator is lit when an open obstruction signal is present. This signal can come from edges and
photoeyeswhichhavebeenwiredtotheopenobstruction inputs.
SAFETYLOOP This indicator is lit when a reversing signal is present. This signal is generated by a loop detector wired to
the safety loop terminals.

IMPORTANTNOTESFOR
INSTALLATIONOFMASTER/SLAVEAPPLICATIONS
When setting up Master/Slave gate operators, it is best to make adjustments and run each operator individually. To do this,
simply:
a. SetDipSwitch#4 to proper handofoperation(right-handor left-hand)
b. Set Dip Switch #8 as Master (off)
Runeachoperatormakingcurrentsensingadjustmentsasnecessary, as indicated on the Control BoardAdjustmentspageof
this installation guide. When both operators have been adjusted, turn power off, then turn on Dip Switch #8 in the operator
chosenastheSlave.

SURGEPROTECTORINSTRUCTIONS
The optional surge protector should be connected
to any inputs that have an accessory connected to
it. This includes the 3-button station, so it must be
connected to 1, 2A and 3 in all cases. The green
wire connected to ground, which is electrically the
same as terminal 4. The red wires connect to
terminals 2A and 24VDC+. This will cause the
2 amp fuse to blow if this section of the module
becomes shorted. With any of the other inputs
connectedtothesurgeprotector,iftheirprotection
linebecomesshorted due toasurgeover therating
of the module, the corresponding LED on the main
board will remain lit, causing a constant signal to
the controller. If this is found, please replace the
entiresurge protector with a new unit.
Do not simply unhook the shorted wire, as this
removestheprotection fromthecircuit thatwas
saved by the protector in the first place!
