GATE OPERATOR
CLASSIFICATIONS
All gate operators can be divided into one of four different
classifications, depending on their design and usage.
Class I: Residential
A vehicular gate operator (or system) intended for use in a
home of one to four single-family dwellings, or a garage or
parking area associated therewith.
Class II: Commercial or General Public Access
A vehicular gate operator (or system) intended for use in a
commercial location or building such as a multi-family housing unit (five or more single-family units), hotel, garage, retail store, or other building servicing the general public.
Class III: Industrial or Limited Access
A vehicular gate operator (or system) intended for use in an
industrial location or building such as a factory or loading
dock area or other locations not intended to service the general public.
Class IV: Restricted Access
A vehicular gate operator (or system) 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.
SAFETY INFORMATION
AND WARNINGS
Read the following before beginning to install OSCO slide
gate operators:
1. Read the yellow “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. Y ou must inst all all required safety equipment.
PRE-INSTALLATION INFORMATION
Before unpacking, inspect the carton for exterior damage. If
you find damage, advise the delivery carrier of a potential claim.
IMPORTANT!!
Before installing the gate operator, make sure the gate slides
free and level throughout the entire opening distance. 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 through the fabric is
ample to prevent wind resistance and drag.
Inspect your package carefully. For your convenience, you
can check your accessory box parts with the enclosed packing slip. Claims for shortages will be honored for only 30 days
from the date of shipment.
Before installing the operator, read this manual completely
to ensure all requirements for proper installation are present.
Verify that the volt age to be used matches the voltage of the
operator.
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:
Contact Edges:
Miller Models*: MG0-20, MGR-20, MGS-20, and ME-120

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 power supplies with a 10% allowable
voltage drop. If the available voltage is less than the standard rating, the wire lengths listed may be longer than
what your application will handle. If this is the case, you
should not allow your wire length to reach 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 wired
considerable distances.
5. Wire length calculations are based on the National Electrical Code, Article 430 and have been carefully determined based on motor inrush, brake solenoids, and operator requirements.
USE COPPER WIRE ONLY!
6. Connect power in accordance with local codes. All power
wiring should be done by a licensed electrician. 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 power dedicated equipment from these devices, it will decrease the distance for
maximum wire length 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 T wisted Pair Shielded Cable (or equivalent) only –
OSCO part number 2500-1982, per foot). See page 9 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 FOR MODELS
SLR, SLC & SLD
Before installing, make sure the gate rolls or slides freely ,
and that all exposed rollers are properly covered. The
gate must be covered with fabric with openings no larger
than 2 1/4” in size, to a minimum height of 48 inches
above ground level. On picket-style gates, if pickets are
spaced less than 2 1/4” apart, mesh is optional.
T o assemble the drive chain and gate bracket s, refer to
Page 6. Make sure that the chain sag does not exceed
recommended sizes and that the chain does not come
into contact with the moving parts of the gate or ground.

SLR • SLC • SLD OPERATOR INSTALLATION GUIDE
GATE BRACKET AND CHAIN ASSEMBLY INSTRUCTIONS
Numbered items in these
drawings are for instructional
reference only . For actual part
numbers, go to the parts lists
in the back of this booklet.
Assemble a gate bracket (1) to the front edge of the gate,
using two U-bolts (2), and mounting hardware (3). Before
tightening down completely , be sure the bracket is parallel
to the gate. Tighten the U-bolt hardware the rest of the way ,
then screw the square head bolts (4) into the threaded holes
in the gate plate until they bottom out against the gate.
These will help keep the bracket from twisting on the pipe.
Slide a threaded chain pin (5) through the bracket as shown,
with spring (6), flat washer (10), and two hex nuts (7). Attach one end of the drive chain (8) to the chain pin using
master link (9) and begin unrolling it toward the operator.
Remove the rain cover from the back of the slide gate operator. Carefully thread the drive chain under the first idler , over
the drive sprocket, and then under the last idler. Make sure
you feed most of the chain through the sprockets for attaching to the back end of the gate.
Assemble the other gate bracket on the rear edge of the
gate, using the same process as you did with the front gate
bracket. Once this is done, take the other chain pin, spring
and jam nuts and assemble with the end of drive chain and
the other master link.
At this point you should be able to adjust the chain tension
by tightening the jam nuts on each end. Approximately 1/4”
to 3/8” of slack per foot of drive chain is acceptable. Make
sure the chain does not drag on the ground, across the gate
rollers or the idler frame of the operator.
Additional mounting holes have been provided in the gate
bracket for installer convenience.

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
OPTIONAL TORQUE LIMITER
ADJUSTMENTS
Y our Model SLR, SLC or SLD may have an optional torque limiter.
Follow these instructions if you do.
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 and must be
adjusted during installation. Adjust the torque limiter tight enough to
keep it from slipping during normal operation.
T o adjust the torque limiter in models SLR, SLC and SLD:
1. Bend the locking tabs away from the adjustment nut.
2. To increase the output, turn the adjustment nut clockwise one
flat, or 1/6 turn, at a time until desired output is obtained.
T o 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 locking 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 automatically reset after the motor cools down.
LIMIT NUT ADJUSTMENTS
The limit nuts are not preset at the factory and must be adjusted for the length of the gate the operator is installed on. The limit
switches are activated by two threaded nylon rotary limit nuts which are attached to a threaded shaft and driven by chain and
sprockets from the main drive shaft. Remove the cardboard filler before attempting to adjust the limit nuts.
With the gate connected to the gate operator in a mid-travel position, and the power disconnect switch turned OFF, disconnect
the operator by using the manual disconnect lever. Instructions for the manual disconnect can be found in the individual operator
owner’s guides. Once the operator has been disconnected, manually move the gate by hand to within a foot of its fully open
position (the foot of distance is necessary to allow for coasting of the operator after the limit switch is tripped).
Once the gate is in this position, adjust the open limit nut until it activates the limit switch for open, LSO-1. Press down on the
detent plate and rotate the nut along the threaded shaft. Refer to the illustration below for additional details.
Once the open limit nut is set, repeat the above process for the close direction nut and the LSC-1 limit switch.
After finishing the initial limit nut adjustments, reposition the gate to approximately its center of travel. Re-engage the operator
and turn the power disconnect ON. Stand clear of any moving parts and press the OPEN button on the three-button station. If the
gate begins to close instead of open, press the STOP button immediately . Find the dip switch block on the main control board
and switch the hand of operation (dip switch #4, see page 9) and try to open the gate again. Observe the gate as it runs through
a complete cycle in both directions, and adjust your limits again if necessary . Fine levels of adjustment can also be achieved by
adjusting a few teeth on the nut at a time. If the gate stops in midtravel, the open or close current sensor adjustment or the
maximum run timer may need adjustment (see page 11).

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.

the gate again. Should the gate be restarted and the signal occur again prior to
reaching a limit, the gate will stop again, and this time will sound the emergency
alarm and lock out.
work in the closing direction.
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 9 for details.)
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!

SLR • SLC • SLD 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 (50-75 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 p age 9 when following the instructions below.
A factory adjustment tool has been supplied to make these adjustment s 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 9) one turn higher, press the ST OP 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 1 15 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 9 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 9 for details. Do not use
the auto close timer without an appropriate reversing device
installed!
BATTERY BACK-UP
FOR DC MODELS ONLY
CHARGER BOARD CONFIGURATION
T o set the volt age 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 ONL Y 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!
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 9 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.

SLR • SLC • SLD OPERATOR INSTALLATION GUIDE
IMPORTANT NOTES FOR INSTALLATION OF
MASTER/SLAVE APPLICATIONS
When setting up Master/Slave gate operators, it is best to make adjustments and run each operator individually. To do this,
simply:
a. Set Dip Switch #4 to proper hand of operation (right-hand or left-hand)
b. Set Dip Switch #8 as Master (off)
Run each operator making current sensing adjustments as necessary , as indicated on the Control Board Adjustments page of
this installation guide. When both operators have been adjusted, turn power off, then turn on Dip Switch #8 in the operator
chosen as the Slave.
The timer to close and radio/single button behavior are set in the Master operator.
The following selections are set individually:
Current Sensing
Maximum Run Timer
One-Second Lock Release
Three-Second Pre-Start Warning
Right/Left-Hand Selections
SURGE PROTECTOR INSTRUCTIONS
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
connected to the surge protector, if their protection
line becomes shorted due to a surge over the rating
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
entire surge protector with a new unit.
Do not simply unhook the shorted wire, as this
removes the protection from the circuit that was
saved by the protector in the first place!

CHARGER BOARD SLEEP MODE
When primary AC power is not available, the operator will continue to
operate in battery only mode if the charger board is set in its RUN mode
(see Battery Backup Charger Configuration). Accessories wired into
the operator will continue to draw power, even when the operator is not
opening or closing the gate. This can dramatically reduce the amount of
standby time available from the batteries.
To extend the available standby time, the charger board has a “sleep”
mode feature which will turn off power to all controls except for any that
are wired according to the schematics below. By removing the black jumper
cap JP1 located in the upper right hand corner of the charger board this
feature can be enabled. Af ter fifteen minutes of inactivity , all controls except those wired as shown below will turn off. Those wired as shown will
continue to have power at all times and will upon activation generate first
a “wake” signal that will power all controls back up, and then create either
an open signal or single button signal, depending on how the wire jumper
shown below is connected.

TROUBLESHOOTING
Operator fails to start:
A. If the operator has been running a large number of cycles,
the motor may have gotten hot and tripped the overload.
Allow the motor to cool down and the overload will reset
automatically.
B. Make sure you have power at the master distribution panel
and that the power has not been turned off.
C. The secondary fuse on the control board may have blown.
Replace the fuse (refer to control box parts list on page 30
[SLR & SLC] and page 33 [SLD] for part number information).
Motor operates, but gate does not move:
A. In operators with torque limiters and friction pad clutches,
check for signs of slipping. Y ou can mark the sprocket and
clutch with a yellow or white grease pen and watch for the
lines to move apart if slipping is taking place. Adjust the
torque limiter tighter if this is the problem.
B. Check for broken chain or worn belts.
C. Check all setscrews on pulleys and sprockets and tighten
them if necessary, and check for keys which may have
fallen loose from keyways.
Motor sounds like it is working harder than normal:
A. Make sure the gate is moving freely and without binding
throughout its entire travel.
B. Check the drive chain for obstructions (if the operator has
one).
C. If the operator has an internal brake mechanism, make
sure it is releasing.
Limit switch getting out of time:
A. Check for proper tension on all limit chains to be sure there
is no jumping taking place. Mark one tooth and its corre-
sponding link and run the gate. If the marks have moved,
the chain is skipping.
B. Check the setscrews in limit sprockets for tightness. In
rotary limit boxes, check the rotary limit nut for sloppiness
or stripped threads. Replace if necessary .
C. Check the chain tension along the output sprocket and
idlers. Mark the chain and one tooth of the sprocket as
described above and run the gate. Check for jumping.
Gate stopping part way open or closed
(but no visible obstruction):
A. The control board may have received a false obstruction
input triggered by current sensing set too low. Make sure
the gate moves freely through its entire travel before adjusting the current sensing.
B. The maximum run timer may have counted down and ex-
pired. This can be caused by having the timer set too low ,
if a chain or belt is broken, or if a sprocket or pulley is
slipping. When the timer expires, the gate stops and an
alarm will sound.
C. An obstruction signal from an accessory wired to the ob-
struction input may have triggered falsely . Check the control board for lit L.E.D. indicators for any of the following
inputs: safety, shadow, open obstruction, close obstruction, stop, etc. If any are lit when the operator should be
running, remove all devices hooked to that function and
hook them up one at a time and try to run the operator until
the problem device is found. Refer to page 12 for details on
the control board indicators.
Gate staying open with automatic system:
A. If there are vehicle detectors in your machine which are set
up for reverse, one of your loops or loop detectors may be
sending a false signal. Disconnect the wire harness and
try running the operator.
B. An opening or reversing device may be stuck or malfunc-
tioning. Try disconnecting these devices and hook them
back up one at a time and try running the operator until the
malfunctioning device is found.
C. Make sure the close limit switch isn’t activated. If it is, the
operator will think the gate is already closed.
HOW TO ORDER REPLACEMENT PARTS
Use the part numbers listed on the following pages. Contact your local OSCO dealer or distributor to order parts.
1. Supply the model number and serial number of your operator.
2. Specify the quantity of pieces needed and order by part number and name of part.
3. State whether to ship by freight, truck, parcel post, UPS or air express.
4. State whether transportation charges are to be prepaid or collect.
5. Specify name and address of person or company to whom parts are to be shipped.
6. Specify name and address of person or company to whom invoice is to be sent.

BATTERY MAINTENANCE
The gel-cell batteries in this operator require no routine maintenance. For assured continued performance, they should be
replaced every year.
If power is to be removed for one week or more, disconnect the negative wire from the batteries as this will prevent deep
discharging.
Fully charge before use after storage or upon initial installation.
BRUSH REPLACEMENT
Brushes should be inspected every 100,000 cycles, (200,000 for BGU-D) or
yearly , whichever comes first. The motor has two brushes, one on each side.
B
Original brushes are approximately 3/4” long and should be replaced when
they are 1/4” long, or sooner. If brushes are allowed to wear beyond this point,
permanent damage to the motor may result.
To inspect the brushes, remove retaining cap (A), with straight-blade screwdriver, and carefully pull assembly straight out. Measure remaining brush material (B).
To reinstall, place brush in hold, aligning rounded indentation (C), correctly
with motor shaft. Gently push in spring and align contact with oval carrier , push
in with retaining cap (D). Hold in place and thread cap into brush carrier. Do not
overtighten or cap will crack! Repeat for other brush.
If brushes require replacement, order kit #2510-243.

PREVENTATIVE MAINTENANCE
IMPORTANT!
• Always disconnect power from operator before servicing.
• Keep clear of gate during operation.
GENERAL:
OSCO gate operators are designed for many years of trouble-free operation and, under recommended operating conditions, will
require only minimal maintenance. T o ensure that your unit is ready for operation at all times--and to preclude serious damage
or failure--inspect the unit systematically . Proper adjustments and lubrication should be made as recommended.
LUBRICA TION:
Bearings. For models which have pillow block style bearings with greaseable fittings, lubricate at least twice a year with a
lithium complex based, petroleum oil NLGI 2 rated grease. Oilite and precision sealed bearings do not require additional
lubrication.
Motor. Motors have sealed ball bearings and do not require further lubrication. If bearing noise develops after several years of
operation, bearings should be replaced by a motor repair company , or the motor should be replaced if necessary .
Drive Chain and Sprocket (slide gate models only). The main drive chain and sprockets should be inspected for wear,
cleaned, and wiped down with a lightly oiled rag every six months.
Swing Gate Arm (swing gate models only). Check all bolts for proper tension and tighten if necessary. Make sure the arm
folds overextends itself slightly against the overtravel stop to reduce the chance that the gate can be backdriven open. Adjust the
close limit slightly if additional travel is required. Lightly lubricate all pivot points with a light machine oil.
Barrier Gate Arm (barrier gate models only). Check all bolts for proper tension and tighten if necessary . If the arm has been
warped or damaged, replace as necessary .
ADDITIONAL SIX MONTH PREVENT ATIVE MAINTENANCE:
1. For operators which utilize torque limiting clutches, check
for proper tightness. If there appears to be dust from wear
on the pads, inspect the pads and replace if necessary . If
the clutch cannot be adjusted tightly enough to move the
gate without slipping, the pads must be replaced.
2. For operators with V-belts, inspect for wear and replace
as necessary. Check for proper tension and adjust if required. Check all pulley setscrews for tightness and tighten
if necessary .
3. For operators with internal chain drives, inspect chain and
sprockets for wear and replace if necessary. Check for
proper tension and alignment, and adjust if required. Check
all hub sprocket setscrews and tighten if required.
4. Check limit switches and limit actuators (cams, limit nuts,
etc.) for wear and replace as required. In rotary limit switch
assemblies, wipe the limit shaft clean and apply a light
coating of dry lubricant.
5. For operators with magnetic brakes, check for proper adjustment. Brake disc must run free when the brake is engaged. For brake assemblies other than C-face style, the
brake should be adjusted so that the solenoid plunger throw
is between 3/8” to 1/2”. Too much throw will damage the
solenoid. If the solenoid emits a loud buzzing sound
when the motor is run, the brake must be adjusted.
6. In operators which have a disconnect handle, inspect disconnect handle for proper function and lubricate if necessary . Use a lithium based grease on all moving parts.
7. Inspect all nuts and bolts for proper tightness and tighten
as necessary .
8. Check all reversing devices for proper function. Inspect all
contact edges for wear and replace if required. Check photoeyes for proper alignment and function.
9. Check current sensing for proper adjustment when finished
with inspection and maintenance.
10.Inspect the installation area. Are all the warning signs intact and visible? If they are missing or need replaced, contact OSCO. Be sure there are no control stations mounted
within reach of the gate. Review safety literature with the
customer and advise them to remove any such stations
found.
For slide and swing gate operators, you must inspect
the gate for proper operation. The gate should move
easily without binding through its entire travel. If the
gate does bind, adjust or fix as required. Failure to
keep the gate in good working condition will have
adverse effects on the operator .
