Becausethe chainhoist ontheModel JH-DCis centrally
located, there is no need to modify the assembly when
changingright- andleft-handinstallations.
WALL MOUNTING
Generally,the operatorshouldbeinstalledbelowthedoor
shaft(see Figure1on previouspage)and ascloseto the
door as possible. The optimum distance between the door shaft and the operator output shaft is 12-15 inches. A greater
distancecan beallowed ifconditions preventinstallation asprescribed.
1. Using the center line of the door shaft as a reference point, locate six mounting holes as shown in Figure 3 on this page.
2. Fora secureinstallation,the operatorshouldbe mountingusing1/2” throughbolts.If thewallconstruction prohibitstheuse
of through bolts, lag bolts and shields of sufficient size may be used. At this point, hand-tighten the bolts only.

JH-DCOPERATORINSTALLATIONGUIDE
The limit nuts are not preset at the factory and must be adjusted for the height of the door 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. Remove
the cardboard filler before attempting to adjust the limit nuts.
With the door connected to the door 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 door by hand to within a foot of its fully open position.
Once the door 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.
Once the open limit nut is set, repeat the above process for the close direction nut, (and LSC-1 limit switch).
After finishing the initial limit nut adjustments, reposition the door 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 door begins to close
instead of open, stop the door. Locate the motor board in the operator control box with terminals M1 and M2 (motor leads) on it. Swap
these two wires to reverse rotation. Observe the door 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 door stops in midtravel,
the open or close current sensor adjustment or the maximum run timer may need adjustment (see page 13).
LIMITNUTADJUSTMENTS
OSCO has also supplied two auxiliary limit switches that can be used to control a variety of
devices. Consult the operator wiring diagram for additional details.
The switches are rated 250VAC, 3 amps maximum.

TROUBLESHOOTING
Operatorfails to start:
A. Makesure youhave poweratthemaster distributionpanel
andthat thepower hasnot beenturned off.
B. Thesecondary fuseonthe controlboardmay haveblown.
Replacethe fuse(refer tocontrolbox partsliston page23.
Motor operates, but door does not move:
A. Inoperators withtorque limitersand friction padclutches,
check for signs of slipping. You can mark the pulley and
clutchwith ayellow orwhite greasepen andwatch forthe
lines to move apart if slipping is taking place. Adjust the
torque limiter tighter if this is the problem.
B. Checkfor brokenchain orworn belts.
C. Check allsetscrews onpulleys andsprockets andtighten
them if necessary, and check for keys which may have
fallenloose fromkeyways.
Motor sounds like it is working harder than normal:
A. Make sure the door is moving freely and without binding
throughoutits entiretravel.
B. Checkthe drivechain forobstructions (ifthe operatorhas
one).
Limit switch getting out of time:
A. Checkfor propertension onalllimitchains tobesurethere
is no jumping taking place. Mark one tooth and its corre-
sponding link and run the door. If the marks have moved,
the chain is skipping.
B. Check the setscrews in the limit sprockets for tightness.
In rotary limit boxes, check the rotary limit nut for sloppi-
ness or stripped threads. Replace if necessary.
C. Check the detent plate in the limit switch box to see that
theedge ofthe detentplateis insertedintothe V-grooveof
both nylon limit nuts (see page 5).
Door stopping part way open or closed
(but no visible obstruction):
(Also see page 13 for additional information regarding
control board adjustments)
A. The control board may have received a false obstruction
input triggered by current sensing set too low. Make sure
the door moves freely through its entire travel before ad-
justing 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 door stops and the
stop button must be pressed to reset the operator.
C. An obstruction signal from an accessory wired to the ob-
structioninput mayhave triggeredfalsely.Check thecon-
trol board for lit L.E.D. indicators for any of the following
inputs: safety, shadow, open obstruction, close obstruc-
tion, stop, etc. If any are lit when the operator should be
running, remove all devices hooked to that function and
hookthem uponeat atimeand trytorun theoperator until
theproblemdevice isfound. Referto page17 fordetailson
thecontrol boardindicators.
Doorstaying open withautomaticsystem:
A. If there are vehicle detectors in your operator which are
connected to reverse, one of your loops or loop detectors
may be sending a false signal. Disconnect the wire har-
ness by pulling harness off the loop detector and try run-
ningthe operator.
B. An opening or reversing device may be stuck or malfunc-
tioning. Try disconnecting these devices and hook them
backup oneata timeandtry runningtheoperator untilthe
malfunctioningdeviceisfound.
C. Make sure the close limit switch isn’t activated. If it is, the
operator will think the door is already closed.
HOW TO ORDER REPLACEMENT PARTS

SINGLE-BUTTON
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 door.
Do not adjust the circuit board current sensing feature too high. It should be adjusted high enough to keep the
door from falsely triggering the sensing, but no higher than necessary for the door to operate. Do not defeat
the purpose of this function!
Although both open and close sensing is provided as an integral part of the door operator, OSCO always
recommends use of reversing edges and photo electric units.

CURRENTSENSINGADJUSTMENTS
Because doors 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
shouldbe setlightenough tomaintain minimalforce(15-25 lbs.)shouldan obstructionoccur,but highenough tokeepthe door
movingunder normalconditions withoutinterruption.
Prior to adjustingthe operator current sensing functions,make sure thedoor moves freely in bothdirections. A badly aligned or
poorlymaintaineddoormay causefalsetriggering ofthe currentsensor.Refer topage 13 whenfollowing theinstructionsbelow.
Afactory adjustmenttool hasbeen suppliedto makethese adjustmentseasier. Thistool hasbeen tapedto thecontrol boxfor
yourconvenience. CLOSEDIRECTIONCURRENTSENSEADJUSTMENT
When the door operator leaves the factory, it has been preset for a relatively light door function and will require additional
adjustment.Begin bystarting thedoor goingclosed. Ifthe operatorstops andreverses, turnthe closedirection potentiometer
(seepage 13) oneturn higher, press the STOP button, andtry again.Repeatthis processuntil thedoor nolongercauses false
trippingof thecurrentsensor. Notethateach timethedoor operatorreverses, theSTOP buttonmustbe pressed.Next, turnthe
close direction potentiometer lower slowly while the operator is running the door closed until the door 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.
OPENDIRECTIONCURRENTSENSEADJUSTMENT
Repeatthe sameprocesswith theopen directionpotentiometerwhile runningthedoor inthe opendirection.Once thisisdone,
run the door through several complete cycles and make sure the door does not false trip in either direction.
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 door fully open or closed, plus an
additional 15 seconds. See page 13 for details.
AUTO CLOSE TIMER ADJUSTMENT
This adjustable potentiometer sets the length of time which
elapses before the door operator automatically closes the door,
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 13 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 mas-
ter and slave operators. You must use Belden 8760 Twisted
Pair Shielded Cable (or equivalent) only – OSCO part number
2500-1982, per foot). See page 13 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.
BATTERYBACK-UP
FOR DC MODELS ONLY
CHARGERBOARDCONFIGURATION
To set the voltage monitor, see the picture below. The RUN posi-
tion willmonitor the voltageofthebatteryonly after AC voltagehas
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!

Right/Left-HandSelections
CHARGERBOARD SLEEPMODE
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
openingor closing thegate. Thiscan dramaticallyreduce theamount of
standbytime availablefrom thebatteries.
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
arewiredaccordingtotheschematicsbelow.Byremovingtheblackjumper
