CONTROLBOX MOUNTINGCONTROLBOX MOUNTING

CONTROLBOX MOUNTING

For dual-leaf applications, both linear drive motors will connect to a single control box. Locate the control box in the vicinity of

eitherlinear actuator motor.Mount the boxfirmly to anon-movable object.Knockouts areprovided for conduits.Do notmount

the control box where a lawn sprinkler may spray water on it.

NOTE: Wheninstalling thecable connecting theoperator to the control box,be sure toleave someslack to allowfor theswing

ofthe gate. Water tight connectors arehighly recommended.

POST/PILLAR BRACKET INSTALLATIONPOST/PILLAR BRACKET INSTALLATION

POST/PILLAR BRACKET INSTALLATION

Severalbrackets havebeensupplied forpost orpillar mounting.The postpillar bracket,operatormounting bracket,and spacer

plate can be combined in various configurations to fit most applications. It is very important to achieve the required mounting

locationforproper operationand toavoid premature failure.

1. Locatethe post pillarbracket verticallyapproximately halfway upfrom the groundrelative to theoverall gateheight.

2. If mounting to a round post of 4” diameter or less, use two U-bolts to attach the post/pillar bracket.

3. Ifmounting toa square post,use eitherthrough boltsor, if applicable,weld thebracket to thepost directly.Avoiddrilling into

mortarjointswherever possible.

4. When mounting to a pillar, anchor the bracket using 1/2” lag bolts and lag bolt anchors. Drill 3/4” diameter holes to a depth

of 4” using a rotary hammer percussion drill. Insert lag bolt anchors for 1/2” diameter lag bolts. Lubricate bolts before

installationand tighten inplace when done.

GATEBRACKETINSTALLATIONGATEBRACKETINSTALLATION

Referto the illustrationon thefollowing page.

1. Openthe gate toapproximately 90 to 95degrees (full open position).

2. Carefullymount the operator to the post/pillar bracket assemblyand hold the frontend of the operatorlevel and in its fully

open position.If necessary, youcan temporarilyapply powerto theoperator toopen itfully. DO NOTALLOW THE DRIVE

TUBE TO SPIN!

3. Line up the gate bracket with the linear actuator and mark the position. Clamp the bracket in place. Once its final position

is set, permanently attach the bracket.

4. Runthe operator to the fully-closed position,adjusting the closelimit as neededto achieve fulltravel. Make anymounting

changesneeded to achievefull travel withoutthe operator bindingagainst the post,gate, etc.

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 or operator

control box.

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!

1 & 4 OPEN Opensthe operator.Several accessories suchas button stations,keypads, trans-

mitters and card readers can be wired to open.

3 & 4 CLOSE Closes the operator. Use caution when wiring accessories to these terminals.

The gate must be clearly visible from the location of any accessories wired

to close.

4 & 5 SINGLE-BUTTON Performs the single-button function which will alternate between open and close

or open, stop and close - depending on dip switch #3. (See page 8for details.)

2 & 4 STOP Stops the operator. If no stop button is used, a jumper is required across 2&4.

4 & 6 REVERSE Thisfunction will cause a reversal when the gate istraveling closed and willtravel

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

reaching a limit, the gate will stop again, and this time will sound the emergency

alarm and lock out.

4 & 51 CLOSE This functionworks exactlylike the OPENOBSTRUCTION, except thatit will only

work in the closing direction.

4 & 11 SHADOW/HOLD Thisfunction will keepthe gate inits fullyopen position whilethe signal ispresent.

This is typically used with a loop and loop detector to keep a large swing gate

open while vehicular traffic is passing through.

CURRENTSENSING ADJUSTMENTSCURRENTSENSING ADJUSTMENTS

CURRENTSENSING 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

movingunder normalconditionswithout interruption.

Priorto adjustingthe operatorcurrent sensingfunctions, makesure the gatemoves freelyin bothdirections. Abadly alignedor

poorlymaintained gatemay causefalse triggeringof the currentsensor. Referto page8when following the instructionsbelow.

Afactory adjustmenttool hasbeen supplied tomake theseadjustments easier.Thistool canbe foundin theinformationpacket.

CLOSEDIRECTION CURRENTSENSEADJUSTMENTCLOSEDIRECTION CURRENTSENSEADJUSTMENT

CLOSEDIRECTION CURRENTSENSEADJUSTMENT

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 gategoing closed. If the operatorstops and reverses, turn the close direction potentiometer

(see page 8) one turn higher, press the STOP button, and try again. Repeat this process until the gate no longer causes false

trippingof thecurrent sensor.Note that eachtime thegate operatorreverses, theSTOP buttonmustbe pressed.Next, turn the

close direction potentiometer lower slowly while the operator is running the gate closed until the gate operator stops and

reversesagain. From thispoint, turn the close direction potentiometer higherby 1 1/2turns. Additional adjustmentby 1/2-turn

increments may be necessary.

MAXIMUM RUN TIMER ADJUSTMENT

This adjustable potentiometer sets the full speed run time for the

operator, as well as the maximum run time. There should be

approximately three seconds of slow speed travel before reach-

ing the end of travel. Maximum run is set automatically as ten

seconds longer than the length of time at full speed. See page 8

for details.

CHARGERBOARDSLEEP MODECHARGERBOARDSLEEP MODE

CHARGERBOARDSLEEP 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

openingor closing the gate. Thiscan dramatically reduce the amountof

standbytime availablefrom 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

arewiredaccordingtotheschematicsbelow.Byremovingtheblackjumper

cap JP1 located in the upper right hand corner of the charger board this

feature can be enabled. In the absence of incoming power sufficient to

change the batteries and operate the controls, the control power will be

shutoffafter15 minutesof inactivity.This will removepower toall acces-

sories except those wired as shown below. Those wired as shown will

continueto havepower atall timesand will upon activation generatefirst

a“wake” signal thatwill powerall controlsbackup, andthen createeither

anopen signal orsingle buttonsignal, dependingonhow thewire jumper

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

connectedto the surge protector, if theirprotection

linebecomes shorteddueto asurge overthe 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

Motor operates, but gate does not move:

A. Makesure all mountinghardware is stillattached andthat

all fasteners are tight.

B. Check that the actuator cylinder is moving. If it isn’t, the

gearsin thedrive mayhave stripped.

Motor sounds like it is working harder than normal:

A. Make sure the gate is moving freely and without binding

throughoutits entiretravel.

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 ad-

justing the current sensing.

B. The maximum run timer may have counted down and

expired. This can be caused by having the timer set too

low. Whenthe timer expires, thegate stopsand an alarm

willsound.

C. An obstruction signal from an accessory wired to the ob-

structioninput may havetriggered falsely.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
