Refer to the photo on page 7 when following these instructions.

Adjustthelimitnutsbydepressingthedetentplateandturningthenutsinthedesireddirectionoftravel. To allow for additional

travel in the open direction, for instance, rotate the open limit nut so that it moves to the left on the shaft. To allow for greater

travel in the close direction, rotate the close limit nut so that it moves to the right on the shaft.

Special Notes for Setting Speeds using LSO-2 & LSC-2:

LimitswitchesLSO-2andLSC-2control when theoperatoracceleratestomaximumspeedanddecelerates to minimumspeed.

It is recommended that LSO-2 and LSC-2 are adjusted first* so the gate slows to near stop before hitting LSO-1 or LSC-1 as

*Theseareadjusted by slightly loosening the two screws which holdtheminplaceandslidingtowardorawayfromthecenter

of the limit box. Care must be taken not to adjust too close to the center as the limit nut may travel past the switch and start

accelerating at the end of the cycle.

CHAIN SUPPORTSCHAIN SUPPORTS

CHAIN SUPPORTS

When necessary, due to the length of the gate and chain, chain supports should be added to the gate at equally spaced

distances to allow the chain to sag as little as possible. A bolt located one inch below the chain line should be adequate.

Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically,

providednoopen,reversingor obstruction signalsarepresentfromthefully-openposition. This timerisadjustablefrom0to124

seconds. This feature is turned on or off using dip switch #1.

Maximum Run Timer Adjustment: This270-degree adjustable potentiometer will signaltheoperatortostop 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.

Close Direction Current Sense Adjustment: This multiturn potentiometer is used to calibrate the built-in current sensing

featurefordetectionof obstructions while running in the closed direction.

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

intheON position, these devices will start approximately two seconds priortotheoperatorstarting.IntheOFF position,

thedeviceswill only work while the operator isrunning.

#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 Thisswitchdeterminesright-handvs. left-handbehavior.Whenlookingfrom insidetheprotectedareatowardthe gate,the

#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 (3) seconds. In the OFF position the reverse delay is one and a half (1 1/2)

seconds.

#7 Not used at this time.

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!

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

This adjustable potentiometer sets the length of time which elapses before the gate operator automatically closes the gate, from

switch selection. See page 10 for details.Do not use the auto close timer without an appropriate reversing device

installed!

MASTER/SLAVECONNECTIONMASTER/SLAVECONNECTION

MASTER/SLAVECONNECTION

Athree-wire shielded conductor cable is required to connect master and slave operators. You must use Belden 8760Twisted

Pair Shielded Cable(orequivalent) 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.

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.
