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. -9-3-05-8 SLR • SLC • SLD OPERATOR INSTALLATION GUIDE TERMINAL CONNECTION DESCRIPTIONS TERMINALS FUNCTION DESCRIPTION OF FUNCTION 24VAC 24VAC Provides 24Volt AC power for accessories. 24VAC N Note: DC models will NOT have 24Volt AC power available. 24VDC+ 24VDC Provides 24Volt DC power for accessories. 24VDC- COMM. 1 & 4 OPEN Opens the operator. Several accessories such as button stations, keypads, transmitters 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 9 for details.) 2 & 4 STOP Stops the operator. If no stop button is used, a jumper is required across 2&4. 4 & 6 REVERSE This function will cause 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 OBSTRUCTION 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 function works exactly like the OPEN OBSTRUCTION, except that it will only OBSTRUCTION work in the closing direction. 4 & 11 SHADOW/HOLD This function will keep the gate in its fully open position while the signal is present. This is typically used with a loop and loop detector to keep a large swing gate open while vehicular traffic is passing through. 24VDC+ & 60 RUN/PRE-START A 24Volt DC device such as a strobe light or alarm can be wired to these terminals. 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.) 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! -10 - 3-05-8 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 page 9 when following the instructions below. A factory adjustment tool has been supplied to make these adjustments 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 STOP 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 ...
