AUTOMATIC GATE OPENER • Installation Manual24Brick, Masonry, or Rock ColumnInstallationSpacing requirements may prevent mounting the gateopener (actuator) on a column (see fig. 36). If this is thecase, the gate may have to be professionally re-hung ona post next to the column.When mounting the gate opener (actuator) onto a col-umn, use of the push-to-open bracket (sold separately)may be necessary to ensure proper spacing betweenthe column and the opener.If the proper spacing cannot be achieved using thepush-to-open bracket, the gate opener (actuator) mustbe installed using the push-to-open procedure (seepage 22).If using the push-to-open procedure, ensure that thegate does not cause a traffic hazard.CONTROL BOARD SETTINGSYou have several optional gate opener settings that arecontrolled via the DIP switches located inside the con-trol box.DIP Switch Settings and Descriptions(fig. 37)DIP Switch 1 – Soft Start/StopThe soft start and stop function slowly starts the gate asit begins to move, and slowly stops the gate as it beginsto stop. If used, this feature may prolong the life of yourgate opener system, due to less wear on the actuator(opener).DIP Switch 2 – Warning BuzzerThe warning buzzer provides several different alarms.When the gate begins to move, the warning buzzer willsound an alarm for two seconds. It also sounds analarm when an obstruction occurs twice in any givencycle. The obstruction alarm cannot be disabled byturning this DIP switch to the OFF position.DIP Switch 3 – Automatic CloseWhen this DIP switch is in the ON position, the gate willautomatically close after a period of time. The length oftime is determined by DIP switches 6 and 7. When thisDIP switch is OFF, the gate will stay open until a signalis sent to close the gate. The signal can come from atransmitter, keypad, or push button control.DIP Switch 4 – Push- or Pull-to-OpenThis switch is defaulted to the OFF position as that is thesetting for Pull-to-Open. Pull-to-Open is where the gateswings into the property. When the switch is in the ONposition, the system will work in Push-to-Open applica-tions or when the gate swings out from the property.DIP Switch 5 – Momentary or Constant PressureThe default position is OFF. This switch should be left inthe OFF position unless a constant pressure push but-ton device is being used. This is typically done when agate attendant or guard is operating the gate. The gatethen can only be opened when constant pressure isapplied to a push button device.DIP Switch 6 and 7 – Delay Time for AutomaticCloseSetting these two switches in a specific configurationwill determine the delay time before the gate will auto-matically close. DIP switch 3 must be in the ON positionfor these two switches to be in effect. See the accompa-nying table for settings.DIP Switch 8 – Not UsedFigure 36GateCONTROL BOX SETTINGPivot bracketGate hingePoint AThe distance from the pivot bracket to point “A” +the distance from the gate hinge to point “A”,CANNOT exceed 12”.
