WIRING CONTROL WIRING OPEN INPUT Any device that is used to open the gate from a closed position is an open input device. The device used must provide normally open contacts. These normally open contacts are connected to terminals 5 and 6. These open input terminals will cause the gate operator to open and/or close if the timer switch is in the OFF position. If the timer switch is in the ON position, these open input terminals will cause the gate operator to open and will hold the gate open until the input is released and the auto close time has elapsed. Figure 5 CLOSE INPUT Any device that is used to close the gate is a close input device. The device used must provide normally open contacts. These normally open contacts are connected to terminals 9 and 10. These close input terminals will cause the gate operator to close the gate any time the gate is in a non-closed position and can be used to override the timer and close the gate prematurely. Push Buttons, Key Switches, etc. SAFETY OPEN PULSE OPEN N.C. STOP INPUT Any device that is used to stop the gate operator while it is N.C. STOP running in the open or closed direction is a stop input device. CLOSE These stop input devices must provide normally closed N.O. STOP contacts. To connect these normally closed contacts, remove Remove jumper the stop jumper from terminals 8 and 9 and then connect the if using N.C. Stop contacts to these same terminals 8 and 9. N.O. STOP INPUT This input functions identical to N.C. Stop with the exception that it requires normally open contacts. These contacts are connected to terminals 9 and 11. SAFETY INPUT Any device that is used to open and/or hold open the gate while the gate is in a non-closed position is a safety input device. The safety input device must provide normally open contacts. These contacts are connected to terminals 4 and 6. This function is especially useful when the auto close timer is being used in preventing the gate from accidentally closing on a vehicle. PULSE OPEN INPUT This input functions similarly to the standard open input with the exception that it will not hold the gate open if the input remains present. This feature will add additional security to the gate operator system in the event that there is a device that is stuck on. Pulse open is found at terminals 6 and 7. 15
