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.
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.
N.C. STOP INPUT
Any device that is used to stop the gate operator while it is
running in the open or closed direction is a stop input device.
These stop input devices must provide normally closed
contacts. To connect these normally closed contacts, remove
the stop jumper from terminals 8 and 9 and then connect the
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.
