INPUTS TO THE DIGITAL GATEWAY
AC INPUTS
(Figure 3)
NOTE: All AC inputs should be contact closure or
solid state connections only. RC networks,
MOV's or noise suppression devices allow-
ing leakage current may cause the inputs
to become active and should be removed.
All inputs operate at 24 vac. The hot side
of the 24 vac, provided at terminal 1 in the
control box, is connected to one side of
the input contact (limit switch, activator,
etc.). The other side is connected to the
proper input. Terminals 10, 13, 16, 19, 22,
25 and 28 are not used.

Limit Switches—Terminals 8 and 9 (N.C. Contact)
Once the door has started, it will move until it is shut
off by one of the limit switches or a backup timer.
OPEN (LSO)
The LSO LED will be ON when the door has reached
the full open position.
CLOSE (LSC)
The LSC LED will be ON when the door has reached
the closed position.
PB1 (Pushbutton)—Terminal 11 (N.O. Contact)
The pushbutton on the control box is connected here.
Pushing the button (momentary connection) while the
door is closed, closing or stopped between limits will
open the door. Pushing the button while the door is in
the full open position will close the door.
The PB1 input can be converted to automatic closing.
(See SETTING THE TIMERS on page 8.)
The PB1 input works the same as the A/A input as
described below.
Alternate Action Inputs (A/A Momentary Contact
Activators)—Terminal 12 (N.O. Contact)
A momentary connection while the door is closed,
closing or stopped between limits will open the door. A
momentary connection while the door is in the full
open position will close the door.
The A/A input can be converted to automatic closing.
(See SETTING THE TIMERS on page 8.)
Typical activators include pull cords, pushbuttons or
radio controls.
The input works the same as PB1 input as described
above.
Auto Inputs (Maintained Contact Activators)—
Terminal 14 (N.O. Contact)
A maintained connection while the door is closed,
closing or stopped between limits will open the door.
The door will remain open as long as the connection
is present. When the connection is removed, the Auto
Close delay timer (dEL) will count down and close the
door.
The Auto Close delay timer will reset if another
maintained connection is made while the timer is
timing out. If you require no closing delay, set the
timer to 0.
Typical activators include floor loops and motion
detectors.
Reversing Edge—Terminal 17 (N.C. Contact)
A momentary loss of this connection, such as the
door making contact with something while it is closing,
will immediately reverse the door to the open position.
The door will remain open and the Digital Gateway
display will read EdGE until the system is reset.
To reset the system and close the door:
Activate
an A/A activator, the pushbutton (PB1) on the enclo-
sure, or the Close input. The system will reset and the
door will close.
