PROGRAM 3—TERMINAL 26 (N.C. CONTACT)
This input has various functions that are explained in
the programming section of this manual. (See OP-
TIONAL PROGRAMS on page 13.)
The default function is Photoeye AC. A loss of this
connection while the door is closing will immediately
reverse the door to the open position. The door will
remain open as long as something is in the path of the
photoeye beam.
After the obstruction is removed the door will remain
open (if it was originally opened by a non-automatic
activator: A/A, PB1, or Open-Close) until it is closed by
a non-automatic activator. The door will close auto-
matically if it was originally opened with an automatic
activator (Auto or PB1-A/A with A/A Close Delay timer
on).
If the photoeye is activated while either Close Delay
timer is timing down, the timer will reset and resume
timing down after the photoeye beam is cleared.
The photoeye input is inactive while the door is closed
or opening.
LSB (BREAKAWAY KILL SWITCH)—TERMINAL 27
(N.C. CONTACT)
The breakaway kill switches are connected to this
input. If the breakaway bottom bar is hit and comes
apart, the connection to terminal 27 is lost. The Digital
Gateway will turn off the motor contactors and the
door will stop and not operate until the system is reset.
The AJAr message will be displayed and the LSB
LED will blink.
To reset the system: Reassemble the breakaway
bottom bar and press the Open Reset/Jog button on
the Digital Gateway or the Stop input.
LOOP—TERMINAL 29, THREE TERMINAL PLUG
(N.O. CONTACT)
This input is used if a 12 vdc loop detector is used as
an activator. When something is present on the loop a
contact in the detector will close. This maintained
connection will open the door if the door is closed,
closing or stopped between limits. The door will remain
open as long as the connection is present. When the
connection is removed the Auto Close delay timer will
count down and close the door.
The Auto Close delay timer (dEL) 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.
This input operates the same as the Auto input
(terminal 14).
PRIORITY OF INPUTS
Various inputs to the Digital Gateway have priority over
other inputs. The following paragraphs explain how
some inputs affect others:
•
If any other input is activated while the door is
being opened by the Auto input, the new input will
be ignored.
•
If the Auto input is activated while the door is being
opened by the A/A, PB1, or Open input the Auto
input will be ignored.
•
If the RE, Close, Stop, or Program 2 inputs are
activated while the Auto Close delay timer is
counting down, these inputs are ignored.
•
If the A/A, PB1 or Open input is activated while the
Auto Close delay timer is counting down the new
input will immediately take over.
•
If the A/A Close delay timer option is turned on
and the A/A or PB1 input is activated while the
Auto Close timer is counting down the A/A Close
delay timer will immediately take over.
•
If the Auto, Photoeye DC or Program 3 input is
activated while the Auto Close delay timer is
counting down, the timer will reset and start over
when the activator is no longer activated.
•
If the door is open in a normal condition and the
Auto input is activated, the door will remain open
when the Auto input is not present. If another
activator tries to close the door while the Auto
input is on the door will remain open until the Auto
input is not present.
