To reset the system and leave the door open:
Activate the Stop input or push the Open Jog/Reset
button on the Digital Gateway. The system will reset
and the door will remain open.
This input is inactive when the door is opening or
when the door is closed (on the close limit switch).
A loss of this connection for two seconds while the
door is open (LSO on) will keep the door from closing.
This is an alarm condition. The EdGE message will be
displayed and the reversing edge LED will blink.
To reset the system:
Re-establish the connection,
then push the Open Jog/Reset button, or the Stop
input. (See ALARM CONDITIONS on page 9.)
OLR (Overload Relay)—Terminal 18 (N.O. Contact)
When the overload relay in the control box detects a
motor malfunction it will trip and turn the motor
contactors off. It will also send a signal to the Digital
Gateway by closing the contact connected to terminal
18. The OLr message will be displayed and blink and
the OLR LED will be on.
Once the malfunction has been corrected and the
overload reset, the OLR LED will go out, but the
Alarm Condition message OLr will continue to blink
until the system is reset. Reset the system by press-
ing the Open Jog/Reset button or the Stop input.
Open—Terminal 20 (N.O. Contact)
A momentary connection while the door is closed,
closing or stopped between limits will open the door.
This input is ignored during the opening cycle.
Close—Terminal 21 (N.O. Contact)
A momentary connection while the door is opened or
stopped between limits will close the door. This input
is ignored when the door is closed or during the
opening cycle.
Stop/Reset—Terminal 23 (N.C. Contact)
A momentary loss of this connection will stop the door
while it is opening or closing when the door was
activated by the Open or Close inputs.
This input can also be used as a remote reset for
Alarm Conditions. It will reset the system the same as
the Open Jog/Reset button.
Program 2—Terminal 24 (N.O. 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 the LOC command. When a
connection is present and the door is closed (LSC on)
the Digital Gateway will be idle. The LOC message
will be displayed and no inputs will be active. Remov-
ing the connection will return the Digital Gateway to
normal operation.
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 the object is in the path of the
photoeye beam.
After the obstruction has been removed the door will
remain open (if it was originally opened by a nonauto-
matic activator: A/A, PB1 or Open-Close) until it is
closed by a nonautomatic activator. The door will
close automatically 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 has been
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 Jog/Reset button on
the Digital Gateway or the Stop input.
