TERMINAL STRIP
The Digital Gateway has plug-in terminal strips along
the left side of the unit. The power, output, and input
connections to the Digital Gateway are made through
this terminal strip. The terminal strip is factory-wired to
a larger terminal strip in the control box. The larger
strip is used for the external connections.
INPUT STATUS LEDS
These lights will show the status of the activator,
safety device or other input connected to the control-
ler. The light will be on if the input has been activated.
(See Figure 2 for an example of an LED.)
If the input requires a normally open (N.O.) con-
tact: The LED will light when the contact closes.
If the input requires a normally closed (N.C.)
contact: The LED will light when the contact opens.

INPUTS TO THE DIGITAL GATEWAY
A0500029
Inputs
Figure 3
NOTE: All DC inputs should be contact closure or
NPN open collector 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 12 vdc which is sup-
plied internally.The ground side of 12 vdc,
provided at terminal 10 (COM) on the Digi-
tal Gateway, 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 all the same.
LIMIT SWITCHES—TERMINALS 8 AND 9 (N.O.
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 full close position.
PB1 (PUSHBUTTON)—TERMINAL 11 (N.O.
CONTACT)
The pushbutton on the control box is connected here.
Pushing the button (a 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.
Refer to the section on setting the timers.
The PB1 input works the same as the A/A input
described in the following.
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.
Refer to the section on setting the timers.
Typical activators include pull cords, pushbuttons, or
radio controls.
This input works the same as the PB1 input as de-
scribed 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 main-
tained 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.
INPUTS TO THE DIGITAL GATEWAY

PHOTOEYE—TERMINAL 15 (N.C. CONTACT)
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.
REVERSING EDGE—TERMINAL 17 (N.C.
CONTACT)
A momentary loss of this connection, such as the door
coming down on 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 enclosure,
or the Close input. The system will reset and the door
will close.
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 display message EdGE
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 for more
information.)
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 off the motor
contactors. It will also send a signal to the Digital
Gateway by closing the contact connected to terminal
18. The display message OLr will 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 pressing 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 input.
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 message LOC will
be on the display and no inputs will be active. Remov-
ing the connection will return the Digital Gateway to
normal operation.
INPUTS TO THE DIGITAL GATEWAY

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.

POWER
The Digital Gateway operates at 115 volts AC. Power
is supplied through terminals 1, 2 and 3. Terminal 1 is
115 vac hot, terminal 2 is 115 vac neutral and terminal
3 is ground. (See Figure 16.)
OUTPUTS
The 3 triac outputs of the Digital Gateway share a
common power source which is terminal 4. Terminal 4
is internally connected to the 115 vac power source.
Terminal 5 is the open output, supplying power to the
open contactor. Terminal 6 is the close output, supply-
ing power to the close contactor. Terminal 7 is the
Program 1 output. It can be used to power a relay
which can be used for a variety of things. See the
programming section.
An RC network and MOV are connected across each
output for noise suppression. An external MOV is
recommended across any contactor coil or solenoid
coil. The maximum rating for each output is 1 amp
inductive continuous. (See Figure 16.)

OPTIONAL PROGRAMS
NOTE:The Digital Gateway has one programmable
output (output 7), two programmable inputs
(inputs 24 and 26) and various other pro-
gram options built in. A description of each
available program follows. See SETTING
THE PROGRAM OPTIONS on page 15 for
programming instructions.
PROGRAM 1, OUTPUT 7
This output can tell you if the door is not closed, fully
open or about to close. When output 7 is turned on
115 vac will be available at terminal 7. This power can
be used to turn on a 115 vac relay which can indicate
where the door is or what it is about to do. The relay
can operate warning lights, horns or signal an energy
management system. Only one of the three options
available in Program 1 can be selected at a time.
Door Not Closed, P1 = LSC
Output 7 will be on when the door is not closed. (Not
on the "Close" limit switch). The output will be off when
the door is fully closed. (On the "Close" limit switch).
This is the factory default setting. It tells you the door
is not closed.
Door Open, P1 = LSO
Output 7 will be on when the door is fully open. (On
the "Open" limit switch). The output will be off when
the door is below the open position. (Off of the "Open"
limit switch). It tells you the door is fully open.
Delay to Close, P1 = dtC
When the door is signaled to close, output 7 will turn
on, the Delay to Close timer (dtC) will start, but output
6, which closes the door will not be on. When the
Delay to Close timer times out, output 6 will activate
and the door will close. Output 7 will remain on until
the door is completely closed. Maximum time is 15
seconds. This option tells you the door is about to
close.
PROGRAM 2, INPUT 24
This input can be used to place the Digital Gateway
into an inactive condition, operate the door manually or
automatically or open the door to a height below fully
open. Only one of the Program 2 options can be
selected at a time.
LOC Condition, P2 = LOC
When input 24 is on and the door is fully closed the
Digital Gateway will go into an inactive condition. No
inputs will be able to activate the door. The message
LOC will be on the display. Once the connection is
removed from the input, the system will be ready for
normal operation. This is the factory default Program 2
setting and can be used to "lock out" the door.
MAN-AUTO Selector Switch, P2 = SSA
If this option is selected, a manual-automatic two
position selector switch can be connected to input 24.
When the switch is in the MAN position (there is no
connection at terminal 24) the A/A and Auto Close
delay timers are disabled. The Auto and Loop inputs
are inactive when the door is closed, but will reverse
the door if it is closing or hold it open when it is fully
open.
When the switch is in the AUTO position (there is a
connection at input 24) the A/A Close Delay timer will
turn on and all inputs will operate normally.
This option allows you to operate the door manually or
automatically.
MAN-AUTO Selector Switch with Open and Close
Inactive in Auto, P2 = SSb
This option operates the same as the MAN-AUTO
option described in MAN-AUTO Selector Switch, P2 =
SSA, except in the Auto position the Open and Close
inputs are inactive.
Passage Entry—Timed, P2 = Pet
When this option is used and the door is activated to
open with input 24, it will open for a predetermined
time. This allows you to open the door part way with an
activator connected to terminal 24 while other activa-
tors connected to other inputs will open the door
completely. A 20 foot door could be opened 8–10 feet
for small loads and 20 feet for large loads.
When input 24 is activated while the door is fully
closed the door will open and the Passage timer (PEt)
will begin counting down. When the Passage timer
reaches zero the door will stop. Activating this input
again will close the door. If the A/A Close Delay timer
is on when the door is opened with input 24, the door
will open until the Passage timer reaches zero. Then
the A/A Close Delay timer will time out and close the
door.
OPTIONAL PROGRAMS

14
Passage Entry—Position, P2 = PEP
When this option is turned on PROGRAM 3, INPUT
26—Passage Limit Switch, LSP will also be turned on.
These two options allow you to open the door partially
using an activator connected into input 24 and another
limit switch (Passage Limit LSP) connected to input
26. A 20 foot door could be opened 8 feet for small
loads and 20 feet for large loads. The Passage Limit
would be set at 8 feet. Using the activator connected
to input 24 would open the door to the Passage Limit.
Using the other activators would open the door com-
pletely.
When input 24 is activated while the door is fully
closed it will open until it reaches the Passage limit
switch which will activate input 26. When input 24 is
activated again the door will close. If the A/A Close
Delay timer is used the door will open until it reaches
the Passage limit switch, then the A/A Close Delay
timer will time out and close the door. If the input is
activated while the door is closing the door will open
until it reaches the OPEN or Passage limit switch,
depending on which limit switch is tripped first.
PROGRAM 3, INPUT 26
This program option will not appear in the Program
Menu. These options are set through factory defaults
or by other program options.
Photoeye AC
This input will operate the same as the photoeye input
described in PHOTOEYE—TERMINAL 15 (N.C.
CONTACT) on page 5, except it would be used for AC
photoeyes. This is the factory default setting.
Passage Limit Switch, LSP
This option is turned on when the Passage Entry—
Position option is turned on. The Passage Limit switch
is connected to this input. When the door reaches the
Passage position after it is opened by input 24, this
input will be activated and the door will stop.
PROGRAM 4, PROGRAMMABLE OPTIONS
This program section allows you to change the Open
and Close inputs to constant pressure/jog, set a
reverse delay timer and/or a loop call delay. More than
one of these options can be on at the same time.
Close Jog, CLJ = On/CLJ = OFF
This option converts the Close Input (input 21) to
constant pressure/jog operation. The door will only
close while the input is activated.
Open Jog, OPJ = On/OPJ = OFF
This option converts the Open Input (input 20) to
constant pressure/jog operation. The door will only
open while the input is activated.
Reverse Delay, rdt = 00
The Digital Gateway is programmed to immediately
reverse the door if an activator or safety input is
operated while the door is closing. This option can be
used to delay the reversal of the door. If the A/A, Auto
or Open input is activated while the door is closing the
reversal will be delayed by the time set on the Reverse
Delay timer. The door will stop, the Reverse Delay
timer (rdt) will time out and the door will then open.
Reversals due to the photoeye or reversing edge
inputs will not be delayed.
The maximum setting is 15 seconds. The factory
default setting is 0 which disables the timer.
Loop Call Delay, LPt = 00
This option will delay the opening of the door when it is
opened by the Loop input. This can be used for cross
traffic situations.Traffic crossing in front of the door will
not remain on the loop long enough to open the door
but traffic approaching the door will activate the door.
When the Loop input is activated while the door is fully
closed the Loop timer will count down and then open
the door. If the Loop input returns to the normal
unactivated state while the timer is counting down the
door will not open and the system will return to the
normal state.
If the Loop input is activated while the door is closing
the door will immediately reverse to the fully open
position.
The maximum setting is 15 seconds. The factory
default setting is 0 seconds which disables the timer.
PROGRAM 5, REVERSE INPUT LOGIC
This option can be used to reverse the required logic
for some of the inputs. The required contact arrange-
ment can be changed from normally closed (N.C.) to
normally open (N.O.). The inputs that can be changed
are Open Limit (LSO - #8), Close Limit (LSC - #9),
Photoeye—DC (Pdc - #15), Reversing Edge (rE -
#17), Stop (StP- #23), Program 3 (PG3 - #26) and
Breakaway Limit (LSb - #27).
PROGRAM 6
This program option is set for factory use. It requires
an additional three digit security code. If you find
yourself in program 6 press the Set button to return to
the main menu.
