TROUBLESHOOTING
The Digital Gateway has diagnostic features that aid
in troubleshooting door problems. There are status
LEDs and alarm conditions that show you what the
door is doing. The alarm condition explanations and
descriptions of the LEDs will identify problems that
may come up.
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 24
vac will be available at terminal 7. This power can be
used to turn on a 24 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.
