This is the Diagnostic I/O screen. It can be
found by pressing the Select Category but-
ton under the word I/O on the Dryer
Diagnostics (screen 91). By pressing the
Select Category button under Digital, the
user can access the digital outputs (screen
98) and view the status of the digital
inputs (screen 99). The analog diagnostic
I/O function is not used.
This screen is used to enter the diagnostic
mode where outputs can be turned on
(screen 98). Note that the dryer MUST
NOT BE RUNNING to enter diagnostics.
This is an example of one of the digital
outputs that can be manually energized.
All screens in this section only work when
the dryer is not running and is in “stand-
by”. The outputs can be turned on, turned
off, or energized for a 3-second jog (auto-
matically turned on for 3 seconds then
turned off). The process and regeneration
heaters can only be jogged for 3 seconds,
and the index motor, if jogged, will rotate
the wheel for 3 seconds. If the stop button
is pressed at any time during this testing,
the output will stop immediately.
This is an example of one of the digital
input screens. This will show if the input
is open or closed.
