Universal Control Programming
Operating Screen Descriptions
The liquid crystal display (LCD) located in the center of
the control panel is normally blank during the daily
operation of the machine. The display is activated when
the SEL button or the Manager's Menu is selected. The
LCD screen will also alert the operator of specific faults
detected by the control.
Power Up Memory (Initializing)
The seven-segment display should display 00 during the
initializing sequence.
When the machine is powered, the control system will
initialize to perform a system check. The screen will
display Initializing. There will be three types of data the
system will check: Language, System Data, and Config
Data.
Language Initialization
The universal control (UVC) platform supports multiple
languages by keeping specific strings in battery backed
random-access memory (RAM). After power-up or a
central processing unit (CPU) reset, the strings are
tested to see if the language strings are present and not
corrupted. If the strings are present and not corrupted,
initialization continues. Otherwise, the operator is
prompted to select a language. While language strings
are being checked for integrity, the following screen is
displayed.
Figure 2-1
Note:
If there is a language initialization fault, the
machine will force a language selection prior to the
initializing sequence. The standard menu LEDs should
light, as if it were in a menu. If a language has been
selected, the machine is powered down. The machine
should not ask for a language unless there is another
language initialization fault. English is the factory default
setting.
System Data
System data is protected separately from the rest of the
data in memory. System data includes variables that
change frequently, such as the mode the machine is in,
lockout status, serving counters, fault codes, and others.
While System Data is being checked the following screen
is displayed.
Figure 2-2
If the System Data is corrupted, the machine is set to
OFF, the serving counters are set to zero, and the faults
are cleared. A SYSTEM CRC ERR fault is set and
displayed on the LCD. An acknowledgment is required
(press SEL button).
Configuration Data
Configuration data is separate from the rest of the data in
the memory. Configuration data is information entered
through operator and service menus. While the
Configuration Data is being checked, the following
screen is displayed.
Figure 2-3
If the Configuration Data is corrupted, all user and
service settings are set to defaults. A CONFIG CRC ERR
fault is set and displayed on the LCD. The system will
continue to operate in its previous mode, but according to
default settings.
After the memory integrity has been tested, the Safety
Timeout screen will be displayed.
Once the system has initialized, the number of hours
since the last brush cleaning is indicated on the control
panel. The SAFETY TIMEOUT screen will be displayed
with the alarm on for 60 seconds, or until any control
button is selected.
