Descriptions
______________________________
The fluorescent display 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 key or the Manager's Menu is
selected. The display screen will also alert the
operator of specific faults detected by the control.
Power Up Memory (Initializing)
When the machine is powered, the control system
will initialize to perform a system check. The screen
will display “INITIALIZING”. There are four types of
data the system will check: LANGUAGE, SYSTEM
DATA, CONFIG DATA, and LOCKOUT DATA.
If the power switch is on and the system detects
corrupt data during “Initializing.....”, the detected
faults will be displayed for acknowledgement after
the “SAFETY TIMEOUT” display. The faults may be
“CORRUPTED LANGUAGE,” CONFIG CRC ERR,”
“SYSTEM CRC ERR, “FAULT HISTORY,
”LOCKOUT CRC ERR,” or “POWER FAILURE.”
Once the system has initialized, the number of days
remaining before the next required brush cleaning is
indicated on the control panel and the SAFETY
TIMEOUT screen is displayed with the alarm turned
on. (See Figure 7.)

The SAFETY TIMEOUT screen will be displayed
