Display Unit Maintenance - Honeywell VXP System Maintenance Manual

ACTION
EXPLANATION
NUMBER
A017 Database Lost.
The entire VXP database and all database files were lost. The system will
automatically create a new database system and newly acquired data will be
logged. This problem should be reported to Chadwick-Helmuth along with the
downloaded Fault Log. (NOTE: This error will occur any time the internal
battery dies or is removed.)
A018 Signal Error.
An input signal was corrupted. This is normally a transient problem caused by
EMI, etc. The user will be prompted for retry if in menu mode. Otherwise, the
problem will be logged and data acquisition internally retried by the VXP
software. Occasional occurrences of this error do not constitute a system
problem, but if the error reoccurs through many power cycles, then the Fault
Logs should be saved and Chadwick-Helmuth contacted.
A019 Monitor Log Integrity Error.
A record in the vibration monitor log was corrupted. Only the corrupted record is
lost upon download of log to the DU resulting in the loss of the data from one
monitor log cycle (approximately 2 minutes of data). No user recovery
procedures are necessary.
A020 Battery Low/Dead.
The SRAM hold-up battery is low or dead. Consult message in error log to
determine battery condition. If battery is "low", then download any needed VXP
logs to the DU, and contact Chadwick-Helmuth. If battery is "dead", then contact
Chadwick-Helmuth. Note that under the "dead" battery condition, the system will
still run normally but all VXP log files will be lost at each power-down cycle.
Recorded data may be preserved by downloading it before power is removed
from VXP.

4.4.3 Display Unit Maintenance

The display unit is a Pentium computer. As such, certain maintenance tasks should be performed
on a regular basis.
The fixed disk in the Display Unit should be given regular maintenance through the Windows 98
operating system. Such maintenance should include emptying the Recycle Bin, defragmenting the
disk, and running ScanDisk to check for anomalies. The Disk Defragmenter and ScanDisk options
are available under Accessories, System Tools, from the main Windows 98 Start Menu. To get to
the Start Menu, close the VXP program by either clicking on the X at the upper right hand corner,
or choosing File, and Exit from the Menu.
