Monitored Errors
Certain components, operating parameters and system
conditions are monitored while the system is powered on,
and during operation, to ensure the instrument is in
operational condition. When a monitored component or
parameter falls outside the established limits or operating
criteria, an alarm sounds continuously until the error is
cleared, and an error number or warning message is
shown on the Tissue-Tek Xpress x120 display. To cancel
(turn off) the alarm, press the EXIT button on the warning
message.
Each error that results in the display of an error number
generates an entry in the system Error Log. The Error Log
stores the 100 most recent errors, arranged by date, and
provides a description of each error (see “Viewing the
Error Log” on page 4.18 for details).
