BD BACTEC FX - Isolation Mode

BD BACTEC™ FX Instrument User’s Manual
78
Instrument numbers must be unique in a BD EpiCenter configuration.
LIS configuration is disabled when BD EpiCenter is enabled. The instrument data can be
conveyed to a LIS system through the BD EpiCenter system.
All instruments in a BD EpiCenter configuration must use the same version of instrument software.
Maintenance
The Host Query button on the Maintenance – Test display is disabled when BD EpiCenter is
enabled.
4.12.2 Isolation Mode
Isolation mode is the state that exists when communication between the BD BACTEC FX instrument
and a stack is lost. Isolation mode is designed to enable the stack to continue to collect vial readings.
However, Isolation mode is not intended to enable routine workflow such as entering vials through Vial
Entry, removing positive and negative vials, identifying anonymous vials, etc. Since positivity analysis
occurs at the main computer, no vials transition to Positive or Negative status while the system is in
Isolation mode.
Readings will continue to be taken by the stack(s) while in Isolation Mode, however only the last five
days worth of readings will be sent to the main computer once communications have been
re-established. If the stack remains in Isolation Mode for more than five days, readings will be lost and
a Reading Gap Error may occur.
Please note the following conditions about Isolation mode related to system operation:
• Isolation mode will continue to collect readings until communications with the UIPC is
re-established. However, only the most recent five days worth of readings are maintained. It is
strongly suggested that an instrument not remain in Isolation Mode for a time period greater
than five days, failure to do so may result in Reading Gap errors.
• Each stack can be in Isolation mode independent of the other stack; however this would be a
rare condition.
• The main computer handles the transition of each stack into and out of Isolation mode
independently.
• In Isolation mode, when you open the instrument door no station status indicators are lit.
Routine workflow is not supported in Isolation mode; see Isolation Mode Operation below for
supported operations.
• The main computer displays errors when communication is lost with the stack. Once you
acknowledge the error, the buttons for operations at the isolated instrument (e.g., Remove
Positives button, vial entry button, etc.) do not appear. This serves as a reminder that the
BD
BACTEC FX stack(s) and main computer are not communicating.
• The stack(s) and main computer both return to Directed mode (normal operating state) from
Isolation mode when communication between the two is reestablished. During the transition,
data collected by the stack(s) while in Isolation mode is transferred to the main computer and
processed. Vial positivity is assessed at this time for all vials that remain in the instrument
when recovering from Isolation mode.
• The time required to complete Isolation Mode recovery will vary depending upon the number
of vials in the system and the length of time that the instrument was in Isolation Mode.
