Alarm recovery tools
• Alarm reset commands; these may include active instrument reactions such as opening valves for a
controlled period to release pressure.
• Several options for product recovery are available through MES commands:
– Re-start the protocol at a specified step. The protocol can contain dedicated blocks of code
independent of the main process.
– Download a new protocol and start it at a specified step
– Start running the settings of a single step in the existing protocol.
• The MES can also log in a qualified user with administrative privileges to run the instrument from
the Rotea
™
GUI as a manual intervention.
– All actions are recorded in the history files and instrument status is reported to the MES
– To return to MES managed operations, the administrator user logs out of the MES. The MES
then logs in as
ViewUser
again. (The instrument can be running the protocol while users/MES
log in and log out.)
