Start maintenance operations on the Instrument Maintenance screen.
Maintenance operations are disabled while an experiment is in progress.
After maintenance operations are completed and the maintenance (MNT) chip
is ejected, the instrument state changes to Power Up. If the instrument is shut
down as part of a maintenance operation, it should be powered down
immediately after the operation is complete.

When an MNT chip is in place, the buffer flow rate is 25 μl/min at a constant
flow, which will consume 216 ml buffer in a 24 hr period. During extended time
periods with an MNT chip in place, Bio-Rad recommends switching the buffer
to a full bottle of distilled deionized water to avoid wasting buffer and to
eliminate the risk of running the system dry.

There are three types of shutdown; immediate, long-term, and software-only.
See Shutdown Procedures on page 166 for more information on shutting
down the instrument properly.
The shutdown maintenance operation should be performed any time the
application is closed with the instrument connected. Shutdown ejects the
sensor chip, if necessary, and prepares the instrument to be powered down.
The instrument state changes to Shutting Down while performing the
shutdown operations. If ProteOn Manager software remains open, the
instrument returns to the Inactive state. The instrument cannot be
reconnected in this state.
To reconnect the instrument:
• Turn off the instrument, turn it on again, wait 2 min, and restart
ProteOn Manager software
If an instrument fault is reported during a shutdown operation, the shutdown
procedure aborts without completing the maintenance procedure.

Note: Instrument settings cannot be changed while in the Fault
state.
The instrument enters the Fault state when a critical error occurs, and the
fluidics system is stopped.
