Alarm
POWER FAILURE
Running re-started
automatically or is
suspended. Check status.
POWER FAILURE: ***** rpm
Door is closed. Refer to
manual for further detail.
E11-E64
Note If a "SET ROTOR" alarm message appears, this micro-ultracentrifuge does not accept the
CE or VACUUM button for 20 minutes to ensure safety. Wait at least 20 minutes, then press the
CE button.
If any alarm message between E11 and E64 appears, this micro-ultracentrifuge requires maintenance
by a service representative. When ordering a repair, inform us of the alarm code you have received.
Note 13 is an alarm code that indicates a failure of the speed detector.
If this alarm code appears, this machine does not accept the CE or VACUUM button for 120
minutes to ensure safety.
These 120 minutes are required for the rotor to stop.
Wait at least 120 minutes before pressing the CE button.
(This "120 minutes" is the time which passed after a power failure occurs.)

User-corrected problem

Some problems are not identified and reported by the self-diagnostic capability of the
micro-ultracentrifuge.
To correct these problems, take the action(s) described in the table below.
4-4 Sorvall MTX 150
Cause
1. A power failure occurred while the
rotor was rotating.
Refer also to "Emergency recovery from power failure"
1. A power failure occurred while the rotor
was rotating and the speed could not be
detected after power returned.
(This alarm code appears when the detector
of this micro-ultracentrifuge could not
identify which status (status 1 or status 2)
occurred.
Status 1: The rotor stopped normally.
Status 2: Although the rotor continued to
rotate, the speed of the rotor was not
detected due to a failure of the speed
detector.
If this alarm code appears, this
micro-ultracentrifuge does not accept the CE
or VACUUM button for 120 minutes to ensure
safety (The same thing can be said of "E13").
Refer also to "Emergency recovery from power failure"
Refer to NOTE.
Action
Unless the set run time has elapsed, restart
the run.
If the instrument was automatically
restored and the rotor is rotating at set
speed, then let the run continue.

• This micro-ultracentrifuge does not accept
the CE or VACUUM button for 120 minutes from
power failure.
If you are convinced that the rotor has come to a
complete stop, press the SPEED column,
HOLD , 9 , 0 , 1 , HOLD and Enter button in order
when the Run screen is displayed. Then press
the VACUUM button. This micro-ultracentrifuge
accepts the VACUUM button.
First open the door a little to confirm that rotor
has come to a complete stop.
Then open the door properly.
