Centrifuges
Terminal Conditions
Terminal Condition messages alert the user to a serious fault
condition. Runs are disallowed or terminated. These conditions
typically cannot be remedied by the user; the centrifuge should
be removed from service until it is repaired by
Thermo
Service.
AIR TEMP SENSOR FAILURE
The chamber air temperature sensor indicated either an
open circuit, or a temperature above 45
°
C. The fault indi-
cates a sensor failure or a refrigeration system problem.
After the rotor stops and the chamber door is opened, note if
the chamber is warm – if so, the rotor may be too hot to
touch. Unplug the centrifuge and contact
Thermo
Service.
(WatchLog Network™ record: incomplete, AIR SENSOR.)
COMPRESSOR FAILURE
While the refrigeration compressor was on, the chamber air
temperature sensor detected an increase of 10
°
C or more
from when the compressor first turned on. The fault indi-
cates a refrigeration system problem. After the rotor stops
and the chamber door is opened, note if the chamber is
warm – if so, the rotor may be too hot to touch. Unplug the
centrifuge and contact
Thermo
Service. (WatchLog Net-
work™ record: incomplete, COMPRESSOR.)
DOOR CLOSED SWITCH FAILURE
A run was in progress when the door closed switch opened,
indicating a circuit failure. Remove all sample from the rotor
after it stops, then unplug the centrifuge and contact
Thermo
Service. (WatchLog Network™ record: incomplete, DOOR.)
DOOR LOCK SWITCH FAILURE
A run was in progress when the door lock switch opened,
indicating a circuit failure. Remove all sample from the rotor
after it stops, then unplug the centrifuge and contact
Thermo
Service. (WatchLog Network™ record: incomplete, DOOR.)
DOOR LOCK SWITCH SHORTED
At run completion, the door lock switch did not open, indi-
cating a circuit failure. The interlock motor is de-energized;
another run will not start. Remove all sample from the rotor,
then unplug the centrifuge and contact
Thermo
Service.
DOOR NOT LOCKED – CONTACT SERVICE
After START was pressed, the door lock switch did not
close, indicating a circuit failure. The run will not start and
the interlock motor is de-energized. Remove all sample from
the rotor, unplug the centrifuge and contact
Thermo
Service.
