Temperature Display; Error Recovery Routine - Rautheon UW50PV Manual De Operation

Temperature Display

The temperature display can be prompted to
display in Fahrenheit or Centigrade. See
Prompting the WE-6 in the Programming
section of this manual.
To display temperature, press the Display
Temp key. The display will read "F" or "C"
and the temperature as long as the key is
pressed. The computer will update the
display automatically.

Error Recovery Routine

When the computer detects an error, it will
stop running the current step and display a
message to indicate what type of error
was found:
• "FILL" indicates that the washer-extractor
did not fill within the allotted time.
• "EMTY" indicates that the washer-
extractor did not drain in the allotted time.
• "TEMP" indicates that the temperature
sensor has recognized an over-
temperature-limit condition.
• "MEMR" indicates that the computer
has detected a problem with the cycle
information. The cycle must be edited.
• "WATER" indicates that the WE-6
computer senses low, medium, or high
water level at the end of the stop routine.
All outputs remain off while the message
displays, and the door cannot be unlocked.
Note: The WE-6 computer will not allow
the door to be opened while there is water in
the washer-extractor.
F232050
Each of these errors is considered to be
recoverable. The operator has two minutes to
respond to the error condition (except in the
case of "WATER"). During this time, the
computer will turn the signal (buzzer) relay on
and off at the rate of one second on and one
second off to alert the operator to the error
condition. The washer-extractor may be
restarted by pressing the Enter key. Pressing
the Enter key will restart the cycle step for the
originally programmed time period. The cycle
may be aborted by pressing the Clear key.
After aborting the cycle, the computer will go
to the normal stop routine. If the operator does
not respond to the error condition within the
allocated two minutes, the computer will
automatically abort the cycle.
Note: The "TEMP" alarm can be recovered
only after the temperature falls below the
alarm level.
Certain error conditions are considered to be
non-recoverable:
• If the door opens during a cycle, the
computer will display "DOOR." The
operator must close the door.
Then, after the computer has detected that
the door is closed, it will automatically
abort the cycle and go to the normal
stop routine.
• "OVERHT" will be displayed when the
computer detects an open or shorted
temperature input circuit or temperatures
are outside of the washer-extractor's
allowable limits. Contact a service
technician.
