4.11.4 Error 128, Path Length Error

This error occurs when the movable cell in the Cell Body is not able to move or when
the right path length was not archived during a certain time (time out).

Enter the Service Menu, go to Manual tests/ Measuring Unit/ Position settings. Enter
6 mm path length and press "SET". If you by doing this still was not able to move the
Cell and received Error 128 the following things have to be checked:

•

Check for dust between the Cell walls and the Cell House.

•

Did you hear any noise like the Motor tried to move the Cell House? If you did,
it indicates that the Motor received power. If not, check for mechanical obstruc-
tions.

4.11.5 Error 512, Speckle Function Error

Every time the Variable Cell is instructed to move, the firm ware in the Measuring
Unit Board's EEPROM, checks for an empty Cell. If the Cell is not empty, Error 32
will be displayed. In this case the firm ware will try to move the Cell. If that fails
within a certain time limit, Error 128 will be displayed. After a new Path Length is
set, the intensity of light on the Speckle Emitters is adjusted. Different Path Lengths
demand different intensity levels to ensure that the Detector Gain is not too high. If
this adjustment is not possible, Error 512 will be displayed.

4.11.6 Error 16384, Strain Gauge Failure (Load Cell)

This error could mean two different things. It could be a defect Load Cell usually
caused by mechanical obstruction. The most common case seen where the Load Cell
has been defect is when you install the TWM on the instrument by assembling the
instrument on top of the Test Weight and by doing this you place the instrument on
top of the Test Weight Balance. According to the instruction the instrument should
be positioned on the side before assembling the Test Weight Module. See User
Manual for Infratec 1241 Modules, p/n 60043623

The other and second most common reason for this error is vibrations The instrument
should be placed on a stable work space. Before the analyse starts the empty weight
is measured and when the Sample Cuvette is full the full weight is measured. During
these measurements the instrument has to be free from vibrations.

Also banging on the instrument keypad during the empty weight measurement can
be dangerous.

4.11.7 Error 32768, Hardware Error

This error can occur whenever there is a problem with any of the modules in the in-
strument. To be able to find out more about the problem, enter the Service Menu, go
to Quality Control/ Hardware Log. By doing this the error log is displayed. The log
is presented by date in Hex Code. Mark the actual error by using the arrow key and
press enter.

By doing this the error will be translated and presented together with the command
that was sent out from the DSP when the error occurred.

By using the function "Export logs & configuration" you are able to get the hardware
log on a diskette. This could be useful when you are not present and want to know
where the problem might be before you make your service visit.

Export logs & configuration can be done from the User Menu and the operator can
send the log files by e-mail to you. These files will only be presented in Hex Code
and you will need the HL Translator to be able to read the error as text. The HL
Translator can be downloaded from the FOSS Intranet/Internal Knowledge.
