Infratec™ 1241 Grain Analyzer
Service Manual 1001 5015 / Rev. 4 4:33
4.11.1 Error 4, Grating Motor Error
This error indicates that the Monochromator Grating is not able to move.
Enter the Service Menu, go to Manual tests/ Monochromator and try to manually
start the Grating Motor by setting it to On/Off. If the error occur again while doing
this, open the left side Door and observe the LED marked "DIR". A flashing light
indicates that the Grating is moving, a continuous light the opposite. Check the con-
nections on the DSP Board and on the Monochromator. If this did not solve the
problem the Monochromator has to be replaced.
4.11.2 Error 22, MU/TWM Data Range Error
This is an error that may appear if a command was sent with data outside the valid
range. For example if the Variable Cell was instructed to move to 4 mm, then an error
22 will be given, as the lowest accepted value is 5 mm. (invalid data received).
4.11.3 Error 32, Speckle Signal Blocked
This error indicates that there are still sample in the Cell. When the error occurs the
user will get an instruction to clean the Sample Cell by using the command "Flush
cell". If the problem is not solved by this the Speckle function is faulty.
Enter the Service Menu, go to Manual tests/ Measuring Unit/ Sensors. When the
Sample Cell is empty the Speckle Sensors should indicate 1 1 1 1. If this is not indi-
cated use a flash light to light up the inside of the Sample Cell.
If this causes 1 1 1 1 to be displayed then there is a fault with the Speckle Emitter
Board and it will need to be replaced.
If you do not receive this response, then the Speckle Detector Board is faulty. This
board is located inside the Cell House. If this is the case, then you need to replace the
Measuring Unit, see spare parts manual for part number.
4243 0x1093 No cup detected. The speckle function is not
used. The cup is detected by
the difference in absorbance
between the reference scan and
the first sub-sample. Due to
that, it is not possible to run a
scan with an empty cup.
4244 0x1094 Extended range not allowed.
4245 0x1095 Unknown Scan Mode.
4246 0x1096 Sample Transport Module
makes too many steps.
Sample Transport Module tries
to make more than 10 steps.
Balance check failure. Clean
the Test Weight Module. If the
problem persists contact serv-
ice. To analyse without Test
Weight results: Disable Test
Weight on Task Bar. Occurs when the difference be-
tween the tar weight of the
present measurement com-
pared with the previous meas-
urement is higher than the
value stated in the twm.ini file.
Empty Check Limit (Default
100).
