Error messages in "Malfunction" status

Malfunction
operating condition
Error code Meaning and cause
3 MEMORY ALLOC FAILURE
The internal measured value memory is
full.
8 ERROR INITIALIZING RX UNIT
Data transmission between the transmit-
ter unit and receiver unit is disrupted.
9 SYSTEM IS UNCONFIGURED
The analyzer is not fully configured.
10 SETTINGS IS CORRUPTED
The analyzer is not configured correctly.
11 SETTINGS OUT OF BOUNDS
The configuration contains parameters
that are outside the permitted value rang-
es.
13 TEMP REG. TIMEOUT
The temperature in the transmitter unit or
in the receiver unit may be too high be-
cause the temperature regulation failed.
14 BEAM BLOCK
The laser beam does not reach the receiver
unit.
110
The analyzer goes into the "Malfunction" operating condition if an error oc-
curs during initialization of the analyzer. Since the analyzer runs through the
initialization routine several times, it can take up to five minutes until the
analyzer switches to the "Malfunction" operating condition.
The analyzer goes into the "Malfunction" operating condition if an error oc-
curs in the "Measuring" operating condition and an initialization has therefore
been launched.
The analyzer can quit the "Malfunction" operating condition only if the error
has been eliminated (see following table), and is no longer pending during the
subsequent initialization.

How to resolve the error
 Shut down the analyzer.
 Restart the analyzer.
 Check and repair the electrical connec-
tion between the transmitter unit and
receiver unit.
 Configure the analyzer using the device
software.
 Correct the configuration of the ana-
lyzer using the device software.
 Correct the configuration of the ana-
lyzer using the device software.
 Cool the unit using one of the following
methods:
 Shielding from the heat source
 Improving the air circulation
 Clean all optical components through
which the laser beam passes
 Remove any foreign matter that may be
present and that may interrupt the
transmission of the laser beam
 Check and correct the alignment of the
transmitter unit in relation to the re-
ceiver unit
