203 The selected system bus
module does not exist.
x x Check plug connections and terminating resistors on the
system bus.
208 The system bus was not able
to transfer data into the
database.
x x The system bus module software version is not compatible
with that of the system controller; update the system
controller software.
209 The system bus connection to
this module is interrupted.
x x Check the system bus connection to the indicated module.
Check the power supply system of the indicated system
bus module.
210 The system bus module
configuration has changed.
x x For information; the configuration data are automatically
updated
211 The system bus module has
no more on-board memory.
x x Check the system bus module configuration:

Analyzer Modules
300 No new measurement values
from analog/digital converter.
x x Notify service.
301 Measurement value exceeds
the analog/digital converter
value range.
x x Check sample gas concentration. Notify service.
302 Offset drift exceeds half the
permissible range.
x
303 Offset drift exceeds
permissible range.
x x
Check analyzer module and sample preparation.
Permissible range: 150% of smallest installed measurement
range; 50% of physical measurement range for Uras26.
Notify service when drift exceeds these values.
304 Amplification drift exceeds
half the permissible range.
x
305 Amplification drift exceeds
permissible range.
x x
Check analyzer module and sample preparation.
Permissible range: 50% of detector sensitivity.
Notify service when drift exceeds these values.
306 The offset drift between two
calibrations exceeds the
permissible range.
x
307 The amplification drift
between two calibrations
exceeds the permissible
range.
x
These messages are generated by automatic calibration.
Check calibration for plausibility. Fix possible cause of
implausibility. Perform manual zero (no. 306) or end point
(no. 307) calibration on indicated detector. Permissible
range: 15% of smallest installed measurement range; for
measurements in facilities requiring authorization and per
27th and 30th BlmSchV, 6% of smallest installed measure-
ment range.
