358 Lamp intensity above or below
middle of permissible range.
x Lamp intensity has fallen to 10% of Init value. Check the
intensity values in the
Diagnostics /Test
→
Module
specific → Lamp Intensity
menu. If all four values
have fallen by about the same amount compared to the
Init values, the cause is reduced lamp intensity. The lamp
should be soon replaced (see page 307). If only the two
measurement detector values have dropped, the cause
is probably a contaminated sample cell. Clean the sam-
ple cell (see page 294) or exchange it.
359 Lamp intensity above or below
permissible range.
x x Lamp intensity has fallen to 5% of Init value. Check the
intensity values in the Diagnostics /Test → Module
specific → Lamp Intensity
menu. If all four values
have fallen by about the same amount compared to the
Init values, the cause is reduced lamp intensity. Replace
the lamp (see page 307) and perform an amplification
optimization (see page 310).

370 Beam transmission too low x The beam transmission has fallen below the limit value
for reliable measurements. This indicates improper
alignment of the optical units or contamination of the
optical windows. Clean optical windows and check
alignment.
371 The temperature input signal
exceeds the permissible range.
x The gas temperature is outside the permissible range
for temperature equalization. The accuracy of the meas-
ured gas concentration could have been reduced. If the
supplied values are correct, the device is operating out-
side the specifications.
372 The pressure input signal ex-
ceeds the permissible range.
x The gas pressure is outside the permissible pressure
equalization range. The accuracy of the measured gas
concentration could have been reduced. If the supplied
values are correct, the device is operating outside the
specifications.
