315 No new measured values from
the analog/digital converter.
x Notify Service.
316 The measured value exceeds
the range of the analog/digital
converter.
x Notify Service.
317 A computational error occurred
during calculation of the meas-
urement value.

Caldos, Magnos
319 The measurement bridge is
improperly balanced.
x x Notify Service.
320 The measurement amplifier
offset is too high.
x x Notify Service.
MultiFID, Fidas
321 The detector temperature is
below the lowest temperature
permissible.
x x Status message during warm-up phase. If the status
message appears after warm-up phase: Check the ther-
mal link and replace if necessary.
322 The flame is out. x x Status message during warm-up phase. If the status
message appears after warm-up phase: Check gas sup-
ply, heater plug
323 The analyzer is in the
fail-safe state.
x x Causes: Flame temperature > detector set point +
200 °C, hardware fault, Pt-100 line break or short circuit.
Switch power supply off and back on after ≥ 3 seconds.
If this status message appears again, notify Service.
Remark: Fail-safe-state means: Heater off, combustion
gas valve closed, instrument air valve closed, case purging
on, zero-gas valve open.
Temperature regulator
324 Temperature is above or below
upper and/or lower limit value
1.
x Status messages during the warm-up phase.
If the Status messages appear following the warm-up
phase: Check whether the permissible ambient temper-
ature range (see page 332) is being maintained. Check
the analyzer module thermal link and replace if neces-
sary.
Fidas24: The temperatures of the detector (T-Re.D) and
if applicable, the heated sample gas connection
(T-Re.E) are outside the limit values.
325 Temperature is above or below
upper and/or lower limit value
