3BSetup and function
4.4 Diagnosis levels
The detector largely auto-monitors its function.
The following diagnosis levels are derived from the different control measurings:
z Normal
z Exchange required
z Fault
Details see table below.
When a fatal error occurs, which makes the proper function of the detector
impossible, a fault message is signalled. To remedy the cause, additional
information is available in the detector. This information may be displayed by e.g.
the detector exchanger and tester FDUD29x (details see Operation Detector
exchanger and tester, doc. nos. 007227 and 009718).

Signification Actions
'No Deviation' Normal, no fault is present
The detector is fully functional
none
'needed excha.' * Exchange required
Button monitoring outside the tolerance
Replace detector
Fault is present
– Alarming is no longer ensured
– Button monitoring outside the tolerance
or impaired by extraneous influences
Replace detector
Supply error
– Check detector line voltage
– Replace detector
Software error (Watchdog error) Replace detector
Storage error
Replace detector
Any fault message
Communication error between detector
and control panel
Remedy cause
Note
The status 'Any fault message' can be displayed together with another status, e.g.
'needed excha.' (exchange required).
* Indication on the detector exchanger and tester always in English; no translation
