Diagnosis levels
The detector monitors its operation largely autonomously. The signals of all
sensors are permanently monitored. In particular, the temperature sensors, light
emitters, and light receivers are monitored to ensure that they are functioning
correctly. Signal processing takes account of the monitoring results and adapts its
behavior accordingly.
The following diagnosis levels are derived from the different control measurements:
Normal
l
Observe information
l
Replacement recommended
l
Replacement necessary
l
Fault
l
When an error occurs which impairs the correct functionality of the detector, a fault
message is reported to the control panel. To correct the cause of the fault,
additional information is available in the detector. The diagnosis levels can be read
out using the FXS2061 SWING tool. You will find more information in
document A6V10227643.
