FOU2
Response of the analogue output in case of a fault
2 settings can be selected:
• FOU2 = ON: The analogue signal goes to the value (21.1 mA).
• FOU2 = OFF: The analogue signal goes to the value (3.5 mA).

Fault in the electronics:
Both sensor elements defective: Analogue signal at fault value
One sensor element defective:
Both drift thresholds (alarm / warning) exceeded:
Analogue signal corresponds to measured temperature.
