• Diagnostic states of the diagnostic output (DA)
-N: nominal operation, no faults detected�
-W: warning: anomaly detected, operation with restricted accuracy or functionality possible�
-A: alarm: fault detected, reliable operation not possible any more� The output signal of the
diagnostic output depends on the setting of the parameter dOU�
-
X: undefined (a defined reaction of the output cannot be guaranteed in case of a fault).
• Signals of the analogue output (AA)
-T: temperature-proportional current signal�
-T/B: temperature-proportional current signal during backup operation�
-
F: fault value (defined by parameter FOU). As soon as no reliable temperature measure
-
ment is possible any more, a fault level is provided in all cases�
-
X: undefined (a defined reaction of the output cannot be guaranteed in case of a fault).
