59
Both sensor elements faulty.
61
Interruption measuring element 2
(Pt 1000).
62
Short circuit measuring element 2
(Pt 1000).
71
Detected sensor drift
exceeds warning level.
72
Detected sensor drift
exceeds alarm level.
91
Supply voltage outside the
operating voltage range.
92
Operating temperature of the
electronics outside the specified
range.
• Diagnostic states of the diagnostic output (
DA
)
-
N
: Nominal operation, no faults detected.
-
W
: Warning: Anomaly detected, operation with reduced 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 dOU1 (see page 27).
-
X
: Undetermined (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 FOU2).
As soon as no reliable temperature measurement is possible any more,
a signal which corresponds to the fault state is provided in any case.
-
X
: Undetermined (a defined reaction of the output cannot be guaranteed
in case of a fault).
