The fault status signal is also written to a separate document (publication no. DLT7201).
Restarts
For some faults automatic restarts can be configured in the CMS. In this context, it is important
to ensure that the set restarts comply with the normative and safety-related requirements of
the system.

097 Short circuit in potentiometer 1
Plausibility test of potentiometer 1 during operation:
Short circuit between potentiometer reference and
ground.
Potentiometer no. 0 R = 0
Reset
098 Failure in potentiometer 1: Reference voltage or ref-
erence current
Plausibility test of potentiometer 1 during operation:
Fault in reference voltage or potentiometer current
Reference voltage Potentiometer
current R = 0
Reset
099 Failure in potentiometer 2 reference current or refer-
ence voltage
Plausibility test of potentiometer 2 during operation:
Fault in reference voltage or potentiometer current
Reference voltage Potentiometer
current R = 0
Reset
100 Invalid potentiometer configuration
The potentiometer plausibility check at Power ON
detected an invalid configuration.
Problem:
– Reference voltage is missing
– Current in potentiometer without reference voltage
– Variant with redundancy but only one
potentiometer is connected
