Hinweis:
The »fault contact« is active in case
of system faults and defects
(error codes 1 to 23) which can
cause the instrument to fail.
The preset error current is output at
current outputs 1 and 2
(see Chapter 7.2.1).
The fault contact is defaulted for all
settings.
The »maintenance contact«, if
configured, signals faults in the
instrument or process.
Operation can continue but the
measuring system will then require
an inspection.
