Note!
The “failure contact” is activated by system errors and defects (error codes 1 -
23) which would cause instrument failure.
Current outputs 1 and 2 output the defined error current (see chapter 7.2.1).
The failure contact is an obligatory part of all instrument configurations.
If configured, the “maintenance required” contact signals the instrument or
process faults which permit operation to continue but make it necessary to
check the measuring system.
Error codes 30 to 52 or 30 to 78 will cause maintenance required to be
signalled according to the configuration described in 7.1.4.
The “function check” contact is activated in the hold state and when the
instrument configuration is changed (e.g. during calibration).
