2.3 Status outputs B1 and B2
•
The status outputs are galvanically isolated from the current output and all input circuits.
•
Setting data and functions can note down in Section 3.3.
Please also refer to Sect. 3.2 Factory settings.
•
Typical status outputs B1 and/or B2
B1/B2 status outputs B1/B2
B
⊥
chassis ground,
binary outputs and inputs
•
All operating data and functions can be set,
see Sect. 4 and 5.9, Fct 1.07 and/or 1.08 for operator control
The status outputs can be operated in the active or passive mode.
Active mode:
The current output is the internal voltage source.
Passive mode: External DC or AC voltage source required.
Characteristics of the status outputs Switch open Switch closed
OFF (switched off) no function
ON (e.g. operation indicator) Power supply OFF Power supply ON
SIGN I (F/R mode) Forward flow Reverse flow
SIGN P (F/R mode) Forward flow Reverse flow
TRIP POINT (limit switch) inactive active
AUTO RANGE (automatic range
change) high range low range
OVERFLOW I (I overranged) current output OK current output overranged
OVERFLOW. P (P overranged) pulse output OK pulse output overranged
SMU I (low-flow cutoff active) Inactive active
SMU P (low-flow cutoff active) Inactive active
Inverse B1 (switches B2 inversely to B1) B2 open, B1 closed B2 closed, B1 open
ALL. ERROR (all errors) errors no error
FATAL.ERROR (fatal errors only) errors no error
EMPTY PIPE (option) when measuring tube is empty when measuring tube is full
