Setting an Address
Example for address 5 in Profibus mode:
ADDRESS B
„ „ „ „ „ „
„ „
0 1 2 3 4 5 6 A
Switch position =
„
Mode A
If the mode switch sets A mode, the device operates as an analog device. PROFIBUS may be
used for monitoring and the bus address will be used, which was set previously in bus mode. The
address switches in analog mode define the analog zeroing mode.
Example for setting analog mode and zero mode 3:
ADDRESS B
„ „ „ „ „
„ „ „
0 1 2 3 4 5 6 A
Switch position =
„
Zero Modes
0 Offset Value is always Zero
1
Offset Value (USER_ZERO) stored in the device is not changed.
2 If the valve is off (VALVE_OVERRIDE == FLOW_OFF) for at least 10 sec. an AUTOZERO
is performed.
3 10 sec. after reset, AUTOZERO is performed as long as valve is off. (value stored)
4
10 sec. after reset, AUTOZERO is performed if flow is smaller than 10% of FS. (value
stored)
