Sys. - Positive Zero
Return
AUTO - OOS
Use this parameter to interrupt evaluation of measured variables. This is
necessary when a piping system is being cleaned, for example. This setting
acts on all parameter and calculations of the measuring device.
Options:
OFF (signal output not interrupted)
ON (signal output is set to the value for "Positive zero return" or "Zero
flow")
Factory setting:
OFF
!
Note!
• If positive zero return is active, a flow value of "0" is output via the
output value OUT (AI Block).
• Active positive zero return is relayed to downstream function blocks or
higher-order process control systems by means of the status
UNCERTAIN of the output value OUT (AI Block).
• Positive zero return can also be controlled using cyclic data transfer via
the Discrete Output function block.
Sys. - Special Filter
AUTO - OOS
There is the option of activating two signal filters in this parameter. These
filters make it possible to either suppress the signal caused by severely
fluctuating flows (STANDARD option) or to reproduce it completely –
both on the display and on the FOUNDATION Fieldbus output
(DYNAMIC FLOW option).
Options:
STANDARD
For signal output with normal, stable flow.
DYNAMIC FLOW
For signal output with severely fluctuating or pulsating flow.
Factory setting:
STANDARD
"
Caution!
• The signal behavior on the outputs also depends on the
"Sys. - Flow Damping" parameter.
• Additional filter settings (e.g. STANDARD CIP or DYNAMIC FLOW
CIP) can only be selected using a special service code. Such settings
that are mostly made by a service technician are deleted again if the
customer code is entered anew and can then no longer be activated.
Sys. - CIP Samples
AUTO - OOS
This parameter is only used in the event of a service call.
Sys. - Permanent
Storage
read only
This parameter indicates whether permanent saving of all parameters in
the EEPROM is switched on or off.
