Condition
Reaction
1 Volumetric flow quantity Q reaches LFC
dST starts, output becomes active
2 dST elapsed, Q reached good range
Output remains active
3 Q above SP (leaves good range)
Output is reset
4 Q again below SP
Output becomes active again
5 Q below rP (leaves good range)
Output is reset again
6 Q reaches again LFC
dST starts, output becomes active
7 dST elapsed, Q has not reached good
range
Output is reset
8 Q reaches good range
Output becomes active
4.10 Low flow cut-off (LFC)
With this function small volumetric flow quantities can be suppressed
Flows below the LFC value are evaluated by the sensor as standstill (Q = 0)�
4.11 Simulation
With this function flow and temperature values can be simulated
The simulation does not have any effect on the totaliser or the current flow� The
outputs operate as previously set�
When the simulation starts, the value of the totaliser is saved and then the
simulated totaliser is set to 0� The simulated flow value then has an effect on the
simulated totaliser� When the simulation is finished, the original totaliser value is
restored�
During the simulation the original totaliser value remains saved without any
changes even if there is a real flow�
4.12 IO-Link
This unit has an IO-Link communication interface which enables direct access to
process and diagnostic data� In addition it is possible to set the parameters of the
unit during operation� Operation of the unit via IO-Link interface requires an IO-
Link capable module (IO-Link master)�
With a PC, suitable IO-Link software and an IO-Link adapter cable communication
is possible when the system is not in operation�
The IODDs necessary for the configuration of the unit, detailed information about
process data structure, diagnostic information, parameter addresses and the
