4.6 Measured value damping (dAP)
The damping time allows to set after how many seconds the output signal has
reached 63 % of the final value if the flow value changes suddenly� The set damp-
ing time stabilises the outputs, the display and the process value transfer via the
IO-Link interface� The signals [UL] and [OL] (→ 12 Troubleshooting) are defined
under consideration of the damping time�
4.7 Low flow cut-off (LFC)
With the function Low Flow cut-off small volumetric flow quantities can be ignored
(→ 10.4.10)� Flows below the LFC value are evaluated by the sensor as standstill
(Q = 0)�
4.8 Simulation
With this function flow and temperature values can be simulated� (→ 10.5.3)� The
outputs operate as previously set�
4.9 IO-Link
This unit has an IO-Link communication interface�
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
necessary information about the required IO-Link hardware and software can be
found at www�ifm�com�
► The memory plug (E30398) must not remain connected to the unit,
because it falsifies the analogue output� It must only be connected for
parameter setting�
