5.2.3 Probes for different tank heights
• The unit can be installed in tanks of different sizes� Probes in different lengths
are available� To adapt to the tank height, each probe can be shortened� The
minimum probe length is 100 mm, the maximum probe length is 1600 mm�
• Probe and housing can be rotated without restriction� This enables easy
installation and orientation of the head of the unit after installation�
5.2.4 Defined state in case of a fault
• If a fault is detected or if the signal quality is below a minimum value, the
analogue output passes into a defined state� For this case, the response of the
output can be set via the parameter [FOU2]�
• Temporary loss of signal caused e�g� by turbulence or foam formation can
be suppressed by a delay time (→ 9.1 [dFo])� During the delay time the last
measured value is frozen� If the measured signal is received again in sufficient
strength within the delay time, the unit continues to work in normal operation� If,
however, it is not received again in sufficient strength within the delay time, the
output passes into the defined state�
5.2.5 IO-Link
General information
This unit has an IO-Link communication interface which requires an IO-Link-
capable module (IO-Link master) for operation�
The IO-Link interface enables direct access to the process and diagnostic data
and provides the possibility to set the parameters of the unit during operation� In
addition communication is possible via a point-to-point connection with a USB
adapter cable�
