Filter

The analogue signal can be smoothed with the low-pass filter. Smoothing also changes the rise and
fall time. Filtering only affects the analogue output. The filter time corresponds to the time constant ô
of a low-pass filter. If there is a sudden change in flow, the system reacts with a delay. According to
the set time constant ô the signal at the output of the filter has risen to 63.2% of the end value.
5.2.6

Replicating parameters

This function enables all settings that have been carried out on one sensor (master) to be transferred
to other identical sensors (device).
Parameters are transferred with the IO-Link functions. The previously configured sensor (master) is set
to a master mode, which enables it to transfer its parameters to an identical device (same device ID).
5.2.7

Minimum/maximum value

The minimum values and the maximum values for the flow measurement are displayed and reset in
the SHOW mode.
Switching off the operating voltage resets the minimum and maximum values.
5.2.8

Security code

The settings can be protected from unauthorised access by setting a numerical code of up to 4 digits
è 8.12 Setting security code (EDIT mode). The security code must be entered every time a setting is
changed (EDIT mode and TEACH mode).
5.2.9

Graphic distance monitoring

Function of the bar graph in RUN mode
The "distance" input variable is assigned to the two bar graphs. The bar graphs show the current posi-
tion of the object proportional to the value of the relevant switching point.
– Object outside the sensing range: all segments lit (maximum distance).
– Object approaches the switching point: the red segments switch off one after the other.
– Object has reached the switching point: all red segments are switched off, all green segments are
on.
– Object approaches the measuring nozzle: the green segments switch off one after the other.
