Negative level
[Equal to zero] = negative levels (below the
zero point) are not displayed.
[Permitted] = negative levels are displayed.
If the tank offset is > 0, the level value can be
negative. This parameter defines whether nega-
tive levels are displayed or whether they should
equal zero.
With the option [Permitted], even false echoes in
the area of the (positive) tank offset are detected
that affect the measurement and lead to meas-
urement errors. With the option [Equal to zero],
these false echoes can be suppressed.
The set value is not part of the data storage. It is
not stored in the master.
P-n
[PnP] = positive switching
[nPn] = negative switching
Output polarity for the switching outputs.
ou1
[SSC1] = configures OUT1 as switching
output. OUT1 is assigned to SSC1 (switch-
ing channel 1).
[OFF] = output OFF (high impedance)*
Output configuration for OUT1.
*) This does not affect IO-Link communication.
ou2
[I] = configures OUT2 as analogue output
4...20 mA.
[SSC2] = configures OUT2 as a switching
output. OUT2 is assigned to SSC2 (switch-
ing channel 2).
[OFF] = output OFF (high impedance)
Output configuration for OUT2.
