u
Set the parameters.
Before parameter setting, familiarise yourself with all the parameters.
u
Check if the unit has accepted the parameter settings. If necessary, read the unit again.
u
Check whether the unit operates correctly.
8.3 Adjustable parameters
Parameters marked with “!” (in the “Access” column) (e.g. [SSC1 Param. SP2]) are only active if
the assigned parameters have been selected.
The abbreviations SSC1 and SSC2 below refer to the switching bits (switching signal channels) in the
IO-Link process data flow. The switching signal channels are assigned to the physical outputs OUT1
and OUT2 via the parameters [ou1] and [ou2].

uni
[m] = metre
[inch] = inch
Selection of the display unit.
Reference height
Setting range: 0.2...15 m
Distance between unit and zero point (
Ò
Fig.
Reference height).
u
Ensure that the reference height
corresponds to the actual tank height.
If necessary, configure a tank offset. (

Fig.
Tank offset)
Tank offset
Setting range: -10...10 m
Distance between the zero point and the tank
bottom (
Ò
Fig. Tank offset).
Upper blind zone
Setting range: 0...10 m
Serves to suppress false echoes, e.g. from noz-
zles
(

Fig. Upper blind zone).
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
(switching signal channel 1).
[OFF] = output OFF (high impedance)*
Output configuration for OUT1.
*) This does not affect the IO-Link communica-
tion.
ou2
[I] = configures OUT2 as switching output
4...20 mA.
[SSC2] = configures OUT2 as switching
output. OUT2 is assigned to SSC2
(switching signal channel 2).
[OFF] = output OFF (high impedance)
Output configuration for OUT2.
dS1
Setting range: 0...60 s
Switch-on delay for SSC1 (switching signal
channel 1).
The switch-on delay reacts according to VD-
MA*
)
.
dr1
Setting range: 0...60 s
Switch-off delay for SSC1 (switching signal
channel 1).
The switch-off delay reacts according to VD-
MA*
)
.
SSC1 Param. SP1
Setting range: 0.005...15 m
Set point 1 for SSC1 (switching signal chan-
nel 1).
Only available if SSC1 is not deactivated.
Set point 1 must be smaller than or equal to the
set tank height [Reference height].
