11 Notes on parameter setting via IO-Link
On delivery the LT30xx-type unit is not operational.
First, the integrated overfill prevention OP has to be adjusted.
Depending on the application, OP adjustment can be carried out in differ-
ent ways:
• directly on the display
.
• via an IO-Link tool (e.g. LR DEVICE), button "Teach_OP [cOP]".
• via the controller: write the value 208 to the IO-Link index 2
(length: 1 byte).
The OP adjustment is not part of the data storage.
Therefore, a simple replacement (e.g. in case of a unit failure) is only possible with
reservations: On the new unit, the OP adjustment has to be carried out manually,
either via the operating keys or via IO-Link. Only when the OP adjustment has
been carried out successfully does the unit revert to the cyclical process data
transmission.
After a factory reset (button "Restore Factory Settings"), the device reboots
and the factory settings are restored.
12 Operation
After switch-on of the operating voltage, the unit is in the operating mode
(= normal operating mode). It carries out its measurement and evaluation
functions and generates output signals according to the set parameters.

Check whether the unit operates correctly.
