Additional device-specific information On delivery, the unit is not operational! First of all the sensor has to be adjusted to the application / the tank (see
operating instructions). Only carry out the tank adjustment when the unit is installed!
The sensor calculates the level based on the measured capacitances of its individual measuring segments. To ensure
correct calculation the measured capacitances have to be comparable. This means that in some applications
additional grounding may become necessary (see operating instructions, chapter Troubleshooting).
Note! The tank adjustment is not part of the data storage!
After unit replacement, adjustment has to be made again manually via IO-Link. Only when the tank adjustment has
been carried out successfully does the unit revert to the cyclical process data transmission.
Note!
After a factory reset, the factory settings are restored.
The unit is not operational!
Adjustment options (standard commands)
Adjust empty tank: The process value of the unit is adjusted to an empty tank.
"Empty" means the level is below the detection range.
Adjust full tank: The process value of the unit is adjusted to a full tank.
"Full" means the level is above the detection range.
Dynamic tank adjustment: The process value of the unit is adjusted to the level in the measurement range
during the time window (start to stop). During the entire time window, the level has
to be in the measuring range! The dynamic adjustment does not have a timeout and
therefore always has to be stopped or aborted via IO-Link.
For non-changing products, the highest operational reliability is obtained by carrying out empty and full adjustments.
These two adjustments are also recommended for adhering products if they remain unchanged.
Deposits can only be detected when empty and full adjustments have been made!
For changing products (with extremely different dielectric constants) only the adjustment to the empty tank should
be made.
Causes of events
Event Meaning 0x5000 The unit is faulty / has to be replaced. 0x6320 The parameter value is outside the permissible range. Check the data sheet and the values. 0x6321 Adjustment or parameter missing. Make a tank adjustment or check the data sheet. 0x7710 Short-circuit on a switching output. Check the installation. 0x8C40 Deposits in the detection range were detected. Clean the detection range / inner wall of the tank. 0x8CA4 Several levels were found in the detection range. Check the installation and the inside of the tank for bubbles,
voids or deposits. 0x8CC0 The signal strength is too low or to too high. Increase or decrease the sensitivity of the unit (see operating
instructions).
