 10 Position of LEDs on housing cover
A Housing cover with M12 plug, plastic
B Housing cover with valve plug
There is no external signaling via LEDs on the metal housing cover (IP69). A connecting cable
with an M12 plug and LED display can be ordered as an accessory if necessary. This cable has
no red LED. See "Accessories".
Position LEDs Description of function
1
Green LED
(gn)
Lit: Measuring device is operational
In conjunction with IO-Link communication:
• lit: SIO mode
• flashing: Active communication, flash frequency
• flashes with increased luminosity: Device search (device identification), flash
frequency
2
Yellow LED
(ye)
M12 plug
LED 2a
Active only in conjunction with IO-Link communication.
LED 2b display of sensor status
Sensor is covered by medium.
M12 plug in conjunction with IO-Link communication:
LED 2a switch status/switch output 2
Following customer adjustment: Sensor is covered by medium 1.
LED 2b switch status/switch output 1
Following customer adjustment: Sensor is covered by medium 2.
Valve plug: Indicates switch status
MAX mode (overfill protection): Sensor is not covered by medium
MIN mode (dry-running protection): Sensor is covered by medium
3
Red LED (rd) Warning/Maintenance required
flashing: Error remediable, e. g. invalid calibration
Fault/device failure
lit: Error not remediable, e. g. Electronics error
Diagnostics and troubleshooting
Device search
IO-Link communication: The Device search parameter is used to uniquely identify the device during
installation.
Sensor check
IO-Link communication: The Sensor check parameter checks if the sensor system is functioning
correctly. The sensor must not be covered and must be free of residue.
Medium calibration
Empty/full calibration are carried out with the test magnet or by means of IO-Link communication.
The threshold is defined automatically following calibration. The thresholds can also be adjusted
manually in the case of IO-Link.
Function test
The test magnet is used to invert the current switch status.
The test magnet is included in the scope of delivery. It is also possible to cancel it →  20.
