LI capacitive sensor: Device configuration
The following video and specifications will lead you through the process of oncifugring your LI capacitive sensor
Programming / Quickstart
The sensor comes ready for water applications out of the box. Check the below chart to determine if you need to teach the sensor once installed and follow below guidelines to perform the teach function with software or by using the inductive teach button on the sensor.
| Dielectric constant of common media |
Value (> 1.8 required) |
Teach Required |
|---|---|---|
| Water | ≈ 80 | No; Plug and Play |
| Mineral oil | ≈ 2 | Yes; Empty Teach |
| Glycol | ≈ 37 | Yes; Empty Teach |
| Coolant emulsion | ≈ 25...75 | Recommended; Empty and Full Teach |
QuickStart guidelines using IO-Link / LR Device:
 |
Install sensor and connect E30390 to PC with LR Device software. |
 |
Perform empty teach with fluid level below sensor by clicking "Teach empty state" in LR Device. |
 |
Perform full teach with fluid above active zone (bottom 28 mm or sensor probe) by clicking "Teach full state" in LR Device. |
 |
Sensor is ready for operation with maximum performance. |
QuickStart guidelines using teach button on sensor:
Aqueous (water) Applications:
 |
Install sensor and connect cable. |
 |
Wire outputs and apply power: OUT1: switching output / IO-Link OUT2: switching output |
 |
Sensor is preconfigured for water applications. No further adjustment to sensitivity is required. |
|
Sensor is ready for operation. |
Oil (low dielectric) Applications:
|
Install sensor and connect cable. |
|
Wire outputs and apply power OUT:1 switching output / IO-Link OUT2: switching output |
 |
For oil applications, empty teach is required. |
|
Perform empty teach with fluid level below sensor by following below steps. |
 |
Hold metal object (i.e. screwdriver) on inductive teach button for 10 s (until you see double flash of green power (PWR) LED) to unlock sensor and allow parametrization. |
 |
Remove metal object from inductive teach button. You should see green power (PWR) LED lit continuously. |
 |
Hold the metal object on the teach button until the yellow output (OUT) LEDs flash quickly. |
|
Successful completion of the full adjustment is acknowledged with double flash of the green power (PWR) LED. |
Aqueous applications where buildup or deposits are expected:
|
Install sensor and connect cable. |
|
Wire outputs and apply power: OUT1: switching output / IO-Link OUT2: switching output |
 |
For aqueous applications where buildup or residue is expected a full teach should be carried out for optimal performance. |
|
Perform full teach with fluid above active zone (bottom 28 mm or sensor probe) by following below steps. |
 |
Hold metal object (i.e. screwdriver) on inductive teach button for 10 s until you see double flash of green power (PWR) LED to unlock sensor and allow parametrization. |
|
Remove metal object from inductive teach button. You should see green power (PWR) LED lit continuously. |
 |
After the unit is unlocked, hold the metal object on the teach button for at least 4 s, but not longer than 7 s, until the two yellow output (OUT) LEDs flash quickly. |
|
Successful completion of the full adjustment is acknowledged with double flash of the green LED. |
Using the Inductive Teach Button
The inductive teach button is actuated with a metal object (e.g. a screwdriver 1 x 5.5 mm) by applying it flat to the teach surface. No operation is triggered by actuating the button briefly (less than 1 s) or continuously (longer than 30 s) (static activation)!

Visualization
The sensor comes with three LED lights to signal operating and output status. The following table indicates the LED signalization at factory default. However, the output status of LED1 and LED2 can be freely configured via IO-Link.
- LED1 (yellow) = switching status OUT1
- LED2 (yellow) = switching status OUT1 (OUT2)
- LED3 (green) = operating status
| Operating status | LED1 (yellow) (OUT1) |
LED2 (yellow) (OUT1) |
LED3 (green) (Operating voltage) |
|---|---|---|---|
| Unit ready for operation, no media detected |
OFF | OFF | ON |
| Unit ready for operation, medium detected |
ON | ON | ON |
| No operating voltage / operating voltage too low |
OFF | OFF | OFF |
