Operation Liquipoint FTW33
26 Hauser
IO-Link communication
• Commissioning with factory settings: The device is configured for use with water-based
media. The device can be commissioned directly when used with water-based media.
Factory setting: Output 1 and output 2 are configured for XOR operation.
• Commissioning with customer-specific settings: The device can be configured differently
to the factory settings via IO-Link. Select User in the Active switchpoints parameter.
• Each change must be confirmed with Enter to ensure that the value is accepted.
• Incorrect switching is suppressed by adjusting the settings in the switching delay/
switchback delay (Switching delay time/Switchback delay time parameters).
11 Operation
11.1 Customer-specific IO-Link settings
11.1.1 Hysteresis function, level detection
Wet calibration (required only for non-conductive media)
1. Navigate to the Application menu level
 Configuration: Parameter → Application → Active switchpoints = User
2. Immerse the device in the medium to be detected
3. Adopt the
ε
r
of the process medium present.
 Configuration: Parameter → Application → User Calibration → Get Calibration
1/2
The switch limits can be adjusted accordingly
11.2 Advanced settings
11.2.1 Process fluid
For reliable point level detection, the device can be adapted to the process conditions in
question.
The following settings can be made via IO-Link:
Parameter → Application → Active
switchpoints
• Standard preconfigured for:
Water- or alcohol-based media (ε
r
≥ 10)
For example, water, milk and various dairy products, soft drinks, beer
• Extended preconfigured for:
Oil-based media (ε
r
> 2.4)
For example: Oils, ketchup, mustard, mayonnaise, honey, nougat spread
• User ; can be freely configured to customer medium:
– Switch point value Output 1/2
– Switchback point value Output 1/2
– ε
r
For dielectric constants (DC values) of many media commonly used in various
industries refer to:
