Functions and operating modes
4.5.1
Setting options
The devices feature the following three setting options:
n
Setting via IO-Link
n
Setting via the touchpads
n
Setting via FDT/DTM
4.5.2
Normal operation – run mode
The device detects the distance to the surface of the medium and shows the required switching
or analog behavior according to the factory set or customer-specific parameters. The measured
distance to the medium is shown in the display. The selected unit and the status of the existing
switching outputs are indicated via LEDs.
4.5.3
Programming mode
If the sensor is unlocked, the display switches to Programming mode after the [MODE] touch-
pad is pressed. All parameters and their associated values can be read and modified in Pro-
gramming mode. A short press of the [ENTER] touchpad displays the values of a parameter. The
[MODE] and [SET] touchpads are used to navigate in Programming mode.
4.5.4
Output functions – switching output
A window function and a hysteresis function can be set for the switching outputs.
Window function
The window function is used to teach in a switching range in which the switching output takes
on a defined switching state. The switching range is defined by an upper and lower limit value.
The minimum distance between the limit values is 5 mm (LUS211-40…) and 10 mm
(LUS211-130…). If the upper limit value is changed, the lower limit value is automatically adjus-
ted.
