5.2  Features of the unit
5.2.1  Easy set-up

•  When operating voltage is applied to the unit for the first time, the probe length 

must be entered. The unit is then ready for operation. (→ 10.2). 

•  If necessary, parameters for the output signals and optimisation of the monitor-

ing functions can be set (→ 10.3 to 10.6).

•  All settings can also be carried out before installation of the unit� 
•  Reset to the factory settings is possible�
•  Electronic lock can be set to prevent unintentional operations�

5.2.2  Display functions

The unit displays the current level, either in cm, inch or in percent of the final 

value of the measuring range� Factory setting: inch� The display unit is defined by 

programming (→ 10.3). In the Run mode, it can be temporarily switched between 

length indication (cm / inch) and percentage: 

 

► Press [Set] briefly�  

 

>  The selected unit is displayed for 15 s, the corresponding  LED is lit� With each 

push of the button the display type is changed�

The set unit of measurement and the switching status of the outputs are indicated 

by LEDs�

5.2.3  Switching functions

The unit signals via four switching outputs OUT1���OUT4 that a set limit level has 

been reached or that the level is below the limit value�
For each output the following switching functions can be selected:
•  Hysteresis function / normally open (fig� 5-3): [OUx] = [Hno]�
•  Hysteresis function / normally closed (fig� 5-3): [OUx] = [Hnc]�

First the set point (SPx) is set, then the reset point (rPx) with the requested 

difference�

•  Window function / normally open (fig� 5-4): [OUx] = [Fno]�
•  Window function / normally closed (fig� 5-4): [OUx] = [Fnc]�

The width of the window can be set by means of the difference between 

FHx and FLx� FHx = upper value, FLx = lower value�
