5.1 ID switch
This switch is used to set the module ID and can be set from 0 to 9. The default setting is 0.
5.2 Reset switch
To reset the module to factory settings do the following:
•
Change ID Switch to position 0
•
Switch OFF the power for the module
•
Press the reset button and keep it pressed
•
Switch on the power for the module
•
Keep the reset button pressed until all LEDs on the module are illuminated
•
Release the reset button
•
Switch the power OFF and wait 5 seconds
•
Switch on the power and wait until the green power LED is on
5.3 Digital output
The DLS-C(H)/FLS-C(H) contain two digital outputs for level monitoring (DO 1 and DO 2) and one digital
output for error signalization (DO E). These outputs are open drain outputs as shown in figure 7 and
can drive up to 200mA. Maximum switching voltage is 30V DC. In the ON state, the FET transistor is
electro conductive.
5.4 Digital Input
The Digital Output (DO 1) can be configured as a Digital Input (DI 1). This is useful for triggering measurements by means of an external
switch or push button. Please refer to chapter
8.4 Digital Input on page 30

5.5 Analog output
The analog output of the DLS-C(H)/FLS-C(H) is a current source (0..20mA or 4..20mA). It is capable of driving loads up to 500

The stated errors include all possible errors as Temperature drift, linearity, surface color and measurement distance.
The best accuracy of ±1.5 mm for the DLS-C(H) 15 and ±1 mm for the FLS-C(H) 10 can only be
achieved by using the digital interfaces (RS-232, RS-422 or SSI)
