Connection X4 - voltage/current output (LES 36…/VC6)
Note!
Connection X4
analog output
is assigned only on the LES 36/VC6, LES 36HI/VC6.
Analog outputs 1-10V (voltage) and 4-20mA (current) may only be used alternately; the selec-
tion is made with
LESsoft
in the
Analog Output
tab.
Connection of the analog output is made via the 5-pin, M12-socket X4.
Attention!
When connecting the analog output, note the permissible load resistance:
• Voltage output 1 … 10VDC:

Characteristic curve of analog output
Behavior of the analog output
The LES is equipped with an analog output with linear response within the respective
measurement range. There is a departure from linearity above and below the linear area. In
spite of this, values above the maximum (> 20mA or > 10V) or below the minimum (< 4mA
or < 1V) specified for the measurement range can still clearly be seen for the output values.
The analog output can be conveniently configured with LESsoft. To obtain the most exact
resolution possible, the range of the analog output should be set as small as the application
will permit (the minimum adjustment range is 10mm). The characteristic output curve can be
configured as rising or falling. For this purpose, both distance values
Position Min. Val.
and
Position Max. Val.
for the minimum and maximum analog output value are set
