Operation
MSC7401 / 7802 / 7602 Miniature sensor controller for inductive displacement sensors
5.3.1
Automatic Sensor Recognition
The first menu item is the automatic sensor recognition.
LED D2 = red
The automatic sensor recognition checks the connected sensor and determines the parameters for the com-
mon MICRO-EPSILON sensors:
- Sensor type (half bridge or full bridge (LVDT))
- Supply frequency and
- Excitation voltage
After the automatic sensor recognition has been completed, the LEDs confirm the status.
D3/D4 =
green
Sensor recognition successful
After successful recognition, the system is ready for
use. The output signal is preset according to the
factory setting, as well as a rough adjustment of the
measuring signal.
D3/D4 = red
Automatic recognition is not suc-
cessful
The parameters must now be set manually according
to the respective instruction manuals of the sensor
used. An automatic jump to the menu item
Sensor
parameter
is done
.
5.3.2
Signal
LED D2 = orange
This function allows you to adjust the type of output signal, e.g., 2 ... 10 V or 4 ... 20 mA.
Automatic recognition is available. For a load at the output of:
> 1 kOhm, voltage output 2 ... 10 V is set,
< 1 kOhm, current output 4 ... 20 mA is set.
