Analog voltage inputs M12 and meaning of the LEDs

1-channel precise load cell analysis
The analog input enables direct connection of a resistor bridge or load cell in a 4-wire connection technology.
Fig. 38: Analog volatge input M12, resistor bridge
The shield must be connected to pin 5 of the M12 connector.
You can find an example for the parallel connection of strain gauges here [} 15].
The voltage U is 10 V and is supplied by the EP3356-0022.
ref
Do not earth the cable screen of the sensor on the sensor side
If a shielded sensor cable is used, it should be not grounded on the sensor side. Otherwise it may
come in certain system configurations to error of measurement.
