Fig. 164: Connection of active-type sensors (voltage) with no electrically isolated power supply
1 1 analog sensor requires 1 channel
2 Power supply not electrically isolated
3 The connection between the minus pole of the sensor and ZP has to be performed
4 Long cable
NOTICE!
Risk of faulty measurements!
The negative pole/earthing potential at the sensors must not have too large a
potential difference with respect to ZP (max. ± 1 V within the full signal range).
Make sure that the potential difference never exceeds ± 1 V.
Voltage 0...10 V 1 channel used
Voltage -10 V...+10 V *) 1 channel used
*) if the sensor can provide this signal range
The measuring ranges are described in the section Measuring Ranges
Ä Chapter 1.7.3.1.7
“Parameterization” on page 842 Ä Chapter 1.7.3.1.10 “Measuring Ranges” on page 851.
In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
