An actuator with separate supply is
connected to the external 24 V via the
terminals O+ and O-� The signal can be
taken from the terminals C1���C4 and 0 V�
1: Analogue module
2: Actuator with separate supply
6.2.4 Electrical connection 0 V terminal
►
Do not connect the 0 V terminals (analogue output 0 V) of the respective
channels of the current output modules to each other�
> This connection leads to faulty current signals�
The connection of the 0 V terminals (analogue output 0 V) results in a
parallel connection of the resistances R1 and R2 (see drawing)� This leads
to faulty current signals�
Example
This problem can occur when a frequency converter is connected, i�e� the
connection of the 0 V terminal is established there (common-)�
►
Adhere to the documentation of the frequency converter�
