Mains (Mains Interchange Import/Export Real Power Actual Value Via Measuring Transducer
[XPD and XPQ])
NOTE
During configuration the free configurable 20 mA inputs can be enabled with the following functions:
• Mains interchange (import/export) real power actual value
• Real power set point value
• Alarm input
Please note the details in the configuration manual 37365.
NOTE
If several controls are interconnected, the 20 mA measuring signal must not be looped through all con-
trols. At each control, a 0/4 to 20 mA buffer amplifier must be connected to the mains interchange (im-
port/export) real power measurement output signal. When selecting the external measuring transducer,
please note that this must transmit both positive and negative ranges when transmitting the supply
and reference power values.
