External Generator Power Set Point Value (XPD, XPQ)
The generator real power set point value may be regulated via an analog input T{x} [x = 1 to 7] if one of the
analog inputs T{x} [x = 1 to 7] is a 0/4 to 20 mA input. The selection of the analog input is done using the fol-
lowing parameters.
Parameter 78
Power setpoint
external OFF
XPD, XPQ
Power set point value: external input OFF / T{x}
OFF .............. External regulation of the generator real power set point value via
the 0/4 to 20 mA input is disabled. If this parameter is configured to
"OFF" a generator real power set point value is not monitored via
the 0/4 to 20 mA input to the control. The analog inputs can be used
either as a mains interchange (import/export) real power actual value
or as freely configurable alarm inputs. If terminal 5 is utilized, the in-
ternal set point value 2 "Pset2" (Parameter 36) is used as set point
val
ue. The subsequent screens of this function are not displayed.
T{x} .............. External regulation of the generator real power set point value via
the 0/4 to 20 mA input is enabled. If terminal 5 is utilized, the inter-
nal set point value 2 "Pset2" (Parameter 36) is used as the set point
val
ue. The subsequent screens of this function are displayed.
Note
Please note the following if analog input T{x} has been selected:
• "Analog in Pmains" (Parameter 24) in the "Measuring" section must be confi-
gured as OFF.
• "Anal
og input {x} scalable" (Parameter 215) in the "Analog inputs" section must
be confi
gured as OFF.
• The GCP-30 is may be purchased with various types of analog inputs. If the con-
troller being configured has analog inputs, only a 0/4 to 20 mA input may be used
for this input.
• Due to the fact that LeoPC1 is not a dynamic program, the graphic display of the
generator/plant does not automatically update to reflect any changes made during
reconfiguration. To update the program’s graphical display, LeoPC1 must be
shutdown and restarted.
Priority of the functions of the analog inputs
If more than one function has been assigned to an analog input, the following is the
priority that the control assigns to functions:
• Highest priority: Mains interchange real power actual value measurement
• Middle priority: Real power set point value
• Lowest priority: Measuring input as common analog value
