Woodward GCP-30 Series Configuration

Manual 37278B GCP-30 Series - Genset Control
Page 28/174 © Woodward
Parameter 35
Analog in Pmains
0-00mA
Package XP, Option T701 only
Analog input P mains: Range 0 to 20 mA / 4 to 20 mA
The measuring range 0 to 20 mA or 4 to 20 mA is selected with this parameter. If
the range selected is 4 to 20 mA and the current is lower than 2 mA, a broken wire
alarm is issued.
Note
It is possible to adjust the display range of the mains interchange (import/export)
real power actual value. Thereto the wanted value must be entered and saved using
the Parameter 244 "name and unit" of the selected analog input (see chapter "Ana-
l
og inputs").
NOTE
For an import/export real power control application, ensure that the set point value selected is in the
middle of the measuring range. This will allow the controller dynamic to be used to its fullest capacity.
Parameter 36
Analog in Pmains
0% 0000kW
Package XP, Option T701 only
Mains real power 0/4 mA [1] -9,990 to 9,990 kW; [4] -6,900 to 6,900 kW
The scaleable analog input is assigned a numerical value, which corresponds to the
lowest input value  (0 % corresponds to -500 kW; 0 or 4 mA).
Parameter 37
Analog in Pmains
100% 0000kW
Package XP, Option T701 only
Mains real power 20 mA [1] -9,990 to 9,990 kW; [4] -6,900 to 6,900 kW
The scaleable analog input is assigned a numerical value, which corresponds to the
highest input value  (100 % corresponds to 500 kW; 20 mA).
Mains current measurement via mains CT
Parameter 38
Current transf.
mains 0000/x
Mains current transformer 5 to 7,000/{X} A
The input of the CT ratio is necessary in order to display and control the actual val-
ues. The CT ratio must be selected so that at maximum power the CT is at 60 % of
the converter's nominal current flow. A lower percentage may lead to malfunctions
due to loss of resolution. Additional inaccuracies in the control and monitoring
functions also occur.
{x} = 1 A ....... Secondary rated current = 1 A at primary rated current = {X} A;
{x} = 5 A ....... Secondary rated current = 5 A at primary rated current = {X} A;
{X} ................ e. g. from the main series 10, 15, 20, 30, 50 or 75 A and the decimal
fractions and multiples of these or the corresponding secondary se-
ries with 12.5, 25, 40 or 60 A.
