Power Set point Value
NOTE
The SPM-D11 does not take the connection to the utility into consideration. This means that if the plant
generates excess power, power will be exported to the utility. If the plant does not generate enough
power to meet demand, then power will be imported from the utility. This power controller does not
perform process control.
Power controller
P set1 = 0000kW
Set value 1 Real power controller
0 to 9,999 kW
Setting of the internal power set value 1( Pset 1). If this set point is selected, this is
the reference value for controlling the real power.
Power controller
P set2 = 0000kW
Set value 2 Real power controller
0 to 9,999 kW
Setting of the internal power set value 2 (Pset2). If this set point is selected, this is
the reference value for controlling the real power.
Power set point
External ON
External set value
ON/OFF
Selection of the external power set point. If this set point is selected, the real power
is controlled to the external power set reference value.
Analog input
0..00mA
External set point value: Range
0 to 20 / 4 to 20 mA
The analog reference signal input of the real power controller can be switched be-
tween 0 to 20 mA and 4 to 20 mA depending on the remote set point signal.
0
to 20 mA
... Minimum value of the set point value: 0 mA; Maximum value:
20 mA.
4
to 20 mA
... Minimum value of the set point value: 4 mA; Maximum value:
20 mA. Wire break monitoring is performed.
External setp.
0mA 0000kW
Scaling the minimum value
0 to 8,000 kW
The minimum value of the real power set point is defined here.
External setp.
20mA 0000kW
Scaling the maximum value
0 to 8.000 kW
The maximum value of the real power set point is defined here.
External setp.
Value = 000kW
Display of the current set point value
0 to 8,000 kW
This screen is not used to enter a value, but to display the current measured value,
calculated into kW, of the analog input. This permits the mA signal to be validated
even if the engine is stopped.
Power controller
Ramp 000 kW/s
Real power controller set point ramp
1 to 999 kW/s
A change in set point is supplied to the controller via a ramp. The slope of the ramp
is used to alter the rate at which the controller follows the set point value. The more
rapidly the set point should change, the greater should be the value set here.
