THIS MENU IS USED FOR THE PROCESS CONTROL OF THE TURBINE.
01 PROCESS CONTROL ENABLED
Displays the state of the process control. TRUE means the Process Control is enabled, FALSE means it
is disabled.
02 USE PROCESS CONTROL? dflt=FALSE(FALSE, TRUE)
The Process control can be configured to control any system process, related to or affected by turbine
speed or load. Typically this controller is configured and used as a turbine inlet or exhaust pressure
controller. When this value is set TRUE, the Process PID can move the speed setpoint at a variable rate
up to the REMOTE PROC MAX RATE setting. If the USE PROCESS CONTROL is FALSE the inputs will
have no effect on the control.
03 INVERT PROCESS? dflt= FALSE(FALSE, TRUE)
Select TRUE if the process control will be reverse acting. If FALSE is selected, the control will be forward
acting. Typically this will be set to FALSE, the only time the input would be inverted is if the valve needs
to open when the input exceeds the setpoint. An example where the invert would be TRUE is for turbine
inlet pressure control.
04 MIN PROC SETPT (UNITS) dflt=0.0 (-32000.0, 32000.0)
This value is the minimum setpoint value that the process setpoint can be decreased/lowered to (lower
limit of process setpoint). This value should set to the same value as the INPUT#X MIN VALUE (UNITS)
under the Configure menu D**ANALOG INPUT OPTIONS**.
05 MAX PROC SETPT (UNITS) dflt=0.0 (-32000.0, 32000.0)
This value is the maximum setpoint value that the process setpoint can be increased/raised to (upper limit
of process setpoint). This value should set to the same value as the INPUT#X MAX VALUE (UNITS)
under the Configure menu D**ANALOG INPUT OPTIONS**.
(Must be greater than the ‘Min Proc Setpt’ Setting)
06 PROC SETPT RT (UNITS/SEC) dflt=5.00 (0.01, 1000.00)
This value is the rate (in units per second) at which process setpoint moves when adjusted.
07 USE SETPOINT TRACKING? dflt= FALSE(FALSE, TRUE)
If TRUE, the process setpoint tracks the process input to provide bumpless transfer to process control
when it is enabled. If FALSE, the process setpoint remains at the last position except on power-up.
08 SETPT INIT VALUE (UNITS) dflt=0.0 (-32000.0, 32000.0)
When not using the Setpoint Tracking function, this is the value that the process setpoint initializes to
upon power-up.
(Must be less than or equal to the ‘Max Process Setpt’ Setting)
09 SPD SETPT LOW LMT (RPM) dflt=0.0 (0.0, 32000.0)
Set the minimum speed setpoint that the process controller can lower the speed setpoint to. To protect
the unit, this value should be at or above rated speed if the unit is a generator. (Must be greater than or
equal to the ‘Minimum Governor Speed Setpt’ Setting)
10 SPD SETPT HIGH LMT (RPM) dflt=0.0 (0.0, 32000.0)
Set the maximum speed setpoint that process controller can raise the speed setpoint to.
(Must be less than or equal to the ‘Maximum Governor Speed Setpt’ Setting)
11 PROCESS PID PROP GAIN dflt=1.0 (0.0, 100)
Enter the process PID proportional gain value. This value is used to set process control response.
12 PROCESS PID INTEG GAIN dflt=0.3 (0.001, 50.0)
Enter the process PID integral gain value. This value is used to set process control response.
