PID Settings
On the Control Gain screen, click the tool bar PID button to open the PID window. (The Control Gain
screen Stability Range setting must be 21.) Use the PID window to select the correct PID values based
on generator time constant T’do and exciter time constant Te. For more information about PID settings,
refer to Section 5,
BESTCOMS Software, PID Window .
The following suggested settings may be used for AVR and FCR modes when the generator and exciter
time constants are unknown.

OFF-LINE TESTS - TURBINE SPINNING
For off-line tests with the turbine spinning, the generator circuit breaker is open.
FCR Mode
Initial testing should be conducted in FCR (manual) mode and minimum generated voltage.
Place the DECS-200 in FCR mode............................................................................................... ________
Place the Start/Stop switch in the Start position ........................................................................... ________
NOTE
If proper startup is not achieved, increase the value of loop gain (Kg) for AVR
and FCR modes.
