2 0.01 to 100.00 The integral gain identifies the I part of the PID controller. The integral gain
corrects for any offset (between setpoint and process variable) automatically
[1.00]
over time by shifting the proportioning band.
Reset automatically changes the output requirements until the process vari‐
able and the setpoint are the same. This parameter permits the user to adjust
how quickly the reset attempts to correct for any offset. The integral gain con‐
stant must be greater than the derivative time constant.
If the integral gain constant is too large, the engine will continually oscillate. If
the integral gain constant is too small, the engine will take too long to settle at
a steady state.

2 0.01 to 100.00 The derivative ratio identifies the D part of the PID controller. By increasing
this parameter, the stability of the system is increased.
[0.01]
The controller will attempt to slow down the action of the actuator in an
attempt to prevent excessive overshoot or undershoot.
Essentially this is the brake for the process. This portion of the PID loop oper‐
ates anywhere within the range of the process unlike reset.

The default configured controller acts like a PI controller what is the valid D
part setting for systems with secondary controllers.
1 0.001 to 0.300 The generator power factor is controlled in such a manner, when paralleled
with the mains, so that the monitored power factor does not deviate from the
[0.010 %]
configured power factor setpoint by more than the value configured in this
parameter without the controller issuing a raise/lower signal to the voltage
regulator.
This prevents unneeded wear on the raise/lower relay contacts.

[0.05 s] The shortest possible pulse time should be configured to limit overshoot of
the desired power factor reference point.
