Enter the process controller proportional gain.
Quick control is obtained at high amplifi-
cation. However if amplification is too great,
the process may become unstable

Enter the process controller integral time.
Obtain quick control through a short integral
time, though if the integral time is too short,
the process becomes unstable. An excessively
long integral time disables the integral action.
