Fig. 5-203: PID input pressure control
NOTES When the control switches between the first PID control and second PID control while the set
point is changed by the Pr. 1380 setting value or while the Y229/Y230 signal is output, the set
point returns to its original value or the signal turns OFF, and the detection restarts.
When the PID input pressure control function and the PID upper/lower limit pre-warning function
are used simultaneously, each function may change the set point. When the set point change is
attempted by both functions, the change by the PID input pressure control function has priority.
When the PID input pressure control function and the PID sleep boost function are used simulta-
neously, each function may change the set point. When the set point change is attempted by both
functions, the change by the PID input pressure control function has priority. (The sleep state is
established without applying the set point change by the PID sleep boost function.)
