4-13 Performing Manual Control
4-13-1 Manual Operation
With standard models, the MV is manipulated directly. With position-proportional
models, the MV is manipulated through the amount of valve
opening or by parameter settings.
The manipulated variable can be set in manual mode if the PV/MV parameter
is displayed in the manual control level. The final MV used in automatic
mode will be used as the initial manual MV when moving from
automatic mode to manual mode. In manual mode, the change value will
be saved immediately and reflected in the actual MV.
Manual operation can be used only for PID control.
Standard Models The automatic display return function will not operate in manual mode.
Balanceless-bumpless operation will be performed for the MV when
switching from manual operation to automatic operation. (See note.)
If a power interruption occurs during manual operation, manual operation
will be restarted when power is restored using the same MV as when
power was interrupted.
Switching between automatic and manual operation is possible for a maximum
of one million times.
The overall manual operation is illustrated in the following figure.
