(The above figure is an image of Auto/Manual transfer of Input 1.)
When Auto/Manual mode is changed from Auto to Manual or from Manual to Auto, the
balanceless-bumpless function is activated to prevent control disturbance caused by a sudden output
change.
(a)
Transfer from Auto mode to Manual mode.
However, when the mode is transferred to Manual mode, the Manipulated output value used in Auto mode
will be used as the Manual output value in Manual mode.
(b)
The Manipulated output value is changed (Manual mode function)
(c)
Transfer from Manual mode to Auto mode.
When the mode is transferred to Auto mode, the controller starts PID control based on the MV used in
Manual mode.
For the Operation mode, refer to
