For 900-TC8 and 900-TC16, if an event input is configured to MANU
(Auto/Manual), the Auto/Manual Switch parameter will not be displayed. Use
the event input to switch between automatic and manual modes.
Note: Even when controller operation is stopped, the manual control of the
MV is given priority over other functions.
Controller auto-tuning and self-tuning will stop when the Manual Mode
is entered.
Note: If the SP ramp function is operating, it will continue even when the
manual mode is entered.
