Manual Operation (MAN OPER)
It is used to manually raise or lower the valve stem by operating the UP or DOWN buttons. This can
be used to observe the move of valve stem without any external input signals. When engaged, the
current input signal to the positioner has no effect on the positioner.
Use the Manual only when the operation is suspended, or when no trouble is raised with the
operation of Control Valve, as the execution of Manual Mode may interfere with the currently
operating process.
9.7.1
Manual Operation by Set position (MAN SP)
The target position is incremented by the UP and DOWN buttons based on the currently entered set
position values, which moves the stem of the valve up and down. Once out of the menu by <ESC>,
the positioner is controlled again by an input signal.
