Manual Control

A manipulated value (MV) can be set manually by users without being automatically calculated using the PID control.
Setting method
Configure the settings as described below.
1.
Set 'CH1 AUTO/MAN mode shift' (Un\G518) to Manual (MAN) (1). (Page 149 CH1 AUTO/MAN mode shift)
2.
Set the manipulated value (MV) in 'CH1 Manual output setting' (Un\G519). (Page 150 CH1 Manual output setting)
