• Using the PF Key to Move to the Manual Control Level
• If the PF Setting parameter is set to A-M (auto/manual), you can change to manual operation
(Manual Control Level) by pressing the PF Key for at least one second from the Operation Level,
Program Setting Level, Adjustment Level, or PID Setting Level. During manual operation it is not
possible to move to any displays other than PV/MV (Manual MV). Press the S or O Key for at
least one second from the PV/MV display in the Manual Control Level to change the mode to
Automatic Mode, move to the Operation Level, and display the top parameter in the Operation
Level.
Note1: Priority of Manual MV and Other Functions
Even when the program is in reset status, the manual MV is given priority.
Autotuning will stop if you change to manual operation.
2: Manual Operation and Program Operation
Timing will continue when you move to manual operation during program operation.
• Moving to the Manual Control Level with an Event Input
• If an event input is set to MANU (auto/manual), you can use the event input to switch between
Automatic Mode and Manual Mode.
We will set the PF Setting parameter to A-M (auto/manual).
If the PID ON/OFF parameter is set to ON/OFF, you must change the
setting to PID.
