Auto run (AUTO)/manual run (MANU)

The base of a run is the auto run (AUTO); the auto run, however, changes to the manual run (MANU) by
holding the AUTO/MANU key pressed for 3 seconds.
No control is performed during a manual run, but the operation amount is output in a display.
The displayed operation amount is identical to the SV displayed in the lower row on the PV/SV screen in the
normal mode.
Pressing the / key in this status results in a change of the operation amount to be output.
The operation amount and step time are as follows at the start of a manual run:

Operation amount

In the case of in-a-stop: Starts with the operation amount of 0.0%.
In the case of in-a-run: Starts with the operation amount at the time of switchover

Step time

In the case of in-a-stop: Remains in a stop (no step time counting begins).
In the case of in-a-run: The step time elapses (remains in a stop during a momentary stop).

Re-holding the AUTO/MANU key pressed for 3 seconds results in a return to the auto run.
The AUTO and MANU lamps lights up as follows:

During an auto run: The AUTO lamp turns on and the MANU lamp turns off.
During a manual run: The AUTO lamp turns off and the MANU lamp turns on.

The output interval during a manual run is fixed to 10 seconds.
