The step changes when the external contact open (OFF) changes to the external contact closed (ON) during a
program run.
4.11.4
Patterns 1 to 4 DI
A pattern is selected from 1 to 15, which are configured by combination of the external contacts 1 to 4 closed (ON)
and open (OFF).
No switchover of a pattern No. is possible during a run.
If all external contacts 1 to 4 are open (OFF), choose the pattern No. selected in the pattern No. setting mode.
Pattern 1 DI: 1
Pattern 2 DI: 2
Pattern 3 DI: 4
Pattern 4 DI: 8
Example: If both pattern 1DI and pattern 3DI are ON, selected pattern No. is: 1 + 4 = 5.

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.

Operation amount limiter
By using the operation amount function selection, “no limit function” can be set or two types of operation
amount limiters can be effective.
In addition, two types of limiters can be effective by using the other operation amounts limiter setting described
in Section 4.13.3.
4.13.1
Operation amount limiter
The operation amount is limited by using the primary/secondary control operation amount upper limiters and
Primary/secondary control operation amount lower limiters selected by the operation amount limiter function
selection at each step.
If the operation amount limiter function selection is 0, then 0.0 to 100.0 % is applicable.
