There are five programs up to 99 steps each
to be used as a programed vacuum controller which allows
programming of fixed-value control, slope control and
release to the atmosphere.
Fixed-value control will be made for the set time .
In slope control, decompression will be made at the set time
from the slope start
pressure
（
set pressure of the
previous step
）
to the set pressure.
You can set a step program on the Program setting screen.
The items and the initial values of the steps are as follows:

* Setting the control condition select (Condition) to
Step starts the fixed value control and setting it
Slope start slope control.
* Setting priority condition select (Priority) to Press
continues the present step until the set pressure is
attained after the set time has elapsed.
When it is set to Time, the process will move to the
next step when the step operation time has
elapsed.
* For the inverter pump, you do not need to set a
hysteresis (ΔP).
You can set program operations on the Program setting
screen. The items and the initial values are as follows:
