7.1. Configuration

The VAC control automatic comes with the following configuration:
pressure values = mbar (hPa)
manual mode = H1
automatic-parameters = "35"
Edit this basic configuration:
turn item OFF; depress "Auto" key and hold depressed
while turning the item OB again.
the "Act Vac" display first shows the unit chosen. Using the
arrow keys, you may either select "hPa" (mbar) or "Torr".
We recommend to use the "hPa" (mbar) mode.
depress "Set" key, "H1" is displayed. You may change to
"H2" with the arrow keys. "H1" is the standard regulating
mode. vacuum valve is opened and closed normally. "H2"
is going to open the vacuum valve for a second only; this
way it is easier to maintain nominal values.
Using a switchbox, "H1" is the only operational mode available.
