Translation of the original operating manual
Click on touch: If this function is active, a clicking sound can be heard
whenever the system registers that a button has been touched.
Behaviour of the pressure control valve in the case of insufficient ice
condenser cooling: If this function is active (button "closed"), the pressure
control valve will close at an ice condenser temperature of 20°C during
the drying process in order to avoid damage to the vacuum pump caused
by the withdrawal of condensable gases. Pressing the button again
deactivates the function (button "controlled").
Access protection (4)
In this dialog box, the access rights can be managed on several levels and
they can be protected with a password.
In the factory setting with an activated access protection, data can be
viewed but not edited.

NOTE
The other buttons cannot be activated unless the access protection is
active.
Password timer runtime: In order to prevent unauthorised access, the
system will automatically switch back to the default setting after a pre-
defined period of time.
In this case, there is a small lock symbol in the status line and below this
symbol the remaining time until the lock will be active is counted down. At
the same time a button with a big lock symbol will be displayed in the actual
values field.
