System properties (3)
This dialogue box is used to change the system settings.
Fig. 42: Dialogue box "System properties"
Beeper:
The beeper sounds in the event of a malfunction, for example.
• If the setting is "On", the beeper sounds at intervals of a few seconds
until the message is acknowledged.
• If the setting is "Silent", the beeper sounds once when the malfunction
occurs.
• If the setting is "Off", the beeper will not sound at all.
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. Selecting the button again
deactivates the function (button "controlled").
Access protection (4)
In this dialogue box, the access rights can be managed on several levels
and they can be protected with a password.
In the factory setting with activated access protection, data can be viewed
but not edited.
