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").
