In the "Temperature" menu the user can specify that the tempera-
ture sensor is displayed on the display/working screen. A tick ()
shows that the option is activated.
The precondition for this is that a temperature sensor is connec-
ted to the vacuum controller. If no temperature sensor is con-
nected, or an error is present or the temperature rises above
350 °C, three dashes are shown as the temperature value.
Please comply with the tempera-
NOTICE
ture measurement range of the ex-
ternal temperature sensor speci-
fied in the "Technical data" section.
The temperature display can be in
either °C or °F (see the "Settings"
menu).
Calibration
In order to calibrate the external temperature sensor, it must first
be connected to the vacuum controller. The temperature sensor
is then immersed in a vessel with water, for example. The water
temperature is determined using a second, already calibrated tem-
perature measuring device. The measured temperature must then
be entered in the menu under "Temperature calibration". Once
the entry has been confirmed with "OK", the external temperature
sensor is calibrated.
In the "Timer" menu the user can specify that the timer is dis-
played on the display/working screen. A tick () shows that the
option is activated. This setting allows the user to specify the actu-
al time for the evacuation procedure.
A default time can also be set for the timer. This setting allows the
user to start evacuation for a standard time. The device can emit a
signal (beep) after the set target time has elapsed.
The user can stop the evacuation

procedure before expiry of the set
time. In this case the countdown
of the timer is interrupted.

Operating mode A:
In this operating mode, the set target value is not saved when the
current run comes to an end or the device is switched off.
Operating mode B:
In this operating mode, the set target value is saved when the
current run comes to an end or the device is switched off, and the
value can be changed.
Operating mode C:
In this operating mode, the set target value is saved when the
current run comes to an end or the device is switched off, and the
value cannot be changed.
Operating mode D:
In this operating mode, the target value is applied if it does not
change after 3 seconds, or when the yellow background is dis-
played behind the target value. In operating modes A and B, the
target value is applied immediately when the target value is chan-
ged by turning the knob.
In operating mode C, the target value cannot be changed.
In the "Display" menu the user can specify what information will
be displayed on the main screen.
Select:
To select a program, use the rotating/pressing knob and press "Se-
lect". Only programs that have at least one program segment can
be selected.
When a program has been successfully selected, this is indica-
ted by a tick mark (). The vacuum controller is then in program
mode. In the main screen, the program view can then be selected
by turning the knob to the right. Turning the knob to the left re-
turns the user to the main screen.
Start:
To start a selected program, the push knob must be pressed in the
main screen.

Edit the selected program parameters. Start to edit the selected
program parameters by pressing on menu option "Edit" with rota-
ting/pressing knob. The user can edit, delete or insert one selected
program segment in the program.
Delete:
Deletes the selected program. If a selected program is deleted by
pressing on menu option "Delete" with rotating/pressing knob, all
the program parameters will be emptied. The tick () disappears.
