Connecting the interfaces
Connect the vacuum hoses, pay attention to the following con-
nections (also see Fig. 1):
J: Load
Hose connection d=10 mm to the system to be evacuated (reci-
pient).
K: Pump
Hose connection d=10 mm to the vacuum source (e.g. pump).
I: Vent
Ventilation connection d=10 mm, also suitable for the connection
of inert gas.
Secure the hoses with hose clamps, if necessary.
Lay the vacuum hoses according to your device configuration.
Now connect the connecting cables according to your system
configuration:
L: Mini USB Interface
Connect the VC 10 lite/pro vacuum controller to a PC using the
USB 2.0 cable (A/Micro-B).
Software updates to any existing equipment can be installed using
the FUT software tool.
M: RS 232 Interface
You can connect the VC 10 lite/pro vacuum controller to a PC
using an RS 232 interface cable. The pump can be operated in
conjunction with other devices using labworldsoft
®
laboratory
software. For more information see Chapter "Interfaces and out-
puts".
P: PT 1000 temperature sensor (VC 10 pro)
Connect the optional PT 1000.60, PT 1000.61 or PT 1000.70
temperature sensor (accessory). The measured temperature (e.g.
tempering bath) is shown on the display.
The value displayed is for information purposes only and is not
processed logically.
Two-position control
Vacuum pump/vacuum source with VC 10 pro vacuum controller.
Once the target value is reached, the suction line is closed by the
vacuum valve integrated in the VC 10 pro vacuum controller. The
pump speed can be changed by manually adjusting the speed set-
ting.
For pumps which have the speed setting option, it is recommen-
ded to work at low speed.
When using the VACSTAR vacuum
NOTICE
pump: The pump must be opera-
ted in mode "B" (restart after vol-
tage drop).
The vacuum source can also be a central in-house vacuum net-
work.

Note that the value displayed is dependent on the positioning of
the sensor in the medium, its mixing, as well as the calibration
of the probe and can deviate from other measured temperature
values.
Incorrect or fluctuating measured values can be displayed by using
a heating bath, e.g. by laying the sensor on the heating bath floor,
instead of positioning in the medium.
Q: VACSTAR membrane vacuum pump (Mini DIN)
You can connect the vacuum controller and the VACSTAR vacu-
um pump to the analogue connection cable (accessory) for exact
speed-controlled vacuum control. The vacuum controller detects
the pump and switches to speed-vacuum control mode. The two-
position control is disabled. The pump speed is regulated depen-
ding on the measured pressure.
R: Connector for 24 W AC adapter
Connect the universal AC adapter (included) to the socket on the
rear. Observe the country-specific variants of the AC adapter!

2 Separator (Woulff bottle)
3 Venting valve
4 Pressure sensor
5 Vacuum valve/ball valve
7 Vapour condenser
8 Connection cable (analogue)
9 Vacuum source (pump, in-house vacuum)

Illustration two-position control - vacuum pump/vacuum source with vacuum controller VC 10 pro
Vacuum source with two VC 10 pro vacuum controllers.
Once the target value is reached in a recipient, the suction line is
closed by the vacuum valve integrated in the VC 10 pro vacuum
controller.
A sufficiently stable vacuum source (in-house vacuum, pump) can
serve multiple consumers.
Illustration two-position control - vacuum source with two vacuum controllers VC 10 pro
For pumps which have the speed setting option, it is recommen-
ded to work at low speed.
A second consumer can be controlled independent of the first
using a second vacuum controller.
