2. Connect compressed air supply to connection labeled 'IN' located at actuator, see Figure 1 below.
Connect compressed air return line connection labeled 'OUT' located at actuator, see Figure 1 below.
3. Install the ground connection cable at controller. Refer to «Electrical connection»
4. Install pressure sensor(s) [2] according to the recommendations of the sensor manufacturer and
directives given under «Requirements to sensor connection».
5. Connect sensor cable [3] to sensor(s) and then to valve (connector: SENSOR).
Refer to chapter «Electrical connection» for correct wiring.
6. Connect valve to Logic [4] (connector: INTERFACE). Refer to «Function and Wiring» for correct
wiring.
7. Connect power supply [5] to valve (connector: POWER). Refer to chapter «Electrical connection» for
correct wiring.
8. This valve has a double sealed rotary feedthrough and optionally an intermediate pumping port for the
actuator shaft. This port (1/8" ISO/NPT) could be connected to the vacuum line, see Figure 2 below.
9. This valve may optionally be equipped with a heating device. Connect VAT heating device according
to manual of respective heating device.
10. Perform «Setup procedure» to prepare valve for operation.

INSTALLATION
•
Do not admit higher forces to the valve than indicated under «Admissible forces».
•
Make sure that enough space is kept free to do preventive maintenance work.
The required space is indicated on the dimensional drawing.
•
Compressed air pressure must be in the range of: 4 - 7 bar / 55 - 100 psi (above
ATM).
•
Use only clean, dry or slightly oiled air. IN / OUT connections are 1/8" ISO/NPT
internal threads.
Input for second sensor is available on 651 . . - . . . E - . . . . version only.
To provide power to the valve motor pins 4 and 8 must be bridged, otherwise motor
interlock is active and the valve enters the safety mode and is not operative. Refer
also to «Safety mode».
Without performing the setup procedure the valve will not be able to do pressure
control.
