1. Install valve [1] into the vacuum system.
Caution: Do not tighten the flange screws stronger than indicated under «Tightening torque».
Caution: Do not admit higher forces to the valve than indicated under «Admissible forces».
Note: Make sure that enough space is kept free to do preventive maintenance work. The required space is indicated
on the dimensional drawing.
Note: Control unit of valves with ISO-KF flanges (612 . . –K. . . ) needs support when mounted on horizontal piping
and control unit does not hang.
2. Install the ground connection cable at controller. Refer to «Electrical connection»
3. Install sensor(s) [2] according to the recommendations of the sensor manufacturer and directives given under
«Requirements to sensor connection».
4. Connect sensor cable [3] to sensor(s) and then valve (connector: SENSOR).
Refer to chapter «Electrical connection» for correct wiring.
Note: Input for second sensor is available on 612 . . - . . . Nversions.
5. Connect valve (connector: INTERFACE) to remote control unit [4]. Refer to «CC-Link schematics» for correct wiring.
6. Connect power supply [5] to valve (connector: POWER). Refer to chapter «Electrical connection» for correct wiring.
Note: 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».
7. This valve may optionally be equipped with a heating device. Connect VAT heating device according to manual of
respective heating device.
8. Perform «Setup procedure» to prepare valve for operation.
Note: Without performing the setup procedure the valve will not be able to do pressure control.

2.5 Requirements to sensor connection
To achieve fast and accurate pressure control a fast
sensor response is required.
Sensor response time: < 50ms
The sensor is normally connected to the chamber by a
pipe. To maintain that the response time is not degraded
by this connection it needs to meet the following
requirements:
Inner diameter of connection pipe: > = 10 mm
Length of connection pipe: < = 300 mm
These conductance guidelines must include all valves and
limiting orifices that may also be present.
Make also sure that there is no obstruction in front of
sensor connection port inside the chamber.
The sensor should also be mounted free of mechanical
shock and vibration.
Dynamic stray magnetic fields may introduce noise to
sensor output and should be avoided or shielded.

2.6.2 Sensor supply concepts
This valve offers 3 alternative concepts to supply the sensor(s) with power. This depends on the sensor type and valve
version that is used. This valve is available with an optional sensor power supply module (SPS) that converts 15 VDC
from the 24 VDC.
Concepts:
External + 24 VDC supplied to POWER connector is feed through to SENSOR connector to supply 24 VDC
sensors. Refer to chapter «2.6.3 Power and sensor connection (+24 VDC sensors)» for schematic and correct
wiring.
External 15 VDC supplied to POWER connector is feed through to SENSOR connector to supply 15 VDC
sensors. Refer to chapter «2.6.4 Power and sensor connection ( 15 VDC sensors) without optional SPS module»
for schematic and correct wiring.
External + 24 VDC supplied to POWER connector is converted into 15 VDC by the valve internal SPS and
supplied to SENSOR connector to supply 15 VDC sensors. Refer to chapter «2.6.5 Power and sensor
connection ( 15 VDC sensors) with optional SPS module» for schematic and correct wiring.
Valve versions:
612 . . - . . G. - . . . . / 612 . . - . . H. - . . . . SPS module not included
612 . . - . . A. - ..../ 612 . . - . . C. - . . . . SPS module included
Note: The SPS module can be retrofitted. Refer to chapter «Retrofit / replacement procedure» for instruction.

[612 . . - . . G. - . . . . / 612 . . - . . H. - . . . . versions recommended]
2.6.3.1 Sensor power wiring via controller
Note:
Use shielded sensor cable(s). Keep cable as short as possible, but locate it away from noise sources.
Connect the +24 VDC sensors at DB–15 female sensor connector exactly as shown in the drawing above.
Do not connect other pins that may damage sensors, power supply or controller!
Connector: Use only screws with 4-40UNC thread for fastening the connectors!
Pins 4 and 8 must be bridged for operation!
An optional switch would allow for motor
interlock to prevent valve from moving.
Low range sensor may be connected
to sensor 1 or sensor 2 input.
Do configuration accordingly.
