Principle of Operation
The pressure in the zone to be protected (generally
the pipeline on the outlet side of the pressure
regulator and situated after the slam-shut device
(see Figures 5 and 7) activates the VSX4 and
VSX8 Series controller.
The pressure measuring element of the
VSX4 and VSX8 Series controller consists of a
diaphragm that senses downstream pressure. The
downstream pressure is controlled by the regulator
(Figure 7). The top side of the VSX4 and VSX8 Series
diaphragm encounters the force imposed by the
overpressure shut-off spring and underpressure
shut-off spring.
When the downstream pressure increases above the
overpressure shut-off (OPSO) setting, the diaphragm
moves up.
When the downstream pressure decreases below the
underpressure shut-off (UPSO) setting, the diaphragm
moves down.
Both of these actions result in the rotation of the cam
and the release of the reset pin.
The valve plug spring moves the valve plug against
the regulator port, stopping the ow of gas.
Before opening the valve plug, an equal pressure
balance on inlet and outlet sides is required.
Refer to the VSX4 and VSX8 Series Instruction
Manual, Form 5867. Using the reset button, activate
the internal bypass, then rearm the valve plug in
accordance with the Manual Reset Procedure.
Rearming and pressure balancing are achieved at the
same time.

General Installation Instructions
Note
The VSX4 and VSX8 Series can be rotated
360° for easy installation and maintenance.
• Install according to EN 12186 and EN 12279.
Before proceeding to installation:
• The slam-shut device must be compatible with the
gas being regulated.
• Check for damage, which might have occurred
during shipment.
• Check for and remove any dirt or foreign material,
which may have accumulated in the regulator or
slam-shut device body.
• Blow out any debris or dirt in the tubing and
the pipeline.
• Ensure that the external sense orice is clean.
• Apply pipe compound to the external threads of the
pipe before installing the slam-shut device.
• Verify these points:
- Equipment limits of utilization (PS, TS) correspond
to the desired operating conditions.
- The inlet is protected by an appropriate device(s)
to avoid exceeding the allowable limits (PS, TS).
- The slam-shut device and its springs correspond
to the desired operating conditions of the
associated regulator.
• When assembling piping and anges, do not apply
excessive pressure force on the body and the bolts,
O-rings, anges or ttings. All connections should
be compatible with the geometry and working
conditions of the pipeline.
• If needed, a support may be used under the piping
and regulator / slam-shut device body to avoid
excessive pressure force on the regulator / slam-
shut device.
Figure 6. Controller Manual Bypass
• Connect downstream control line tubing to the
1/4 NPT connection in the lower casing, and run
the tubing downstream of the regulator outlet a
minimum distance of 4 times the outlet pipe diameter
(see Figure 7).
• Periodically check all vent openings to be sure that
they are not plugged.

Step 1:
• Slowly pull the reset button (key 30) away from the
controller. This slow movement allows for a slow
bleed of the pressure across the controller’s disk
and seat area. The operator should be able to hear
the pressure bleeding through the system.
Step 2:
• When the pressure has equalized and the air
bleeding sound has dissipated, the reset button
(key 30) can be pulled completely away from
the controller by hand until the internal shut-off
mechanism has been re-latched.
Step 3:
• Once the operator feels the click of the re-latch
occurring, the reset button (key 30) should be
pushed completely back into its original position.
