3 Installation
3.1 Installation
•
Do not install the product unless the safety instructions have been read
and understood.
•
Protect from impacts using an ATEX enclosure suitable for
impacts.
3.2 Environment
•
Do not use in an environment where the product is directly exposed to
corrosive gases, chemicals, salt water, water or steam.
•
Do not use in an explosive atmosphere, except Zone 2/22.
•
The product should not be exposed to prolonged sunlight. Use a
protective cover.
•
Do not mount the product in a location where it is subject to excessive
vibrations and/or impacts.
•
Do not mount the product in a location exposed to radiant heat.
•
Remove emissive heat.
•
Employ suitable protective measures in locations where there is contact
with water droplets, oil or welding splatter, etc.
•
When the solenoid valve is mounted in a control panel or is energised for
a long time, make sure the ambient temperature is within the valve
specification range.
3.3 Piping
•
Before piping make sure to clean up chips, cutting oil, dust etc.
•
When installing piping or fittings, ensure sealant material does not enter
inside the port. When using seal tape, leave 1.5 to 2 threads exposed on
the end of the pipe/fitting.
•
Install piping so that it does not apply pulling, pressing, bending or other
forces on the valve body.

•
Tighten fittings to the specified tightening torque shown in Table 1.

3.4 Electrical Connection
•
The manifold has negative common (-COM).
•
Avoid mis-wiring, as this can cause malfunction, damage and
combustion to the product.
•
Use voltage that is within ±10% of the rated voltage. Application of
incorrect voltage may cause malfunction or damage.
•
To prevent noise and surge in signal lines, keep all wiring separate from
power lines and high voltage lines. Otherwise this can cause
malfunction.
•
Use electrical circuits that do not generate chattering in their contacts.
•
Do not bend or pull cables repeatedly.
•
Disconnect power supply before removing or making electrical
connections

3.5 Mounting
•
Never remove a valve from the manifold when energised.
•
Never remove terminal box cover when power is connected to the
manifold.
•
Never disconnect or reconnect cables or connectors when power is
connected to the manifold.
•
Install 56-VQC valves only.
•
Install 56-VV5QC manifolds only, as it has an integrated power saving
circuit.
56-VQC1000/2000 Valve mounting:
Figure 11
Removal procedure:
•
Loosen clamp screws until they turn freely (they do not come out).
•
Remove the solenoid valve from Clamp B by lifting the coil side of the
valve, while pushing on the screw top.
3 Installation (continued)
Mounting procedure:
•
Push the clamp screw. Clamp A now opens.
•
Insert the end plate hook of the valve into Clamp B from an angle.
•
Push the valve down into place (when the clamp screw is released,
Clamp A will lock).
56-VQC4000 Valve mounting:
Figure 12
Removal procedure:
•
Loosen mounting screws until they turn freely.
•
Remove the solenoid valve from Clamp B by lifting the coil side of the
valve first.
Mounting procedure:
•
Push the coil side of the valve into the connector on the manifold.
•
Tighten the mounting screws to torque 0.8 to 1.2 N•m.
•
Ensure all gaskets are present before mounting valves.
•
Do not let foreign matter stick to gaskets or sealing faces of the valve to
avoid air leaks
3.6 Lubrication
•
SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
•
If a lubricant is used in the system, use turbine oil Class 1 (no additive),
ISO VG32. Once lubricant is used in the system, lubrication must be
continued because the original lubricant applied during manufacturing
will be washed away.
4 Settings
4.1 Manual Override
•
Since connected equipment will operate when the manual override is
activated, confirm that conditions are safe prior to activation.
Non-locking push type (tool required)
•
Push down the manual override button with a small screwdriver, etc.
until it stops.
•
The manual override will return when released.
Figure 13
Slotted locking push type (tool required)
•
Push down the manual override button with a small flat head screwdriver
until it stops and turn 90° clockwise to lock.
