3.3. SYSTEM
CONNECTION
IMPORTANT !
Ingress of foreign matter, however small, will cause serious
damage.
Such matter includes dust, sand, masonry debris, impurities in the
tubes, cutting burrs or filings, welding or soldering slag and
splatter, metal burrs and any residues from sealing and making the
tube connections.
To ensure proper installation, please note the following:
•
To connect the unit to the process lines, remove the flanges
and connect via flexible tubes;
•
Remember to protect the inlet with suitable filters;
•
To avoid using rigid couplings, which could induce stress and
cause harmful vibrations;
•
Only remove the plugs on the ports when making the final
connections;
•
Select the tube size and the couplings to minimize the
pressure drop, in particular:
-
Do not use tubing of a smaller diameter than the ports of
the device;
-
Utilise large radius bends and avoid using elbows.

CAUTION!
BEFORE UNDERTAKING ANY OPERATION ENSURE THAT
THE UNIT IS DISCONNECTED FROM POWER SUPPLY.

CONTROL
WARNING
BEFORE UNDERTAKING ANY OPERATION ENSURE THAT
THE UNIT IS DISCONNECTED FROM THE POWER SUPPLY.
The electromagnet has been selected for service in an ambient
temperature between 0°C and +35°C at an altitude no higher than
1000 m.
Verify the identification letter engraved on the back side of the
electromagnet. Line voltage values should be consistent with
following chart:
Identification

The current drawn refers to normal operating conditions.
Variations in the supply voltage up to ± 5% are acceptable.
IMPORTANT !
The magnet activation time (“ED”) is calculated as the time the
magnet is energized as a per cent of total cycle time and
should be equal to a maximum of 60% as indicated in table.
Exceeding this value could overheat the magnet and result in
premature failure. The maximum activation time is 5 minutes.
The electromagnets come supplied with appropriate connections
for quick installation.
The connections provided offer complete protection from water
ingress according to the norm DIN 40050 (Class IP65 level of
protection) when correctly installed using appropriate connecting
screws and sealing gaskets. In addition, units conform to
VDE0110-1/89, working voltage up to 300v, working level C
regarding class of insulation.
In order to wire the electromagnets, please use the following
instructions:
•
Remove the screws located on the upper part of the
connection and extract the last one from its support
•
Remove the terminal contacts from the protective cap on the
connector by use of a screwdriver.;these two components
have a release joint
•
Complete the wiring following the diagram on the terminal
connections by the use of locking screws
•
Reassemble in reverse order (do not forget the gaskets)
N.B. The terminal connectors and the external protection of the
connectors are able to be put in 4 different orientations. Select the
one most suitable for your installation.
IMPORTANT !
CHECK TO ENSURE PROPER GROUNDING
THE ENTIRE GUARANTEE SHALL CEASE TO APPLY WHEN
INADEQUATE PROTECTION IS PROVIDED.

Before commissioning in installation, make sure the air cylinders
are not under pressure.

OPERATION
4.1. PRELIMINARY
CONTROLS
Before commissioning, please ensure the following:
•
Should the unit need to be stored for a long period of time
before installation, ensure it is kept in a dry environment and
inspect prior to installation.
•
Check that there are no impurities that could obstruct the seal
between the shutter and body.
•
Ensure that all safety protectors have been properly installed.
4.2. START-UP
The VS6 / VS8 flow converters do not require any additional
controls. The 2 possible positions of the shutter are fixed by run
length the shutter is not able to be put in an intermediate / half-way
position.
A higher-than-allowed differential pressure on the actuator could
cause a lack of charge in the cylinder due to misalignment of the
shutter and seal rings.
