Installation
2.1
Functional properties
Before installing the CEM, check the serial number label to see if the functional properties match
your requirements:
·
Instrument type (technical properties; see
Model key
)
·
Flow rates (gas and liquid)
·
Media to be used in the instrument
·
Power supply
Test pressure
Bronkhorst® instruments are pressure tested to at least 1.5 times the specified working process
conditions and outboard leak tested to at least 2 * 10
-9
mbar l/s Helium. The tested pressure is specified
on the instrument with a red label.
·
Before installation, make sure that the tested pressure is in accordance with the safety factor of your application
·
If the pressure test label is missing or if the specified pressure is insufficient, the instrument must not be used and should
be returned to the factory
·
The maximum operating pressure must never exceed the tested pressure
·
Disassembling the instrument and/or replacing parts of it will invalidate the pressure test specification.
2.2
Mounting
The CEM must be mounted vertically, with the control valve up and the vapour outlet pointing down (as shown in the
product overview
).
For optimal performance, please observe the following:
·
Use the mounting holes on the rear to attach the CEM to a rigid and stable construction. Check the
dimensional drawing
for the exact positions and size of the mounting holes
·
Avoid installation in close proximity of mechanical vibration and/or heat sources.
2.3
Electrical connection
Electrical connections must be made with standard cables or according to the applicable hook-up diagrams. Make sure that
the power supply is suitable for the power ratings as indicated on the serial number label or in the technical specifications
of the instrument, and that double or reinforced insulation is used for the power supply.
The device contains electronic components that are susceptible to damage by
electrostatic discharge
. Proper handling
procedures must be followed during installation, (dis)connecting and removing the electronics.
The device described in this manual carries the CE-mark and is
compliant with the concerning EMC requirements
.
However, compliance with the EMC requirements is not possible without the use of proper cables and connector/gland
assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and if loose
ends are used, these are marked to help prevent wrong connection. When using other cables, cable wire diameters should
be sufficient to carry the supply current, and voltage loss must be kept as low as possible. When in doubt, contact your local
Bronkhorst representative.
When connecting the product to other devices, be sure that the integrity of the shielding is not affected;
always use
shielded cabling for signals and communication and do not use unshielded wire terminals.
