1 Safety Information
Before commissioning,
-
check the instrument and any accessories supplied
-
read the operating instructions
-
ensure that the instrument is suitable for your application.
If the instrument is not handled correctly, or if the operating instructions and specifications
are not adhered to, damage to property or personal injury can result.
2 Functions of the EDS 8000
Depending on which model you have, the instrument offers the following functions:
• Display of the actual pressure in psi, Mpa or bar
• Switching of the switch outputs in accordance with the pressure and the pre-set
switching parameters
• Menu navigation in accordance with the VDMA standard 24574-1
• Coloured LED backlight indicates the switching status
3 Installation
The EDS 8000 can be mounted directly via the pressure connection or indirectly
on a hydraulic block using a hose or a minimess line
(for torque value, see Chapter 9 - Technical specifications).
For optimum alignment, we recommend connecting the EDS 8000 mechanically using a
rotating adapter (for Mechanical Accessories see Chapter 12.2).
The electrical connection must be carried out by a qualified electrician according to the
relevant regulations of the country concerned (VDE 0100 in Germany). The housing of
the pressure switch must be properly earthed. When fitting into a hydraulic block, it is
sufficient if the block is earthed via the hydraulic system. When installing with a minimess
hose, the housing must be earthed separately (e.g. with a screened cable).
CAUTION:
The EDS 8000 must be fitted using a suitable open-end wrench
(across flats 27) on the hexagon nut of the pressure connection.
Do not install the EDS 8000 by gripping the housing, as this would damage the
housing or the entire instrument.
Additional installation suggestions which, from experience, reduce the effect of
electromagnetic interference:
• Make line connections as short as possible
• Use screened cabling (e.g. LIYCY 4 x 0.5 mm²)
• The cable screening must be fitted by qualified personnel subject to the ambient
conditions and with the aim of suppressing interference
• Keep the unit well away from the electrical supply lines of power equipment, as well
as from any electrical or electronic equipment causing interference
