3 Transportation, Package, Storage
3.1 TRANSPORTATION
The EDS 300 is supplied in a cardboard box.
When accepting and unpacking, make sure the item has been delivered in full and look out for any
possible transport damage. If present, immediately show it to the shipper.
3.2 PACKAGE
Do not remove the packing until you are ready to install the unit.
Keep the packing of the device for eventual reuse in case of transport (changing application areas)
or restorage, it provides the best protection for the device.
3.3 STORAGE
Permitted ambient conditions for storage (see also technical data):
-
Temperature:
-40 … +80 °C
-
Humidity:
45 … 75 % rel. humidity, no condensation
CAUTION !
After use and before restoring the pressure switch, please remove all
adhering media residues and clean the sensor.
This mainly applies for hazardous, caustic, toxic, carcinogenic, radiating and
similar measuring fluids.
4 Mounting
The EDS 300 can be mounted directly onto a hydraulic block via the pressure connection (G¼ A
ISO 1179-2). The connection adaptor
ZBM 14
is available as an accessory and is designed to
ensure that the display is always visible to the user.
When used in critical applications (e.g. strong vibrations or knocks) the pressure connection must
be mechanically decoupled via a Minimess hose. Mounting clamps are available as an accessory
(see point 14.2 "Accessories - for mechanical connection").
The electrical connection should be carried out by a qualified electrician according to the relevant
regulations of the country concerned (VDE 0100 in Germany). The pressure switch housing must
be earthed properly at the same time. When fitted into a hydraulic block it is sufficient if the block
is earthed via the hydraulic system. In the case of minimess hose-mounting, the housing must be
earthed separately.
Additional assembly notes which, from experience, reduce the effect of electromagnetic
interference:
•
Make line connections as short as possible.
•
Use screened lines (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.
•
Direct proximity to connecting lines of user units or electrical or electronic units causing
interference must be avoided as far as possible.
