Installation
Installed as pressure gauge
2.1.
The EDS 601 can be installed directly into the hydraulic system via the G ¼"
threaded connection or an adapter. Depending on the type of connection, the
sealing should be to DIN 3852 or DIN 16288. The torque should be within the
range 20..30 Nm. (Where adapted for G½": 45..50 Nm).
Installed as front panel measuring unit
2.2.
The unit is installed in a front panel cut-out of 68.5 x 68.5 mm. The unit is
secured with clamps from the mounting set, which can be ordered separately.
For mechanical de-coupling the hydraulic connection must be via a standard
small bore instrument hose. The sealing can be by means of an O-ring or a
metallic soft seal to DIN 3852. The torque should be within the range 20..30 Nm.
Note:
When installed as a front panel unit a rigid hydraulic connection
must not be used.
Making the electrical connection
2.3.
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 electronic pressure switches EDS 601 carry the
conformity is available on request.
The EMC-standards EN 61000-6-1 / 2 / 3 / 4 apply.
The requirements of the standards are fulfilled only if the pressure switch
housing is earthed correctly by qualified personnel. If the pressure switch is
mounted inline, it is sufficient if the pipe is earthed via the hydraulic system. In
the case of hose-mounting, the housing must be earthed separately via the PE
connection of the 4-pole plug.
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 mm
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.
