1. Functions of the EDS 1700
l Measured value display of the current pressure in bar, psi or in a scale
defined by the user.
l Switches the 4 relay outputs according to the pressure and the pre-set
switching points and hystereses or switch-back points.
l Records the maximum pressure since the unit was switched on.
l Menu for basic setting (adaptation of the EDS 1700 to the particular
application).
l Two different types of programming enable.
l Optional mounting position (pressure connection from above or below).
2. Mounting
The EDS 1700 is mounted via the 4 mounting holes in the rear panel of the
housing. The pressure connection must be via Minimess line for mechanical
decoupling. In critical applications (e.g. strong vibrations or knocks), the
EDS 1700 must be mounted on rubber buffers (DIN vibration mounts).
A mounting kit is available on request (see "Other Accessories).
The EDS 1700 must not be installed using rigid piping.
When supplied the pressure connection is accessible from the bottom and the
electrical connection is accessible from the top. The front panel can be turned
through 180° so that the electrical connection can be made from underneath
and the pressure connection can be made from the top.
The electrical connection must be carried out by a qualified electrician
according to the relevant regulations of the country concerned (VDE 0100 in
Germany). When connecting the analogue output, screened lines must always
be used (e.g. LIYCY 4 x 0.5 mm²). The pressure switch housing must be
earthed via the -connection (next to the terminal strip).
Additional assembly notes which have been shown to reduce the effect of
electromagnetic interference:
l Make line connections as short as possible.
l Use screened lines.
l The cable screening must be fitted by qualified personnel subject to the
ambient conditions and with the aim of suppressing interference.
l Direct proximity to connecting lines of user units or electrical or electronic
units causing interference must be avoided as far as possible.
