• The manufacturer assumes no liability or warranty for any consequences
caused by tampering with the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the
product must be carried out by qualified personnel authorised by the machine
operator.
• Protect units and cables against damage.
• Avoid static and dynamic overpressure exceeding the given overload pressure
(→ Technical data) by taking appropriate measures.
• The indicated bursting pressure (→ Technical data) must not be exceeded.
Even if the bursting pressure is exceeded only for a short time, the unit may be
destroyed. CAUTION: risk of injury!
• For submersible pressure transmitters PS3xxA: Adhere to the remarks for safe
use in hazardous areas (→ ATEX operating instructions).
3 Items supplied
For the measuring range and the cable length please refer to the data sheet of the
corresponding submersible pressure transmitter.
The submersible pressure transmitters PS3xxA are approved for use in hazardous
areas.
The following components are available as accessories (to be ordered separately):
Order no.
Cable clamp fastener for placing the submersible pressure transmitter
in the tank*
E30399
Filter element for fixing on the capillary ventilation* E30400
Splitter box for electrical connection* E30401
Additional weight to increase the dead weight of the unit E30402
*CAUTION: use only outside the hazardous area.

4 Functions and features
The unit detects the hydrostatic pressure and converts it into an analogue output
signal. The output signal changes in proportion with the level of the tank.
Applications
• Liquids.
• Tanks, containers, wells, streaming water, drill holes, wastewater plants.
Pressure Equipment Directive (PED):
The units comply with the Pressure Equipment Directive and are designed
and manufactured for group 2 fluids in accordance with the sound
engineering practice. Use of group 1 fluids on request!
5 Installation
►Place the unit in the tank such that it is as close as possible to the tank bottom
(→ Fig. 1). For fixing with cable clamp fastener → Fig. 2.

► For viscous media: unscrew and remove the protective cap (A).
► In order to prevent or reduce oscillating movements of the unit:
unscrew the protective cap (A), screw the additional weight (order no.
E30402) to the unit.
The unit operates on the principle of relative pressure. A capillary tube ensures
pressure compensation. It is inserted through the connection cable.
►Make sure that the capillary tube is not blocked. If necessary, install a filter
element (order no. E30400). Or use the splitter box with ventilation (order no.
E30401) for the electrical connection.

UK
In wet environments there is the risk that water penetrates into the unit
through the capillary tube and causes damage to it. In this case use the
filter element or the splitter box with ventilation.
The filter element and the splitter box are only allowed for use outside
hazardous areas.
5.1 Requirements for the mounting location
(applies to PS3xxA)
Strong electromagnetic fields in the frequency range < 2.7 GHz may lead to
increased measurement errors up to 1 % of the span.Do not install the units near
strong sources of electromagnetic interference (e.g. transmitters, radio equipment)
or, if necessary, use a sheath current filter.
6 Electrical connection
The unit must be connected by a qualified electrician.
The national and international regulations for the installation of electrical
equipment must be adhered to.
Voltage supply to EN 50178, SELV, PELV.
For submersible pressure transmitters PS3xxA: For use in hazardous
areas: connection to intrinsically safe supply isolators (Ex ia).
►Disconnect power.

7 Maintenance, repair and disposal
The unit has to be included in the recurrent pressure test of the tank.
Only the manufacturer is allowed to repair the unit.
After use dispose of the unit in an environmentally friendly way in accordance with
the applicable national regulations.
