1 Safety
1.1 General safety instructions
– Only use the product in original status without unauthorised modifications.
– Only use the product if it is in perfect technical condition.
– Observe labelling on the product.
– Condensation, oil mist, foreign matter and other contaminants in the com­
pressed air can damage the product. Only use media in accordance with the
specifications è Technical data.
– This product can generate high frequency interference, which may make it
necessary to implement interference suppression measures in residential
areas.
1.2 Intended use
The SDE5 is intended for pressure monitoring of gaseous media in piping systems
or terminal equipment in industry.
1.3 Training of qualified personnel
– Installation, commissioning, maintenance and disassembly should only be
conducted by qualified personnel.
1.4 Area of application and approval
The information in this section, in combination with the UL marking on the
product, must be observed in order to ensure compliance with the certification
conditions of Underwriters Laboratories Inc. (UL) for USA and Canada. Observe
the following information in English by UL:
In determining the acceptability of the combination, the following details should
be examined:
– The mounting suitability shall be determined in the end­use.
– These devices shall be mounted in an enclosure having adequate strength
and thickness.
– Devices should be used within its recognized ratings as specified under sec­
tion RATINGS.
– Devices have to be supplied from:
– A Class 2 power source or Class 2 transformer in accordance with UL1310
or UL1585, or
– An isolating device such that the maximum open circuit voltage potential
available to the circuit is not more than 30 Vdc and the current is limited
to a value not exceeding 8 amperes measured after 1 minute of opera­
tion, or
– A suitable isolating source in conjunction with a fuse in accordance with
UL248. The fuse shall be rated max. 3.3 A and be installed in the 30 Vdc
power supply to the device in order to limit the available current.
Note that, when more than one power supply or isolating device is used, connec­
tion in parallel is not permitted.
– The devices have not been investigated for field­wiring.
– The suitability should be determined in the end­use application.

4.2 Function
4.2.1 Functional principle
The SDE5 converts pneumatic pressure values into a voltage proportional to the
pressure. Depending on the design of the pressure sensor, the voltage signal is
converted into a digital switching signal (SDE5­...­P­.../SDE5­...­N­..) or amplified
for an analogue output (SDE5­...­NF­...­V).
