2.1 Authorised personnel
All operations described in this operating instructions
manual must be carried out only by trained specialist
personnel authorised by the operator. For safety and
warranty reasons, any internal work on the instruments
must be carried out only by personnel authorised by the
manufacturer.
2.2 Appropriate use
SU 600 is a universal signal conditioning instrument and
power supply unit for connection of a 4 … 20 mA/HART
sensor.
2.3 Warning about misuse
Inappropriate or incorrect use of the instrument can give
rise to application-specific hazards, e.g. vessel overfill or
damage to system components through incorrect
mounting or adjustment.
2.4 General safety instructions
SU 600 is a high-tech instrument requiring the strict
observance of standard regulations and guidelines. The
user must take note of the safety instructions in this
operating instructions manual, the country-specific
installation standards (e.g. the VDE regulations in
Germany) as well as all prevailing safety regulations and
accident prevention rules.
2.5 CE conformity
SU 600 is in CE conformity with EMC (89/336/EWG) and
NSR (73/23/EWG).
6 SU 600 - 4 … 20 mA signal conditioning
30652-EN-050525
For your safety
Conformity has been judged acc. to the following
standards:
l EMC:
- Emission EN 61326: 1997 (class A)
- Susceptibility EN 61326: 1997/A1: 1998
l NSR: EN 61010-1: 2001
SU 600 is designed for use in an industrial environment.
Nevertheless, electromagnetic interference from elect-
rical conductors and radiated emissions must be taken
into account, as is usual with a class A instrument acc. to
EN 61326. If SU 600 is used in a different environment,
the electromagnetic compatibility to other instruments
must be ensured by suitable measures.

3.2 Principle of operation
Product description
Area of application
Physical principle
Power supply
SU 600 is a universal single signal conditioning
instrument with integrated level switches and display for
continuously measuring sensors. At the same time, it
can serve as power supply unit for connected sensors.
SU 600 is designed for connection of an individual
4 … 20 mA sensor. The instrument is suitable for carrier
rail, panel and surface mounting.
SU 600 signal conditioning instrument can power the
connected sensor and also evaluate its measurement
signals. The requested parameter is indicated in the
display and, in addition, outputted to the integrated
current output for further processing. Hence the measuring signal can be transmitted to a remote display or a
connected control system. In addition, two level relays
for control of pumps or other actuators are integrated.
Wide-range power supply unit with 20 … 253 VAC/DC
for world-wide use.
You will find detailed information on the power supply in
the "Technical data" in the "Supplement".
3.3 Adjustment
The adjustment of SU 600 is carried out via the
integrated keys and a 16-step function switch.
3.4 Storage and transport
Packaging

Your instrument was protected by packaging during
transport. Its capacity to handle normal loads during
transport is assured by a test acc. to DIN EN 24180.
The packaging of standard instruments consists of
environment-friendly, recyclable cardboard. For special
versions PE foam or PE foil is also used. Dispose of the
packaging material via specialised recycling companies.
