SU 600 • 4 … 20 mA signal conditioning instrument
30652-EN-150129
3.2 Principle of operation
SU 600 is a universal single signal conditioning instrument with inte-
grated level switches and display for continuous sensors. At the same
time, it can serve as power supply unit for the connected sensor.SU
600 is designed for connection of any 4 … 20 mA sensor. The instru-
ment is suitable for carrier rail, panel and surface mounting.
The SU 600 signal conditioning instrument can power connected
sensors and process their measurement signals. The requested
measured variable is shown on the display and also outputted to the
integrated current output for further processing.The measurement
signal can thus be transferred to a remote indication or a superor-
dinate control system.Two level relays for control of pumps or other
devices are also integrated.
Wide-range power supply unit with 20 … 253 V AC/DC for worldwide
use.
Detailed information about the power supply can be found in chapter
"Technicaldata".
3.3 Operation
The adjustment of SU 600 is carried out via the integrated keys and a
16-step function switch.
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
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.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation

4.1 General instructions
The instrument is designed for recessed installation in a front panel,
housing front plate or a switching cabinet door.The required cut-out
is 92 x 92 mm (3.63 x 3.63 in) according to EN 60529. When installed
correctly, protection rating IP 40 is guaranteed. As an alternative,
the instrument can be mounted into a switching cabinet or housing
bymeansofthreescrews(xedwithscrewsonrearofhousing).
A mounting adapter for carrier rail mounting is optionally avail-
able in the scope of delivery (top hat rail 35 x 7.5 according to DIN
EN 50022/60715).
Information:
If the instrument is mounted via the screws or carrier rail, it must
always be inside a switching cabinet or protective case.
4.2 Mounting instructions
1. Makesurethatthecutoutrequiredforinstallationhasasizeof
92 x 92 mm (3.63 x 3.63 in). The required installation depth is min.
90 mm (3.54 in).
2. Remove the pluggable terminal strips from the top and bottom.
3. Screw the threaded pin [3] into the rear of the instrument and
tighten with a screwdriver.
4. Insert the instrument from the front into the front panel [1].
5. Place the clamping strap [2] from the back over the pin [3] and
