3.2 Principle of operation

Area of application
30653-EN-050803
SU 600 Ex - 4 ... 20 mA signal conditioning 7
SU 600 Ex 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
Product description
supply unit for connected sensors.SU 600 Ex is designed for connection of an individual 4 … 20 mA sensor. The instrument is suitable for carrier rail, panel and surface mounting.
Physical principle
Power supply
Packaging
SU 600 Ex 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 Ex is carried out via the integrated keys and a 16-step function switch.

3.4 Storage and transport

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 environ-
ment-friendly, recyclable cardboard. For special versions PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.

4 Mounting

4.1 General instructions

Mounting
Installation location
Carrier rail mounting
You can mount theSU 600 Ex signal conditioning instrument onto a carrier rail 35x7.5 acc. to DIN EN 50022, or directly on the wall by means of the three screws or in a front panel or door of a switching cabinet.
Note:
Before mountingSU 600 Ex , set the requested mode of the measuring data input. With a slide switch on the rear of the instrument you can choose between active and passive current input (see also chapter " Connecting to power supply "). After mounting the instrument, the slide switch is no longer accessible.
