Page 4: For Your Safety
During work on and with the device the required personal protective equipment must always be worn. Appropriate use SU 600 Ex is a universal signal conditioning instrument and power supply unit for connection of a 4 … 20 mA/HART sensor. You can find detailed information about the area of application in chapter "Product description". -

At the same time, it can serve as power supply unit for the connected sensor.SU 600 Ex is designed for connection of any 4 … 20 mA sensor. The instrument is suitable for carrier rail, panel and surface mounting. - Page 8 Protected against solar radiation • Avoiding mechanical shock and vibration • Storage and transport Storage and transport temperature see chapter "Supplement - temperature Technical data - Ambient conditions" • Relative humidity 20 … 85 % SU 600 Ex • 4 … 20 mA signal conditioning instrument...

Page 9: Mounting
If the instrument is mounted via the screws or carrier rail, it must always be inside a switching cabinet or protective case. A SU 600 Ex is an auxiliary, intrinsically safe instrument and may not be installed in explosion-endangered areas. - Page 10 Metal strap 2 Covering slide switch active-passive Carrier rail mounting 1. Place the adapter plate [1] to the rear of SU 600 Ex (spring of the adapter plate downward) and fasten the plate with screw [2] (M4 x 6). 2. PlaceSU 600 Ex against the carrier rail [3] from below and push the instrument upward until it snaps in.

Page 12: Connecting To Power Supply
If potential equalisation currents are expected, the screen connec- tion on the side of SU 600 Ex must be made via a ceramic capacitor (e. g. 1 nF, 1500 V). The low frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains. - Page 13 2. Lead the sensor cable towards the front and out of the Ex sepa- rating chamber 3. Push the Ex separating chamber towards the front until you hear it snap in SU 600 Ex • 4 … 20 mA signal conditioning instrument...

Page 14: Wiring Plan
In passive mode the sensors are not powered, only the measured value is transmitted. This input is for connection of transmitters with their own separate voltage supply (sensors in four-wire ver- sion). The SU 600 Ex can be also looped into the existing circuit like a normal ammeter. The position of the slide switch also influences the preconditions for Ex implementation. Take note of the type approval certificate or the... -

– Current output – Integration time – Offset correction • [+/-] key: – Change value of the parameters By pushing the [+/-] key, you change the individual parameters of the selected function. In this phase, the processed parameter is flashing. SU 600 Ex • 4 … 20 mA signal conditioning instrument... -
Page 16: Setup Steps
To clearly denote the measuring unit, the supplied labels can be inserted in the cover. In case several SU 600 Ex are used, each measurement loop should be clearly labelled. Switch-on phase After being switched on, SU 600 Ex first of all carries out a short self- check. - Page 17 [1] or [2], enter the switching points for ON or OFF and save your settings. If necessary, proceed in the same way with relay 2 (position [3] or [4]). SU 600 Ex • 4 … 20 mA signal conditioning instrument...

With a reset, all values set by the user will be lost and are reset to factory settings. → Interrupt the power supply of SU 600 Ex. Push the [+/-] keys simultaneously and hold them while you switch on the power supply. The display shows "RES" and the default settings will be restored. - Page 20 0 - 20 = 0 … 20 mA • 4 - 20 = 4 … 20 mA 2. Save the value by pushing [+/-] simultaneously SU 600 Ex requires for scaling of the indication, the adjustment of the filling quantities for 0 % and 100 %. The vessel must neither be filled nor emptied. Scaled indication at 0 % 1.
