6 Setup with the integrated display and adjustment unit
SU 600 Ex • 4 … 20 mA signal conditioning instrument
30653-EN-150129
1. Select the following functions with the rotary switch.
2. Push one of the two [
+/-
] adjustment keys, the digital indication
flashes (if the rotary switch is set to "
OPERATE
", the [
+/-
] keys are
inoperable)
3. Adjust the requested value with the [
+/-
] keys. If you hold the key
pushed, the digital indication changes the value more quickly.
4. Save your settings by pushing the [
+/-
] keys simultaneously
1. Set the function switch to position [
8
]. Select with the [
+/-
] keys
the measured value output 4 … 20 mA or 0 … 20 mA. For this
example, choose 4 - 20.
The displayed numbers have the following meanings:
•
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.
1. Set the function switch to position [
7
] (display min.)
2. Set the value to 50 via the [
+/-
] keys
3. Save the value by pushing both keys simultaneously
1. Set the function switch to position [
6
] (display max.)
2. Set the value to 2650 via the [
+/-
] keys
3. Save the value by pushing both keys simultaneously
Since the range of the example tank is between 50 l and 2650 l, you
need all 4 decimal places for the digital indication.
1. Set the function switch to position [
5
] (Decimal Point)
2. By pushing the [
+/-
] keys, you move the decimal point
3. Save the value by pushing both keys simultaneously
•
Set the function switch to position [
1
] (relay 1 on). For the given
example, select the value 90.0 (90.0 %) with the [
+/-
] keys. The
internal relay 1 then switches on when this value is reached. Save
the value by pushing the two keys simultaneously.
•
Set the function switch to position [
2
] (relay 1 off). Select the
value 10.0 (10.0 %) with the [
+/-
] keys. The internal relay 1 then
switches off when the value falls below this value. The respective
relay control lamp lights when the relay is energized. If the switch-
ing points are too close together (< 0.1 %), the appropriate LED
flashes. The relay takes on the safe condition. In mode "
OPERATE
" an error message is outputted on the display.
•
If you want to control additional relays, proceed in the same way,
as with relay 1. The switch positions for setting the respective
relays are stated in the list of the function switch under "Setup
procedure".
