6 Setup with the integrated display and adjustment unit
SU 600 • 4 … 20 mA signal conditioning instrument
30652-EN-150129
can be displayed. Select position [
5
] of the function switch, place
the decimal point in the required position and save your settings.
2. Now select position [
6
] or [
7
] on the function switch, enter the
requested values for 100 % or 0 % and save your settings.
To suppress fluctuations in the measured value display, e.g. caused
by an agitated product surface, an integration time can be set. This
time can be between 0 and 250 seconds. Remember that the reaction
time of the entire measurement will then be longer and the sensor will
react to measured value changes with a delay. In general, a period of
a few seconds is sufficient to smooth the measured value display.

Now select position [
9
] on the function switch, enter the request-
ed value and save your settings
The characteristics of the current output can be switched over from
4 … 20 mA to 0 … 20 mA.
→
Now select position [
8
] on the function switch, adjust the re-
quested characteristics curve and save your settings
To check if the settings ofSU 600 are correct, the simulation mode
can be used. Any individual measured value can be simulated and
e.g. the correct behaviour of the relays and the connected instruments
can be checked.
Switching over between the functions "
OPERATE
" and "
Simulation
" is
done by pushing the [
+/-
] keys for at least 3 seconds. In the simula-
tion mode, the set value flashes on the display. The simulation can be
switched off by pushing both keys again for approx. 3 seconds. If no
key is pushed, the display switches automatically over to "
OPERATE
"
after approx. 60 minutes and the simulation is terminated.
→
To start simulation, push the [
+/-
] keys simultaneously until the
displayed value starts flashing (approx. 3 seconds). By pushing
either of the [
+/-
] keys, you can set the requested simulation
value and carry out your check.
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. Push the [
+/-
] keys simul-
taneously and hold them while you switch on the power supply.
The display shows "
RES
" and the default settings will be restored.
