Activating the self-test (function test)
"
Caution!
Make sure that you do not accidentally activate any processes with the self-test!
This could result, for example, in overflowing of the tank.
!
Note!
The self-test simulates switching states (probe not covered, probe covered).
This allows you to check if the connected devices are activated correctly.
To carry out a self-test, proceed as follows:
1.
Turn the function switch to position 6.
2.
Press the "+" and "–" keys simultaneously for at least two seconds.
The self-test is active when the green LED 5 flashes.
The green operational LED 1 is off.
3.
After approx. 20 seconds, the test is completed. This is indicated by the lighting up of the
operational LED 1.
You have now carried out the self-test and can turn the function switch back to position 1
(operation).
