Generally the relay control lamp shows the activated
(energized) condition of the relay
-
A dark relay control lamp means that the relay is deenergised
(transistor blocks)
A potentiometer for switching point adaptation is located on the front
plate of the signal conditioning instrument. With this potentiometer you
can adapt the measuring system to the conductivity of the product.
On top to the side (covered when mounted) there is a DIL switch block
with four switches. The individual switches are assigned as follows:
l
1 - A/B mode
-
A - Max. detection or overflow protection
-
B - Min. detection or dry run detection
l
2 - Integration time 2 s
l
3 - Integration time 6 s
l
4 - Integration time 12 s
With switch 1 you can adjust the mode (A - overfill protection or B - dry
run protection).

Fig. 11: DIL switch block
In the example (see previous illustration), mode A (max. detection or
overfill protection) is selected (switch 1). The integration time is set to 8
seconds (switch 2, 3 and 4).
You can adjust the integration time accordingly with switch 2, 3 and 4.
The time periods of the activated time switches add up. The set time
applies to the switch on as well as the switch off delay.
