Commissioning

8.2 Recommendation for the selection of parameters

Note
The first settings undertaken after commissioning should be regularly checked and corrected
if necessary. This is the case, if:
• Experience values or measured values indicate defects, which could possibly indicate
• After a repair it is identified that the report of a defect has occurred too early.
8.2 Recommendation for the selection of parameters
8.2.1

Preparation

Note
After turning on the power supply, the device performs a self-test "SELF Test". After
completion of the self-test, approximately 5 seconds, the device is ready to use. Acoustic
channel 1 "1/SO1" is shown in the digital display.
Procedure
1. Turn on the power supply.
2. Commission the pump(s).
3. Wait until the normal delivery rate, discharge pressure and media temperature have been
reached.
4. For each measurement channel used, set the parameters P.1 to P.4 associated with the
measurement channel to the value "on L" or "on H". Leave measurement channels not
used on "oFF".
5. After around two minutes, read off the measured values for each acoustic channel. The
subsequent procedure depends on the measured values read here. These are described
in the following sections.
The following can be determined from the measured values read off:
● All measured values are similar. Then the pump is in order and you may continue with the
● There are great differences between the measured values of the acoustic channels. This
