4.9 Commissioning
Before switching on the measuring system, the following checks should be carried out
again:
•
Check the electrical connections and terminal assignments.
•
Compare the data on the nameplate with the local mains voltage and frequency.
•
Does the direction of the arrow on the nameplate (sensor) agree with the actual
direction of flow in the piping?
If the results of these checks are satisfactory, switch on the supply voltage. The unit is
now ready for operation. After switching on, the system performs various self-test
routines. During this procedure the following sequence of messages appears on the
display:
