Introduction to commissioning

Following commissioning, the transmitter is immediately ready for use.
To obtain stable measured values, the transmitter needs to be allowed to warm up for five minutes or so after the power
supply is switched on. Upon switch-on, the transmitter goes through an initialization routine (display at the end: "Init done").
If the transmitter initialization routine does not complete, check the auxiliary power.
The operating data must correspond to the values specified on the nameplate. If you switch on the auxiliary power, the
transmitter will operate.
The following commissioning cases are typical examples. Configurations different from those listed here may be meaningful
depending on the system configuration.
