Commissioning - Siemens SITRANS TH100 Operating Instructions Manual

Commissioning

Missing type of protection
If the transmitter is not operated with an intrinsically-safe power supply, the type of
protection "Intrinsic safety" is no longer guaranteed and the intrinsically-safe approval may
be revoked.
Permanently erase, therefore, the irrelevant types of protection on the nameplate before
commissioning to ensure that erroneous deployment is avoided.
Procedure
1. Program the transmitter's operating data according to the actual requirements.
2. Assemble the transmitter.
3. Connect the sensor to the power supply, see Chapter Connecting (Page 19).
4. Turn on the auxiliary power supply.
5. Wait about 10 seconds. After this start-up time the transmitter is operational.

WARNING
If applicable, enter the changed operating data on the additional plate on the enclosure.
Note
Warming-up
To obtain exact measured values, the transmitter needs to be allowed to warm up for five
minutes or so after the power supply has been switched on.
