SITRANS LU01 – INSTRUCTION MANUAL

Page 89

The Process Speed setting automatically adjusts various parameters affecting the 
SITRANS LU01 response to material level changes as in the table that follows.

* Scan Delay (P727) is globally set for all Point Numbers to the value associated with the 
fastest Measurement Response (P003) selected for Point Number 1or 2. 

The following examples describe the use of SITRANS LU01 programmable features, to 
meet the needs of specific process measurement requirements. 

It is highly unlikely that your specific installation will match one of these examples 
exactly. 

However, by reviewing the example (or combination of examples) that matches your 
installation best, the relationship between SITRANS LU01 features and process 
measurement requirements may be more easily recognized.
