Range Extension (2.2.7.); Rate (2.3.); Transducer Selector (2.3.1.) - Siemens HydroRanger 200 HMI Operating Instructions Manual

Parameter reference
8.6 Setup (2.)
Please note that changing the Blanking cannot correct measurement problems. Ensure that
Span (2.2.2.) (Page 169) < Empty (2.2.4.) (Page 170) minus Blanking (2.2.6.).
8.6.2.7

Range extension (2.2.7.)

Allows the material level to fall below the Empty setting without reporting LOE.

This feature is useful in OCM applications where the Empty level is set to the bottom of the
weir, and above the bottom of the channel, and should be used if the surface monitored can
fall past the Empty (2.2.4.) (Page 170) level in normal operation.The value is added to Empty
(2.2.4.) (Page 170) and can be greater than the range of the transducer. If the surface
monitored can extend beyond Empty (2.2.4.) (Page 170), increase Range Extension (2.2.7.)
[in Units (2.1.1.) (Page 162)] such that Empty plus Range Extension is greater than the
transducer face to furthest surface to be monitored distance. This is often the case with OCM
when using weirs and some flumes.
