Signal - Low/High The low and high signal defines at what input values the valve is fully
open or fully closed. The low signal value must always be lower than
the high signal value. The ValVue software identifies which value rep-
resents closed and which represents open from the configuration
data.
The values will typically be 4 and 20 mA but may be any values
between 3.8 and 22 mA. If the valve is to be split ranged, (low) values
of 3.8 to 14 and (high) values of 10 to 20.2 may be entered. There
must be at least 5 mA difference between the low and high values.
These entries are the proper method of split ranging the SVI (rather
than with a custom characterization curve).
Changing the signal low and high values is not allowed on an SVI2-1.
