Siemens SITRANS LR580 User Manual

Note
Par
ameter "Upper range value" is limited when PV set to Level or Space
When PV is set to Level or Space, the setting for parameter "Upper range value" is limited by the
setting for parameter "Upper level point".
• If desired setting for parameter "Upper range value" is greater than the current setting in
parameter "Upper level point", it is necessary to 󹪝rst set parameter "Upper level point" to a
value equal to, or greater than the desired value for parameter "Upper range value".
Note
"Upper range value" (URV) versus "Upper scaling point"
• When parameter "Upper range value" is set within the "Quick commissioning wizard", it
automatically sets the "Upper scaling point" to the same value.
• Setting a value for either parameter outside of the wizard, will not automatically adjust the
other value.
Note
Changing cus
tom units
If a change is made to custom units, be sure to rescale the output, as rescaling for custom units
is not handled automatically by the device.
• To rescale output, use parameters "Upper range value" and "Upper scaling point".
9.2.4.6 Lower saturation limit (2.4.6)
Se
ts lower limit for saturation range (4 mA to parameter "Lower saturation limit"), past which the
loop current cannot decrease.
Setting 3.55 to 4 mA
Default 3.8 mA
9.2.4.7 Upper saturation limit (2.4.7)
Sets upper limit for saturation range (20 mA to parameter "Upper saturation limit"), past which
the loop current cannot increase.
Setting 20 to 22.8 mA
Default 20.5 mA
9.2.4.8 Lower fault current (2.4.8)
Se
ts Lower fault current in Non-safety mode.
Setting 3.55 to 4.0 mA
Default 3.55 mA
