CURRENT SPAN
Use this function to define the current span. You can configure the current
output either in accordance with the NAMUR recommendation (max. 20.5 mA)
or for a maximum drive of 25 mA.
Options:
OFF
4-20 mA (25 mA)
4-20 mA (25 mA) HART
4-20 mA NAMUR
4-20 mA HART NAMUR
4-20 mA US
4-20 mA HART US
Factory setting:
4-20 mA (25 mA) HART
Current span, work range and signal on alarm level
A = Current span (option)
➀
= Work range
➁
= Lower signal on alarm level
➂
= Upper signal on alarm level
➃
= Scaled full scale value
Q = Flow
!
Note!
• If the measured value exceeds the measuring range (as defined in the
function VALUE 20 mA, Page 98) a notice message is generated
(#351, current span)
• The current output's response to faults is defined in the central FAILSAFE
MODE function (Page 112).
