Breakdown information to NAMUR NE43:
The information is created when the measuring information is invalid or not present anymore and gives a complete listing
of all errors occurring in the measuring system.
Under ranging Standard linear drop to 3.8
Over ranging Standard linear rise to 20.5
Failure, e. g. sensor break; sensor short
circuit
To NAMUR NE43 ≤ 3.6 mA ("low") or ≥ 21 mA ("high")
can be selected
1)
1) The high alarm is adjustable between 21.6 mA and 23 mA allowing for flexibility when working with the
requirements of most control systems.
