Time setting for gradient evaluation, 1 to 100 s
Sensor evaluation to NAMUR (e.g. cable open circuit).
Only for 4 to 20 mA current signal.
Error limits for the input signal.
In the "NAMUR=Yes" operating mode, ranges 1 to 4
are assigned the limits specified by Namur NE 43 and
cannot be changed.
In the "NAMUR=No" operating mode, the error limits
can be freely selected. Here, please note that the
following applies: Range 1 < Range 2 < Range 3 <
Range 4.
Violation of these limits can be evaluated with a relay
for example ("Alarm" and "Alarm inverse" operating
mode).
