Description
The option of editing the operating parameters is locked after entering a 4-digit
digital sequence (limit value code).
This lock is indicated on the display with the "key" symbol.
If the limit value code function is activated, only the configuration of the limit val-
ues is permitted. All other operating parameters cannot be modified.

• Off = relays de-energize in the event of an error or device malfunction
• On = relays energize in the event of an error or device malfunction
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 spec-
ified by Namur NE 43 and cannot be changed.
In the "NAMUR=No" operating mode, the error limits can be freely selected.
