volume flow ped to the lower nomi‐
nal range boundary se‐
lected by Frequency
value low (8937). Appli‐
cable if Process value
(8904) = 27.

value current that is mapped to the
upper nominal range
boundary selected by
Frequency value high
(8935). Applicable if
Process value (8904) =
25 or 26.
Lower range Lower current value
value current that is mapped to the
lower nominal range
boundary selected by
Frequency value low
(8937). Applicable if
Process value (8904) =

Damping value Time constant of damp‐
ing filter for frequency
output signal.
Fail-safe behav‐ Frequency output reac‐
ior tion in case of a fault.
Fail-safe value Output value in case of
