Parameter Description
Upper range Upper process viscosi‐
value viscosity ty value that is mapped
to the upper nominal
range boundary selec‐
ted by Frequency value
high (9435). Applicable
if Process value (9404)
= 21 or 29.
Lower range Lower process viscosi‐
value viscosity ty value that is mapped
to the lower nominal
range boundary selec‐
ted by Frequency value
low (9437). Applicable
if Process value (9404)
= 21 or 29.
Damping filter Time constant of damp‐
ing filter for frequency
output signal.
Fail-safe activa‐ Fail-safe activation con‐
tion condition dition.
Fail-safe min. Minimum time the out‐
time put stays in fail-safe be‐
havior.
Fail-safe behav‐ Frequency output reac‐
ior tion in case of a fault.
Fail-safe value Output value in case of
a fault and when Fail-
safe behavior (9439) is
configured to 4.
Forced value Forced value when
forcing is active.
