Function Manual, 06/2018, A5E39931813-AB
Parameter
Description
Upper range
Upper standard volume
value standard
flow value that is map‐
volume flow
ped to the upper nomi‐
nal range boundary se‐
lected by Current mode
(9106). Applicable if
Process value (9102) =
27.
Lower range
Lower standard volume
value standard
flow value that is map‐
volume flow
ped to the lower nomi‐
nal range boundary se‐
lected by Current mode
(9106). Applicable if
Process value (9102) =
27.
Upper range
Upper current value
value current
that is mapped to the
upper nominal range
boundary selected by
Current mode (9106).
Applicable if Process
value (9102) = 25 or 26.
Lower range
Lower current value
value current
that is mapped to the
lower nominal range
boundary selected by
Current mode (9106).
Applicable if Process
value (9102) = 25 or 26.
Damping value
Time constant of damp‐
ing filter for current out‐
put signal.
Filter-safe acti‐
Fail-safe activation con‐
vation condition
dition.
Fail-safe min.
Minimum time the out‐
time
put stays in fail-safe be‐
havior.
Fail-safe behav‐
Current output reaction
ior
in case of a fault.
