Parameter Description
Upper range Upper mass flow value
value mass flow that is mapped to the
upper nominal range
boundary selected by
Frequency value high
(9435). Applicable if
Process value (9404) =
0.
Lower range Lower mass flow value
value mass flow that is mapped to the
lower nominal range
boundary selected by
Frequency value low
(9437). Applicable if
Process value (9404) =
0.
Upper range Upper process density
value density value that is mapped to
the upper nominal
range boundary selec‐
ted by Frequency value
high (9435). Applicable
if Process value (9404)
= 2.
Lower range Lower process density
value density value that is mapped to
the lower nominal
range boundary selec‐
ted by Frequency value
low (9437). Applicable
if Process value (9404)
= 2.
Lower range Upper process medium
value tempera‐ temperature value that
ture is mapped to the upper
nominal range boun‐
dary selected by Fre‐
quency value high
(9435). Applicable if
Process value (9404) =
3.
Lower range Lower process medium
value tempera‐ value that is mapped to
ture the lower nominal
range boundary selec‐
ted by Frequency value
low (9437). Applicable
if Process value (9404)
= 3.
