Read only
Current signal pressure [bar]
d9 Flow rate
Read only
Current valve ow rate
Note: – – – – appears on the display when the ow rate calcula-
tion is not active or has failed.
d10 Differential pressure
Read only
Current differential pressure [bar]
d11* Direction of action (ac-
tuator)
[-/-], SA, DA, ELSE,
ESC

SA: Single-acting
DA: Double-acting
ELSE: Other
Diagnostic parameters h
h0* Initialization including
valve signature
No, [YES], ESC
Initialization with [YES] or without [No] plotting the valve signature
The valve signature involves the signal pressure p
out
being plotted
in relation to the valve position.
Regardless of the adjusted settings, the valve signature is recorded
automatically when initializing a positioner that has not yet been
initialized (e.g. after initialization was reset (Code36 - Std and
Code36 - DS)), after each further initialization if the settings for
'Initialization mode', 'Pin position', 'Direction of action', 'Pressure
limit', 'Proportional-action coefcient Kp level' or 'Derivative-action
time Tv level' were changed, and when the switch position (ATO/
ATC) was changed.
Note: The valve signature is required to perform diagnostic func-
tions.
