Step 2: Validate values using the "Func‐
tional Safety" wizard
Values for the validation Enter validated value
①
Device identification data (if Function‐
al Safety is enabled via remote oper‐
ation)
● Long tag
● Product name
● Serial number
The values can be found on the
nameplate of the device and are
displayed via the wizard.
②
Safety-related parameters
S1 Primary variable Pressure (the parameter cannot be
changed)
S2 Damping value 0.01 s ... 100 s in increments of
0.01 s
S3 Lower range value The value is within the measuring
limits. You can find information on
the nameplate of the device or in
the section Technical data
(Page 199)
S4 Upper range value The value is within the measuring
limits. You can find information on
the nameplate of the device or in
the section Technical data
(Page 199)
S5 Application
● Linear, proportional to pressure
(PRESS).
● Linear, proportional to level
(LEVEL).
● Proportional to flow rate, two-
step linear up to the application
point (VSLN2 or MSLN2).
S6 Overload behavior Alarm or warning
S7 Upper saturation limit Between 20 mA and the upper fault
current
③
Fingerprint (only if Functional Securi‐
ty is enabled via remote operation)
The value is displayed using the
