3.1 Status messages
The valve diagnostics integrated into the po-
sitioner generates classied status messages.
There are two types of status messages:
standard status messages and extended
status messages.
Standard status messages
Standard status messages contain informa-
tion on start-up as well as on operation and
the condition of the positioner.
Messages are divided into the following
main groups:
− Status
− Operation
− Hardware
− Initialization
− Data memory
− Temperature
Standard status messages are indicated in
the positioner by the codes listed in the stan-
dard positioner instructions.
Additional informative data are listed in the
subfolders of the Positioner folder:
− Operation > Process data: Information
on current process variables, condensed
state and temperature
− Settings > Positioner > Error control: In-
formation on total valve travel with con-
gurable limits
− Positioner > Start-up > Initialization: List
of initialization errors, which are also
contained in the Diagnosis folder (> Sta-
tus messages)
Extended status messages
The extended status messages are generated
from the results gained from Statistical infor-
mation (in-service monitoring) and Tests (out-
of-service diagnostics).
The messages provide information on the fol-
lowing topics to allow users to plan predic-
tive maintenance and service work:
− Air supply
− Shifting working range
− Leakage pneumatics
− Limit working range
− Observing end position
− Connection positioner - valve
− Working range
− Friction
− Actuator springs
− Inner (seat) leakage
− External leakage
− PST/FST
− On/off (not Type3730-4)
Any active diagnostic message is indicated
in the positioner by Code 79.
Extended status messages can be classied
according to the possible causes. See sec-
tion5.5 to section4.3.
