9 Status and diagnostic alarms
The Type 3730-5 Positioner contains inte
-
grated diagnostics to generate classified sta
-
tus and diagnostic alarms.
There are two different types of on-board di
-
agnostics available: the standard integrated
diagnostics (EXPERT) and the optional ex
-
tended EXPERT
+
diagnostics.
Due to the numerous diagnostic functions
provided, the positioner generates classified
status alarms and diagnostic alarms.
9.1 Standard EXPERT diagnostics
The standard EXPERT diagnostics provides
information about positioner states such as
operating hours counter, process monitor-
ing, number of zero calibrations and
initializations, total valve travel, tempera-
ture, initialization diagnostics, zero/control
loop errors, logging of the last 30 alarms,
etc.
In addition, the standard EXPERT diagnostics
generates diagnostic and status alarms
which allow faults to be pinpointed quickly
when a fault occurs. Besides being dis
-
played on the positioner display, the classi
-
fied alarms are also available over the de
-
vice description (DD).
Alarms are classified in the following main
groups:
