4.5.3 Online diagnosis

While the positioner is in operation, some important values and

parameters are monitored on a continuous basis. In “Configuration”

mode, you can configure this monitoring in such a way that the fault

message output is activated when a certain event occurs, such as e.g.

when a limit is exceeded.
Table 4-2, page 133, shows which events can activate the fault

message output and the alarm outputs, how the parameters need to be

set for this event to be monitored, when the fault messages disappears

again and what the possible causes of the malfunction are.
In automatic and manual mode, the display shows what triggered the

fault message when the fault message output reacts. The two numbers

at the bottom left indicate the relevant error code. If several triggers

occur simultaneously, they are display in succession cyclically. The

device status that also includes all fault messages, can be called using

command #48 via HART.
The parameters of the extended diagnostics allow error messages to

be displayed in one, two or three levels. In addition to the fault

message output, alarm outputs 1 and 2 are then used. For this

purpose, para-

meter 51.XDIAG needs to be set according to the following table:
