8.3.2.22 '50.XDIAG' Activation of extended diagnostics
Use this parameter to activate the extended diagnostics functions and simultaneously the
online diagnostics. You also define which maintenance level is to be signaled. Maintenance
levels in the order of increasing importance are maintenance required, maintenance
demanded, maintenance alarm. At the factory, extended diagnostics are deactivated. 'XDIAG'
parameter is set to 'OFF'. To activate extended diagnostics, there are three modes available:
● On1: Extended diagnostics is activated. Threshold 3 messages will be output via the error
message output. Single stage message (maintenance alarm).
● On2: Extended diagnostics is activated. Threshold 2 messages will be activated via alarm
output 2. Threshold 3 messages will also be output via the error message output. Two-stage
message (maintenance demanded, maintenance alarm).
● On3: Extended diagnostics is activated. Threshold 1 messages will be activated via alarm
output 1. Threshold 2 messages will be activated via alarm output 2. Threshold 3 messages
will also be output via the error message output. Three-stage message (maintenance
required, maintenance demanded, maintenance alarm).
Note
Activation of extended diagnostics
Please note that the parameters of extended diagnostics from 'A.\\PST' to 'P.\\PAVG' will
only be shown in the display following selection of one of the modes 'On1' to 'On3'.
In the factory settings, the 'A.\\PST' to 'P.\\PAVG' parameters are deactivated by default.
'XDIAG' parameter is set to 'OFF'. The corresponding parameters are only displayed after
you have activated the appropriate menu item with 'On'.
Note
Cancellation of messages
If a threshold is exceeded or fallen below, the positioner outputs a message in the form of
an error code and a column in the display. The message is cancelled if, for example:
● The counter is reset.
● The threshold is set to a new value.
● The device is re-initialized at the upper and lower endstops.
● Monitoring is deactivated.
With extended diagnostics, the threshold of the message is displayed using columns ① in
addition to the error code ② (Overview of error codes (Page 272)). These columns ① and the
error code ② are shown on the display as follows:
