XDIAG parameter

You can use the advance diagnostics parameters to display fault messages in one, two or
three stages. In addition to the fault message output, alarm outputs 1 and 2 are then used.
For this purpose, set the "XDIAG" parameter as described in the following table:
Settings of XDIAG
OFF
On 1
On 2
On 3

Meaning of error codes

10.3.4.1

1 Remaining control deviation

The deviation between the setpoint and the actual value is continuously monitored in
"Automatic" mode. The fault message for a remaining control deviation is activated
depending on the setting of the application parameters " TIM" - monitoring time for setting
the fault messages - and " LIM" - response threshold for the fault message. The fault
message is cancelled as soon as the control deviation drops below the response threshold.
This monitoring function is always active.
10.3.4.2

2 Device not in "Automatic" mode

When the device is not in automatic mode, an error message is generated if the ' FCT'
parameter (function of fault message output) is set correctly. A warning is then sent to the
control system if the device was switched to manual or configuration mode on-site.
10.3.4.3

3 Binary input BIN1 or BIN2 active

If the binary input is activated, an error message is generated when the " FCT" parameter
(function of fault message output) and the "BIN1" parameter (function of binary input 1) are
set correctly. For example, it can be a switch to monitor the packing glands, a temperature
switch or a limit switch (e.g. for pressure).
Binary input 2 (in the optional alarm module) can be configured in a similar manner.
