11.3.2 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 Message due to

OFF Advanced diagnostics not activated

On 1 Fault message output for threshold 3 fault messages (one-stage)

On 2 Fault message output for threshold 3 fault messages and alarm output 2 for threshold 2

fault messages (two-stage)

On 3 Fault message output for threshold 3 fault messages and alarm output 2 for threshold 2

fault messages and alarm output 1 for threshold 1 fault messages (three-stage)

Possible settings of the "XDIAG" parameter

when

Possible causes

1 No Remaining control

deviation

Always active ... the control deviation

disappears again.

Compressed air failure,

actuator fault, valve fault (e.g.

blockade).

2 No Device not in the

automatic mode

**. FCT

nA or = nAB

... the device is switched to

the automatic mode.

The device has been

configured or is in the manual

mode

3 No Binary input BE1

or BE2 active

**. FCT

nAB and binary

function BIN1 or

BIN2 on "On"

... the binary input is no

longer active.

The contact connected to the

binary input was active (e.g.

packing gland monitoring,

overpressure, temperature

switch).

4 Yes The limit of stroke

number exceeded

L. STRK≠OFF ... the stroke counter is reset

or the thresholds are

increased

The total path covered by the

actuator exceeds one of the

set thresholds.

5 Yes Limit of changes of

direction exceeded

O. DCHG≠OFF ... the counter for changes of

direction is reset or the

thresholds are increased.

The number of changes of

direction exceeds one of the

set thresholds.

6 Yes Limit of the lower

hard end stop

exceeded

F. ZERO≠OFF

**.YCLS = do or up

... the deviation of the end

stop disappears or the device

is re-initialized.

Wear and tear of the valve

seat, deposits or foreign

bodies in the valve seat,

mechanical misalignment,

friction clutch moved.
