8.3 Malfunction/maintenance

alarm

All status and fault alarms are assigned to a

classified status in the positioner. The default

settings of the status classification are listed

in the code list.

Note: The status classification can be

changed in TROVIS-VIEW and over the

PROFIBUS-PA parameters.

Refer to the Configuration Manual

KH 8384-4 EN on the supplied CD-ROM

(CD 8384-4) for more details.

To provide a better overview, the classified

alarms are summarized in a condensed

state according to the NAMUR Recommen-

dation NE 107. The following status alarms

are available:

4

Maintenance alarm

The positioner cannot perform its control

task due to a functional fault in the de

-

vice or in one of its peripherals or an ini

-

tialization has not yet been successfully

completed.

4

Maintenance required

The positioner still performs its control

task (with restrictions). A maintenance

requirement or above average wear has

been determined. The wear tolerance will

soon be exhausted or is reducing at a

faster rate than expected. Maintenance

is necessary in the medium term.

4

Maintenance demanded

The positioner still performs its control

task (with restrictions). A maintenance

demand or above average wear has

been determined. The wear tolerance will

soon be exhausted or is reducing at a

faster rate than expected. Maintenance

is necessary in the short term.

4

Process-related faults/outside of specifi

-

cations

The positioner is being operated outside

the specified conditions of use.

4

Function check

Test or calibration procedures are being

performed. The positioner is temporarily

unable to perform its control task until

this procedure is completed.

Note: If an event is assigned to the “No

message” status, this event does not have

any effect on the condensed state.

The condensed state appears on the display

with the following icons:

No message –

If the positioner has not been initialized, the

maintenance alarm icon ( ) appears on

the display as the positioner cannot follow

its set point.

If fault alarms exist, the possible source of

error is displayed in Code 49 onwards. In

this case,

Err appears on the display.
