ERROR CATEGORY Use this function to define whether a process error triggers a notice message or a fault
(8003) message. If you select "FAULT MESSAGES", all outputs respond to an error in accord-
ance with their defined error response patterns.

NOTICE MESSAGES (display only)
FAULT MESSAGES (outputs and display)
!
Press the F key twice to call up the function
ASSIGN PROCESS ERROR (8002).
ACKNOWLEDGE Use this function to define the measuring device's response to fault messages.
FAULTS
(8004) Options:
OFF
The measuring device resumes normal operation when the fault is rectified. The fault
message disappears automatically.

The measuring device resumes normal operation when the fault is rectified. The fault
message has to be acknowledged by pressing the F key on the local display.
Factory setting:
OFF
ALARM DELAY Use this function to specify a time period for suppressing the appearance of fault or notice
(8005) messages .
Depending on the setting and the type of error, this suppression acts on:
• Display
• Relay output
• Current output
• Frequency output
User input:
0...100 s (in steps of one second)
Factory setting:
0 s
"
If this function is activated, error and notice messages are delayed by the time corre-
sponding to the setting before being forwarded to the higher-order controller (process
controller, etc.). It is therefore imperative to check in advance in order to make sure
whether a delay of this nature could affect the safety requirements of the process. If error
and notice messages cannot be suppressed, a value of 0 seconds must be entered here.
