Use this function to specify a time period for suppressing the appearance of fault or
notice messages.
Depending on the setting and the type of error, this suppression acts on:
• Display
• Relay output
• Current output
• Frequency output
User input

"
Caution!
If this function is activated, error and notice messages are delayed by the time
corresponding 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.
