ALARM DELAY Description
Use this function to enter a time span for which the criteria for an error always have to be
satisfied before a fault or notice message is generated. Depending on the setting and the
type of error, this suppression acts on the display, the current output and the frequency
output.
!
Note!
If this function is used, fault and notice messages are delayed by the time corresponding
to the setting before being forwarded to the higher-level controller (PCS, etc.). Therefore,
check in advance whether a delay of this nature could affect the safety requirements of
the process. If fault and notice messages may not be suppressed, a value of 0 seconds
must be entered here.
