Alarms
This function checks if a threshold value was exceeded. If so, one of
the LEDs lights up.
To display the thresholds in the spectrum,...
• Press the F key to activate the lower window pane.
• Select the corresponding checkbox in the tree view.
Frequency marker
Frequency markers can be used to more easily identify the character-
istic machine and component frequencies in a spectrum. Frequency
markers are defined for each machine hierarchy level* in the
OMNITREND software and loaded into VIBXPERT with a route /
template.
• Press the F key to activate the lower window pane.
• To display the frequency markers of each single hierarchy level,
press the MENU key and select from the list (see below).
Frequency markers from lower hierarchies are added to higher
hierarchies (meas. loc. -> machine -> machine train).
• Activate the corresponding checkbox in the tree view.
For RPM-dependent frequency markers (e.g. Imbalance -1st har-
monic), the machine RPM must be known - either by manual entry
or by measurement.
