GuardII+ EV Card Operation

When a Level-Based Trigger occurs, multiple measurements are saved:

• Summary data from the 4 measurements before the measurement that caused the
Trigger.

• Summary and raw data is saved from the measurement that caused the Trigger.
• Summary data is saved from the 3 measurements after the measurement that caused
the Trigger.

Figure 4-3 Level-Based EV Trigger Archiving

When a Level-Based Trigger is saved, it will have one of the following icons in EVView:
This icon is used when a measurement saved due to a Moderate Level
Trigger.
This icon is used when a measurement saved due to a High Level Trigger.

This icon is used when a measurement saved due to a Very High Level
Trigger.

4.6.6. Stator Current Correlation Trigger
This Trigger uses the stator current to detect when a correlation with vibration levels is
present and resolves down to a specific input. This means that a stator current correlation on
input EV1 causes a different Trigger than a stator current correlation on input EV12; each
input has its own Triggers.
The Trigger interval for this Trigger is 30 days; additionally, the result must be confirmed
over multiple measurement cycles before the Trigger occurs.

When a measurement is saved in due to a Stator Current Correlation Trigger,
it will have this icon in EVView.

NOTE:
For a Stator Current Correlation Trigger to occur, the load, temperature
and stator current Operating Conditions must be available either through

a Remote I/O Unit or directly through Modbus.
