GuardII+ EV Card Operation

4.6.7. High-Tuned Temperature Dependence Trigger

This Trigger detects when there is an indication that a natural frequency is above a
vibrating frequency and resolves down to a specific input. This means that a high-tuned
temperature dependence on input EV1 causes a different Trigger than a high-tuned
temperature dependence 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 High-Tuned Temperature
Dependence Trigger, it will have this icon in EVView.

NOTE:
For a High-Tuned Temperature Dependence Trigger to occur, the load
and temperature Operating Conditions must be available either through a
Remote I/O Unit or directly through Modbus.

4.6.8. Low-Tuned Temperature Dependence Trigger
This Trigger detects when there is an indication that a natural frequency is below a
vibrating frequency and resolves down to a specific input. This means that a low-tuned
temperature dependence on input EV1 causes a different Trigger than a low -tuned
temperature dependence 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 Low-Tuned Temperature
Dependence Trigger, it will have this icon in EVView.

NOTE:
For a Low-Tuned Temperature Dependence Trigger to occur, the load and
temperature Operating Conditions must be available either through a
Remote I/O Unit or directly through Modbus.

4.6.9. Resonance Trigger

This Trigger compares measurement data across multiple measurements to detect a
change in vibration that is indicative of resonance and resolves down to a specific input. This
means that resonance on input EV1 causes a different Trigger than resonance 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.
