Introduction

NOTE:
An EV card may also contain additional connections for monitoring
magnetic flux and/or shaft voltage and current monitoring.

This manual only contains detailed information on GuardII+ EV monitoring;
for details concerning the GuardII+ Series 4208 Platform, a different
monitoring technology or sensor installations, refer to the Manuals for
those components.

1.2. Features

• Accepts signals from Iris Power LP EVA sensors and/or equivalent third-party
accelerometers

• Simultaneous analysis of up to 32 endwinding vibration axes in any combination of
dual-axis and/or single-axis sensors

• Any pair of axes can be ‘linked’ for combined vector analysis
• Shaft trigger input for synchronizing data collection to trend phase changes

• Analyze measurements and trend at different operating conditions for a more certain
prediction of stator endwinding vibration conditions

• Perform a spot measurement, or automatically acquire and store results for up to 2
years without User intervention

• Triggers that store measurements based on Operating Conditions and specific EV
patterns

• Integrates with the GuardII+ Series 4208 Platform Alert relay contact to alert the User
• Built-in outputs for running measurements to test hardware functionality
