Troubleshooting

7. Troubleshooting

The GuardII+ does not typically require any special maintenance. If the monitor does not
operate as expected, there is some basic troubleshooting that can be performed before
contacting Iris Power LP Technical Support.

WARNING:
All troubleshooting activities need to be performed by qualified personnel.

NOTE:
While troubleshooting, connections may need to be temporarily changed.
Once troubleshooting is finished, make sure that the original connections
are restored.

The GuardII+ indicators provide some status information. This section describes the use
of the indicators during troubleshooting; for full functional descriptions of all indicators, refer to
the GuardII+ Series 4208 Platform User Manual. Additional diagnostic information will be
available through IAM.
The troubleshooting procedures described here are for a check of all PD card functions.
Sometimes it may be obvious that a particular problem does not exist; if the monitor is not
producing a synchronization error, then there isn’t a problem with the ac synchronization; so,
there is no benefit to checking it. In these cases, a complete check may not be necessary;
just go to the relevant section.
Contact information for Iris Power LP Technical Support is listed in Section 7.4. If repairs
are required, Iris Power LP Technical Support will issue a Return Material Authorization (RMA)
with instructions to return the product. If the monitor is out of warranty, a repair evaluation fee
applies. The warranty details are given in the Selling Policy of Iris Power LP.

NOTE:
This manual contains troubleshooting information specific to the PD
system:
• For details on troubleshooting generic GuardII+ functions, refer to
the appropriate technology User Manual.

• For details on troubleshooting a different monitoring technology,
refer to the User Manual for that technology.
