Device diagnostic messages may appear as a result of the PowerSmart+ Advanced
PQM built-in diagnostic tests performed during a start-up and device operation.
To enter the Device Diagnostics dialog, check the On-line button on the Power
Software toolbar, select Device Control from the Monitor menu, and then click on
the Device Diagnostics tab.
All diagnostic events are recorded to the Event log and can be inspected via Power
Software (see
Viewing the Device Event Log ). The diagnostics status is also recorded to a
non-volatile register, which is not affected by loss of power and may be read and cleared
via communications or via Power Software.
Refer to PowerSmart+ Advanced PQM communication guides for the diagnostic register
address and layout. See
Device Diagnostic Codes in Appendix G for the list of diagnostic
codes and their meanings.
Frequent hardware failures may be the result of excessive electrical noise in the region of
the device. If the meter continuously resets itself, contact your local distributor.
A configuration reset may also be a result of the legal changes in the meter
configuration whenever other configuration data could be affected by the changes.
To clear the device diagnostics status, click on Clear.
