Anyway to tell mains power was lost

[marcuslee]

Hi All,

Anyone know if there's a way to tell when the IPD(s) have lost their mains power?

Also when say the QLD's loose their mains input (they have blinking LEDs physically speaking on them, so I'm wondering if there's a way to view a log via Cortex)?


Also generally speaking, am I correct in saying Tools > Logging... is literally logging everything going on, and therefore the answers to both the above may lie in there (but it might even need some fairly in depth expertise to start pulling apart the logged packets with NodeID's and specific decimal codes which are sent on the network)?


Also does Cortex use WinXP, Event Viewer, Application Logging at all? I'm also trying to figure out if WinXP might have some way to see when the PC had to fall to backup battery...

QLDs and SLDs monitor the mains power and when this is lost they generate a 'module function error' report. If your logging settings include Auto logging on failure to file (which is default) then the errors and surrounding data will be captured. You should NOT set the 'To file always' option except for special fault finding sessions since this will otherwise cause continuous logging and hard disk filling up.

In the case of an SLD the error could be caused by a blown light bulb since the SLD is an inline device. However a QLD is not affected by bulb condition.

Conversely when mains is restored you get another such 'error' report. In each case Cortex does however interpret into words such as mains lost or bulb failure or mains resumption and this goes into the log file too.

There are connections for both types of events in the parent object connections list so that for example you can trigger events, send messages or whatever based on mains loss/resumption.

Forgot to mention of course that the IPD also monitors its power source and can generate event triggers upon power loss and indeed this information is one of the alerts utilised by default in Cortex Alarm Pro's envirionmental monitoring alarm. Since there is typically some inherent capacity in the power source the signal from the IPD is less likely to be triggered by short power glitches.

Thanks Karam - I did find it inside the log. For anyone following this thread:
"20:46:58 Module Function Error, g-qld001-2, Node=1054
20:46:58 Last Tx Packet:
20:46:58 Last Tx Address: 103C
20:46:58 g-qld001-2 Mains failure

Also thanks for the pointer towards the connections.

Cheers,
