View Full Version : tracer summit phase loss question
04-21-2008, 09:52 AM
I'm a new poster but long time surfer of your site.... I have tracer summit as a building automation software for my church. About 2 weeks ago we lost power from the electric company and the generators started up and we ran on emergency power for a little over a hour.. ever since we have had a phase loss alarm and it puts all our ahu's and rtu's in priority shutdown. The problem is I checked all phases coming into the building and all is well. Is there any way to reset this alarm and get it back to normal?

You're going to need to figure out how the alarm is being generated. Is there a phase moniter connected to an input of some input/outcard or controller? Is there a software binary input in summit that is still alarmed? You will need to dig some.

there is a phase loss monitor on our main incoming power supply and it is showing all is normal.... as for the binary input on tracer Ill check on that... thanks for your intrest I really am thankful

if you are just interested on resetting the alarm and getting the "alarm" back to normal, it could be as simple as going into "Alarm and Event Log" tab in summit and try to acknowledge the alarm... basically telling the BCU that the alarm source has been fixed.
Also, mallron is right. there must be a software binary input in summit and referenced to an actual binary input of a board (e.g. mp580/581), check that as well.
to perform Priority Shutdown, there must be a CPL running on the background to command those units or manually overriding each UCM at a higher priority level...
just my 2cents :rolleyes:
