guedesluz Posted June 16, 2014 Posted June 16, 2014 Hey Guys... I think I faced some short circuit or overload problem with my PLM and ISY.... Today I noticed that my ISY isn't working and doesn't appearing on the network. The lights on the network connector were all off. I look at the PLM and noticed that it was off too... Then I decided to open the PLM when I faced this situation (picture attached). I think that something overcharged my home electrical system and PLM suffered the consequences... Unfortunatelly I think that ISY was gone too because it is not communicating with my router anymore... My doubt is, considering that PLM is directly connected to electrical line, shouldn't it have some protection like a fuse or something? Considering that it doens't has, shouldn't ISY have something too? What could I've done to prevent that??
Brian H Posted June 16, 2014 Posted June 16, 2014 It does look like your home took a large power surge. There is a MOV on the top of the board that should absorb some surges. You may also find a blown MOV on the top of the PCB. D4 and maybe others also look blown The possible burn mark near pin 2 of the the LNK354GN {Switching regulator IC] would also indicate a fairly large surge. The secondary of the switching power supply in the PLM is isolated from the AC Line powered side. I doubt the surge got into your ISY controller. From the PLM. Though anything is possible. Is the Blue power LED on your ISY Controller On? It is possible the surge also got the external power supply used to power your ISY controller. Not communicating with your network could indicate your router also took a hit. If there is no PLM connected. The ISY Controller maybe in the Safe Mode and I don't know if that disables network communications. I have seen a few users here. That say a whole house surge suppressor has helped them in protecting their installation.
guedesluz Posted June 16, 2014 Author Posted June 16, 2014 Yes that was a ruge power surge and I have a suspicion... Last week, my dad was trying to fix a luminaire (IN THE MIDDLE OF BRAZIL GAME ) and suddenly the 3 phased switch was down. I saw that he was fixing a screw that made a short circuit between two phases. Didn't remember any other event... Just yesterday I realized that the ISY was gone... The PLM is gone for sure. I don't think I have a way to save it. Should I try to sent it to SmartHome for some maintenance? About the ISY, it seems everything fine. It turns on, the powersupply is ok, all the leds are on and I can reset it. I opened it and don't see any signal of damage on the board. My doubt is that, when I conect the ethernet cable, nothing happens and the connector leds didn't turn on... sad...
Brian H Posted June 16, 2014 Posted June 16, 2014 What LEDs are On when you power up the ISY Controller? With no PLM the Blue Rx LED maybe ON. With no Network connection. The Blue Memory and Red error LEDs should be flashing. I would try the ISY controller on a different Router or port on the router. To see if your router also took a hit. You can't log into the ISY controller at all?
guedesluz Posted June 16, 2014 Author Posted June 16, 2014 Can't remember exactly now, but as I remember I got all lights on and the blue memory and error blinking. I tried ISY on a different router port and got nothing. What is intriguing me is that even the ethernet connector lights are on when the cable is plugged... shouldn't?
Techman Posted June 16, 2014 Posted June 16, 2014 guedesluz, Here's the trouble shooting info for the ISY994. Hope this helps
Brian H Posted June 16, 2014 Posted June 16, 2014 Memory and Error flashing is a network connection issue. As pointed out in the chart supplied above. Have you verified that the router is working with other devices? I would think the Green LEDs on the network jack would be on if there was a valid network connection. Maybe UDI will have some further tests you can do to verify the ISY controllers condition.
guedesluz Posted June 17, 2014 Author Posted June 17, 2014 I won't have time today but gonna do some tests tomorow... I tried different ports and nothing happened... Afraid...
Brian H Posted June 17, 2014 Posted June 17, 2014 OK. Will be waiting when you have any more results.
guedesluz Posted June 19, 2014 Author Posted June 19, 2014 I tried it on again. Changed cable, reset ISY, changed router port... I even took out my PC from the router and put the ISY in its port, all with the same error... RX on steady, problem with the PLM. Ok I understand that because my PLM is gone. Memory and Error blinking... sad..
Michel Kohanim Posted June 20, 2014 Posted June 20, 2014 Hi guedesluz, If memory are error are blinking, it's network related. With kind regards, Michel
Brian H Posted June 20, 2014 Posted June 20, 2014 If the ISY controller is still blinking the Error and Memory LED. Using the router port the computer functions correctly with. The ISY controller may have taken a hit in the network interface area. I would not think that was a common thing to happen but in my years of electronic testing. I have seen things that in theory should not have happened. That is a big flash mark in the photo. Do you have any idea how high the voltage was?
guedesluz Posted June 20, 2014 Author Posted June 20, 2014 Michel... I know that is network related but I'm hardly declined to find out that there's a hardware problem on Isy now. I tested it with different ethernet cables on two different routers that are working ok and got the same errors.... I don't know how big was the voltage but it was a short circuit between 2 phases. A present from my dad changing a luminaire.. What should I do with this ISY know? Can I send it to Universal Devices back to see if there's a way to fix it?
Michel Kohanim Posted June 20, 2014 Posted June 20, 2014 Hi guedesluz, I am so very sorry to hear. Yes, please send your original invoice and subject: RMA Request, to sales@universal-devices.com and point to this thread. With kind regards, Michel
guedesluz Posted June 21, 2014 Author Posted June 21, 2014 Michel I'm gonna see if I still have the original invoice, really don't know. Could this be a problem? I don't know if this could realy be considered as a RMA as long as it was apparently caused by my dad... I live in Brazil but I have a partner that lives in Chicago and he is comming to Brazil in november to visit the family. I'll send the ISY with him so he can send it to you ok?
Michel Kohanim Posted June 22, 2014 Posted June 22, 2014 Hello guedesluz, That should be OK. With kind regards, Michel
guedesluz Posted July 26, 2014 Author Posted July 26, 2014 Hey Michel, the ISY and PLM that I told are with my partner at Chicago together with original invoice from SmartHome. Can you confirm me adress and responsible that I should send them?
Michel Kohanim Posted July 27, 2014 Posted July 27, 2014 Hi guedesluz, Please send your request to sales@universal-devices.com ... it shouldn't be a problem. With kind regards, Michel
