Hi guys,
I'm hoping someone can help out. I have 2 x powered Zeus and 2 x passive connected up via one power plug as per instructions. (e.g. Powered 1 sends to powered 2 and passive 1. Powered 2 sends to passive 2.
Ive just filled up 168hp which as taken me to need to use the 2nd powered/passive boards for any new modules.)
I just noticed however that the +12V led I not lighing on both of these - the other 3 are blue. From memory in the past they have all lit up. I did plug a new module into one of them (correctly oriented- but then noticed this issue and took it out - it didn't change back. I have since tested the module on my other boards and it works fine.
I have rechecked all the connections any thoughts? |

| I have one bus board that came from AH with the -12v light not lighting up (its a powered board) but it appears to be at least mostly functional as the passive board chained off of it is getting -12v... It might be just a dead LED, but I'll have to do some further testing as I'm getting a bit of weird behaviour with a couple of modules... Maybe something in my zeus system is in fact faulty... Or maybe I just have a kinda shitty connection somewhere. |

I too have a dead blue led on one of my Tiptop Passive boards...but cannot detect any faults in the power system. Emailing Tiptop was helpful and reassuring but distilled down to "dead led, you should be fine." I've had no problems. _________________ http://soundcloud.com/starkaudio |

Did TipTop get a run of bad LEDs or is there another issue?
I am watching in earnest as I am planning an expansion to a new case and had decided to go with the Zeus + Cincon system for power. I am a couple months out at least so perhaps it is best to wait and see. |

Did you mesure the voltage on the +12v rail? |

I have a blue led on my uZeus that's on sometimes, and off sometimes. Measured, and the power on the flying busboard doesn't change, everything works as it should, just the led that's acting up. Looks a bit as if TipTop has gotten a batch of bad leds... _________________ bandcamp

I just got a uzeus in that when I plugged a bunch of modules up the -12 led dims to almost off, thought I had an Asys 110 in backwards so freaked and turned it around without thinking it through and THEN blew it up, grrr.

There was an issue on the initial run which Gur corrected where the negative rail was going down on some boards. If gur said there's a dead led on a newer run then no big whoop, but if you're using like all makenoise + only modules or something on said board the - rail problem wouldn't be apparent. You might check that negative rail out just for grins if it's an older board. _________________ Soundcloud | Twitter | epicurean.com |

Nice!
The Zeus boards are designed for switching power supply input, and according to the manual on TipTop's site are designed for input switching power supplies in the range of 9VDC to 18VDC. From the linked thread it appears that the supply you are using has an output of 25.6V, so I would be a little worried about over driving the Zeus boards, unless you have input from the company that it is safe to do that.
I don't know much about LED driver circuits, but I work in an industrial display and graphics research lab on displays and lighting, including solid state (pretty much all optics for me) and with other EE's who design LED drivers and an ME who specializes in thermal engineering for sold-state lighting devices. I know that LEDs might require proper driving circuitry to function optimally and with long life. Thermal management is also a big issue at the die and package level, but to the integrator proper heat sinking and/or active cooling is more an issue for higher power LED packages and not "jelly bean" style LEDs. This is a long way of saying that it might not just be the LEDs themselves that are having the unusual behavior, but the driver circuit or a combo of the LED-driver circuit. Also depending on the type of LED, thermal management can be an issue but probably not in this case. Sorry if this is stating the obvious. |

About the high voltage (25.6v), I think itīs a regulator problem.
I am thinking about to change the flickering led to see what happens...
In my board it`s the +12v led, if itīs the same for everyone it might not be a bad batch of leds...  |

LEDs on power bus boards don't have a driver circuit. They are just connected through a resistor to the power supply rail. So bad LED, bad resistor, or bad soldering are the only possible problems with them. And these won't have thermal issues like LEDs used in lighting situations. Those have to dissipate tens or hundreds of watts, while these dissipate a few thousandths of a watt. _________________ Dave Jones Design | http://www.jonesvideo.com |

hummmmmmmmmm, Could this be the R1 resistor on the Zeus passive?
I donīt have much knowledge about electronics, so, how can I mesure these resistors with a multimeter?

Ok, R1 and R2 both are 4.7K ohms giving 4.68 at the multimeter and R3 2.2K ohms giving 2.17.
Now after this test I donīt think it is a resistor problem. |

| You can also try this test to see if the LED is okay. Get a 9v battery and with wires connected to the battery tap into the Ground and + voltage you want to test. For example ground and +12v on the pins. Of course don't have any modules or anything else connected to the passive strip board you are testing. The light should light up a little bit even with 9v and 4k7 resistor. At least you will know if it is the passive that is the problem or your power supply. |
