Hi,
after receiving the Mutable Instrument Elements Clone, my Rack wont start as the blue lights flash.
I dont really understand why as I should have alot of headroom with my Power Supply..
Does Somebody have an Idea what causes it?
Below you find my Rack and Power Consumption /Supply.
The Model 15 is not connected via the Zeus.
Thanks in advance!
what's it drawing at the -12v rail?
the uzeus states "500ma" at this rail but your post only shows the +12v. My (linited) understanding of electrickery is that both the +&- rails count to your overall power consumption.
personally i would unplug everything and start with yuor elements, then try plugging in each module and powering up one after the other. if it brown outs then it will be power, if the mi elements causes the problem on it's own then it will be a fault with the module perhaps? (or maybe the power supply or ribbon cable).
obligatory safety notice: always disconnect power before swapping modules, check negative orientation of ribbon cables/headers carefully.
do you have a seperate power supply you can test a module on?
Hi, have you removed the jumper from J7 header?
from the uZeus Manual:
Using the –12V Rail:
The –12V rail uses a switching regulator. This switching regulator needs to have
a minimum load of 100mA (out of 500mA) at any given time. The uZEUS has a
factory setting to self consume this current. If your uZEUS is powering more
than four (4) analog modules you can then disable this setting if desired to
make this 100mA available for use by your modules.
While the uZEUS is not powered look for header J7 (located below the blue
resistor) and remove the jumper. Re-insert the jumper such that it comes in
contact with only one pin. Once reinstalled in the system, the uZEUS will
provide the full 500mA of –12V power for your modules.
Hi,
thanks for the advise with the jumper.
I removed it but unfortunatly it still flashes.
With your hint, I could find other threats with simmilar problems.
I even tried to plug in the cables of single modules to doublecheck, if its maybe because of the higher start up power consumption but it still flashes..
Could it be the cable from the wall wart?
It runs13,5V / 1.11A
I have two original tiptop power bricks, each one output 13 V, 3.07 A max. No problem since day one.
the amperage in you case seems low, what power brick are you using? although it's strange if the uZeus rail indicators blinks even with one module plugged in..
Have you tried to remove/swap all the busboards? If it blinks even without busboards connected to the header the uZeus could have an issue. Have you inspected the back of the module? alla caps are in place?
