Hello,
I have a OSA-5585 cesium PRS and it is not working.
On the local manager i have a cesium module alarm. I opened it and found
out
that the high power module that drives the cesium oven is not working
because
it doesn't receive the correct voltages. Instead of 10 and 24 volts it
only
gets 8 and 13 volts. So i pulled out the power board and found out all the
capacitors were bulged. I replaced all of them with the corresponding
values
and now i have 0 volts on its output and some smoke coming from a diode on
the
board.
Does anyone have some schematics for this unit, or could at least help me
with
the connectors on the power board? I found the output connectors that
should
deliver the 10 and 24 volts but i don't know what the inputs are. If i can
find
out what the inputs are then i could debug the board easier.
Please excuse my writing, english is not my native language.
