I'm currently working for a hire company as a maintenance tech, and have a betapack 1 which is having a few problems.
I'm gussing the cause was probably a power surge as the transformer and voltage regulator where both blown, as far as i know the last time this was use it was hooked up to a generator..
after repairing these two problems the unit turns on (Power light goes on and 23v comes out the transformer),
the problem now is that it doesn't turn the lights on, i checked a the triac cards and they all preform fine when i wire them into the test bed. two of them did have blown opto-iso's though.
after hooking an oscillisope up to the outputs of the main board no matter what level i set it too dimm it was just a +/-15V noisy sine wave at 50hz (mains in my area), on all channels.
does anyone have a cuircuit diagram of the main board which could be sent to me? or else does anyone know which component is blown up? as far as i can tell the rectifier after the transformer works. but with out a circuit diagram i can't be sure.
as far as i know the last time this was use it was hooked up to a generator.
chears,
Duncan
