i've been helping a guy t/s an interm prob w/ a mont/kone miprom controller car will stop in the up dir. w/ a reset/brownout fault on the pwr supply board temp trapping people. the unreg pwr supply read 24 vdc w/ no ripple but the reg pwr supply would get back to the rack at 21 vdc. w/ no drop off while car was running up and down the h/w. had him swap out the pwr supply bd the 21vdc bumped up to 24 vdc and everything looked good. but after a few runs car had same prob. so we adj the pot on bd to 25 vdc but interm would trip off. next watched bldg pwr controller calls for 208 + - 10vac phase to phase read 218 vac & 126 vac to ground all w/ in tolerance but on 1 occ. caught the voltage at 202 vac not good. had their elec. come out he said everything checked good even w/ bldg fully loaded. so now we got the car down while the pwr company monitors the bldg pwr poss. xfmr going bad. now heres my ? is there a way to disable the brown out/reset feature on this bd. i think it clamps through a chip set not sure though any help would be great. thanks.
