    keyword=R HRS bogie problem

    When I entered the hall, I found the outer bogie motor module 2 tripped on a hardware overspeed condition. I had to cycle power with the safety disconnect switches because the right outer bogie control closet fails to power down when "PSM ENABLE" is turned off (this is the remote reset for the bogie controls.) The cause is probably a bad optocoupler on the brake/interlock control board, I installed a spare board, but the board didn't work properly, so I restored the system as it was when I came in.
