I have a weird situation here, maybe I am missing something easy.
So first, parts being used:
- G.E (Emerson) Rx3i controller
-IC200MDL330L Iso output card 120 vac 16 pt. 0.5 amp
-A.B 800t-qmh2A pushbutton indicator LED light. (universal transformer)
Operation is basically when lift is down and limit is made turn output for light to let operator know lift is down.
we have 4 lifts all on same output card. getting 120 vac out of all 4 outputs. but one indicator light will not light up even with 120vac on the universal transformer. Electricians first started with changing led with no luck. I decided to replace whole assembly beside contact blk. seeing as a did not see that as issue. When part was changed and power back on, light was on like it was suppose to be, Awesome! right lol. Well we came back 5 mins later and it was off again and could not get it to work again. Then decided to change output card, this made no difference. I did switch to analog meter instead of DMM. This happened on a weekend while mill was running and was not like we had changed anything or made a change. Appreciated for any help given!
