Dear Yaseen, Check the 24v at the X9 connector of the PSU1 board. If this voltage is less you will have display "E". |

Mr.Tambe/Diwa Thanks a lot for your valued suggestions. I was having this problem last night, and when the PMU was displaying E, i checked the voltages on CU2 and T100 card. What i found was this. On CU2, X101-term 13(24Voltsfor binary I/P and O/P)is 21 volts, X103- term 40 (Supply for DTI Board) is 14 volts. On T100 board, There was no voltages at all and the flash led's were not flashing either. I am suppose to get 24 volts on X134- Term 76, X136 term 85. But this was not the case. Theni strip down every thing and checked the cables coming from PSU to IVI board. Basically there are two cables going from PSU to IVI board, they are from X264 and X258. I noticed that in X258 cable one of the pin on the cable connector has turned brown, as if there is sparking. I cleaned it, press it to make it more tight. Put back every thing and started the power. Now the inverter comes on. At this stage i checked the voltage levels on CU2 and T100, All the voltages are same on CU2 and i can see 21Volts on T100 card terminals also and now i can see the LED's on T100 card is flashing also. Now what i worry is, if this is the correct fix, or i might get this problem again. Is the voltage i am getting as 21 volts is good enough or should it be 24 Volts only. If any one has the complete diagram of PSU with all the voltage levels, kindly mail me. We are feeding 24Volts DC from external supply on X9 and it measures 24 Volts. Your help on this will highly be appriciated. My Email id is yaseen3737@yahoo.com regards. Yaseen. |
