Hi Mike,
Thank you for the suggestions. I performed the shim boards swapping test and
the error followed the board. The red error LED light remained lit on the
same board. Does it confirms that the board is faulty and it has to be replaced?
I also checked the resistances for shim system with a multimeter and the
results are attached. Could you please have a look at them. Coil 13 from shim
system shows a resistance of 6.3 ohms whereas your attached technical document
shows it should be 7.0 ohms. The difference is 0.7 ohms. Do you think this
difference is high enough for coil 13 to go overcurrent or overtemperature
resulting shim current source 13 shutdown. Do you think the board is faulty
or the error is from the shim coil source 13. What is your opinion?
Thank you
Adil Raees
