Jumper Description
1 If the magnetron failure detection is being used:
The jumper should be positioned between the enable pin and centre pin.
If not then the jumper should be positioned between override pin and
centre pin.
Please note that if the magnetron failure detection is not being used then
fibre optic cables and diode board 11M0363 are not required. This is
clearly indicated on the PCB itself.

APPENDIX 6
: Logic Board & Magnetron Failure Detect
11M0416 KFC optic Logic PCB with Magnetron Failure Detect
in the event of failure the system will automatically compensate and double the remaining cook
times thus ensuring that the program achieves its target temperature in the food product. At the
end of the cooking cycle the system will display either “E4” = left hand magnetron failure or
“E5”= right hand Magnetron failure. In the event that both Magnetrons fail the system will report
an “EA” error. Once a failure is detected, It takes 4 seconds before the control circuit reacts thus
preventing false triggering
