Subject: | SGP/EBBR/E26 - Multiplexer 2 Failure From High Temperature |
DataStreams: | sgp30ebbrE26.b1, sgp5ebbrE26.b1, sgp15ebbrE26.b1 |
Description: | Multiplexer 2 is failing during times of control box temperatures above 29 degrees C. The failure begins in the last channel and progresses to lower channels as the temperature increases. It has not yet been determined whether the failure is in the relays or a solid state component of the multiplexer. This condition is probably due to the aging of the device and the millions of cycles that this 10 year old device has made. More failures of this sort may occur in the future. A cure is being sought aside from replacement of the multiplexers to prevent the problem. The indicated measurements need to be inspected to determine which ones are usable. |
