    After replaced the power supply board in the morning, the right Q1 field was not recovered to the value (0.01414) before 06:30 July 10, 2010. The filed value was about 0.01402. When it tripped at 14:18, it was set to 0.01398 until we recognized the difference. Then we set it back to 0.01413 at 14:30. Runs between 2010 and 2020 may be affected by this issue.
