After the NE80 is upgraded, the power monitor board (generally 24 slots) cannot be registered or is displayed as Abnormal after it is registered.
When the power monitor board cannot be registered, the "run" indicator on the board flashes rapidly in green. When the monitor board is displayed as Abnormal after it is registered, the alarm of the board flashes in red and the alarm of the MPU also flashes. In addition, the buzzer gives the sound alarm.
Try plugging in and pulling out the board repeatedly. After that, if the board is displayed as Abnormal after it is registered, replace the board. If the board cannot be registered, check the DIP, which is in the alarm panel of the monitor board. The normal case is that the DIP switches of No. 2, 3, 5, 6, 7, and 8 are in the On state and others in the Off state.
