As recent problems after installing protective relay, my team found that as below,
1. LCD Display was dimmed and please find root cause for this issue. Besides, I would like to change LCD which I have already claimed for the new one.
* Coal Mill: IED Serial number 1VHR91091579, LMI Serial number 1YM191327771
* Cooler: IED Serial number 1VHR91091577, LMI Serial number 1YM191268940
2.Sometimes, the protective relay shows "LCD fault" but switch gear is not functioning according to fault command.
Besides, I have already contact ABB service team. However, there is no response form them.
3.If possible, please send the process of setting password in order to use function setting.
