Questions and answers
Не работает модуль дисплей
If the display module of a CompAir L07 is not working despite voltage being applied, follow these troubleshooting steps:
1. Check for Internal Drive Errors – If the display is not visible, an internal drive error may be the cause.
2. Replace the Lubrication System – If an internal drive error is confirmed, the entire lubrication system should be replaced.
These steps should help resolve the issue with the display module.
