Dear All,

          This is my first message in this forum, and I'm in need of some help from experts on this matter. For a marine vessel, Auxiliary Boiler Fans are equipped with ACS 880 Drives (2 drives, 1 for each fan). Just 2 days ago, suddenly both VFDs started to show the attached screen, and pressing the Start/Stop or Loc/Rem buttons does not have any effect; nothing changes on the screen. I would appreciate any suggestions and recommendations from experts. The controller is connected via LAN cable to the drive, for your information.
