Error 79: Fuse 7 Fault

Variable M889

Power is not detected from Fuse 7. This may be caused by a blown fuse. The fuse is used to supply 24V SAFE to the re-referencing and external sensors supply circuit. If this error is present, it suggests that the 24V voltage rail is OK.

What to do now

E‑stop the saw and verify that Fuse 7 (F7) is intact in the right-hand electrical cabinet. If the fuse is blown, replace it with a 1A fuse, otherwise clear the error and resume.

What to do next

If the fuse blows again, contact Vekta Automation for assistance - there may be a short circuit in the system.
