Error 76: Fuse 4 Fault

Variable M886

Power is not detected from Fuse 4. This may be caused by a blown fuse or a problem with the 24V DC power supply. The fuse is used to supply 24V DC to the miscellaneous circuit supply.

What to do now

E‑stop the saw and verify that Fuse 4 (F4) 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

  1. If the fuse blows again, contact Vekta Automation for assistance - there may be a short circuit in the system.
  2. Verify that the 24V DC power supply is operating correctly.
