    11.2 AUTO OPERATION RUNNING 11.2.1 ILLUSTRATION Press manual/auto transfer key , and auto status indicator is illuminated; Controller is in auto status. In auto mode, controller will transfer switch based on the status of A power and B power, transfer priority and auto trans./restore status to ensure supply for load.

  • Page 20: Auto Trans. None Restore (Active For Mutual Backup)

    11.2.3 AUTO TRANS. NONE RESTORE (ACTIVE FOR MUTUAL BACKUP) When the “Auto Trans None-Restore” function is set, and “Mutual Backup” is active, A power acts as the master source. If A power is normal, it closes the A power switch, supplying the load. If A power becomes abnormal while B power remains normal, the controller opens the A power switch and closes the B power switch, transferring the load to B power.

  • Page 21: Auto Trans. None Restore (In Active For Mutual Backup)

    11.2.4 AUTO TRANS. NONE RESTORE (IN ACTIVE FOR MUTUAL BACKUP) When Auto Trans. None-restore and Mutual Backup is inactive, A power is master. If A power is normal, it closes. When A power is abnormal and B power is normal, A power opens and B power closes. If A power recovers to normal, the switch remains at B power close status.
