Operating Mode
The ACO-4500 can be operated in one of two modes, selected from within the menu system. The options are either
Auto or Manual control.
• Auto — the ACO-4500 will automatically switch if a fault is detected.
• Manual — the ACO-4500 will switch only when the operator manually selects between Primary and Backup.
Fault Reporting
There is an LCD indication for fault reporting on all channels. If a fault occurs in one of the configured channels on
either the Primary or Backup input, the LCD indicator will illuminate to report the fault. The fault reporting is
persistent, i.e. even if the fault is only an intermittent one, the fault indicator will stay illuminated. If more than one
fault exists, only the “first” one is reported, i.e. counting from the lowest numbered configured channel. As faults
are repaired, the fault indicator displays the next faulty input/channel in the list, etc. Repairing the last fault will
update the LCD display to show that the [last] fault has been fixed - clearing the fault indication will turn the LCD
fault indication off.
