S611 Fault Codes
Code Fault Condition Solution
3 Watchdog • Firmware fault —
5 Internal Memory • Internal FRam memory error • Component failure on printed circuit board
• Contact EatonCare for service
6 User Interface Communications
Failure
• Communications to UI have been
interrupted
• Possible hardware failure
• Firmware is not communicating internally
• Cycle 120 Vac control voltage power to attempt to
clear problem
Note:
The User Interface module is not required (default) for operation of the S611 after the parameters have been set. The S611 may be configured to fault if
the User Interface module is removed by enabling the User Interface Comm Loss Fault parameter setting in the Advanced Config. menu. To reinstall a UI
that has been removed, remove 120 Vac control power, reinstall the UI, then restore 120 Vac control power.
7 Internal Program Memory • Corrupted firmware or memory
• Flash CRC
• Cycle 120 Vac control power to the S611
• Contact EatonCare for service
Note:
Internal memory issues may be either a hardware or firmware failure. In the event of a firmware problem, cycling 120 Vac control power may restore
proper operation to the S611. If cycling power does not correct the fault condition, contact EatonCare for service.
8 Voltage Zero Cross Lost • Mains voltage lost
• Phase L1 or L3 lost
• Load disconnected
• Restore mains or lost phases
• Verify that the load is connected and any disconnect
devices are properly engaged
• Contact EatonCare for service
Note:
The SCRs are unable to fire if there is no source voltage and/or load on the unit. Verify that all mains control devices are properly connected and powered
prior to initiating a START command.
9 Communications Loss Port A • Communications to a remote network
controller was lost during run cycle
• Device disconnected
• Connection lost
• Reattach network controller, verify that the unit is
recognized by the system controller
Note:
This fault corresponds only to network communications. It does not relate to internal communications among components on the printed circuit board
(PCB).
10 Communications Loss Port B • Communications to a remote network
controller was lost during run cycle
• Device disconnected
• Connection lost
• Reattach network controller, verify that the unit is
recognized by the system controller
• Comms Port B adapter module failed or disconnected
Note:
This fault corresponds only to network communications. It does not relate to internal communications among components on the printed circuit board
(PCB).
