Warnings That Become Faults: WARNING R FAULTWarning R F Display Text DescriptionResolutionFollowing these steps. if fault continues, contact Eaton serviceACF1 CB1 Control Warning Indicates that the PCC (point of commoncoupling) is not responding to command.1. Verify CB1 control-wiring connectionsACF2 Anti-Island Warning Warning asserted when the anti-islandingdetects an island condition.Frequency-based detection: Check for sudden loss of utility1. Clear faults on the HMIACF3 Current Imbalance Any line-to-line current differential exceeding50%.1. Check HMI Monitors, Line currents menu2. Verify reading in Magnum AC breaker3. Check mains AC line wiring4. Check ribbon cable connections.5. Check CT wiring on output bus.CTF9 K8 Control Stack 1 AC contactor (K8) feedback does notmatch commanded1. Check K8 contactor auxiliary feedback wiring2. If first time operating inverter, make sure all factory jumpershave been removed from the contact.3. Check (series-routed) voltages on coil: 208 Vac L-LK8-A1: TB1-15 - K8-A2: TB1-8CTF10 K9 Control Stack 2 AC contactor (K9) feedback does notmatch commanded1. Check K9 contactor auxiliary feedback wiring2. If first time operating inverter, make sure all factory jumpershave been removed from the contact.3. Check (series-routed) voltages on coil: 208 Vac L-LK9-A1: K8-A1 - K9-A2: K8-A2CTF11 K10 Control Stack 3 AC contactor (K10) feedback does notmatch commanded1. Check K10 contactor auxiliary feedback wiring2. If first time operating inverter, make sure all factory jumpershave been removed from the contact.3. Check (series-routed) voltages on coil: 208 Vac L-LK10-A1: K8-A1 - K10-A2: K8-A2CTW14 Pump Control Fault Pump Feedback does not match commanded(evoked after 5 unsuccessful retries)1. Check for control power at the pump: 208 Vac L-L■ F49- TB1-4–TR2-X1 | F50- TB1-11–TR2-X2 | F51- TB1-22–TR2-X3■ 6.25 A Fuses F49 | F50 | F512. Check that AUTO reset has been selected on pumpcontactor K143. Check pump and K14 contactor wiringDCF1 Array Backfeed Detection of current into the array greater than–25 Amps for 10 seconds.1. Check HMI Monitors, Main menu; polarity of “Export Power'”2. Check for damaged modules3. Verify GFDI fuse F3 is intactTable 12.
