Warnings That Cannot Become Faults: FAULT R Fault R ∞ Display Text DescriptionResolutionFollowing these steps. if fault continues, contact Eaton serviceCL1 SCADA Comms Control (SCADA) Communication FaultIndicates loss of connection between theSCADA system and the COMMC board.1. Check HMI System Diagnostics menu for indicator2. Verify SCADA system is plugged into Ethernet switch3. Verify SCADA network settings4. Ensure that SCADA system is writing to communicationheartbeat set-point.CL2 Internal Comms Loss of CAN communication was detectedbetween COMMC board and main controlboard (PIB).1. Check COMMC and PIB cabling and terminations.2. Reset (cycle) power to the COMMC and PIBCL3 Remote IO Comms Comm loss for any of the remote IO boards 1. Check cabling and termination2. Reset power to boardsCL4 I/O PLC Comms Comm loss with optional custom IO PLC 1. Check Ethernet cable connection2. Validate that PLC IP address matches d.351 configurationCL5 Remote IO HW One or more Remote I/O boards is notconnected to the PIB1. Check wiring to PIB, connector J152. Observe which LED on the PIB board is illuminatedD30~D32 correspond to CAN1~CAN3D34~D36 correspond to CAN4~CAN6DCF0 Array Low Low irradiance detection.This is detected when DC Power is less than7.5 kW or DC Voltage is under minimum PV Vdcfor >10 msec.Normal Operation (No Action Required)■ Evening transition from power-export to sleep states due towaning irradiance■ Common in early morning when low irradiance can’t supportpower-exportAbnormal Operation (typically when solar irradiance > 200 W/m 2)■ Verify solar array modules for damage and source and outputckts wiring defects■ Verify inverter re-combiner, input OCPDs and bus-barconnectionsXW1–XW8 User-Defined User defined Warnings as part of theMulti-Function IO Feature set.Examples: Typical to the medium-voltagetransformer;1. Liquid Level Alarm; Activates low levelalarm circuit.2. Liquid Temperature Alarm 1.Low set-point3. Liquid Temperature Alarm 2.High set-point4. Pressure Switch Alarm; Activates at+6.0 PSIG falling5. Vacuum Switch Alarm; Activates at–2.5 PSIG fallingConsult Eaton prior to Inverter order/factory build1. See equipment delivery documents
