Check grid frequency and quality. PLL was unable to identify valid grid frequency and phase AC line PLL successfully locks GFCI cannot function without locked PLL, Wall Connector will not operate Wall connector input terminal temperature sensor shorted, open, or too cold info from manualCC_A026 Input terminal temperature sensor measured as open or short circuit Wall connector input terminal temperature reading passes rationality check Vehicle side protective earth is disconnected from wall connector info from manualCC_A002 Vehicle side protective earth is disconnected or high impedance Vehicle side protective earth is connected Wall connector will not allow charging until vehicle side protective earth is connected More than three units configured as slaves were detected on the sharing network info from manualCC_A023 More than three units are configured as slaves in the sharing network Three or fewer slave units are detected on the sharing network info from manualCC_A028 Wall connector current limit selection dial is set to an invalid position Rotary dial changed to valid setting and unit is power cycled Microcontroller supply rail is incorrect info from manualCC_A020 Microcontroller supply voltage is outside of valid range Microcontroller supply voltage enters valid range Wall Connector WiFi module hasn't checked in with the real-time processor WiFi module has failed to check in due to a long running process, update, or software bug WiFi module checks in with the real-time processor Charging will continue normally, but connectivity and billing may be delayed or unavailable Wall connector charge handle temperature sensor shorted, open, or too cold info from manualCC_A027 Charge handle temperature sensor measured as open or short circuit Wall connector charge handle temperature reading passes rationality check AC RMS input voltage is too low info from manualCC_A008 AC RMS input voltage fell below 160 V RMS for more than 2 seconds AC RMS input voltage rises above 170 V RMS for more than 2 seconds Wall connector will not allow charging while the input voltage is too low Ground fault detection circuit self test failed info from manualCC_A004 Ground fault detection circuit self test passed after being re-run. Test re-runs after 15 minutes (non-EU), cable cycle, or reset button. Wall connector will not allow charging until the ground fault circuit self test passes info from manualCC_A029 Pilot level transitions to invalid voltage level Wall connector will not operate while pilot level is invalid Wall connector PCBA temperature sensor shorted, open, or too cold info from manualCC_A025 PCBA temperature sensor measured as open or short circuit Wall connector PCBA temperature reading passes rationality check info from manualCC_A015 Neutral conductor is grounded on vehicle side info from manualCC_A005 Neutral conductor conductor impedance to ground on vehicle side is less than 2 Ohms with contactors open Neutral conductor impedance to ground on vehicle is greater than 2 Ohms with contactors open Wall connector will not allow charging if there is a short between neutral and protective earth when a vehicle is connected before closing contactors Wall connector proximity line disconnected or vehicle is not providing proximity voltage info from manualCC_A019 Proximity line in charge cable has no voltage present but a vehicle is connected Proximity line in charge cable rises to a valid voltage level Wall connector will not allow charging while the proximity line is broken because it cannot determine if the cable is latched Wall connector charge handle is too hot Wall Connector handle temperature exceeds 65C Wall connector handle temperature falls below 60C Ground fault current exceeded threshold info from manualCC_A003 Ground fault current has been corrected and the test re-run. Test re-runs after 15 minutes (non-EU), cable cycle, or reset button. Wall connector will not allow charging until ground fault current path is corrected and the test re-run. info from manualCC_A018 Master and slave units in sharing network have different nameplate current ratings info from manualCC_A030 Wall connector nameplate current rating differs from other wall connector in sharing network Wall connector no longer detects units with different nameplate current rating in the sharing network and the unit is power cycled Wall connector protective earth is disconnected or grounding scheme DIP switch set incorrectly info from manualCC_A001 Wall connector AC input side ground impedance is above threshold Wall connector AC input side ground impedance has fallen below threshold for adequate time Wall connector will not allow charging until the protective earth connection is corrected Output voltage, current, and energy monitoring failure Metering hardware fails to initialize Metering hardware initializes successfully Wall Connector cannot detect welds, over-current, or meter energy. Wall Connector will not operate.
