<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />360kW High Power DC Charger <br />INSTALLATION AND USER’S MANUAL <br />Page 58 of 89 <br />This document is a Property of BTCPower Inc. and shall not be <br />copied, reproduced, or used as the basis for sale or manufacture <br />of apparatus without written permission. 23-Sep-22 Rev D <br />OPERATION <br />ERROR CODE ERROR SOURCE LEVEL DESCRIPTION CONDITION REMOTE ACTIONS FIELD TROUBLESHOOTING STEPS <br />TOWER_INTERMITTENT_SAFETY_ERROR Tower 4 Medium Tower Safety is getting removed <br />which is causing charge session to <br />drop to 0A and stay in that state. <br />Tower safety loss <br />detected during <br />charging session <br />- Review logs for error history <br />- If issue is persistent, contact <br />BTC Power for further <br />assistance <br />- Technician may be <br />dispatched if issue cannot be <br />solved remotely <br />- Check door switches on Tower (3 <br />locations). Check for proper <br />alignment and continuity. (Possible <br />fans causing left door to open, <br />disengaging door switch) <br />- Check safety relay LEDs and <br />ensure all five LEDs are illuminated. <br />You will need to engage front door <br />switch. <br />DISP_ISO_CIRCUIT_FAIL Dispenser 4 Medium Charge session failed due to ISO <br />detect <br />ISO fail detected for <br />greater than 50 ms <br />during charging <br />session <br /> - Check safety loop (MiniPCM to <br />safety relay) <br />- Check cable grounding <br />- Check for any loose wires <br />OFFSET_VOLTAGE_IDLE_ERROR Dispenser 4 Medium Charger detects voltage in idle <br />state <br />Charger detected <br />voltage greater <br />than 10VDC for 2sec <br />before start of <br />isolation test <br />- Check calibration via <br />TeamViewer <br />- Check grounding <br />- Replace MiniPCM <br />TOWER_INITIATED_SHUTDOWN Tower 4 Medium "This error can be generated due to <br />different reasons. E.g. <br />Initiating phase -: <br />1. Power module is not able to turn <br />on and unable give ready status. <br />2. Timeout for vehicle ready signal. <br />Cable Check phase -: <br />1. Cable Check fails because <br />charger is not able to generate <br />requested voltage. <br />2. Cable check fails because <br />charger bleed register is not able to <br />bleed generated voltage <br />3. Timeout for precharge <br />completion. <br />Charging Phase -: <br />1. If vehicle opens contactor and <br />Power module detects it before <br />Dispenser then it initiates shutdown <br />sequence. <br />2. Any fault detected on Power <br />Module which initiates shutdown <br />sequence, i.e., Driver error <br />3. Communication loss detected by <br />power module and initiates <br />shutdown sequence etc." <br />Multiple faults can <br />cause this. If <br />shutdown started <br />from tower and <br />charger will not be <br />able to receive <br />correct fault before <br />shutdown this error <br />will be set. <br />- Review logs for error history <br />- Reattempt charging session <br />- If issue is persistent, contact <br />BTC Power for further <br />assistance <br />- Technician may be <br />dispatched if issue cannot be <br />solved remotely <br />- Check door switches (Tower and <br />Dispenser) <br />- Check fiber transceivers <br />- If no issue is found, re-energize <br />tower and call in for additional help <br /> <br /> <br /> <br />
