7 Commissioning 7.1 Status indicators 7.1.1 Battery pack O FF O N CONN ECTIO N KIT There are four LED indicators on the front of the battery packs to show its operating status. ON: This indicator stays on while the battery pack is supplied with power for operation. Charging: This stays on while the battery pack is charging. Discharging: This stays on while the battery pack is discharging. Warning: This comes on when the battery pack is in a warning state. See Troubleshooting on page 45.
Commissioning 7.1.2 RESU Plus There are four LED indicators on the front of the RESU Plus to show its operating status. ON: This indicator stays on while the battery pack is supplied with power for operation. Pack 1: This stays on while the first battery pack is online with the RESU Plus. Pack 2: This stays on while the second battery pack is online with the RESU Plus. Fault: This comes on when one or both battery packs are in a warning or fault state. See Troubleshooting on page 45.
Commissioning 1. Move the circuit breaker switch to the ON position to turn on the battery packs. If two battery packs are installed, both must be turned on at an interval of less than 30 seconds. 2. On both battery packs, make sure that the ON indicator is on. If it stays off, do not use the battery pack. Contact LG Chem or your distributor. 3. On the RESU Plus, make sure that either or both of the Pack 1 and Pack 2 indicators are on.
8 Troubleshooting Check the indicators on the front to determine the state of the battery pack. A warning state is triggered when a condition, such as with voltage or temperature, is beyond design limitations. The battery pack’s BMS periodically reports its operating state to the inverter. When the battery pack falls outside prescribed limits, it enters a warning state. When a warning is reported, the inverter immediately stops operation.
9 Firmware Update It is possible to update the BMS firmware. Use a memory card to update it. A new firmware may be available from LG Chem website or your distributor. Prepare a memory card with these properties. • The capacity of the memory card must not be greater than 32 GB. • The memory card must be formatted in FAT16 or FAT32. • It must have only one firmware file in the root directory. For details about supported memory cards, see Supported Memory Cards on page 52. 9.
Firmware Update 4. Press and hold the update button beside the memory card slot for more than 3 seconds. NN CO NK TIO EC O FF O N IT 5. The LED indicators flash in cycles for 1 minute at most until the firmware update is complete. Only the ON indicator comes on when the firmware update is successful. If it fails, the Warning indicator comes on for two seconds. Check the memory card and try again. If it persistently fails, contact LG Chem or your distributor. 6. Remove the memory card.
Firmware Update 9.2 Updating RESU Plus firmware 1. Turn off the inverter. 2. Open the flap on the left side of the RESU Plus. 3. Insert the memory card into the memory card slot. 4. Press and hold the update button beside the memory card slot for more than 3 seconds. 5. The LED indicators flash in cycles for 1 minute at most until the firmware update is complete. Only the ON indicator comes on when the firmware update is successful. If it fails, the Fault indicator comes on for two seconds.
