You can find the firmware update for the 6000EX and the 6500EX on the eg4electronics.com site. However, before running the firmware update, it would be a good idea to double check your dipswitch settings. If they aren't exactly right you will get error 61. The firmware for the 6000EX is for intermittent error 61. If it is static, it is not a firmware issue. A lot of times people just have the comms cable backwards.
Take these steps for your 6000EX for 61 fix before firmware update.
- Ensure that the host battery has the correct dip switch setting. If you have to change this setting, power cycle the battery. (Lifepower4 = down, down, down, down / EG4-LL = down, down, down, up)
- All other batteries must have non-matching dip switch settings.
- Use the provided communications cable to connect the host battery to the host inverter. Pins 1& 2 go to the battery and pins 3 & 5 go to the inverter. Then use the short patch communications cable to interconnect the remaining batteries.
- Set the host inverter program setting 14 to EG4. If there are slave inverters, set them to USE.
- Go back to the main display screen. It may take a minute for the system to recognize the change. If the status does not change, Reset the system.
