Hi,

I asked the 3 phase support team here and below is the response.

0 2 2

Inverter/Bypass control in Init. state

PFC control in Off state

Charger control in Off state

00001038

20000000

00000080

05

Fault present, PFC, Inverter & Charger locked

DC-Bus voltage sensor fault

Second DC-bus voltage sensor fault

No batteries present in system

Looks like the power module has a DC Sensing problem and may need to be replaced.

They can try cycling power to the power module by putting UPS in manual bypass, (if the have an external bypass cabinet), and then cycling power to the UPS.
If the fault remains they will need to replace the power module.

If you need further assistance you should contact local support. Here is a link to their information.

Hello Bill,

Can you guide me step by step how to cycling power to the power module by putting UPS in manual bypass?

One more thing, please also provide the procedure to replace the power module as well.
