9.3.3 Zero crossing detection error diagnosis and solution (E2)

Error Code

E2

Malfunction decision

conditions

When PCB does not receive zero crossing signal feedback for 4

minutes or the zero crossing signal time interval is abnormal.

Supposed causes

●

Connection mistake

●

PCB faulty

Trouble shooting:

Check if the connections and

power supply is normal?

Correct the connections. Turn on the
unit when the power supply is good.
