Corresponding measures
Please contact with local dealer if error remains the same after
several reset.
1.Disconnect the input/output switch, check the AC-side wiring
and reseat the plug to rule out bad contact.
2、Please contact with local dealer if error remains the same
after several reset.
1.Disconnect the input/output switch, check the AC-side wiring
and reseat the plug to rule out bad contact.
2、Replace switch;
3 、 After electricity grid returns to normal, the machine will
automatically restart;
4、Please contact with local dealer if error remains the same
after several reset.
