How to Identify the Failure Cause of E0.13 (DCBL controller Error) and E0.57 (Fan
Inverter Error) and Check the History
Note : DCBL controller is equipped with Vtype.
Fan inverter is equipped with air-cooled type.

(a) Controller shutdown code
If the shutdown code “XX” is “
,” it indicates that
there is no shutdown history. Also, when anything
other than shutdown history is displayed without
shutdown resetting, the display is return to the latest
shutdown history in 3 minutes.
IMPORTANT
For the shutdown history of controller, only the most
recent shutdown is recorded. Shutdown history is
displayed in shutdown codes.
