① Press the SELECT/WIDE button 14 times. "E6." and "E7."
are shutdown history of DCBL controller.
② Press the RESET button. The indication on digital monitor
returns to discharge pressure display.
■ 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.

E05 Overload Activation of electronic thermal Overload of main motor
E07* Overvoltage Excessive voltage of the converter Excessive voltage of power line
E09 Undervoltage Voltage below the specifi ed level Reduction of receiving voltage, IPS
E10 CT error CT error
E20 Temperature trip Controller fan error
Reduction of controller fan revolution, disconnection of controller fan wiring
E21 Temperature trip Overheat of cooling fi n
Cooling fi n, air intake hole, clogging of cooler, high ambient temperature
E22* Communication error 1 Communication error in controller Electrical noise
E23* Gate array error Gate array communication error
E24 Phase lacking Phase lacking
E30 IGBT error Occurrence of instantaneous overcurrent
E33 Communication error 2
Communication error between controller and PC board
Electrical noise
E35 Main motor overheat Excessive temperature of main motor
Cooling fi n, air intake hole, clogging of cooler, high ambient temperature
(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.
(
See the shutdown code list in this page.)
