4. TROUBLESHOOTING [Protective Device]
■ 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.

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.
IMPORTANT
If the shutdown code "XX" is "
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.)
Probable cause
Lock of main motor
Rapid acceleration/deceleration
Overload of main motor
Excessive voltage of power line
Reduction of receiving voltage, IPS
Reduction of controller fan revolution, disconnection of controller fan wiring
Cooling fi n, air intake hole, clogging of cooler, high ambient temperature
Electrical noise
Cooling fi n, air intake hole, clogging of cooler, high ambient temperature
Probable cause
Lock of fan motor
Rapid acceleration/deceleration
Overload of fan motor, restart immediately after stop
High receiving voltage
Exogenous noise, temperature increase
Low receiving voltage
Between output and fan motor
Receiving voltage is higher than specifi ed.
Cooling fi n, air intake hole, clogging of cooler, high ambient temperature
