When PID operation or frequency given by analog signal, although it seems constant speed, acceleration and deceleration could be repeated in very short cycle. On Multizone systems only, if LD 301 is lit permanently and LD 302 is flashing a number of times, this indicates a thermistor fault. Refrigerant Leakage. 51InverterAbnormality of Current Sensor for InverterFailure of Sensor on Inverter PCB 52InverterOvercurrent Protection ActivatingOverload, Overcurrent, Locked to Compressor 53InverterIPM Protection ActivatingAutomatic Stoppage of IPM (Overcurrent, Low Voltage or Overheating) Monitoring Trip Events, History, & Conditions An error code will appear on the display automatically when a fault causes the inverter to trip.

However, in most cases the help of a service engineer is indispensible. Tripping of Fuse.
The inverter trips and does not go into Run Mode until the error is cleared. Please try the request again. E38 Low-speed overload protection If overload occurs during the motor operation at a very low speed, the inverter will detect the overload and shut off the inverter output. Hitachi Ac Error Code E1 The following table lists the cause associated with the error.
A decrease of internal DC bus voltage below a thresh- old results in a control circuit fault. Hitachi Excavator Fault Codes Air inlet or coil thermistor not connected, open or short circuited faulty PCB 10Indoor fan motor over current or abnormal rotation speed. Check cable connections, cable is not short circuited or open circuit and PCB operation. Excessive electrical noise may be the cause.

E21 Inverter thermal trip When the inverter internal temperature is above the threshold, the thermal sensor in the inverter module detects the excessive temperature of the power devices and trips, turning E43 EzSQ invalid instruction The program stored in inverter memory has been destroyed, or the PRG terminal was turned on without a program downloaded to the inverter. E07 Over voltage protection When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor. Hitachi Ac Error Code E6 Check pump operation and drain 07Drain pump forced operation.
Excessive electrical noise may be the cause. Shut down the power after completing copy or initialization. *4 USP error occures at reseting trip after under-voltage error (E09) if USP is enabled. If LD 301 is lit in conjunction with LD 303 his indicates an overload (1) condition but not an alarm. Check This Out E08 Memory error *2,3,6 When the built-in memory has problems due to noise or excessive temperature, the inverter trips and turns OFF its output to the motor.
