OUTDOOR UNIT OUTDOOR UNIT Error Method: Error Method:
EEPROM ERROR
Detective Actuators: Detective Actuators:
Outdoor unit Control PCB
Detective details: Detective details:
When the access to the external memory (EEPROM) is failed due to some
cause (External Noise, defective component,etc.) upon Outdoor Unit start
– up. After the error occurred, the operation of Outdoor unit is not limited.
1)Check the supply voltage AC220V between (L) and (N)
If AC does not appear, check the circuit at power supply side.
2)Check the wiring of connection cable (incorrect wiring / loose connection, etc.)
If there is incorrect or loose wiring, turn off the breaker and conduct rework.
Check Point 2 Check Point 2 - - 1 : Check Power cord Connection 1 : Check Power cord Connection
Forecast of Cause Forecast of Cause:
1.Relation of installation construction 2. Relation of unit
1) Use of specified material 1) Check the Power POWER CORD
2) Power supply circuit (voltage drop/ Noise etc.) 2) Check Control PCB(Component failure)
Check Point 2 Check Point 2 - - 2 : 2 : Check Outdoor Unit electrical components. Check Outdoor Unit electrical components.
Check connection, removal and incorrect wiring of all the connectors.
Check if any shorted mark or corrosion on PCB
When Control PCB is defective, replace it.(If Dip SW was changedconduct resetting DIP SW.)
Check Point 1 Check Point 1 - - 2 : Check Power supply 2 : Check Power supply
Check external cause (Power supply)
Instant Drop Check if there is an electric equipment with a large load in the same circuit.
Instant Power Outage Check if there is a defective contact or leakage in the power supply.
Noise Check if there is any equipment that cause the harmonic wave near the power line.
(Neon tube or Electric equipment that harmonic wave Check that the grounding is completely insulated.)
