Test Run How to Cope with Test Run Abnormality The phenomena from main component failure Component Phenomenon Cause Check method and Trouble shooting Compressor Outdoor fan Outdoor LEV Not operating Stop during running Loud noise during running High pressure error at cooling Heating failure, frequent defrosting No operating sound at applying power Heating failure, Frozen outdoor heat exchanger part Low pressure error or discharge temperature error 46 Outdoor Unit Motor insulation broken Strainer locking Oil shortage Motor insulation failure Phase sequence fault Motor failure, Bad ventilation around outdoor heat exchanger Bad connector contact Coil failure LEV clogged LEV clogged Check resistance between terminals and chassis Service necessary Open drain cock and check oil Check resistance between terminals and chassis Check wiring(R, S, T) sequence, or lnter change last two phase connection. Check the outdoor fan operation after turning the outdoor unit off for some time. Remove obstacles around the outdoor unit. Check connector Check resistance between terminals Service necessary Service necessary When system fault occurs, the error code is displayed at indoor unit display or remote controller display, the trouble shooting guide is in the service manual. Outdoor Unit Indoor Unit Remote controller
Self-Diagnosis Function Error Indicator Test Run • The function is to self-diagnose airconditioner and indicate the problems, if any. • Error mark is displayed on display window of indoor units and wired remote controller, and 7-segment LED of outdoor unit control board as shown in the table. • If more than two troubles occur simultaneously, lower number of error code is first displayed. • After error occurrence, if error is released, error LED is also released simultaneously. Indoor unit related error Power related error Compressor related error Display Title Cause of Error 0 1 Indoor unit air sensor Indoor unit air sensor open or short 0 2 Indoor unit sensor(inlet pipe) Indoor unit inlet pipe sensor open or short 0 3 Wired remote controller ↔ indoor unit transmission In the case that indoor unit can not receive any signal from wired remote controller successively for 3 minutes 0 4 Drain pump Malfunction of drain pump 0 5 Outdoor unit ↔ indoor unit transmission In the case that indoor unit can not receive any signal from outdoor unit successively for 3 minutes 0 6 Indoor unit outlet pipe sensor Indoor unit outlet pipe sensor open or short 0 7 The other operation mode In the case that an indoor unit is operated the other operation mode different from the operated indoor unit 0 8 Not in use Not in use 0 9 Serial No. Error In the case that the serial number marked on EEPROM of indoor unit is 0 or FFFFFF 2 1 DC peak IPM over temperature or compressor malfunction is occurred 3 times in 1 hour 2 2 Max CT When current detection is over the maximum current limit 2 3 DC link DC charging is not performed for 45 sec after starting relay turn on 2 4 High pressure Compressor is OFF 3 times in 1 hour due to high pressure 2 5 Low/Over voltage Input voltage is out of tolerance of rating voltage 3 3 3 3 3 1 2 3 4 5 Not in use Discharge temperature (inverter compressor) Discharge temperature (constant speed compressor) High pressure Low pressure Not in use Due to over rising of inverter compressor discharge temperature, Compressor off is occurred 3 times in 1 hour Due to over rising of constant speed compressor discharge temperature, Compressor off is occurred 3 times in 1 hour Due to high pressure, Compressor off is occurred 3 times in 1 hour Due to low pressure, Compressor off is occurred 3 times in 1 hour Installation Manual 47 ENGLISH
