IGBT built-in sensor error in A3-IPDU
This error code means IGBT built-in temperature sensor error.
Check connection of connectors CN06 on IPDU P.C. board and CN600 on I/F P.C. board.
If sensor is normal, replace IPDU P.C. board.
1. Misinstallation and misconnection of TE1 sensor
and TL sensor
2. Resistance characteristics error of TE1 sensor and
TL sensor
3. Outdoor P.C. board (I/F) error
Are installed positions
of TE1 sensor and TL
sensor correct?
Are connection
of TE1 sensor connector
and TL sensor connector
normal?
Are resistance
characteristics of TL
sensor and TE1 sensor
normal?
Correct installed positions of
TE1 sensor and TL sensor.
Correct connection of
connectors.
Correct connection of
connectors.
Check outdoor I/F P.C. board.
Defect
Replace
TE1 sensor: Outdoor heat exchanger temp sensor
TL sensor: Temp sensor between liquid tanks of outdoor PMV1/2
* See “Outdoor unit temperature sensor characteristics” on “8-9. Sensor Characteristics”.
This error code means detection of Open/Short of TL sensor. Check disconnection of circuit for connection of
connector (TL sensor: CN523, White) and characteristics of sensor resistance value. (See “Outdoor unit temperature
sensor characteristics” on “8-9. Sensor Characteristics”.)
If sensor is normal, replace outdoor I/F P.C. board.
This error code means detection of Open/Short of TO sensor. Check disconnection of circuit for connection of
connector (TO sensor: CN507, Yellow) and characteristics of sensor resistance value. (See “Outdoor unit temperature
sensor characteristics” on “8-9. Sensor Characteristics”.)
If sensor is normal, replace outdoor I/F P.C. board.
This error code means detection of Open/Short of TA sensor. Check disconnection of circuit for connection of
connector (TA sensor: CN104, Yellow) and characteristics of sensor resistance value. (See “Indoor unit temperature
sensor characteristics” on “8-9. Sensor Characteristics”.)
If sensor is normal, replace indoor P.C. board.
This error code means detection of Open/Short of TS1 sensor. Check disconnection of circuit for connection of
connector (TS1 sensor: CN505, White) and characteristics of sensor resistance value. (See “Outdoor unit temperature
sensor characteristics” on “8-9. Sensor Characteristics”.)
If sensor is normal, replace outdoor I/F P.C. board.
