Part 4 Functions and Control
2.6.3 Discharge Pipe Protection Control
This discharge pipe protection control is used to protect the compressor internal temperature
against an error or transient increase of discharge pipe temperature.
2.6.4 Inverter Protection Control
Inverter current protection control and radiation fin temperature control are performed to prevent
tripping due to an abnormality, or transient inverter overcurrent, and fin temperature increase.
Inverter overcurrent protection control by primary current [CTi1]
Normal control
Discharge pipe temperature > 135°C
Discharge pipe
temperature < 95°C
Discharge pipe
temperature > 108°C
Reduce compressor capacity step
Discharge pipe temperature standby
When occurring 3 times within 100
minutes, the error code
F3
is output.
