Malfunctions
Overview
This chapter contains the following topics:
3.12.1 Sensor Malfunction Detection
General
Sensor malfunction may occur either in the thermistor or current transformer (CT) system.
Relating to
thermistor
malfunction
P
Outdoor heat exchanger thermistor
P
Discharge pipe thermistor
P
Fin thermistor
P
Outside air thermistor
Relating to CT
malfunction
When the output frequency is more than 55 Hz and the input current is less than 0.5A, carry out
abnormal adjustment.
3.12.2 Detection of Overload and Over Current
Outline
In order to protect the inverter, detect an excessive output current, and for protecting compressor,
monitor the OL operation.
Detail
If the OL (compressor head) temperature exceeds 120~130°C (depending on the model), the
compressor gets interrupted.
If the inverter current exceeds 30 A, the compressor gets interrupted too.
