Function and Control
Detail
I Judgment by power consumption
When an output frequency is exceeds 55 Hz and the input current is less than specified value,
the adjustment is made for insufficient gas.
II Judgment by discharge pipe temperature
When discharge pipe temperature is 20°C higher than target value and the electronic expansion
value opening is 450 pulses (max.), the adjustment is made for insufficient gas.
III Judgment by the difference of temperature
When the difference of the temperature is smaller than
, it is regarded as insufficient gas.
