8.2.7. IPM (Power transistor) Prevention Control
This control is applicable to all kinds of operation mode.
A. DC Peak Current Control
1. When electric current to IPM exceeds set value of 22.5 ± 3.5 A, the compressor will stop operate. Then, operation will restart
after three minutes.
2. If the set value is exceeded again within 30 seconds after the compressor starts, the operation will restart after one minute.
If this condition repeats continuously for seven times, all indoor and outdoor relays will be cut off.
B. Overheating Prevention Control
1. When the IPM temperature rises to 110°C, compressor operation will stop immediately.
2. Compressor operation restarts after three minutes the temperature decreases to 95°C.
8.2.8. Compressor Overheating Prevention Control
This control is applicable to all kinds of operation mode.
Instructed frequency for compressor operation will be regulated by compressor discharge temperature. The changes of frequency
are as below figure.
8.2.9. Low Pressure Control (Gas Leakage Detection)
This control is applicable to all kinds of operation mode.
1. When the conditions listed in below table occur, the compressor stops and restarts after three minutes.
2. If this phenomenon is continuously occurring for twice within 20 minutes, all indoor and outdoor relays will be cut off.
3. This control is not applicable for deice operation.
