Operation Details
CS-G93KE
g. Minimum Frequency Operation Protection
• When the compressor operates at less than 31 Hz for 40 minutes, the operating frequency will increase to
31 Hz for 2 minutes.

i. Low Power Supply Voltage Protection
• When the DC voltage supplied to IPM (Power transistor) is reduced to 169 ± 5V (CS-G93KE) or 160 ± 5V
(CS-G123KE) the compressor stops and restarts after 3 minutes.
• If within 30 seconds after restarting of compressor, the DC voltage is reduced to 169 ± 5V (CS-G93KE) or
160 ± 5V (CS-G123KE) again, the compressor will stop for 1 minute.
If this condition repeats for 7 times, all indoor and outdoor relays will be turned off; TIMER LED will blink and
F99 is displayed.
j. High Power Supply Voltage Protection
• When the voltage supply (AC) exceeds 295 ± 15 V (T
0
), the air conditioner stops and restarts automatically
when the voltage supply (AC) is below (T
0
- 5)V. However, waiting for 3 minutes is necessary for re-operation.
