Operation Details
CS-G93KE
B. PROTECTION
1. PROTECTION CONTROL FOR ALL OPERATIONS
a. Time Delay Safety Control
• The compressor is not restarted for 3 minutes after stop of compressor.
b. 30 Second Forced Operation
• Once the compressor is ON, it will not turn OFF for 30 seconds. However, it is turned off by remote control
or Automatic switch.
c. Total Running Current Control
• When the outdoor unit total running current (AC) exceeds I1, the frequency is lowered by 1 rank. If I1 is not
exceeded for 30 seconds, the frequency is highered by 1 rank at one time. If the outdoor unit total running
current exceeds I2, the compressor is immediately stopped for 3 minutes.

• If the outdoor unit total running current exceeds I2 3 times within 30 minutes, all indoor and outdoor relays will
be turned off ; TIMER LED will blink and F98 is displayed.
d. IPM (Power transistor) Prevention Control
1. Overheating Prevention Control
• When the IPM (power transistor) temperature rises to 100 ± 10°C, the compressor stops immediately. The
compressor is restarted when the IPM (power transistor) temperature decreases to 90 ± 10°C after 3 minutes
(Time Delay Safety Control). If this condition occurs 4 times within 40 minutes, all indoor and outdoor relays
will be turned off; TIMER LED will blink and F96 is displayed
