6013 Protection Control13.1. Protection Control For All Operations13.1.1. Time Delay Safety Control1. The compressor will not start for three minutes after stop of operation.13.1.2. 30 Seconds Forced Operation1. Once the compressor starts operation, it will not stop its operation for 30 seconds.2. However, it can be stopped using control panel at indoor unit.13.1.3. Total Running Current Control1. When the outdoor running current exceeds X value, the compressor frequency will decrease.2. If the outdoor running current does not exceed X value, the compressor frequency will return to normal operating frequency.3. If the outdoor running current continue to increase till exceed Y value, compressor will stop, and if this occurs 3 times within20 minutes, system will stop operation and OFF/ON control panel LED will blink (F16 error occurs).13.1.4. IPM (Power transistor) Prevention ControlA. Overheating Prevention Control1. When the IPM temperature rises to 95C, compressor will stop immediately.2. Compressor will restart delay 3 minutes when the IPM temperature decreases to 90C.If this condition repeats continuously 3 times within 30 minutes, system will stop operation and OFF/ON control panel LED willblink (F22 error occurs).B. DC Peak Current Control1. When the current to IPM exceeds set value of 53.5 ± 5.0 A, compressor will stop. Compressor will restart after three minutes.2. If the set value exceeds again for more than 30 seconds after the compressor restarts, operation will restart after two minutes.3. If the set value exceeds again for within 30 seconds after the compressor restarts, operation will restart after one minute. Ifthis condition repeats continuously for seven times, system will stop operation and OFF/ON control panel LED will blink (F23error occurs).13.1.5. Compressor Overheating Prevention Control• The compressor operating frequency is regulated in accordance to compressor tank temperature as shown in below figures.When the compressor tank temperature exceeds 112C, compressor will stop, and if this occurs 4 times within 30 minutes,system will stop operation and OFF/ON control panel LED will blink (F20 error occurs).09D 12DOperation Mode X (A) Y (A) X (A) Y (A)Heating 24.0 30.0 28.0 30.0
