6-3-11 (L) Check of instantaneous over-current protection of IPM circuit.
√ Inverter instantaneous over-current protection mode is the mode to be actuated in order to prevent the damage of elements from
the peak current of IPM circuit elements.
√ In case that the inverter circuit instantaneous over-current protection mode actuates.
■
Condition of installation
■
• The ventilation is not good because the outdoor unit is installed wrong (the ambient temperature is higher than 50 (°C) )
■
• → Reinstall the outdoor unit so that the good ventilation can be made.
■
• In case that the operation is made with the cover bent of the outdoor unit.
■
• → Take out the cover.
■
• If two outdoor units are operating face to face, (the bad ventilation is made)
■
• → Reinstall the outdoor unit for the good ventilation.
■
• The air circulation is bad due to the attachment of falling leaves.
■
• → Take away the leaves for the good ventilation.
■
• If the Refrigerant is overcharged.
■
• → Check the amount of Refrigerant.
■
Unit defect
■
• If the comp is locked.
■
• → Replace the comp.
■
• If the comp is operating without the revolution of fan motor.
■
• → Check the fan motor connector and replace the fan motor.
■
• In case the parts of the control board is damaged.
■
• → Replace the outdoor control board.
6-3-12 (M) Check of the comp discharge gas temperature and OLP temperature abnormal rise.
√ If the comp discharge gas temperature and OLP temperature rises higher than a certain level, it protects the circuit.
√ If the comp discharge gas temperature and OLP temperature rises abnormally,
