Troubleshooting
5-3-9 (M) Check of instantaneous over-current protection of inverter circuit.
Inverter instantaneous over- c u r rent protection mode is the mode to be actuated in order to
p revent the damage of elements from the peak current of inverter circuit elements.
In case that the inverter circuit instantaneous over- c u r rent protection mode actuates.
(condition of installation)
♦
The ventilation is not good because the outdoor unit is installed wrong (the ambient tempera-
t u re 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 overc h a rged.
-> 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 simultaneously the inverter control board and the power TR.
5-3-10 (N) Check of the comp Top OLP and discharge gas temperature abnormal rise.
If the comp top temperature and the discharge gas temperature rises higher than a certain level,
it protects the circ u i t .
If the comp top OLP t e m p e r a t u re and the discharge gas temperature rises abnormally,
(Condition of installation)
♦
The ventilation is not good because the outdoor unit is installed wrong (the ambient tempera-
t u re 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 insufficient.
-> Fill up the amount of re f r i g e r a n t .
If only the inverter control board is replaced with the state the power TR. is damaged, the control board is damaged again.
(Same as for the vice versa of the above.)
