Alarm
Logic
Cooling fin is over-heated (
≧
90
℃
with 260 sec elapse or
≧
93
℃
with 5 sec elapse)
Possible
Causes
①
Ambient temperature is high
(
>50
℃)
②
Inverter board fault
(
Fin temperature detection part
)
Trouble
Shooting
①
External operating temperature of the unit is up to 50
℃
.
Check external environment for short circuit of supply air from air cooled condenser coil.
Resume the operation once the environment is improved.
②
If there is no external factor, it seems to be inverter board fault. Replace inverter board.

Restart after 3 minutes standby (Permanent retry
)

E531
Alarm
Logic
Voltage between phases are unbalanced due to the deterioration of the power supply
environment.
Possible
Causes
Deterioration of power supply environment
Trouble
Shooting
Regardless alarm is generated, restart after 3 minutes standby. (Permanent retry
)
Operation continues if the external factor like lightening is improved.

E532
Alarm
Logic
Voltage in inverter becomes
≧
DC790V or
≦
290V due to power supply voltage
≧
AC 530V or
over, or
≦
AC300V.
Possible
Causes
①
Power supply voltage is over upper limit (
≧
535V), or under lower limit (
≦
300V).
②
Inverter board failure (Voltage detection part)
Trouble
Shooting
①
Check if the actual power voltage is within allowable range (300V
〜
535V
)
.
*
Provide the power supply within allowable range if it is out of allowable range.
Restart after 3 minutes standby. (Permanent retry
)
Operation continues if the power supply condition is improved.
②
If the power voltage is within allowable range, it seems to be inverter board fault. Replace
inverter board.
