Overcurrent protection
AC overcurrent detection
To protect against overcurrent due to sudden changes in load, the compressor is stopped if the set value AC :
12.5A is exceeded in the AC section. In this case, the outdoor fan does not stop, and 170 seconds after operation
is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal
is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-
minutes delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and
cutting the power.
DC overcurrent detection
To protect against overcurrent due to sudden changes in load, the compressor is stopped if the set value DC : 23A)
is exceeded in the DC section. In this case, the outdoor fan does not stop, and 170 seconds after operation is
stopped, another try will be made. Seven retries are allowed. On the eight retry, a complete stop request signal is
sentto the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minutes
delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the
power.
Compressor protector control
If the temperature of the compressor chamber exceeds 114°C, the compressor is stopped. In this case, the outdoor
fan does not stop, and when the compressor chamber temperature decreases to 100°C three minutes after
operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop
request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this
time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the
plug and cutting the power.
Power transistor module protector
If the temperature of the heat-sink exceeds 90 °C, the compressor is stopped.
In this case, the outdoor fan does not stop, and when the temperature of the heat-sink decreases to 80°C 170
seconds after operation is stopped, another try will be made.
Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the
outdoor unit will remain stopped until reset is performed. At this time, the 3-minutes delay for control of the outdoor
unit will not function; therefore, do not cancel by removing the plug and cutting the power.
Also if the temperature of the heat-sink exceeds 100°C, a complete stop request signal is sent to the inddor unit,
and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minutes delay for control of the
outdoor unit will not function ; therefore, do not cancel by removing the plug and cutting the power.
Power factor module
If a voltage error (over 420V) is detected at power factor module output voltage, 170seconds the compressor is
stopped.
In this case, the outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made.
Three retries are allowed. On the fourth retry, a complete stop request signal! is sent to the indoor unit, and the
outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor
unit will not function; therefore, do not cancel by removing the plug and cutting the power.
Serial signals
Serial signals consist of all 96-bit signals.
If the outdoor unit does not receive a serial signal, it will stop approximately 30 seconds later. Note that this is true
only of normal operation; in test mode, it does not stop and operation takes place based on the test mode
commands.
Rotation abnormal detection of compressor rotation
If the position detection cannot be performed during feedback operation of compressor operation, operation of the
compressor stopped.
In this case, the outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made.
Seventh retries are allowed. On the eight retry, a complete stop request signal is sent to the inddor unit, and the
outdoor unit will remain stopped until reset is performed. At this time, the 3-minutes delay for contro! of the outdoor
unit will not function ; therefore, do not cancel by removing the plug and cutting the power.
