Is the
pressure equalized
during 3-minute delay
before startup?
Is there
any loose connection
or breakage of cable
connected to the terminal
of the compressor?
Under the condition of no pressure difference,
startup by test operation mode.
Check the data for 30 minutes before stopping
Save data for 30 minutes before stopping in Mente PC.
Is it
the unit with one
compressor
?
Can startup?
YES
YES
Check and save the data of
operating conditions.
Check the power source
voltage and correct it.
Check the version No. of
software. (Is it latest?)
Check whether the solenoid
valve SVO at the exit of
oil separator is open during
compressor stopping.
(Is the pressure equalized?)
Replace the cable.
(If there is a problem on
the terminal of compressor,
replace the compressor.)
Wait and see
2. Error detection method
When it fails to change over to
the operation for rotor position
detection of compressor motor.
(If the compressor speed cannot
increase 11rps or higher)
3. Condition of error displayed
If the compressor fails to startup
for 20 times (10 patterns x 2
times) continuously.
4. Presumable cause
• Anomalous voltage of power
source
• Anomalous components for
refrigerant circuit
• Inverter PCB anomaly
• Loose connection of
connector or cable
• Compressor anomaly (Motor
or bearing)
Note:
*3 Measurement position: B and - of C19
*4 Measurement position: Check resistance between P-U, P-V, P-W, N-U, N-V, N-W, P-N. (Disconnect wires from compressor beforehand.)
If it fails to repeat, connect the Mente PC, and continue to collect data.

Is there inverter output?
Is DC15 V detected on

Check inverter PCB for
defect with the checker.
Check resistance between
power transistor modules.

Does it start up?
Change wire
connections on inverter
and compressor,
and operate again.
Does it repeat
on other
compressor?
