Applicable Models
ER*Q 011~016*
Method of
Malfunction
Detection
Inverter PC board takes the position signal from UVW line connected between the inverter and
compressor, and the malfunction is detected when any abnormality is observed in the phase-current
waveform.
Malfunction
Decision Conditions
This malfunction will be output when the inverter compressor motor does not start up even in forced
startup mode.
Supposed Causes
Compressor lock
High differential pressure (0.5MPa or more)
Incorrect UVW wiring
Faulty inverter PC board
Stop valve is left in closed.
Troubleshooting
Check the installation
conditions.
Is
the stop valve
open?
NO
Is the UVW wiring
normal?
NO
NO
NO
NO
Is high
differential pressure starting?
(0.5MPa or more)
YES
YES
YES
Check and see
whether compressor is
short-circuited or
ground.
YES
YES
Are
inverter output
voltages the same for 3
phases?
Does low or
high pressure vary
even instantaneously when
restarting compressor?
YES
Caution
Be sure to turn off power switch before connect or disconnect connector, or
parts damage may be occurred.
Open the stop valve.
Connect correctly.
Remedy the cause.
Replace the compressor.
Replace the inverter PC board
Assy (A2P).
Replace the compressor.
