COMPRESSOR AND ANOTHER ELECTRIC COMPONENTS
[_ Power Source H
Separate the PTC-STARTER from
the Compressor and measure the
voltage between M and C of the
Compressor.
The applied voltage is not in the
range of Rating Voltage + 10%.
Equal to the applied
voltage, (Rating
voltage + 10%)
H dvice the customer
to use in the
specified range.
Check the
resistance of the
Compressor Motor.
H Test the resistance among
M-C, S-C, and M-S.
Replace the Compressor.

Check the
starting state.
Measure minimum starting voltage
after checking steps 1-3 above,
Measure the pressure balance of
the PTC at the interval of more
than 5 min.

Normal.
Starts at the voltage of
more than 90%.
Check the starting
state at the regular
voltage above.
NO
Replace the PTC.
