CAUTION
Before measuring the compressor motor windings resistance, measure the
resistance of the multimeter probes by holding the probes against each other. If the
measured resistance is NOT 0 Ώ, this value MUST be subtracted from the measured
winding resistance.
4
Measure the resistance between the compressor motor windings U-V, V-W
and U-W.
Result:
All measurements MUST be 1.114±5% Ω and equal.
Compressor motor winding
measurements are correct?
Action
Yes
Continue with the next step.
No
Replace the compressor, see
5
Measure the continuity of the U, V and W wires between the compressor and
the PCB. If no continuity, correct as needed, see
232].
6
Install the compressor wire terminals cover.
7
Install the compressor insulation.
8
Turn ON the power using the respective circuit breaker.
9
Start the unit operation via the user interface.
CAUTION
NEVER operate the compressor with the compressor wire terminals cover removed.
10
Wait for – or create condition to operate the compressor.
11
Once the compressor operates, measure the U-V-W inverter voltages.
ALWAYS measure at the PCB side.
Result:
All measurements MUST be the same.
