Note(s)
Actual voltage value depends on multimeter characteristics:
±57 VAC for RXLQ-TATJ* and RXLQ-TBTJ*, ±115 VAC for RXLQ-TAYD* and RXLQ-TBYD*, and
±143 VAC for RXLQ-TAYC*, RXLQ-TBYC*, and RXYQ-TAYC*.
Cautions:
In case there is more than 1 compressor in a system (outdoor is multi outdoor
configuration) all compressor inverter PCBs will perform the power transistor check. In
such case, disconnect U/V/W fasten terminals on all compressors. Avoid accidental
touch of fasten terminals to short circuit or ground leak to casing.
To stop the power transistor check mode, change setting to default 2-28-0.
Output to U/V/W will also stop when outdoor unit main PCB decides standby mode of
inverter circuit.
Next time graph shows the different steps during the power transistor check mode.
