Mitsubishi vrf inverter board dip switchs

[Paultighe]

Hey folks, anyone know what the dip switches on just the compressor inverter board 1 to 4 are used for, possibly self test ? ?

If you send me a pm with you e mail address I can send you the service handbook, should be in there!

If you want to test the inverter output without the compressor connected to ensure the inverter has correct output
then
you need to put SW1-1 to ON possition.
This will stop the inverter reporting low amps fault & allow you to take readings.
but
its a bit like the test run function it counts down a time period & then switches unit off to prevent the unit being left permanantly in this test condition.

Cheers handy, the very first vrf units would run the inverter with the compressor tails disconnected.
