Mecc Alte Alternator voltage not stable after changed to 60hz?

[merryengineer]

Hi,

I have just changed the speed of my generator to 60hz and now the frequency is not stable?
What can I do?

When you change from 50 to 60Hz, you need to set the stability pot on the AVR again.

** Caution, the AVR is live when the machine is running, only adjust it when the set is off. **

Turn the STAB pot all he way anti-clockwise, then adjust it clockwise until the voltage becomes unstable.
Then turn it back about 10 degrees.
