I have a Haas Super Mini Mill that is powered by a phase perfect electronic phase converter.
I live in a cold part of the country and last winter I started having problems getting my mill to power up when outside temps would drop.
My theory is that when the outside temps start dropping that the power demand increases at my utility company from everyone's electric furnaces kicking in..... and this may be dropping my voltage coming from my panel.
The mill powers fine in the summer months, so this fall I started monitoring my voltages and sure enough the past couple of days when our temps started dropping my machine has issues powering up.
Just to clarify.... the room that the machine and phase converter is warm ( 65 to 70 degrees )
Here are my voltage numbers
Attachment 431030
I currently have my manufactured leg from the phase converter going to the center terminal on the Mill which would be L2
Currently I have the jumper on the T5 24v on the mill set on the top jumper which is set for range of 221 - 240
Do you think I should move it down to the 190 - 220 slot for the winter months ?
Thanks,
Kent
