Machines with rf engine crash

[kill05]

I've been trying to use the machines from the mod with an rf engine, but if i give them energy with any source exept for the mod generator it crashes my game. Sadly, if this doesn't get fixed i won't be able to use this mod. Thanks in advice.

Also if i take the rf engine out the machine the game crashes and as soon as i load the world it crashes again
