Okay to let TB return to idle with LN-25?

[walker]

I run an LN-25 off my TB5251 and have been for some years. My return to idle circuit has been down for much of that time, so I just leave it in run. I am fixing my return to idle circuit and am wondering if it is okay to allow the machine to run at idle with my LN-25 connected. I know it will return to idle if I pull the sense lead, not sure if it will with it connected, just don't know if it is healthy for the LN-25 to do so, and due to the cost of circuit boards though it wise to ask.

Thanks,
