Thread: Error 39 on FP2NC dialog 4

Ok, my machines been off for a few months, and as usual, it doesn't like that!

My manual says error 39 is a hardware error in the NPP90. Tomorrow, I can reseat that and check the connectors. Never had this problem before.

Does anyone have any insight into this??

regards,

Jon P.

I can't help you on the error, but if I am not going to be using my FP2NC/D4 for a while, I try to power it up for a couple hours once a week, just to keep the batteries charged, pump some way oil around, and spin the gears and bearings. The longest I've ever left it unpowered is about two weeks. Knock on wood, the machine has been very reliable since I replaced the rotary switch board in the console with Martin's help. I think that was a couple of years ago by now.
