HELP! Brunswick GSX HV boards and CPU board problems!

[Ashl3y]

Hello,
We are a 10 lane alley we currently have 5 lanes down. Every 2 months we have a pair of lanes down due to HV/CPU/Table motors, its now gone to a different set every 2 weeks.

We currently have a cpu board that blows all it's fuses we've have sent the board off for repair got it back and it's done the same thing on a different pair of lane.

Lanes 3+4 the relays have gone on the RHS, I replaced the motor with a new one before they where gone and after we put the new one on it killed off the relays (sounds like the HV board to me)

When the boards go it always takes out the table fuses.

I'm wondering if we have the wiring setup for the lanes due to a few markings on our boards (the fuses are 250v 8a however the machines are marked 400v).

Here are some pictures hope someone can confirm this is correct.

Blue motor info (note the triangle and the upside down Y for voltages)

Grey motor info (sames info as above)

The booklet that came with the blue motors

Grey motor type 1, the new blue motors have the same type of connections

Grey motor type 2

Blue Motor type 2


As it says in the booklet that the 250v should have its terminals differently, have we got ALL our motor wired wrong and slowly killing off the lanes or are these wired up right?

If someone could post a picture of how their motors are that would be fab!

Thanks in advance, now back to work!

I can tell you that in the US our motors are wired like the right-hand drawing from your booklet you have shown. It appears yours are wired like the drawing on the left. I wouldn't have a clue as to how this should be wired in the UK.

same as Dave here, do you run at 50 or 60 hertz in the UK. Several years ago Dennis with Brunswick Tech Support had me change from the 8 amp fuses to a 10 amp fuse and it worked great here, you might want to give them a call before you try this since you are having board problems though.

Measure the incomming voltage on each phase to ground, and phase to phase. You might have to install buck transformers to lower it.

believe the phase to phase are at 51M ohms, 51M ohms and a lower one at 43 ohms (that's off the top of my head) for grey and 39M ohms all the way across for the blue ones. I have all the motors readings and a known damaged motor we have is 10M ohms off, unfortunaly we don't know the tolerences

What is a buck transformer? FORGET THAT google is my friend and we have one of these already

Old appliances run at 50hertz, modern day appliances/tech run at 60hertz. I should think the lanes run at 50hertz.
