      Hi

      I'm looking (desperately) for the schematic diagram of Erskine systems control board of the feed motor of the Bridgeport 6F power feed mechanism. when I'm turning it on, the contactor that supplies the supply voltage to the control board, kicks in, but that's it. no further response. pushing the restart red button on the board, didn't helped either. I hope that you will be able to help me finding the schematic.

      Thanx.

            Schematics, test and set-up data for a typical version of the common Erskine drive board are in the files section of the BridgeportMill group on Groups.io. This should be a link to the group **LINK** . Join up and have a rummage. The Yahoo Group mentioned in older threads has now shut down having moved to Groups.io.

            So far as I'm aware variations between years and PCB identifier numbers are mainly due to different active components. The operation remains the same. But if doing your own repairs you need to verify the actual type number of the components.

            My view, unless you have a fair bit of experience with that type and vintage of motor driver is that its probably better to arrange for a professional repair and test. Whether via exchange or direct to people who do such work. I guess cost would be in the £100 – £150 region for a professional repair but you will know that it (should) have been properly checked out and any still functioning but coming to the end of their lives replaced along with the broken ones. The drive will be at least 30 years old so aging components must be expected.

            Alternatively you could get amodern drive board of suitable specification for similar money. But it won't be aseasy to wire in.
