I have set up a PSX-4 for track sections and all appeared to be fine, I then bought another PSX unit and attached my NCE Switch 8 and Tortoise point motors. These NCE Switch-8 units were working fine with the Lenz LZV100 and LH100. As soon as I installed the PSX the NCE Switch8 ceased working.

I set up on my test bench a new set of kit to see if the problem could be resolved but as soon as I put the PSX unit into the circuit the new Switch8 ceased working.

I reset the NCE Switch8 to no avail and then rechecked all the connections, it had appeared that the PSX unit had zapped the NCE Switch8.

As a result I will have to use the NCE Switch8s direct from the Lenz controller but that leaves me with 2 questions:

1/ is this a known problem?

2/ how can I get my now faulty Switch8s back into serviceable condition?
