Ersa ETS 330 wave pump

Hello everyone,

i recently got Ersa ETS 330 wave machine '94. I got it running and heaters and flux pumps are ok, but I have problem with 2nd wave pump. It runs for 10-15 sec and then shuts down with error message on display. I checked bearings and coupler but no luck. If anyone can send me some documentation on this machine that would be realy helpfull. Thank you.
