  • 8270 stuck in NPR mode

    been looking around but can't find ANY earlier posting re: a "NPR" problem on 8270's. I'm pretty sure that's what i'm dealing with right now. Machine will NOT cycle.......sweep will NOT run pressing sweep run on chassis.........will NOT run engaging SA............will NOT run engaging sweep run toggle switch on Mgr control box either. ONLY power to sweep motor is through relay in chassis. I've removed the wires from terminals 5 & 6 in A&MC box and problem is still there. Any ideas ??? Thanks...
