Hello,
We are having problem learning floors on a 15 stop 500 Ft/min gearless job DC-SCR. We have the 166628G01 board. We went through the steps to ensure tachs are calibrated and inspection speed is 78 Ft/min. as per instructions. The shaft signals seem to be correct. We do a learn run and the display increments a floor ahead and we run until the car stops just past the top floor. The scale plate value is 254 (book says 250 +/- 5). Just at the end of the run we get a fault "overspeed". We reset power and the car levels into floor, all looks good. We then put in a call, say 5 floors away. The car does not even reach full speed, slows at next floor and shuts down with "overspeed". Obviously it is not overpeeding. We have changed out the pulse board, speed reference board, and tachs. Still problem is there! Any help would be appreciated!
