Your ETS Switch needs to move closer to the floor. If the Print says it should be at 1'-8", place it at 1'-5". What happens is you are making an NTS stop for whatever reason, but you end up ETS stopping instead. To check that this is the problem. Set your Service Tool up for a Buffer test in either direction, but don't jump out any switches. You will most likely Buffer out. Then move the Switches and repeat the Buffer Test. You should make a regular NTS Stop.Good Luck
