We have a CL-20 w/Fanuc 21T control. I was looking through our ladder and found there are 2 different "Manual Door Types", Types B2 and B3. Type B2 is active if only D145.1 or D146.1 is on (1). Type B3 is active when both are on (1). These may not be the same on your machine though.
You should be able to compare your D parameters by going to the PCDGN screen and searching for D145 on both machines. You could also try looking in your Ladder Diagram manual for the D bits labelled ILKRLS1.P & ILKRLS2.P
If you need information on editing the D parameters, message me and I'll try to help you.
