OK, thanks for all input.
This morning I wired as per Mathews directions.
you were right - the cable with the blue wire went to motor . . . .
so, got it all wired up, turned on power and shutter moved into its fully down position (it was stuck up a couple of feet)
when the switch was operated in one direction nothing happened, in the other the shutter moved a little, before reversing back to fully down.
as the scaffold was currently set up against the shop glass I had to abandon it for now so the plastering could continue - but clearly somehting is not right!
