I have had to reload parameters on my OM-a control, and for some reason when I switch to "edit" then "program", go up to the crt soft keys and hit the C.A.P. soft key, "READ" then when I hit the "input" button on the keypad to get the LSK to blink so I can send a program, the LSK does not blink. The crt says "DEPRESS SOFT KEY" like it never recognized the input button. What could be the problem that I am missing? Any help is greatly appreciated. Thank You
