its an oildraulic controller, the door board he is talking about is in the controller, it is part of the logic system, along with the power, car board etc. the door board has nothing to do with controlling the speed of the doors, the 2 pots are for door hold open times only. the 3 resistors in the controller are r1d, r2d, r3d r2d is the resistor that will control the open hi speed, this is probably the resistor that has the wire removed, it would be the wire that goes to the OHS relay contact. r3d is the resistor that controls open start speed, and close speed. it will have 2 sliders on it to adjust these speeds. r1d is a fixed resistor on the negative side of the power supply, and is fixed, no adjustment. i say that the resistor with the wire removed is hi speed, because if the OHS timer fails, or the mechanic can't adjust the hi speed of the door properly, this is sometimes removed. seen it a few times. if you say the doors don't decal properly, then you either have the overall speed set to hi, which case you would adjust the taps for open and close , or the slowdown resistor on the car top in the door operator is open, or some problem there. you can force the doors into slowdown by putting a jumper between CT, and the slowdown bands for each speed,
what i would do is take the slowdown wire CT off of the slowdown resistor, then set overall door speed to something that does not slam the doors open or close, then put ct back on and fine tune the slowdowns. slowdown cams should be set similar to gal same idea. if you need any prints i have some good luck
a properly adjusted door, would start to open slowly, about 1-2", then the OHS relay would pick up, which would initiate hi speed, you need to adjust the OHS timer in the controller, to adjust the slow start of the doors, along with the A band on the door operator i believe it is A
