Panels Update - Relese Notes 8/e (A and B)

*_Relese Notes 8/e (A and B) Drilling _*1. The keylock hole has been pre drilled to make sure the art work lines up 1.1 This hole has not been beveled inside as the method of doing it has only just been devised and missed the panel run. However the fix is not difficult. A fine grit conical grinding wheel does the job with no damage to the panel. 2. The switch spindle hole has not been predrilled due to the following issue: 2.1 DEC did an ECO to replace the selector switch. Instead of six positions starting at 12 o'clock and steps of 36deg anticlockwise going to 6 o'clock. (A type panel) They used a switch that started at 15deg anti clockwise from top centre (12 o'clock) and that goes in 30deg steps finishing 15deg short of bottom centre (6 o'clock ). Now the hole position no longer lies on the vertical line between top centre and bottom centre. Its offset to the right due to the crossing position having moved due to the change of angle. They then did something strange. They redrew the top and bottom lines between the 15deg position and what would have been the circle crossing point of the original descending vertical line. That made it worse. In the end they just drilled the hole very oversize and hid the line under the skirt of the knob. I only have a key and lamp board for an A type panel so I can't tell if when they changed to the new switch they moved it to the right to take care of the change of angle. So for B type I chose to draw the lines at the correct angles. A switch spindle located at the intersection of the lines would then move through the correct angles You can now drill the hole to suit your spindle position Rod Smallwood
