4.3Scales in Excess of 2.5 Meters

Traverse the machine to fullest extent of travel including hand winding past any electrical limits or trip dogs.

Insert the set up tube into the reader head, allowing for a sufficient amount of scale to project from the reader head in order to fit the scale mounting brackets.

Assemble the angle bracket to the scale clamp (Refer to Figure 4.5). The jack plate is included in each bracket kit and will only be required if the machine mounting face is not a machined surface. Slide the assembly onto the scale, allowing approximately 10mm clearance from the end of the reader head.

Mark the position of the jack plate (if required) or the angle support bracket. Drill and tap the necessary fixing holes and assemble the bracket to the machine.

Remove the blank tube and the bracket assembly from the reader head. Drill and tap M8 x 18mm (USA 5/16 - 18 x 3/4") fixing holes. Fit the jack plate (if required) and secure to the machine. Assemble the scale clamp and the angle bracket to the jack plate but do not secure. Traverse the reader head as near to the bracket assembly as possible. Slide the set-up tube through the reader head into the scale clamp. Adjust the brackets into position and carefully tighten the screws. Check that the set-up tube slides through the reader head and into the scale clamp smoothly without any fouling or interruption.

Remove the set-up tube and traverse the machine to the full extent in the opposite direction. Remember the “full extent” is the absolute maximum travel up to the mechanical “dead stops.”

Check the overall length of the actual scale and measure from the outside edge of the scale clamp already fitted to the machine and mark the position of the scale on to the machine.

Slide the set-up tube into the reader head, assemble the remaining scale bracket assembly including the jacking plate (if required) and slide onto the tube.

Set the outside edge of the scale clamp level with the mark that indicates the overall length of the scale and mark the fixing position for the bracket assembly.
