Thickness & Diameter Adjustment
For The X-60 X-Mark Xeptor
 

Introduction (… AND why THIS is important) 
The X-60 Xeptor significantly raises the ability to measure and discriminate between coins through precision optical diameter measurement sensors, edge and center of coin metal alloy measurement, and X-Mark optical sensors to read minted-in codes on the surface of the coin. To benefit from these new measurement capabilities we must also do a little better in coin position control than formerly required when only metal alloy was being measured. One cannot expect imprecise coin position control to allow precise and repeatable measurement of the coin properties any more than one could expect an accurate measurement of the length of a fish if you won't put the ruler up against the fish. You can't measure a floppy fish!

Diameter Setup
The X-60 Xeptor has been designed to incorporate field adjustable coin chute width rails (see picture to the right) as a means for adjusting the coin chute width to optimize performance for a wide range of coin diameters. In order to properly read the X-Mark optical code, read both the edge and center metal of a bimetal coin, or to properly measure the diameter of the coin, it is imperative that the coin be reasonably centered in the coin chute a reasonably presented in a repeatable manner form coin to coin.    

IDX provides a Coin Chute Alignment Guide, as shown to the lower right, to aid in proper positioning of the coin chute width rails. As can be seen on the graphics of the Alignment Guide, there are groups of precision milled slots, sets for two different sized coins, on each its four sides. To adjust the coin chute width rails follow these steps:

  1. Use a 1/4" nut driver to loosen the four nuts that fasten the coin chute width rails on the rear side of the X-60 as indicated by the yellow arrows in the figure to the lower right. Make sure they slide freely. (Note: Some nut drivers have a thick barrel diameter making removal of the rear circuit enclosure lid helpful for getting the driver on the nut.)

  2. Identify the slots in the Coin Chute Alignment Guide associated with the size / denomination of token you wish to set the X-60 to accept.

  3. Position the Coin Chute Alignment Guide on the X-60 as shown in the figure to the right so that the left most slot, marked "Xeptor Frame", slips over the left side of the X-60 metal frame.

  4. Position the left and right coin chute width rails to slip into the two slots identified in Step 2 for the coin you wish to accept.

  5. Push the Coin Chute Alignment Guide down onto the X-60 so that the Xeptor frame and the two coin chute width guides are deep into their respective slots.

  6. Make sure the coin chute width guides are fairly vertical in alignment from top to bottom, then tighten the four nuts.

  7. Remove the Coin Chute Alignment Guide and check to see if your coin fits well in the coin chute without too much slop in the fit.

 

Thickness Setup
The X-60 Xeptor side view figure below shows a series of three holes and a sliding adjustment with a detent that centers itself over one of the selected holes. The dimensions referring to each of the eight holes is the chute thickness achieved at each position of the sliding adjustment. A good rule of thumb would be to set the adjustment for about 0.010" to 0.020" more than the thickest coin you intend to accept. If you go under .010", you risk the possibility that a bent coin, one with a bur, or one that has something sticky on it will jam in the coin chute. If you go over .020" then you are starting to sacrifice the accuracy to which the metal alloy can be discriminated. Recommended positions for the thickness setting are marked in the table below, and on the reverse side of the Coin Chute Width Alignment Guide.
