Selectivity adjustment The CC MC and Defender products utilize a selectivity potentiometer to accommodate a wide range of coin alloys and distributions among each alloy The selectivity adjustment allows the user to set the Comparitor to a more discriminative setting if a closely matching fraud is encountered or set to a more open setting to accept a wide range of poorly matching coins Turning the potentiometer clockwise on the CC and MC product sets the product to a more discriminative setting counterclockwise for Defender Turning the potentiometer counterclockwise on the CC and MC products allows the mechanism to accept a wider range of a poorly matched coin alloy clockwise on the Defender The factory potentiometer setting is typically set at a 9 00 o clock position arrow pointing straight left for most coins To set for the best performance acceptance of good coins coins which match the sample resident coin start with the pot at its most discriminative setting Turn the pot back counter clockwise clockwise for Defender in short increments dropping coins frequently between turns until all coins are accepted repeatedly Fine tune as necessary to accept all good coins or tokens and reject fraud coins Page 15 of 51 G Doc 0930Documents 09300348 Customer Test Station Rev 1109300348 Customer Test Station User Manual doc AIR BALANCE PROCEDURES FOR THE IC INTELLIGENT COMPARITOR USING THE COMPARITOR TEST STATION P

Rev 1109300348 Customer Test Station User Manual doc DETAILED PROCEDURE FOR AIR BALANCING THE SENSOR COILS USING THE COMPARITOR TEST STATION INTRODUCTION Air balancing the sensor coils is one of the most important adjustments made to the coin Comparitor Air balancing simply means to adjust the gap between the coils to create an electrical field that is equal in both coin slots It is important to adjust both coil sensor screws on the CC product line to an equal depth into the sensor coil body By following this procedure a uniform magnetic field will be maintained in the sensing area Coin travel and sensing metal content of coins and tokens can be made more accurately In addition proper rail insert adjustment will complete the air balance procedure by providing a means to match the resident coin to the falling coin so they eclipse in the sensor coils There is no rail adjustment on the Intelligent Comparitor product line Another performance related adjustment is the selectivity potentiometer Proper selectivity adjustment will improve coin token acceptance vs slug rejection Pages 31 35 illustrates the input output pin assignments for the various Coin Comparitors that Coin Mechanisms Inc manufactures WHY AIR BALANCE THE SENSOR COILS 1 After installing a new sensor coil assembly into a Comparitor 2 After installing a rebuilt sensor coil assembly into a Comparitor 3 Typical maintenance procedure for optimum performance
