Checking and setting the voltage on a Miltouch™ machine

Setting the correct voltage to the processor is important for all Milnor machines. There is no exception for the touch screen, Miltouch, models. The Miltouch processor board is mounted to the touch screen and is accessed by pulling the stainless steel cover from the display and rotating the board so that it can be accessed.


Loosen the 2 screws on each side of the display panel as well as the one on the back as indicated in the pictures below.



Slide the stainless steel cover forward off of the assembly. You will be able to access the back side of the display by using the hinge on the left side of the assembly.
The panel will not be able to rotate open until the screw in the back (pictured above) is sufficiently loosened.



Insert your voltmeter leads into the 2 terminals of plug J4 as indicated below to check the voltage that is being supplied to the processor board from the power supply.


The voltage reading should be 12.80v DC. If the reading is not 12.80v you will need adjust the supplied voltage to the processor. 
The image below shows where on the power supply to adjust the voltage. Turn the screw clockwise to increase voltage. Try not to overshoot 12.8v to avoid damaging the processor or related components.
