Mars coin changers use sensors to accept legitimate coins and reject others.
When customers place coins into the Mars coin changer, sensors measure the diameter, thickness and material of each coin, rejecting coins that do not match the coin acceptance parameters. If accepted, the acceptance gate opens and transmissions of information take place, ending with change given back to the customer when necessary. The Mars coin changer assists you in troubleshooting, so you know generally where to start looking for the problem and help get the vending machine up and running more quickly.
Instructions
1. Check to make certain you have the Mars coin changer connected to an electrical outlet and powered on if you see the LED off. Locate the LED on the keypad, which informs you of the coin changer status with flash codes.
2. Clean the Mars coin changer if you see one LED flash by first turning off the power of the coin changer while it sits in the machine, then opening the acceptor lid. Clean the coin ramp, groove and areas around the lid using a damp cloth and mild detergent. Clear out any debris in the accept gate area located underneath the closed acceptor lid. Close the acceptor lid and turn on the power.
3. Clear out a strobe sensor blockage if you see two LED flashes, by squeezing the blue chips together to remove the coin cassette, then loosening the fixing screw located above the keyboard displaying the LED flashes. You should be able to tilt the acceptor assembly in a forward position. Lift up the acceptor and take it out, and then disconnect the gray-colored, 26-way ribbon connector. Locate, then disconnect the 7-way ribbon connector on the back side of the acceptance assembly, as well as the two multi-colored wire connectors next to it. Unthread the two multi-colored wires and ribbon to remove the separator from the acceptor. Locate the clips on the left side as you look at the front of the acceptor, and then carefully pry the clips until you can unhinge the separator from the acceptor. You can get to the coin accept slot once you have removed the separator. The strobe sensor blockage error you saw means a jam exists around the coin accept slot area. Clear out jammed coins and debris from this area, then reassemble the coin changer.
4. Remove the tube cassette and clear out all the jammed coins you can locate from the top or bottom of the tube at the exit slot if you see four LED flashes. Make certain you do not see a deformed coin at the bottom of each tube, which would cause jams. Clear the LED error by depressing any blue key, and then return the cassette into the Mars coin changer.
