13.10 TROUBLE SHOOTING
When a coin is inserted into the coin acceptor, the coin should roll down the coin path and drop into the coin vault if the
validating process is successful. The onboard display will show the coin value.
During the initial setup, if the coin does not fall into coin vault, make sure the machine is level and all the settings are carried
out properly or repeat the teach mode.
If the coin does fall into the coin vault but system does not register the signal, check the requirement of the host system and
make sure SW1 & SW2 is switched to the correct position as well as the coin value and price are correctly set.
