LCM Error Codes

If an error condition exists, the front Panel LED will blink the number of times corresponding to the error code number, pause, then repeat. After the user acknowledges the generated error screen, the error number will appear on the bot- tom left-hand side of the main run screen, and the described blink sequence will continue. If more than one error is present, all will be presented, separated by commas. When the condition is cleared, the corresponding error number will be removed from the main run screen. If an error code is present, the machine will not dispense.
