Error Codes

If <enter> is pressed at the “Error Codes” prompt, the
controller will enter the error display mode. If no errors
have occurred since the last error reset, the display will
show “None.” If an error has been detected since the last

error reset, the display will show the first summary error

code that has occurred, such as “Vend Mechanism,” which
would indicate a vend error. Pressing <up> or <down>
will allow you to cycle through all of the summary error
codes that are present. Pressing <enter> at the displayed
summary error code will allow you to view the detailed
error codes beneath the summary error heading (see
below). Pressing <up> or <down> at this point will
allow you to cycle through all of the detailed error codes
that are present beneath the summary error code. If the
<exit> button is pressed anytime during this operation, the
controller will return to the “Error Codes” prompt. Press the
<up> button to proceed to the next prompt, “Coin Pay Out.”

If the <clear> button is pressed during the display of any
detailed error code, that error will be cleared. If other
errors exist that fall under the currently accessed detail
type, the next error would be displayed. If no other errors
of the current type exist, the next error summary code
will be displayed, or “None” will be displayed if no other
errors exist.

The error summary codes and their corresponding detailed
error codes are as follows:

•

Control System

By pressing <enter> at the “Control System” prompt,
the controller will display:
1. “Door Switch,” indicating the door switch has

been open for more than an hour;

2. “RAM Checksum,” indicating the machine setup

information has been corrupted;

3. “DC Under Voltage,” indicating that the average

rectified voltage was under 20VDC for more than

30 seconds;

30 seconds;

5. “System Scale Factor,” indicating one of the

credit peripherals has introduced an incompatible

service mode using the <clear> button.

•

Selection Switch

By pressing <enter> at the “Selection Switch” prompt,
the controller will display “Selection Switch XX,”

where “XX” indicates the first selection switch that

seconds. If there is a selection key error, navigation of
the service menu will not be possible. This error can
only be cleared by manually correcting or replacing
the keypad.
