Appendix L: Error Codes
The severity level of errors are set in Programming Function F39. Error codes are displayed in
Statistical Functions S21 and S22. Depending on how function programming is set, the error may be
logged and the dispenser may continue operation, the error may be logged and that sale is
terminated or that side of the dispenser is shut down, or both sides are shut down. When the side (or
both) are shut down, the dispenser must be reset by cycling power or the fault condition must be
corrected. Computer error codes are displayed sub-functions
S21.XX for Side A and S22.XX for Side
2, where
XX is between 01 and 50 and represents the error/events records maintained by the
computer program - with 01 being the most recent. The computer can store up to 50 errors per side,
continuing to store errors beyond the 50
th
by cycling the error buffer with new errors inserted at the
top of the buffer. When this happens, an error is deleted at the bottom of the buffer for every new
error that is inserted in the top of the buffer.
Errors are displayed in an alternating 2-page format. Information in the error pages is given below.
For units without Price displays, all of the information is sequenced through the “Volume” display.
