STANDALONE MODE ERROR HANDLING
When operating the pump/dispenser in standalone mode (not connected to a fuel management system), the
9800Q displays two-digit error transaction codes on the LCD displays when transactions are terminated
abnormally (by a means other than turning off the pump handle).
There are four possible error conditions that may be displayed:
Code Condition
55 Power
failure
56 Pulser error
57 Timed out
58 Limit cutoff
The error codes are displayed for two seconds at the left of the LCD window, alternating with a five second
display of the last sale amount. The display alternates between the two until a new transaction begins.
When an error occurs, the user should note the error code and relay the information to the system
administrator.
Transaction error codes are displayed only when the pump/dispenser is operating in standalone mode.
When connected to a fuel management system, (on-line mode), transaction error codes are transmitted
back to the fuel management system with the completed transaction data.
