Event History
The CFN3 application remembers the last one hundred significant events. Events remembered
in history include:
• any command execution, except disk-based programs (which are files with the .BIN
extension).
• changes in switch detect on pumps.
• low level state changes for all transactions.
• other miscellaneous system events.
The event history is mainly useful for tracking down problems. Your service technician may
have you print out the history file if you call with a problem.
