Abstract
An out-of-product alarm process includes initiating an out-of-product check by sending a signal to a controller from an optical sensor assembly connected to a fluid delivery medium for delivering a product to a fluid dispensing site, performing an out-of-product check, running an alarm cycle with the controller after receipt of an out-of-product signal, and executing a corrective action. Performing the out-of-product check includes directing light into the fluid delivery medium, generating a detector output based on detected light within the fluid delivery medium, determining an out-of-product state within the fluid delivery medium based on a comparison of the detector output to an out-of-product threshold, starting an out-of-product timer, when the out-of-product state is determined, and determining an out-of-product event when the out-of-product timer reaches a threshold out-of-product time period.
