Beverage cooler with plug for fault analyser

摘要

In a beverage cooler, all of the leads to the electrically-operated components of the cooler are brought to a common plug 9 with the leads having a gap which is normally bridged by an external mating (dummy) plug 16, and removal of the plug 16 disconnects the components so that an automatic analyser can be connected in line to form a temporary bridge to reconnect the components in sequence so as to permit the analysis of the electrical characteristics of the components. Detection of a fault is indicated by illuminating a corresponding LED and the test sequence is stopped. IMAGE
