【発明の名称】ホツトメルト加熱装置におけるヒ-タ・回路及び温度センサの性能低下の検出及びチヤンネル結線の検査方法
Document Type and Number:
Japanese Patent JP2530831
Kind Code:
B2
Abstract:
A method of checking to determine a) whether the heating elements and temperature sensors of the various components of a hot melt heating and dispensing system, such as, hot melt dispensers, hoses, and associated reservoir and manifold, are connected in proper circuit configuration, b) whether any of the heating circuits are in an open- circuit condition and/or their respectively associated signal-controlled switches which control energization of the heaters thereof are short circuited, and c) whether any of the temperature sensors are open-circuited. The checking is performed by a microprocessor having multiple channels to different ones of which are connected the sensors and signal-controlled switches of the different system components.
