An electronic control circuit, for use in connection a hot melt adhesive dispensing system, comprises a pair of redundant heater elements which are disposed together in a first, single heater element cartridge body disposed within a first cavity defined within an applicator head, and a pair of redundant temperature sensors which are disposed together within a second, single temperature sensor cartridge body disposed within a second cavity defined within the applicator head. The disposition of both redundant heater elements within the first, single heater element cartridge body, and the disposition of both redundant temperature sensors within the second, single temperature sensor cartridge body permits the applicator head to be reduced in size and rendered more compact, and the electrical connection of the redundant heater elements and the redundant temperature sensors to the power circuit more simplified. |
