Abstract
A binary voting solenoid arrangement 10 is provided which operates in a “2 out of 3” manner to provide relatively high safety, low spurious tripping and a relatively low installation cost, while also enabling on-line testing of each solenoid individually without process interruption. Solenoid arrangements 10, 10′ and 10″ are preferably used in a three-way configuration, while solenoid 10′″ may be used in a two-way configuration.
