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 arrangement 10 is preferably manifolded (not shown), to facilitate maintenance on any detected failure, and to simplify installation and replacement.
