Definitions

  • the sensing apparatus in its idle state may provide an open electrical circuit that can be closed (bridged) by the filter cartridge being correctly seated in the cartridge seat.
  • the sensing apparatus in its idle state may alternatively provide a short circuit that can be opened by the filter cartridge being correctly seated in the cartridge seat. Both alternatives ensure that the sensing apparatus is only operable when the filter cartridge is placed correctly in the cartridge seat.
