Principle of Operations
Three ports are provided on the back of the switch housing, labeled SW1, SW2, and Supply. The pneumatic pressure input is connected to the “Supply” port. Inside the housing, the supply pressure is connected to both of the switches (SW1 and SW2). When either of the switches are tripped, the pneumatic path is opened and the switch provides output to either the SW1 or SW2 port, depending on the switch tripped.
To set the switches, simply adjust the touch-set cam in the same fashion as standard Moniteur units.
