Pneumatics Control Module
The PCM is used to control the compressor, solenoids, and pressure switch. The pressure switch should be wired into the 2 ports labeled “PRESSURE SW”, while the compressor’s red and black wires should go directly into the red and black “COMPRESSOR OUT” Weidmuller connectors.
It will put out approximately 120psi before the relief valve opens. Because the compressor can produce a significant amount of vibration, we recommend that you use vibration isolation mounts that come preinstalled on the compressor. The compressor should be wired directly to the “COMPRESSOR OUT” Weidmuller connectors on the pneumatic control module (PCM). Do not reverse the compressor!
Pressure Relief Valve
Formerly known as Norgren has supplied the 120 PSI pressure relief valve the pressure relief valve needs to be connected to compressor via hard fittings. This is a safety measure meant to ensure proper operation of the pneumatic system.
The switches will open at approximately 115 psi and will not close again until the pressure drops to approximately 95 psi. This will allow you to turn off the compressor once you are up to 115psi, saving power in the battery. It must be wired directly to the “PRESSURE SW” Weidmuller connectors.If any Solenoid Valve object is opened (LabVIEW) or constructed (C++/Java) in your code, the PCM compressor control will be automatically enabled.
The tank is designed to withstand up to 125 psi and temperatures from 35F to 100F. It should also be installed such that it is protected from impact to reduce the risk of rupturing. When securing the tank ensure that fasteners do not get over tightened or apply pressure to the tank.
This is a relieving regulator. This means that it will limit the downstream system pressure and can relieve excess pressure if something in the downstream system causes the pressure to increase. This regulator has a maximum output pressure of 60 psi and must be placed before any working components.
The pictures above show what you will receive and how it should look when assembled. The pneumatic tube fittings are the “push to connect” type so all you have to do is push in the tubing and then pull back slightly to ensure a snug fit.
These gauges should be installed in the system to show stored and working pressure, meaning that two are usually required. The gauges read from 0-160 psi, 0-11 bar, and 0-1.1 MPa.
This valve can be used to release all of the air in the system. This valve must be installed in a location that will release all system pressure when opened. The valve should be placed in an easy-to-get-to location on the robot.
The tubing has an outside diameter of 0.25″ and an inside diameter of 0.160″. The tubing provided in the rookie Kickoff Kits is black while FIRST Choice has an assortment of colors. Be careful when cutting tubing as angled cuts can result in leaks.
Custom Bimba Cylinders
The custom cylinder has this flexibility will significantly increase your ability to design pneumatics into robot. Most of the bore and stroke options are in stock and Bimba is ready to ship directly to your team. All the actuators can be ordered with a magnetic piston and two magnetically operated reed switches.
