Check out the white pages, there is one about wiring and programming pneumatics. But if you don't want to read all of that, here is what it says about programming it:

In this example, the pump is controlled by the spike relay 5 output, and the pressure switch is on robot controller digital input 1 (input – pin 1 and ground pin 3). This code is inserted in the main loop of the robot controller program.

' Test the state of the pressure switch
if rc_sw1 = 1 then pump_on ' jump if under the pressure limit

' 110 psi pressure limit has been reached
' turn pump off
pump_off:
relay5_fwd = 0
relay5_rev = 0
goto nextaction:

' turn pump on
pump_on:
relay5_fwd = 1
relay5_rev = 0

nextaction:

P.s. you may want to add a delay before the pump turns off so that the pump doesn't cycle.
