Not sure which Airwallet unit you have? See Which Airwallet unit do you have?.

This type of machine is installed with a single pulse-operated terminal, which is occupied by the coin acceptor. If you want the coin acceptor to stay installed, you can use a 2-POL relay (provided by Airwallet) to make a circuit in parallel. The parallel circuit goes through the 2-POL relay and the relay is controlled by the Airwallet Pro. This is illustrated by the schematic (below).
