This transfer switch has a built in relay. This switch is designed for 120 V loads. Relay chattering is primarily caused by insufficient voltage from the generator. Check the voltages coming in from the generator. If the voltage starts to drop below 90VAC, the relays may begin to chatter. Also check for debris in the enclosure. Below is a link to a manual that may help answer some questions.
