I have a Hamilton interface GL-ACW card system interface kit Part # 100-0064 installed on a Gold Line cashier. My question is about the green 7 screw terminal strip. I believe terminals 2, 3, 4, and 5 send 24V to the plc when the customer presses one of the wash buttons. I'm not sure about terminals 1, 6 and 7. The Hamilton instruction sheet does not make it clear. Would someone famaliar with this interface and understands the purpose of these three terminals please share that information with me. Thanks for your help.
