Also using the 48volt line power to operate the relay.Only thing I did to insure operation was a plug a small blade flat screw driver in the center of the spring that aided the reset of the relay. Just a simple small twist to open the coil a little, and it worked like a charm. My out of pocket expense was a buck for the board fifty cents for the transistors used in the timer circuit. The other parts I got from scrap electronics including two dip relays. But I hadn't tried a timer chip as Stan did. But basically the same circuit. But I didn't have to modify the relay at all, every thing was the same original as installed. The circuit was just slightly larger to have room for the dip relays. It all fit right in the top next to the coin relay. Even with the upper removed, it was hardly noticeable.
