Mazooma's Classic 7's set up help

Found the image for this on fleabay, so thought I'd have a go at emulating it.
But ran into a few start up problems I hope someone can help me with.
Coin mech error
And when the machine accepts coins it only takes one at a time.
But the more I fiddle with the settings the worse I get lol
Thanks in advance vectra666
