Warning

Please ensure that you have established common ground between logic and coil power before turning on high voltage on your coils (especially on homebrew machines). Ignoring this might lock on your coils, overheat them, burn down your house or kill you. We are serious, floating grounds are dangerous. If you are not an electrical engineer read the guide about voltages and power.

In a nutshell: You need to connect your logic ground (5V/12V) and your high voltage ground (48V or 80V). A power entry or power filter board is a convenient solution to solve this (and more) issues.

Always turn all PSUs off when connecting power or you might fry all boards at once. This is generally a good idea but even more important when connecting more than one power supply to a board.

IF YOU DID NOT UNDERSTAND WHAT THIS WARNING MEANS STOP NOW AND TRY TO UNDERSTAND IT. OTHERWISE YOUR HARDWARE WILL LIKELY BURST INTO FLAMES AND YOU NEED TO WAIT A FEW DAYS FOR A REPLACEMENT OR EVEN WORSE IT MIGHT KILL YOU. IGNORING THIS IS THE MOST COMMON CAUSE FOR BROKEN DRIVER BOARDS.

Configure drivers according to the manual of your machine. LISY does not support any hold_power or pulse_power other than 1.0. So the coil will always enable with full power (which is fine in older machines and should not break things). However, you can still choose the pulse length using pulse_ms.

coils:
  c_some_coil:
    number: 04
    default_pulse_ms: 10
    allow_enable: true

In some Gottlieb machines coils were connected to the lights bank. To address those you have to add 100 to their number from the manual. For instance, to address a coil which is connected to the light output 05 use coil 105:

coils:
  c_coil_on_light_bank:
    number: 107
    default_pulse_ms: 10
