The problem is that frog juicers are too slow. The PSX will detect the short before the juicers operate. The best solution is to avoid Juicers and simply power route the frog so that it is properly powered. This will avoid any short circuits. If that does not appeal to you, the next best thing is to slow down the PSX. You can do this by setting CV55=1. If this does not solve the problem, you can set CV65= 32, 40, or 48 to lengthen the trip time. This is a new feature, so to verify that your PSX has it, place the program jumper to program and turn on power. Observe D6. When you turn on power, you should see four short flashes. Any other flash pattern is the wrong software version. If your version is not the latest, we can upgrade it for you.
