In addition to controlling frog power for turnouts, the Hex Frog Juicer can be used as an automatic reverser for up to three return loops, wyes and turntables. It can also be used to control opposing frogs found in crossings and is capable of simultaneously handling three different crossings.
To use the Hex Frog Juicer as an automatic reverser, two of the frog outputs must be used for each reverse section. There are two jumper pins for setting up the outputs as 3 sets of pairs with each pair kept opposite in polarity. When a short is detected on one rail in the pair, the polarity of both paired rails automatically changes.
