RING ENGINEERING Model Railroad Auto Reverse Module AR 1 User Manual Ring Engineering Inc 219 322 0279 www RingEngineering com Revision 1 00 Copyright 2012 Ring Engineering Inc All rights reserved BEING RailPro Introduction Thank you for purchasing this Ring Engineering product We take pride in the products that we produce and hope you find this product to be a great addition to your model railroad layout Please read all warnings and instructions before installation and use For the latest information including the latest revision of this manual please visit our Internet site at www RingEngineering com The AR 1 is used to power special configurations of track such as in figure 1 These configurations of track would cause a short circuit if connected without the use of an AR 1 Note that in each configuration if you follow Rail A around you will notice that it connects to Rail B That is just like putting a piece of metal across Rail A and Rail B which would cause a short circuit and in turn would cause a power supply to shut down The solution to power special track configurations like below is to add insulation gaps and power the sections with an AR 1 The AR 1 can also be used to isolate small sections of track limiting the impact of short circuits if derailments occur to just one area of your layout uie Reversing Loop rara Reversing Y Turn Table Rail B Rail B Rail A a Rall B

5. e quarter test to every section at least every 3 feet of track until each section is tested and passes this test Since the track is exposed and can easily be shorted by things like a derailed locomotive your AR 1 has built in short circuit protection with auto recovery When a metal object gets across the track rails the AR 1 outputs are connected together and you create a short circuit The AR 1 will automatically detect the short circuit turn off the output and the power indicator light will turn red If the Output Is off all trains in the reversing section will stop because they will no longer have power The power indicator light will stay red until the short is removed After a few seconds from the short being removed the AR 1 will automatically turn the power to the track back on Your AR 1 is now ready to use Operation There is only one thing to be aware of while operating your AR 1 You should be sure that both isolation gaps are not crossed by two locomotives at the same time In a locomotive usually the wheels are wired together inside so when a locomotive is across the gap one set of wheels are contacting the track on one side of the gap and the other set of wheels are contacting the track on the other side of the gap This means that when a locomotive drives over a gap the rails on both sides of the gap are connected together by the locomotive And this is ok if one gap at a time has a locomotive over it But if two loco
