b. The reverse loop should NOT use a common rail wiring scheme. Both rails must be
isolated from the rest of the layout for the PSX-AR to work properly.
c. If the PSX-AR breaker function activates, J1-1 and J1-2 are disconnected from ALL
J2 connections.
9. Connect the two wires from the DCC Booster to the PSX-AR J1-1 & J1-2 INPUT terminal
10. When Power is applied to the PSX-AR, the D12 LED near the J1 Input and the D7 LED
near the J2 Output should be on.
11. If the D6 LED near the J3 Programming Jumper is on solid, you may have a short between
the two wires from the J2 Output or in the track section.
12. Test the PSX-AR installation prior to running a train:
a. Observe your DCC booster is not shorted.
b. Use a suitable metal object to short the track.
c. The status LED D6 should come on and D7 near the output should be off.
d. Your booster should not trip during this test [D12 stays on].
13. If your booster does trip during this test [D12 goes off or flashes on and off], it may not be
able to support automatic reset.
a. Install the Manual Reset jumper [J7-1 to J7-2] and repeat the test. Your booster should
now remain on [D12 stays lit].
b. With the Manual Reset jumper in place, you can reset the PSX-AR by sending an
accessory ON command [check your system manual for correct key sequence] to
accessory address 2042 [997 if you installed the Digitrax Jumper]
c. With the Manual Rest jumper in place, you can also reset the PSX-AR by
connecting a Normally Closed momentary push button in series with the Manual
Reset jumper. Pressing the button will reset the PSX-AR.
C. How to Determine Power Districts
There are two types of power districts: Single power district per booster or multiple power
districts on a single booster. In either case, you want a PSX or PSX-AR protecting each power
district. If you have a single booster for a power district, you still want a PSX-1 protecting that
district. The reason is that the protective circuitry in the booster is designed to protect the
