1. Test the PSXX 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 D17 should come on and D7 near the output should be off.
d. Your booster should not trip during this test [D12 stays on].
2. 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 PSXX by sending an
accessory ON command [check your system manual for correct key sequence] to
accessory address 2042. Refer to CV68 for address limitations.
c. With the Manual Reset jumper in place, you can also reset the PSXX by connecting
a Normally Closed push button in series with the Manual Reset jumper. Pressing
the button will reset the PSXX.
C. How to Determine Power Districts
If you are using both PSXX circuit breakers and PSX-AR auto reversers on a layout make
sure the PSX-AR J1 input is taking power from the J2 DCC track output of the PSXX
When PSXX are used with PSX-AR, the PSX-AR trip rate must be equal to or less than the
trip rate of the PSXX. If PSXX trip rate = 2amps, then PSX-AR trip rate must be =/less than
2amps. Reference your PSX-AR manual for setting trip rate.
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 PSXX protecting each power
