Installation Instructions - AZL PA1 Locomotive
1. Remove the front coupler assembly then carefully remove the locomotive’s
shell from the frame by holding the fuel tank and pulling the body shell up.
You can use toothpicks or similar to spread
the shell slightly. Note the orientation of
the shell to frame for reinstallation. Figure
1shows the shell and light board removed
from the frame. The rear coupler is not
removed.
2. Carefully unscrew and save the 4 small
Phillips mounting screws holding the factory
light board.
3. Lift the light board gently to release it from
the motor wire loop contacts. Be careful not to distort these loops as you lift
the light board from the chassis.

gold contact pads in the middle of the
decoder. Gently press down so both of
these wire loops engage into their respec-
tive holes.
6. Align the PCB end mount holes with the
threaded mount holes on the frame castings. Place two screws at diagonal
corners and check the tolerances allow the PCB to be centered with the mo-
tor loops correctly engaged.

with CV01 (AD2) [the two digit address] set to 03. Following is a brief description
of how to change the decoder address with a Digitrax DT602 series throttle. See
your throttle Manual or system information for complete programming instruc-
tions.
1. Place the loco on the programming track, not to exceed 16V.
2. On DT602 throttle press the; MENU then 1 keys to enter Quick Decoder
Setup menu.
3. Press the READ key, and all the basic decoder addressing information will be
automatically displayed, after the required CV reads are completed.
4. The factory address will show "AD2 ShortAdr= 03" Good reads indicate the
decoder is functional and you can then edit the AD2 or AD4 LongAdr address
