problem before proceeding.
7. If the PROG led does not ash after you press the READ key, the program track has
a stray voltage or isolation problem, and you will have to power cycle the DCS240+
after you x this program track issue.
8. Now move the two test track wires over to the RA/RB main track terminals. Make
sure the TRK STATUS led is lit, so the locomotive is energized.
9. On the DT602, for the active throttle press the Loco and the detected active AD2 or
AD4 address number from steps 4 or 5 earlier. Press the Loco key again to complete
decoder address selection.
10. Ensure that as you increase the now active throttle speed the locomotive responds in
both directions by movement on the track.
11. At this point you have proven the DCS240+ will operate properly and you can now
install this on your layout.
1.4 Layout hookup test: These steps will introduce the DCS240+ to an existing
layout.
1. Before connecting the DCS240+ RA/RB terminals to the layout, perform a
short-circuit detection test. With TRACK STATUS lit/ON, short these two termi-
nals or connected wires together. The DCS240+ should beep 4 times and turn OFF
the track for about 1 second, then briey pulse on the led to show it is attempting to
restart track power.
2. If the DCS240+ does not shut down reliably, check that the DC supply is rated for
5A if connected via the 2mm DC jack, or 8A if connected to the 8A+/- terminals.
3. If the PWR or NET leds ash quickly during this short test, this indicates that the
DC supply voltage collapses too low at the short circuit current draw, so a better DC
supply is required to properly operate.
4. If the Short circuit test is OK, you can now connect the RA/RB terminals to your
layout, and check you can now run the locomotive from section 1.3 step 10, OK on
the mainline tracks.
5. Now you can connect the layout LocoNet connection to a RJ12 port on this
CS. If the NET led remains lit red, you can connect the DT602 to a loconet jack
around the layout and check it will again operate the test locomotive OK.
6. As you operate the test locomotive the NET led will ash indication loconet control
messages are being received. If the NET led stays o, the loconet has short prob-
lem in the layout cabling.
7. You can now hook up an isolated program track and test it works as for section 1.3.
8. If your DCS240+ detects two command stations on the LocoNet at power up, it will
issue 10 long beeps and turn off all track power.
1.5 Shutting Down the System
When you are nished with your session, you can shut down the DCS240+ by turning
o power to the system, but this may fail to save some just-modied data. Some users
prefer to “dispatch” or release all addresses active in their system before shutting down.
This can prevent unexpected results when you power up the layout again. You can sim-
ply press the Loco Reset Button on the DCS240+ to clear all addresses from the com-
mand station at the end of a session.
