FleX Layout module AB400 - User Manual
For this purpose, it is sufficient to equip the tail vehicle with a resistor on one axle,
which makes contact between the two wheels (fig. 5). We recommend a resistor
value of around 5 kΩ. In this way, there is minimal current draw at both ends of the
train in any situation, and the train is protected at both ends, the locomotive motor
(M) on one side and the resistor (R) on the other (fig. 6).
For three-rail systems, it is not possible to take over the last car with an arrangement
as described in fig. 5. The last car must be equipped with a pickup shoe and some
device that draws current (tail lights, decoder, interior lighting, etc.).
3 . Troubleshooting
To solve power supply/connection issues etc., see motherboard troubleshooting.
Problem
Possible causes
The module is
switched on but does
not respond, and the
power LEDs remain
off.
If the HP100 board is powered (green LED on HP100 is on), the
module is incorrectly inserted. Check for correct insertion.
The board is in contact with metal parts.
The module is
switched on, the
power LEDs are on,
but the trains in the
corresponding
sections do not move.
Check the correct connection of the block sections, which must
be done as in figure 2.
Check that the wires make correct contact in the terminals (they
have been stripped well and the screws are tight).
Check that the track contacts are clean.
If there is a short-circuit: Make sure that you have not mixed
wires from different control panels or boosters on the same
AB400.
The module is
switched on, the
power LEDs are lit,
the trains in the
corresponding
sections move, but
the yellow LEDs
registering presence
do not light up.
Check the correct connection of the block sections, which must
be done as in figure 2.
