Helvest FleX Motherboard HP100 - User Manual
- a single “Layout” module, in
any of the available slots;
- two identical “Layout” modules
with the same function
- two different “Layout” modules
with different functions.
It is possible to install only one
"net" module, which
communicates with the digital
control unit.
The system will automatically identify the inserted modules and their position,
activating the corresponding functions.
To insert the module, place it in the desired position being careful of the right
orientation, align the connectors and exert a slight pressure (fig. 4). To remove the
module, pull it out gently.
Check that all connectors are aligned with their respective sockets before inserting
them.
Never force the board connectors as this may damage them.
2.3 Electrical connections
The HP1 board can be powered by alternating or direct current between 7 and 16V
(commonly supplied by any transformer or power supply for model railway), or by
digital signal (DCC or other).
The power supply should be protected against short circuits. Protection is normally
included in all model railway power supplies.
If you want to use it as a decoder, the easiest thing is to supply it directly through
DCC.
To connect it to the power supply, loosen the screws in terminal no. 6 of figure 2,
strip the sheaths about .5 cm long and connect the two wires of the power supply to
the terminal as shown in figure 5. The two wires can be reversed without any
variation. Then tighten the screws firmly.
If the wire is very thin, fold it up as in figure 5 on the sleeve to ensure good contact.
Do all this with the power off.
Do not connect the board to voltages higher than those indicated or to
digital signals not expressly provided for model
railway! Connecting higher voltages can cause
irreversible damage to the card, serious risks to the
user and fire hazards.
Connecting auxiliary boards or circuits other than
those supplied officially may damage the product
and invalidate the warranty.
When the board is correctly powered, the green LED (no. 8 in fig. 2) lights up.
To connect the additional modules, refer to their manuals.

3.1 The most common problems
Problem Possible causes and solutions
The board does not light up (green LED
no. 8 does not light up)
Input cables (connector no. 6) are not
properly connected.
The board touches metal parts.
There is a short circuit in the rest of the
system (the control unit or power supply
have turned off).
There is a short circuit in the outputs of
the board (check the output of the layout
modules).
If the short circuit cannot be detected,
remove the layout modules one at a time,
and try again, to find out which module
the problem is in.
The Board does not perform the
functions of the installed modules.
The plug in of the modules is wrong.
Check the correct insertion.
