LIEO
/ Power First type cards are used on DKN, Carnielli and other
treadmills. Controller models are PF 901, PF 902, PF 903, PF 905 and
PF 906. Those treadmill controllers have both optical (3-pin) and
magnetic (2 pin) connectors for speed sensor.
These
boards can be replaced with matching Endex-branded models (the
leading brand for treadmill boards).
The
signal connectors on the console are identical (7 pin + 5 pin).
If
the original board is equipped with a magnetic sensor, there is
usually no need for adaptation and you can directly replace it with
the Endex controller.
In
the case that the original board has a 3-pin optical sensor, it is
also necessary to purchase a magnetic speed sensor and a magnet to be
used with the replacement card.
The
speed sensor is connected to the only 2-pin connector on the new
board.
Second step: the front roller should be analyzed.
In most cases you will find that it already has a small magnet, in
some cases even two magnets (red arrow on the magnet, blue on the
compartment prepared for the second magnet).
In
this case, it is better to keep one magnet only, because putting two
would result in a bumpy speed.
If
the magnet is missing, proceed with bonding (with a two-component
type glue) the magnet in the seat (if present) or in any other
suitable space.
Place
the magnet and the sensor so that when the ribbon turns, the magnet
moves at about 2/3 mm from the sensor without ever touching it. http://www.partsfortreadmill.com/
