Trouble Shooting

If things don't work right from the very start there is
usually a simple reason. But, it is not always easy to
find. That's why we want to give you some information
here about possible sources of errors.

Interface Test

Once again here our advice: Check each individual component for
proper function with the aid of the ROBO Pro interface tests.

Cables and Wiring

If an electrical component does not work at all, check the cable used to
connect it to the ROBOTICS TXT Controller again. For this purpose use
the cable to connect the lens tip lamp to the battery. If the bulb lights up
the cable should be okay.
Another source of errors are incorrectly installed plugs (for example, a
green plug on a red cable).
Also check that "+" and "-" are correctly connected. For this purpose,
compare your model with the illustrations in the assembly instructions.

Loose Connection

A component, which works sometimes and doesn't work at other
times, probably has a loose connection somewhere in the wiring for the
component.
The most frequent causes for this are:
▯ Loose Plugs
When the plugs for the cables are too loose, that is wobbly in the jack
sockets, they do not provide sufficient contact. In this case you can
carefully bend the contact springs apart at the front on the affected
connectors using a screwdriver. Just a little, so the plugs are held
firmly in the jack sockets when you plug them in.
▯ Poor Contact between Cable and Plug
Also check the contact between the stripped ends of the cable in the
connector and the connector itself. It may be sufficient to tighten the
screws in the connector slightly.
