Bonjour les sloteurs,
Je viens de recevoir un message de Polistil concernant mon problème, voir mon premier post.
Effectivement le courant est coupé par les contrôleurs lors d'un échauffement de ces derniers.
En résumé lorsqu'on pose la question à un revendeur de matos si les voitures sont compatibles avec les anciens circuits Polistil des années 70.
Il faut répondre oui mais...
thank you for your email and for choosing our track system!
Yes you are right. You will hear a first 'click' when the controller reaches its thermal limit, and a second click after about one minute when it return back to normal temperature.
There are three protection systems in our track
1 - the transformer is protected again a direct short circuit.
2 - the power base limits the sustained current to about 0.7A per lane. In other words, if the current goes above 0.7A for a prolonged period of time, the protection activates and cuts power as long as the current is above the threshold.
3 - the controller is temperature protected. It works like this: if you keep the controller at about mid way for an extended period of time, the resistance inside the controller can become very hot. This may lead to smoke coming out of the controller, and in extreme cases, to controller damage. To avoid this, we have inserted a temperature switch, that cuts power above if the resistor reaches about 55°-60°C (the outside will not get this hot). When the temperature return to normal, the safety switch resets automatically.
