Abstract

Die vorliegende Erfindung beschreibt eine Sicherheitsfernsteuerung für den Betrieb von Hochdruckreinigern. Sie ist dadurch gekennzeichnet, dass der Motor der HD-Pumpe durch eine Sicherheitsschaltung Ein- und Ausgeschaltet wird, wobei die Sicherheitsschaltung selbst durch ein Signal eingeschaltet wird, welches direkt von der Sprühlanze aus ausgelöst wird, und durch ein Signal ausgeschaltet wird, welches durch eine Drucküberwachung mittels eines Abschaltkontaktes abgeschaltet wird, sobald kein Hochdruck entnommen wird.

The present invention describes a safety remote control for the operation of high-pressure cleaners. It is characterized in that the motor of the HD pump is switched on and off by a safety circuit, the safety circuit itself being switched on by a signal which is triggered directly from the spray lance and by a signal which is switched off by a Pressure monitoring is switched off by means of a switch-off contact as soon as no high pressure is removed.
