Abstract

Zwischen einer Pumpe (12) und einem hydraulischen Zylinder (13) ist ein mit Kanälen versehener Steuerblock (11) angeordnet. An dem Steuerblock sind hydraulische Ventile (18,19) gehalten, die den Druckmittelfluß steuern und durch elektrische Stellsignale betätigt sind. Beim Einsatz derartiger Steuereinrichtungen in Umformmaschinen sind hohe Sicherheitsanforderungen zu erfüllen. Um die Kosten für die sicherheitstechnische Prüfung vor der Inbetriebnahme zu verringern, ist an dem Steuerblock (11) eine elektrische Schaltungsanordnung (30) gehalten, die sicherheitsrelevante Eingangssignale entsprechend einem vorgegebenen Algorithmus zu Stellsignalen verknüpft. Die elektrischen Verbindungen zwischen an dem Steuerblock gehaltenen elektrischen Bauteilen und der elektrischen Schaltungsanordnung sind werksseitig fest verdrahtet. Die elektrischen Signale von externen sicherheitsrelevanten Sensoren (43,44,45) sind der elektrischen Schaltungsanordnung über verwechselungssichere Anschlüsse (41) zugeführt. Derartige Steuereinrichtungen dienen zur Steuerung von Umformmaschinen mit hydraulischen Zylindern, insbesondere von Pressen.
