lerkarte nicht komplett ausgetauscht werden. So- mit hat Blain für diese gleichzeitig die Möglichkeit eines Upgrades zu den neuen Smartfunktionen der Next-Generation-Reglerkarte geschaffen. ZUSÄTZLICHE FUNKTIONEN Bei Bedarf kann man auch mit einem Spezial- USB-Adapter über die VISU-Schnittstelle eine Verbindung zu einem PC oder Laptop herstellen und von dort die Reglerkarte bedienen. Komplizierte mechanische Bauteile wurden durch eine clevere PID-Regelung ersetzt. Bei einem Totalausfall von Druck- und/oder Tempe- ratursensor startet in der Software ein Notpro- gramm. Dieses kann auch über eine permanente Umschaltung auf der Reglerkarte den Zeitraum bis zur Reparatur überbrücken. Der Test des am Aufzug vorhandenen Rohr- bruchventile wurde durch einen zusätzlichen Programmpunkt sicherer und benutzerfreund- licher gestaltet. ⇤ blain.de Die Autoren Dr. Ferhat Celik (Entwicklung) und Frank Pausder (Qualitätssicherung) sind Mitarbeiter der Blain Hydraulics GmbH. Normally, regulated control valves require an electronic card that ensures improved travel properties, but at the same time also consumes additional resources. Therefore, selecting the correct control valve (mechanical, electronically- regulated or frequency-controlled) is decisive from an ecological perspective and should be taken into account when selecting the valve type. SMART ELECTRONIC CONTROL VALVE The new generation of electronically controlled lift valves is distinguished by improved operabi- lity and an even greater range of use. Additional functions have also been integrated, apart from the smart operation. Blain has integrated two more sensors in its new smart electronic control valve to enable the travel properties of a classic electronic controller to be further improved (Figure 1). The pressure sensor and temperature sensor have been in- cluded in one unit to save space and thereby re- sources. As a result, integrating the small, sturdy design in existing components was no problem. When designing the controller card needed (Figure 2), attention was also paid to ecological aspects and a decision made for multiple use. By using a DIP switch, the new smart control valves can not only be driven, but also via over twenty- year old electronic control valves. Therefore, the still properly functioning “old” control valves do not have to be completely re- placed if the controller card fails. Consequently, Blain has simultaneously created for the former the option of an upgrade for the new smart func- tions of the next generation control card. ADDITIONAL FUNCTIONS If necessary, a connection to a PC or laptop can be established with a special USB adapter via the VISU interface and the control card operated from there. Complicated mechanical components have been replaced by a clever PID control. An emer- gency program starts in the software in the event of a total failure of the pressure and/or tempe- rature sensor. This can also bridge the period up to repair via a permanent switch-over to the controller card. Testing the pipe rupture valves on the lift was made more secure and user-friendlier by an ad- ditional program point. ⇤ blain.de The authors Dr Ferhat Celik (Development) and Frank Pausder (Quality Assurance) are employees of Blain Hydraulics GmbH.
