CE Standard Kiln Components Delphi Control System Two EMC Test Points

Delphi control system for wood drying equipment

The user interface, based on a LCD graphic display having a very good readability, allows an easy set-up also to not skilled users, because all setting are made through self-explaining menu and the access to most advanced settings is obtained only through addicted menus, divided from the ones most commonly used. To further improve the friendly interface of DELPHI, also for this model it has been adopted the iButton® system, an useful method, based on "intelligent buttons" that can be used to save and recall drying programs (in addition to internal memory), to protect the controller set-up against not authorized people and to upgrade the controller software. Having a drying program saved into an iButton, everybody can start a drying cycle, simply by laying the button on the addicted reader. The same solution can also be used to order to your assistance centre a drying program ready to use, without need to inputting it manually into the controller, or to transfer a program from a controller to another one. Obviously there are also many standard programs (over 80) ready to use for a lot of wood essences, recallable from an addicted menu, useful for users without particular needs or for beginners. DELPHI is supplied with LG25, the new probe amplifier of LogicaH&S.

Thanks to a number of new solutions (among them measures with alternate voltage variable (VAV) with timber moisture, digital filter for mains supply noise rejection (MNR)), this device assures the maximum reliability together with the better external noise rejection. The amplifier comes in a sealed (IP65) aluminium case, and complete with wirings for the probe boxes inside the kiln made with shielded and Teflon® insulated cables. The probe boxes are made using polycarbonate hermetic cases, assuring a good protection against dust on their internal side, a problem than affects the measures of many competitive systems.DELPHI allows a very flexible management of the drying cycle, thanks to the drying phase that can be divided in up to 8 steps, with progressive transitions of the kiln climate from step to step. Every step can be defined by gradient, EMC value or duration. A so high flexibility allows Delphi to be used also for thermal treatment required by phytosanitary measures. DELPHI is based on KILN BUS system that makes it compatible with all the sensors/actuators for kiln dryers today available and to be developed in the next future, so it is suitable for future upgrades. In addition it comes with a serial interface (double standard - RS232 + RS485) useful to connect it to a master PC (using the WoodWizard 2 software). DELPHI controller is supplied split in two very small parts: the visualization module and the power module. With this solution the visualization module can be installed on the front panel of the switchboard while the power module can be installed directly inside it, for a very tidy wiring; the link between the modules is made with a single pre assembled cable.
