3.12. Automatic control of the drying process holzmeister M800B (DELPHI)
Every unit is equipped with:
6 pcs of probes to detect the wood moisture
2 pcs of EMC stations/ front and back / For climate controlling
It is a LCD based automatic kiln controller. The kiln dryer controller DELPHI is based on the most advanced electronic SELLERnology today available and includes all the best solutions that LOGICA H&S has developed in over ten years of experience in timber drying control systems.
The new 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 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(in addition to internal memory), to protect the controller set-up against not authorized people and 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 Logica H&S. Thanks to a number of new
solutions (among them measures with alternate voltage variable(VAV) with timber moistures, 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) aluminum case, and complete with wirings for the probes boxes inside the kiln made with shielded and Teflon insulated cables. The probes boxes are made using polycarbonate hermetic 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.
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 master PC (using the WoodWizard 2 software). In the panel version (“easy wiring”) 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 can be directly inside if, for a very tidy wiring; the link between the modules is made with a single preassembled cable. But, if you prefer, the same solution could also be used to install the power module into the switchboard and the visualization module directly in your office, far up to 1, 2km.
