A new dimension in safety and security: The D+H control panel CPS-M is a communications expert
11,500 development hours—since mid-September of last year more than 14 D+H developers worked day in and day out on the new digital smoke vent control panel CPS-M. Maik Schmees, Technical Manager and Officer of D+H Mechatronic AG, talks about the largest develop-ment project in the history of the company. It was presented for the first time at the FENSTERBAU FRONTALE trade fair in Nuremberg. The CPS-M is more stable, more compact and, thanks to the new Advanced Communication Bus (ACB) function, substantially more intelligent than its predecessor.
Smart, smarter, CPS-M
D+H revolutionises the control panel technology with the ACB function. Now the control panels no longer just communicate with the drives in one direction and, thanks to the AdComNet, provide for opening and closing windows in complex scenarios, but they also give feedback to the user. "No control panel has ever been as communicative as the CPS-M", says Maik Schmees. "We are talking about bidirectional communication." What position are the windows in at the moment? Are they locked or not? Are all connections functioning? What is the software version of the motor and how often has it already opened and closed? Diagnostics and configuration as well as improved activation with perfect positioning and formation of virtual groups at a single output all take place directly at the control panel.
The CPS-M has a capacitive TFT display, 3.5 inches large and in full colour, which allows for a better overview and self-monitoring of all functions. Stefan Decknatel, Department Manager of Innovation Management at D+H Mechatronic AG points out that "everything becomes easier for the customer with the CPS-M." For example, the
new display would also make it possible for an authorised building superintendent to configure settings. "That used to require a special
visit from the D+H partner." In addition to the display and the internal communication, the entire design has been revamped. Previously the modules in the control panel had to be 70 mm wide for an output current of 20 A, today they only need 26 mm. The higher packing density enables more functions within the same installation space. This means the model is installed in a smaller housing—an additional advantage.
Suitable—for any drive
The output current is available in 10, 20 or 40 A. This means that the CPS-M optimally adapts its current pitch to the current consumption of the D+H drives. But not only to these. "During development, it was important to us that, in the end, we would have a control panel to which all of the drives could be connected," says Schmees. For this purpose, a stabilised power supply unit with low ripple was developed. There are significantly fewer voltage fluctuations, which means the ripple at 24 V is only 0.5 Vpp. Customers have a substantial advantage if they use the D+H drives in combination with the new CPS-M. That is the only way the ACB function explained above comes into use. Decknatel explains that "perfect communication works only with D+H products and our ACB function, which is why we speak of the D+H solution."
As of now, power supply operates on the plug-and-play principle. This means that the modules need only be plugged together. The result is a better power supply. Fewer wires, lower effort for the customer during installation. Another great advantage of CPS-M is that essential functions, such as the pulse module for activation by a central fire alarm or actuator modules, are already incorporated and can be integrated quite easily with the software (SCS) at the click of a button. For example, if you would like to configure an activation module for sun shades or a fire detector module, then you can do this quite easily by using your laptop and the SCS software. If a change of use is necessary, it is possible to adjust the assignments of lines and groups in the object via simple reprogramming. This saves a lot of time and reduces wiring effort. Software updates for drives are also easy to install thanks to the ACB function.
D+H goes digital
Digitalisation is becoming ever more important also for safety and security technology. The CPS-M can be integrated into the existing infrastructure of building automation via the Ethernet and thus, for example, interact with the heating, ventilation, intrusion or fire alarm systems. In addition, it features an electric fuse. Every short-circuit is detected, the system automatically switches off and after the error is remedied it switches back on. The advantages: it is no longer necessary to replace fuses; the customer has more convenience, less time investment and lower costs. An event buffer logs the errors. This makes it extremely easy to search for and eliminate defects. The control panel is planned to be available on the market at the end of summer in 2016.
