Efficient Drives in the HVAC

We have been delighted that Dr.-Ing. Mathias PAUL could follow an invitation to speak at the Techniktag of theSächsischen Kältefachschule about „Efficient Drives in the HVAC“ at dec 1st 2017. Besides of many facts on EC-Motors and EC-Drives a small time slot was granted to introduce our own products to the interested audience.

The most interesting part hereby was the universal applicability of control devices from vbk technology whether asHandheld (uniquom) or ascontrol centre (uniqunet) to control differentEC-fans from ebmpapst, Ziehl Abegg, Nicotra||Gebhardt on their differentRS485-Bus-Systems ebmBUS, Modbus, GBus …). Furthermore the own process visualisation platformuniquvis was presented in a current project for KälteConcept.

uniquom - worldwide

From now on one of the greatest South African service providers inHVAC business programs and controls his ebmpapst EC-fans withModbus- andebmBUS-Interface by technologies out of the Vogtland.

With that the handhelds of theunqiuom series will be used at all continents worldwide.

"Power & Free" conveyor system on a SIEMENS PLC S7-1200

A „Power & Free“ conveyor system of a hand painting equipment for a big manufacturer of windows and doors is the latest highlight of vbk technology automation products. 13 stoppers that need to be free configurable, the control of a traction chain drive as well the automatic suction are made for the operation by a touch panel.

An especially designed functional module allows simple scalability for the present application as well as for upcoming projects. Currently this functional module is used to set minimum dwell time and maximum number of traverses per stopper by the customer.

The program is done on SIEMENS PLC S7-1200 via TIA-Portal V14.

FFU Service for NICOTRA Gebhardt

A well-known research institute in Munich had scheduled a filter change of their FFU's for the last week. Here, the opportunity was taken to check some communication abnormalities in the control of the FFU's by a FFU-Control-Centre type FanCopmmander200). The installation was commissioned with components from NICOTRA Gebhardt in 2005.

All involved have been delighted as it has been find out that neither the EC-FFUs nor the FanCommander200 has caused the problem but just a simple hidden cable damage in the main backbone. After renewing it, the installation is running perfectly again and that after this long run time.

Season's Greetings

a reflective and restful time and a sincere thank you for your confidence in us. We wish you a happy New Year!

Schenk Balancing Machines feed Process Data to modern ERP-System

For quite some time all balancing machines of a big fan manufacturer in Schwaben/Germany transfer there balancing data to their ERP System automatically. An automatic Windows Service will trigger the balancing data transfer depending on the type of machine. Either the balancing data will be transmitted as Schenk ASCII-data via serial C720 interface or a permanent access to the balancing data memory exists (CAB920) and the data will be extracted out of the xml-files.

In both cases a csv file is being created for the import from the ERP-System.
