Test Set-up for uniqunet PCBs

A new test device allows the automatic test of the uniqunet PCBs before commissioning.

  • In detail, the following steps will be performed automatically, after the 24V (=) power supply is applied:
  • - Test of all created voltages at the PCB,
  • - Functionality test of all digital In- and Outputs and adjustment of the analogue inputs.
  • test device uniqunet software
  • test device uniqunet hardware

The testing device is linked to an HTML-Web-surface at a PC from where it is controlled. An Arduino Microcontroller is working on the test board and makes the data processing for the PC-software. After the tests have been successfully a PDF is created and stored automatically.

Batching Plant for Polyurethane

The latest PLC project of vbk technology is a batching plant with 2 or 3 components for Polyurethane.
Therefor a new SIEMENS S7-1200 CPU is applied with different LCD Touch panels.

  • Software 3K Anlage Grundbild
  • Software 3K Anlage Handsteuerung
  • Software 3K Anlage Kennlinie
  • Software 3K Anlage Rezeptverwaltung
  • The special features of the project are:
  • - recording of the pump duty line, that requires no additional sensor for the volume measurement
  • - choose able operation mode - either installation stops after achieved setting or endless discharge
  • - program is configurable for 2 or 3 components, therewith less maintenance efforts achieved

Lounges - uniqunet control device supports NICOTRA Gebhardt FFU

After a few years of absence the Cleanroom Lounges took place in Karlsruhe this year again. Personal highlight for me was the operation of a of an uniqunet control device driving an EC-fan of a NICOTRA Gebhardt ( former Gebhardt Ventilatoren ) FFU.

NICOTRA Gebhardt has been an OEM costumer for our control devices for years.

Efficient Drives in the HVAC

We have been delighted that Dr.-Ing. Mathias PAUL could follow an invitation to speak at the Techniktag of the Sächsischen 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 as Handheld (uniquom) or as control centre (uniqunet) to control different EC-fans from ebmpapst, Ziehl Abegg, Nicotra||Gebhardt on their different RS485-Bus-Systems ebmBUS, Modbus, GBus …). Furthermore the own process visualisation platform uniquvis was presented in a current project for KälteConcept.
