5.3 Schematic Structure
In the diagram below is a schematic representation of module interconnections in an example with ISA T4.
The Sensor module should be mounted close to the place of measurement. The maximum distance between
Sensor module and Sensor head is determined by the length of fibre optic cable (depending on version up to
10 m). The Sensor module and the BlueBox are in version ISA T4 connected by CAN-bus cable (type of cable:
LiYCY 2x2x0.5 mm² with an impedance of approx. 100 Ω). Cable lengths up to 200 m are possible
∗
, so that the
BlueBox as central control unit of the measuring system can be mounted in a control station.
A PC (or Notebook) with BlueBox system-software installed is necessary for the configuration of the system.
For direct connection with a PC/Notebook use a standard or crosslink network-cable.
6 Commissioning
The commissioning of the ISA spectrometer is described in detail in the attached
Manual ISA and Process Spectrometer Commissioning - Maintenance - Service
.
