3.3.2.2
Cable lengths
When connecting bus versions with several sensors (
), the maximum cable
length is reduced as follows depending on the number of measuring points connected:
Proceed as follows when longer cable lengths are used to connect several sensors:
1
Use larger diameter e.g. cable type with 3 or 4 pairs of wires and 2 pairs of wires for
power supply
To ensure the power supply for long cable lengths, the following key data for the
FLOWSIC200 must be observed when selecting the wire diameter:
2
Use an MCU with more powerful power supply unit
Both solutions are available from the manufacturer on request.
3.3.3
Connecting sender/receiver units and junction boxes
These components are to be interconnected as shown in p. 48, Fig. 29:
– Between the sender/receiver unit and the junction box using the cables with connector
included in the scope of delivery,
– Between junction boxes and MCU with cable provided by customer.
