4.3.3.5 Connecting between 2 and 8 load cells (650 Ω) using a 6-wire
connection cable
Connections are made via cable junction box PR6130/.. using connection
cable PR6135/.. or PR6136/... .
Recommendation
– Install cable in steel pipe connected to a ground potential.
– The distance between the measuring cables and the power cables should
be at least 1m.
Load cell supply circuit
– Load resistance of load cell circuit ≥75Ω, e.g., 8 load cells of 650Ω each
– The supply voltage is fixed at U
DC
=12V and protected against short cir
cuits.
For further technical data, see ChapterGeneral technical data.
Note:
If hum interference occurs, the cable screens should only be connected
on one side.
Depending on the design of the cable junction box used, either the
jumperJ3 must be removed or the cable screens must be disconnected
from the terminal contacts highlighted in yellow.
