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 PR6130/.. using connection
cable PR6135/.. or PR6136/... .
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 1m.
Load cell supply circuit
– Load resistance of load cell circuit ≥75Ω, e.g., 8 load cells of 650Ω each
– The supply voltage is fixed at U
DC
=12V and protected against short cir
cuits.
For further technical data, see ChapterGeneral 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
jumperJ3 must be removed or the cable screens must be disconnected
from the terminal contacts highlighted in yellow.
