Note
Incorrect temperature measured values as a result of cables with an excessively high
resistance
An excessively long cable length or an excessively small cable cross
-section can falsify the
temperature measurement (for a PT100, 10
Ω cable resistance can falsify the measurement
result by 10%). As a consequence, excessively high measured values are outp
ut, which
could lead to the motor being unnecessarily tripped prematurely.
•
Use only cable lengths ≤ 300 m.
•
For cable lengths >100 m, use cables with a cross-section of ≥1 mm
