Cable routing
Fig. 16: Cable routing
Route the signal cable separately
The signal cable must be routed separately from potential sources of interference, such as motor supply
cables, 230 V power cables etc.!
AC
Interference caused by cables routed in parallel can influence the signal form of the test pulses and thus
cause diagnostic messages (e.g. sensor errors or OpenLoad errors).
D: Distance between the cable ducts should be as large as possible
blue arrows: signal line
red arrows: potential source of interference
The common routing of signals together with other clocked signals in a common cable also reduces the
maximum propagation, since crosstalk of the signals can occur over long cable lengths and cause diagnostic
messages.
