Cable quality monitoring CF.Q

Option 1 - sacrificial cable
In this option, space is still needed to route an additional cable in the e-chain® because the CF.Q is routed as a "sacrificial cable" in the e-chain®. All cores of the cable are "connected in series" and connected to the measuring input of the module

• Advantage: All cores are measured, which means that there is no need to select the most frequently used cores.
• Disadvantage: Regardless of the production batch and the assembly method, even cables from the same production batch can achieve different service life durations.

Option 2 - unused cores of a cable
In a monitored cable, two unused cores are defined as measuring cores and, if necessary, routed to the measuring connections of the CF.Q A module by means of a shielded extension cable. This often requires a modification of the connector assembly, as the two cores must be led out of the connector on the distributor side at the cable entry.

• Advantage: The cable actually used by the customer is monitored
• Disadvantage: The original cable often has to be replaced by a variant with two additional cores, which usually increases the cable diameter, and the apparently "weakest" cores should be chosen.
