Inductive components
Installing the QC-PDS system requires certain precautions regarding the
connection of the inductive components, such as contactors, relays,
electrovalves, motor brakes and, in general, any type of windings.
Thus:
All inductive circuits or components must have their own interference
suppressor that must be installed as close as possible to the inductive
component.
The mentioned interference suppressors will be RC circuits, varystors
or suppressor diodes.
The excitation cables of the inductive components and the signal cables
must not run in the same channel especially when not using shielded
cables for these signals. A typical scenario is when using inductive
proximity switches or similar usually connected with an unshielded ca-
ble.
In extreme situations, and if the sensors on the machine are very sen-
sitive to interference being carried along the 24 V DC power cables, it
may be necessary to isolate or decouple their power supply from that
of the power supply of the other system elements (inductive compo-
nents, drives, etc.).
MANDATORY.
Do not use fly diodes as interference suppression
elements for inductive components. These diodes can only serve as
interference suppressor of the inductance due to the cabling itself.
