Grounding
In order to avoid any problems with electrical noise that could negatively affect system
function, make sure that:
1. The AC power cable coming into the PWR box is always provided with a Ground
and connected to the proper connector (Protective Earth - PE).
2. The structure where the readers, controllers, encoders/tachometers, and photo-
electric sensors are mounted is grounded to the conveyor or to the PE terminal
inside the PWR.
3. The Shield wires from the Encoder/Tachometer and photoelectric sensor cables
are connected to the proper Shield terminal in the CBX box.
4. Normally, steps 1 through 3 will guarantee proper function. In case of problems
such as transmission of strange or wrong characters, devices stop working without
any reason, or other unexpected behavior, try connecting the CBX or Controller
Earth terminal to the PE terminal inside the PWR box.
