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
phot
oelectric 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
c
ables are connected to the proper
Shield
terminal in the CBX box.
4. Normally, steps 1 through 3 will guarante
e 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.
Check Scanner Installation
After completing the installation of your barcode scanner, confirm that the bar-
code scanners, CBX connection box and/or
SC5000 Controller have been prop-
erly installed mechanically and electrically. Use the Installation Sequence at the
beginn
ing of this chapter and your application specifications to check your
installation.
