Datalogic SG4 FIELDBUS Series, Instruction Manual, Page: 84 / 136

FUNCTIONS
74 SG4 EXTENDED
The connection among the light curtains needs a Cascade Cable that is available in three
different lengths:
• Cascade Cable 1 m (CS-F1-80-B-01)
• Cascade Cable 0.5 m (CS-F1-80-B-005)
• Cascade Cable 0.05 m (CS-F1-80-B-0005)
The cascade cable must be connected between a Top side (without LEDs) and a Bottom
Side (with LEDs) of two SG4-P Light Curtains.
CODING (SG4-P MODELS)
The coding function allows the ESPE to remain in normal operation also when an inter-
ference condition with another ESPE occurs, and in particular when the TX of the first
light curtain radiates in the direction of the RX of the second light curtain.
Obviously, both light curtains must be configured with two different codes (see also
"
Distance between homologous devices" on page 14
).
No Code
In this situation, no code is selected and the safety light curtain has to be installed at a
certain distance from other light curtains with no code, in order to avoid possible inter-
ferences that can lead to a dangerous situation.
If the user has to install the light curtains nearer than the minimum allowed distance he
should take care to install the TX of the first light curtain on the same side of the RX of
the second.

damages.
