F3S-B
11
1-6-2 Series connection types
When your application requires an additional pro-
tective zone, for example, to prevent someone
from staying behind a primary detection zone, the
F3S-B may be connected in series. The system
consists of a master unit, a slave unit, and a series
connection cable, type F39-JB1B (refer to “2-3-2
Wiring diagram” and “7 Accessories (Optional)”).
The series connection allows up to 96 axes and
2.4 m of protective height in total.
Series connection types have the same character-
istics as a stand-alone types. When the detection
zone of the master unit or that of the slave unit is
interrupted, the outputs of the master unit go to the
OFF-state.
However, please note that a slave unit does not
have indicators.
Note:
Both the master unit and the slave unit need
to be ordered separately.
