Interlock function
External device monitor function Valid
Auxiliary output
The device output is selected depending on the connecting state of the output polarity setting wire
(shield).
Incorrect wiring may cause the lockout state.

2-5-8 Series and Parallel Mixed Connection

(Wiring Example of the Control Category 4)
This is the configuration for connecting multiple sets of emitter and receiver facing each other in
mixed series and parallel combination. It is used when there are two or more dangerous parts
that can be entered from two or more directions. Up to three sets of the devices in total of the
series connection and parallel connection can be connected in combination. However, the total
number of beam channels available is 192. In case of series connection, if any of the sets is in
light blocked status, the control output (OSSD 1 / 2) turns OFF. In case of parallel connection,
for the control output (OSSD 1 / 2), only the set of which light is blocked turns OFF.

Can be used
● For series connection, connect the emitter and emitter, receiver and receiver
respectively using the exclusive cable (SFB-CSL□) for series connection as
shown in the figure on the next page. Wrong connection could generate the
non-sensing area, resulting in death or serious injury.
● For parallel connection, connect the one receiver to the other connection using
the interference prevention line as shown in the figure on the next page. Wrong
connection could generate the non-sensing area, resulting in death or serious
injury
