Series Connection - Panasonic SF4B-F31G(V2) Instruction Manual

2-5-6 Series Connection

(Wiring Example of the Control Category 4)
[Connectable up to 3 sets of the devices (however, 192 beam channels max.)]
This is the configuration for connecting multiple sets of emitters and receivers facing each other
in series. It is used when the dangerous part can be entered from two or more directions. If any
of the sets is in light blocked status, the control output (OSSD 1 / 2) turns OFF.

The device output is selected depending on the connecting state of the output polarity setting wire
(shield). Incorrect wiring may cause the lockout state.

Vs to Vs - 2.5V (sink current 5mA or less): Emission halt (Note 1), Open: Emission
K1, K2: External device (Forced guided relay or magnetic contactor)
Notes: 1) Vs is the applying supply voltage.
2) The circuit diagram shown above is for 12-core cable to be used. For 8-core cable, red, yellow, gray, gray /
black, sky-blue / white, sky-blue / black, there is no lead wire.
3) For resetting, refer to "3-2 Interlock Function."

For series connection, connect the emitter and emitter, receiver and receiver re-
spectively using the exclusive cable (SFB-CSL□) for series connection. Wrong
connection could generate the non-sensing area, resulting in death or serious in-
jury.
