Series Connection - Panasonic SF2B Series Instruction Manual

2-5-4 Series Connection

SF2B-H□: Connectable up to 3 sets of the devices (128 beam channels max.).
SF2B-A□: Connectable up to 3 sets of the devices (64 beam channels max., however, when
2 sets are connected, 96 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.
When SF2B-H□ and SF2B-A□ are combined in series connection, double the
number of the beam channels of SF2B-A□ to calculate the total number of beam
channels, which should be 128 or less.
<e.g.> The total number of beam channels for SF2B-H36 and SF2B-A44SL is
For series connection, the sub sensor exclusive for series connection (SF2B-□SL) and the
cable for series connection (SF2B-CSL□) are required separately.
Connect the emitter of the main sensor (this device) and the emitter of the sub
sensor exclusive for series connection (SF2B-□SL), the receiver of the main sen-
sor (this device) and the receiver of the sub sensor exclusive for series connec-
tion (SF2B-□SL) respectively using the cable for series connection (SF2B-CSL□).
Wrong connection could generate the non-sensing area, resulting in death or seri-
ous injury.
Emitter
<Reference>
The wiring method depends on the type of bottom cap cable. Refer to "2-5-2 I/O Circuit and Con-
nection" for the details of wiring.
When using the bottom cap cable (SF2B-CB05-B) (optional),
make sure that the frequency selector at the insertion slot of
bottom cap cable on this device is set to "1" position (on both
emitter and receiver). If they are in the position other than the
above, the device may not operate properly.

124.
The number of beam channels of SF2B-H36 + (the number of beam
channels of SF2B-A44SL x 2) = Total number of beam channels
36 beam channels + (44 beam channels x 2) = 124 beam channels
