3.8.6. Wire the Switch in Series Using the Quick Disconnect
Use models
SI-RFS
and
SI-RFD
for this configuration.

ONTEXT
:
When connecting units in series, simplify the wiring using special t-adapters and low-cost unshielded four-wire double-ended cables. A similar
configuration is shown except the connections are all made using quick disconnects. The
SSA-EB1PLx-0Dx
E-stops,
SI-RFD
switches, and the
SSA-ISD Connect can be combined in a single chain.
1.
Connect the female 4-pin M12 cable to the male 4-pin M12 of the series connection t-adapter (
SI-RFA-TS
).
2.
If a manual reset model sensor is used, connect the female 8-pin M12 of the Reset T-Adapter (
SI-RFA-TK
) to the male 8-pin M12
connector of the series connection t-adapter. Connect a female 4-pin M12 cable to the male 4-pin M12 QD of the t-adapter for
connecting a reset switch or reading the Auxiliary output.
3.
Connect the sensor to the male 8-pin M12 connector of the t-adapter.
4.
Connect the male 4-pin M12 end of a double-ended cable to the female 4-pin M12 of the t-adapter. Connect the female 4-pin M12 end
of the double-ended cable to the next series connection t-adapter (
SI-RFA-TS
).
5.
At the end of the line a terminating plug (
SI-RFA-P
) is required to properly truncate the system.
6.
The wired end of the 4-pin M12 cable (from step 1) can be wired directly to a Safety Monitoring Module or can be wired through an
In-Series Diagnostic (ISD) module then to the Safety Monitoring device.

ASK
:
Verify that the SI-RF Safety Switch and the safety monitoring module are powered from the same power supply or the commons of the separate
supplies are the same. Ensure that the voltage level at SI-RF 1 (furthest from the power supply) is above 19.5 V for the system to operate prop
-
erly.
Figure 7:
Wiring the switch in series using the quick disconnect connector
In long chains, or chains with a lot of ISD devices, the voltage at the first device (device closest to terminating plug) must stay above 19.5 V for
the chain to operate properly.
For guidance on the maximum total cable length and a maximum number of devices before an additional power supply may be needed, refer to
Maximum total cable length for a single power supply
. For using ISD information to monitor the individual device voltages, see
.
An additional power supply may be required to maintain a minimum of 19.5 V at all devices. There are two options to connect an additional power
supply.
