Connector Connection - SMC Networks PF3W3 Series Operation Manual

Connector connection

Connections should only be made with the power supply turned off.
Use separate routes for the Flow monitor wiring and any power or high voltage wiring. Otherwise,
malfunction may result due to noise.
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply. When a switch-mode power supply is connected to the product, switching noise will be
superimposed and the product specification can no longer be met. This can be prevented by inserting a
noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and the
product, or by using a series power supply instead of a switch-mode power supply.
Connection of the sensor lead wire and connector
•Strip the sensor lead wire as shown in the figure on the right.
(Refer to the following table for the connector and applicable wire size)

ZS-28-CA-4 (option)
ZS-28-C-1
∗: The standard value of the insulation outside diameter of AWG No.23 is φ1.14, but ZS-28-CA-4 is recommended as an applicable
connector, taking outside diameter error into consideration.
•Do not cut the insulator.
•The core of the corresponding colour shown in the table below is put into the pin of the number stamped
on the connector for sensor connection to the back.

∗: When using the lead wire with M8 connector included with the PF3W5 series.
•It checks that the above-mentioned preparation work has been performed correctly, and "A" part shown in
the left figure is pushed by hand and makes temporary connection.
•"A" part's center is straightly pushed in by tools, such as pliers.
•Connector for sensor connection is cannot be reused once crimped for connection.
•For the connection failure such as incorrect order of wire and incomplete insertion, please use the new
connector for sensor connection.
•When the sensor is not connected correctly, "LLL" can be displayed.
