■Wiring

Connection
•Make connection after turning the power off.
•Install the lead wire separately from the route for power cable or high-voltage cable.
Otherwise, malfunction may potentially result due to noise.
•Be sure to ground Terminal FG when using a switching regulator obtained on the commercial market.
If analogue output is performed connecting to a switching regulator obtained on the market, switching
noise will be superimposed and product specification can no longer be met. This can be prevented by
inserting a noise filter, such as a line noise filter and a ferrite element, between the switching regulator and
the product, or by using a series power supply instead of a switching regulator.
Attaching the connector to the lead wire
•Sensor wire is stripped as shown in the right figure.
•Do not cut the insulator.
•The core of the corresponding color shown in the following
table is put into the pin of the number stamped on the
connector for sensor connection to the back.

•It checks that the above-mentioned preparation work has been performed correctly, and A part shown in
right figure is pushed by hand and makes temporary connection.
•A part center is straightly pushed in by tools, such as pliers.
•Re-use cannot be performed once it connects the connector for sensor connection completely. When you
fail in the connection mistake of a core and a pin, or the plug of wire, please use the new connector for
sensor connection.
•When the sensor is not connected correctly "LLL" or "HHH" can be displayed.
