■ Precautions for Correct Use
Installation
1. Do not connect the End Unit directly to an HFU.
2. Connect the End Unit to the right side of a Basic Unit.
3. Connect the HFU to the left side of the Basic Units.
4. Connection is not possible to CJ1-series PLCs.
5. Use the EJ1G-@@ for gradient temperature control. When not
6. When removing the terminal block to replace a Unit, be sure that
Service Life
1. Use the product within the following temperature and humidity

3. Mount the Temperature Controller so that it is horizontally level.
4. If the measurement accuracy is low, check to see if input shift has
Precautions for Operation
1. A certain amount of time is required for the outputs to turn ON
2. It takes 30 minutes from the time the Temperature Controller is

ranges:
Temperature: − 10°C to 55°C (with no condensation or icing)
Humidity:
When the Temperature Controller is incorporated in a control
panel, make sure that the controller's ambient temperature and
not the panel's ambient temperature does not exceed 55°C.
is determined not only by the number of times the relay is
switched but also by the service life of internal electronic
components. Component service life is affected by the ambient
temperature: the higher the temperature, the shorter the service
life and the lower the temperature, the longer the service life.
Therefore, the service life can be extended by lowering the
temperature of the Temperature Controller.
mounting Temperature Controllers above each other may cause
heat to build up inside the Temperature Controllers, which will
shorten their service life. If the Temperature Controllers are
mounted above each other or side by side, use forced cooling by
fans or other means of air ventilation to cool down the
Temperature Controllers.
However, be sure not to cool only the terminals. Doing so will
result in measurement errors.
sure to use compensating wires that match the thermocouple
types.

resistance and keep the resistance of the three lead wires the
same.

There are two holes for each terminal. The
hole on the right is the operation hole and
the hole on the left is the wire hole.
Insert a flat-blade screwdriver with a width of
2.5 mm into the operation hole, insert the
wire into the wire hole, and then remove the
screwdriver. The wire will be clamped.
Use crimp terminals that are suitable for the
cross-sectional area of the wire.
