Installation
1)
Connect the DeviceNet Communications Unit to the left side of a Basic Unit or an End Unit.
2)
The EJ1 cannot be used linked to a CJ-series PLC.
●
Service Life
1)
Use the product within the following temperature and humidity ranges.
Temperature:
−
10 to 55
°
C (with no icing or condensation)
Humidity: 25% to 85%
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.
2)
The service life of electronic devices like the Temperature Controller is determined 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.
3)
Mounting two or more Temperature Controllers side by side, or 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.

Precautions for Operation
1)
It takes a certain amount of time for the outputs to turn ON from after the power supply is turned ON. Due
consideration must be given to this time when designing control panels, etc.
2)
It takes 30 minutes from the time the product is turned ON until the correct temperature is indicated.
Always turn ON the power supply at least 30 minutes before starting temperature control.
3)
Avoid using the Temperature Controller near a radio, television set, or other wireless device. Its use would
result in reception disturbance.
