Omron E5 Getting Started Manual page 7

1) It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON.
Due consideration must be given to this time when incorporating Temperature Controllers into a control
panel or similar device.
2) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the power
before starting actual control operations to ensure the correct temperature display.
3) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Temperature Controller. If power is turned ON for the Temperature Controller
before turning ON power for the load, self-tuning will not be performed properly and optimum control will
not be achieved. When starting operation after the Temperature Controller has warmed up, turn OFF the
power and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the
Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.)
4) Avoid using the Controller in places near a radio, television set, or wireless installing. The Controller may
cause radio disturbance for these devices.
The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with Lloyd's standards. When applying the
standards, the following installation and wiring requirements must be met in the application.
■ Application Conditions
1) Installation Location
The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with installation category ENV1 and
ENV2 of Lloyd's standards. Therefore, they must be installed in a location equipped with air condition-
ing. They must therefore be installed in a location equipped with air conditioning. They cannot be used
on the bridge or decks, or in a location subject to strong vibration.
2) Wiring Conditions
Install the recommended ferrite core and wrap the line around it three turns for the applicable lines
(e.g., power supply cable line and signal lines) of the models listed in the following table. (See illustra-
tions.) Install the ferrite cores as close to the terminal block of the E5@N as possible. (As a guideline,
the ferrite core should be within 10 cm of the terminal block.)
