Precautions For Operation - Omron E5AN-H User Manual

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 Digital Controllers into a control panel or
similar device.
2) Make sure that the Digital 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 Digital Controller. If power is turned ON for the Digital 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 Digital 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 Digital 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 E5@N-H Digital Controllers 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 E5@N-H Digital Controllers comply with installation categories ENV1 and ENV2 of Lloyd's stan-
dards. 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-H as possible. (As a guideline,
the ferrite core should be within 10 cm of the terminal block.)
