Precautions for Operation
E5@C Digital Temperature Controllers User’s Manual (H174)
Precautions for Operation
• When using 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.)
• Avoid using the Digital Controller in places near a radio, television set, or wireless installing. The
Digital Controller may cause radio disturbance for these devices.
