Safety Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of the E5@C Digital Controllers. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
Page 7 Safety Precautions Safety Precautions CAUTION Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. Electric shock, fire, or malfunction may occasionally occur. Do not allow metal objects, conductors, cuttings from installation work, or moisture to enter the Digital Controller or a Setup Tool port.
Page 8 Safety Precautions CAUTION If you replace only the Main Unit of the E5DC, check the condition of the Terminal Unit. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Controller to increase, possibly resulting in fire.
Page 9 Precautions for Safe Use Precautions for Safe Use Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unex- pected events. Do not handle the Digital Controller in ways that exceed the ratings. •...
Page 10 Precautions for Safe Use • 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.
Page 11: Installation Precautions
Installation Precautions Installation Precautions Service Life Use the Digital Controller within the following temperature and humidity ranges: Temperature: −10 to 55°C (with no icing or condensation), Humidity: 25% to 85% If the Digital Controller is installed inside a control board, the ambient temperature must be kept to under 55°C, including the temperature around the Controller.
Page 12: Precautions For Operation
Precautions for Operation 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.

Page 112: Selecting Pid Control Or On/Off Control (Not Supported For Position-Proportional Models.)
4 Basic Operation Selecting PID Control or ON/OFF Control (Not Supported for Position-proportional Models.) Two control methods are supported: 2-PID control and ON/OFF control. Switching between 2-PID con- trol and ON/OFF control is executed by means of the PID ON/OFF parameter in the initial setting level. When this parameter is set to pid, 2-PID control is selected, and when set to onof, ON/OFF control, is selected.

Page 122: Determining Pid Constants (At, St, Manual Setup)4-24
4 Basic Operation Determining PID Constants (AT, ST, Manual Setup) 4-9-1 AT (Auto-tuning) • When AT is executed, the optimum PID constants for the set point at that time are set automatically. A method (called the limit cycle method) for forcibly changing the manipulated variable and finding the characteristics of the control object is employed.
Page 123 4 Basic Operation Limit Cycle MV Amplitude The Limit Cycle MV Amplitude parameter sets the MV amplitude for limit cycle operation during auto-tuning. This setting is disabled for 100% AT. 40% AT • The width of MV variation in the limit cycle can be changed in the Limit Cycle MV Amplitude parameter, but the AT execution time may be longer than for 100% AT.
Page 124: St (Self-Tuning) (Not Supported For Position-Proportional Models.)
4 Basic Operation 4-9-2 ST (Self-tuning) (Not Supported for Position-proportional Models.) ST (self-tuning) is a function that finds PID constants by using step response tuning (SRT) when Digital Controller operation begins or when the set point is changed. Once the PID constants have been calculated, ST is not executed when the next control operation is started as long as the set point remains unchanged.
Page 125: Rt (Robust Tuning) (Used For At Or St.)
4 Basic Operation In this state, the measurement point is within the ST stable range. In this state, the change width of the PV every 60 seconds is within the ST stable range or less. In the following instances, PID constants are not changed by self-tuning (ST) for the present set point.
Page 126 4 Basic Operation RT Features • Even when hunting occurs for PID constants when AT or ST is executed in normal mode, it is less likely to occur when AT or ST is executed in RT mode. Temperature Temperature Much hunting occurs. Hunting is reduced.
