How to Use the Omron E5CW-R1KJ Temperature Controller
The Omron E5CW-R1KJ is a digital temperature controller that can be used for various applications, such as heating, cooling, or alarm output. It has a thermocouple input, a relay output, and a terminal block connection. It also has a 7-segment digital display and front panel keys for easy setting and operation. In this article, we will explain how to use the Omron E5CW-R1KJ temperature controller and provide some tips and precautions.
To use the Omron E5CW-R1KJ temperature controller, you need to connect the power supply, the thermocouple, and the load to the terminal block according to the wiring diagram shown in the user's manual[^1^]. You also need to set the temperature scale range and the alarm mode using the rotary DIP switches on the side of the controller. The temperature scale range can be selected from 0 to 400 â, 0 to 999 â, or -199 to 999 â. The alarm mode can be selected from eight options, such as upper-limit alarm, lower-limit alarm, or deviation alarm. The default settings are 0 to 400 â and upper-limit alarm.
After wiring and setting the DIP switches, you can turn on the power and set the desired temperature (set point) using the front panel keys. The set point can be adjusted by pressing the UP or DOWN key. The current temperature (process value) and the set point are displayed alternately on the 7-segment display. You can also switch between them by pressing the SHIFT key. The output indicator (OUT) and the alarm indicator (ALM) show the status of the relay output and the alarm output respectively.
The Omron E5CW-R1KJ temperature controller uses ON/OFF or 2-PID control method to regulate the temperature. You can select the control method by pressing the MODE key for more than one second. The control method indicator (PID) shows whether ON/OFF or 2-PID control is selected. ON/OFF control is suitable for simple applications where precise temperature control is not required. 2-PID control is suitable for complex applications where precise temperature control is required. It uses proportional, integral, and derivative actions to adjust the output according to the error between the set point and the process value.
To use 2-PID control, you need to set the PID parameters, such as proportional band, integral time, and derivative time. You can either manually set them using the front panel keys or automatically set them using auto-tuning or self-tuning functions. Auto-tuning is performed once when you press the AT key for more than one second. Self-tuning is performed continuously during operation when you press the ST key for more than one second. The tuning indicator (AT) shows whether auto-tuning or self-tuning is in progress.
Tips and Precautions
Here are some tips and precautions for using the Omron E5CW-R1KJ temperature controller:
Make sure that the power supply voltage is within 85 to 110% of the rated voltage (100 to 240 VAC).
Make sure that the thermocouple type matches the input type of the controller.
Make sure that the load current does not exceed 3 A for resistive load or 1 A for inductive load.
Do not use the controller in places where there is excessive dust, humidity, vibration, shock, or corrosive gas.
Do not touch the terminal block or other parts when power is applied.
Do not disassemble or modify the controller.
If you have any questions or problems, contact your OMRON representative.
