OMRON Quick Start Instruction E5CC 1.1.1 Connecting sensor Pt100 If a Pt100 temperature sensor is used, connect it to terminals 4, 5, & 6. The controller expects a 3-wire Pt100, which generally has 2 identical colors and 1 different color. The identical colors go under terminals 5 and 6, the different color under terminal 4. If you have a 2-wire Pt100, then connect the temperature sensor between 4 and 5, with a bridging wire between connection 5 and 6. Thermocouple If you use a thermocouple, connect it to terminal s 5 & 6 Caution! A thermocouple has a + and – Incorrect connection may result in a negative or an incorrect value.
4-20 mA or 0-10 V A process value such as 4-20 mA or 0-10 V may be connected to terminal s 4 & 5 and 5 & 6, respectively. Figure 2: connecting sensor. For correct operation of the controller, please always indicate which type of sensor is connected. If this is not done correctly, the controller will display an s-err (sensor-error) message, or the incorrect value. For the correct settings, please see Section 1.2.1 6
