Quick Start Instruction E5CC OMRON 1.3 Selecting PID / ON-OFF Do you want accurate controls without the temperature overshooting? This is easily achieved by setting your controller as PID instead of ON-OFF. See Section 1.3.1 When the controller is set as PID controller, autotune must be run to get the correct PID values. For autotune, see Section 1.3.2. If accurate temperature control is not imperative, then you may set the controller to ON-OFF. Figure 7 illustrates the results of different regulation algorithms. Figure 7: PID vs ON-OFF 1.3.1 Setting up as PID controller To set the controller as PID controller, adjust the cntl (control) parameter. 1.
Press the 1st button (level button) for 3 seconds until in-t is displayed. 2. Then briefly press the 2nd button (mode button) several times until cntl is displayed. 3. As you can see, this parameter reads onof (ON-OFF). With the arrow up button change this to pid (PID). 4. Then press the 1st button again until the controller resets. The controller is now set as PID controller. We recommend changing the PID values. As mentioned earlier, the simplest way to do this is by using autotune See Section 1.3.2. 11
