  • Page 4: Chapter 1 Overview

    Chapter 1 Overview 1-1 General Description The Smarter Logic PID microprocessor-based controller incorporates a bright, easy-to-read 4-digit LED display. The front LED display can be programmed to indicate either the process value or set point value. Smarter Logic technology enables a process to reach a predetermined set point in the shortest possible time, with minimum overshoot during power-up or external load disturbance.
  • Page 5 Fast Sampling Rate The sampling rate of the input A to D converter reaches 5 times/second. This fast sampling rate allows this series to control fast processes. Smarter Logic Control The function of Smarter Logic control is to automatically adjust the PID parameters from time to time. These dynamic adjustments are made in order to tune the output value to be more flexible and adaptive to various processes.

  • Page 14: Chapter 2 Installation

    Chapter 2 Installation Dangerous voltages capable of causing death are sometimes present in this instrument. Before installation or beginning any cleaning or troubleshooting procedures the power to all equipment must be switched off and isolated. Units suspected of being faulty must be disconnected and removed to a properly equipped workshop for testing and repair.

  • Page 15: Wiring Precautions

    2 - 3 Wiring Precautions Before wiring, verify the label for correct model number and options. Switch off the power while checking. Care must be taken to ensure that the maximum voltage rating specified on the label is not exceeded. It is recommended that the power of these units be protected by fuses or circuit breakers rated at the lowest value possible.

  • Page 16: Power Wiring

    2-4 Power Wiring The controller is designed to operate at 11-26 VAC / VDC or 90-250 VAC. Check that the installation voltage corresponds with the power rating indicated on the product label before connecting power to the controller. Near the controller, a fuse and a switch rated at 2A/250VAC should be equipped, as shown in the following diagram., ETR-4100 ETR-8100 ETR-9100...

  • Page 25: Dwell Timer

    3-7 Dwell Timer Output 2 can be configured as dwell timer by selecting TIMR for OUT2. As the dwell timer is configured, the parameter SP2 is used for dwell time adjustment. The dwell time is measured in minutes, ranging from 0.1 to 4553.6 minutes.

  • Page 26: Digital Filter

    3- 9 Digital Filter In certain applications, the process value is too unstable to be read. To improve this, a programmable low pass filter incorporated in the controller can be used. This is a first order filter, with the time constant specified by FILT parameter.

    3 -11 Auto-tuning The auto-tuning process is performed at set point. The process will oscillate around the set point during the tuning process. Set a set point to a lower value if overshooting beyond the normal process value set point is likely to cause damage. The auto-tuning is applied in the following cases: Initial setup for a new process When set point is changed substantially from the previous auto- tuning value...
