User manual OMRON K8AB-TH

[. . . ] · Reduce the number of models by using multi-input support for thermocouple or Pt100 sensor input. Selecting Functions and Modes · The following settings are provided: alarm mode (upper limit/lower limit), enable/disable latch, °C/°F, relay output non-fail safe/fail safe, setting protection. Terminal Wiring with Ferrules · Wire with 2 × 2. 5 mm2 solid wire or 2 × 1. 5 mm2 wiring ferrules. Model Number Structure Model Number Legend K8AB-TH1Setting Range 1: Low-temperature range (0 to 399°C: setting in increments of 1°C) 2: High-temperature range (0 to 1800°C max. : setting in increments of 10°C) 4. [. . . ] The protection function can be released by pressing the output latch reset button on the Temperature Monitoring Relay for at least 5 s or by turning ON the input to the external input terminal for at least 5 s. The power indicator will light while the protection is being reset. Dimensions Note: All units are in millimeters unless otherwise indicated.

Doing so may occasionally result in minor injury due to electric shock. Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur. Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. Loose screws may occasionally result in fire. Tighten terminal screws to the specified torque of 0. 54 to 0. 55 N·m. Set the parameters for the Temperature Monitoring Relay so that they are appropriate for the system being monitored. If they are not appropriate, unexpected operation may occasionally result in equipment damage or accidents. Use the following procedure to make the Temperature Monitoring Relay settings. · Make settings for the Temperature Monitoring Relay so that they are appropriate for the system being monitored. 14. Approximately 30 minutes is required for the correct temperature to be detected after turning the power supply to the Temperature Monitoring Relay ON. Turn the power supply ON at least 30 minutes prior to actually starting monitoring. 15. To avoid inductive noise, keep the wiring for the Temperature Monitoring Relay's terminal block away from power cables carrying high voltages or large currents. Also, do not wire power lines together with or parallel to Temperature Monitoring Relay wiring. Using shielded cables and using separate conduits or ducts is recommended. 16. Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component). When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the Temperature Monitoring Relay.
