7. HowInstallation and Commissioning

temperature sensorIt should be securely mounted on theTop of the tankmaybeWinding hot spots, to ensure good contact.
Temperature control mainframeRecommended for installation inHigh Voltage Cabinet PanelThe operation is easy to observe.
connect a wireIt should be carried out strictly according to the instructions to avoid signal interference and misconnection.
adjust components during testingdefault settinggive a warning,(of a circuit breaker or switch) trip,Fan startupand other thresholds, one by one to test each function is normal, to ensure that the data is accurate and the action is sensitive.

caveat

  • Sensing probes should be calibrated periodically to maintain sensitivity
  • Strictly prohibit operation with electricity to ensure personal safety
  • Ambient temperature and humidity should meet the requirements of the equipment

8. CommonTroubleshooting and Maintenance

  • Sensor failure: Replacement or calibration of sensors
  • Display Exception: Check power, wiring, panel settings
  • Fan does not operate: Check relay outputs and fan body
