A freon leak detector is a device used to detect and locate leaks in cooling systems that use freon or other refrigerants. Freon, also known as chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC), is commonly used as a coolant in refrigeration and air conditioning systems. The leak detector works by sensing the presence of freon gas in the air. It typically uses a heated diode sensor or an infrared sensor to detect the gas. When a leak is present, the freon gas escapes and is detected by the sensor.
Freon leak detectors play a crucial role in maintaining the safety and efficiency of various systems that utilize refrigerants. Freon leak detectors are essential tools in the HVAC (Heating, Ventilation, and Air Conditioning) industry for detecting and locating refrigerant leaks. Timely identification and resolution of freon leaks help prevent environmental damage, improve system performance, and ensure compliance with safety regulations. These devices are designed to detect and locate leaks of Freon, a type of refrigerant commonly used in cooling and air conditioning systems.
| (1) The controller should be installed in the duty room or places where people often come and go, and should be supervised by special personnel; users and non-professionals are not allowed to disassemble the instrument at will. | Maintenance Notice & Precautions |
| (2) When the controller is in normal monitoring state, please do not cut off the power frequently. Regularly check whether the controller is working normally, and the cycle is recommended to be once every three months. | |
| (3) Do not change the internal parameters of the controller arbitrarily, so as not to affect normal use due to parameter mismatch. If there is a fault and needs to be removed for maintenance, please make sure that the controller is powered off. |
Troubleshootings and Solve Methods: When the controller sends out a fault alarm signal, the on-duty personnel should first perform the “silencing” operation, and then handle it according to the reported fault address and fault type according to the following table.
| Errors | Cause Analysis | The Solution |
| “E0” | The circuit connected to the detector is short-circuited | Check the bus loop, there is a short circuit |
| “E2” | Current address detector communication failure | Check whether the connecting wire of the detector is disconnected or loose. |
| “E5” | Memory chip failure in the current address sensor | Replace sensor module |
| “E3” | Current Address Detector Sensor Malfunction | Replace sensor module |
