Fault 1: The thermostat does not turn on (does not light up) Analyze the causes 1. Wrong wiring 2. The voltage of the input terminal is not enough or the input terminal is damaged by empty opening and leakage 3. Whether the cable between the panel and the power board is broken or plugged incorrectly 4. Load short circuit or open circuit, probe ...

(1) For the indicator, also known as the display panel, the indicator plays the role of local display, convenient for long-distance observation of the actual situation of the liquid level, the indicator is generally bundled with the pontoon, easy to install. (2) It is a magnetic float, which is located in the pontoon and is in direct contact with the liquid to be measured, ...

1. Electrical parameters: (1) VDE, CQC, UL, TüVAC250V 50-60Hz 10A (resistive load) (2) ULAC125V 50Hz 15A (resistive load) 2. Operating temperature range: -50-270°C (optional), temperature accuracy: ≥ ±2°C 3. Reset and action ...

The temperature controller is an electrical switchgear that controls the temperature of an air-conditioned room. The temperature range in the air-conditioned room controlled by the temperature controller is generally 18°C--28°C. The temperature controller commonly used in window air conditioners uses the principle of pressure to push the contacts on and off. Its structure consists of bellows ...

RHK Recommended Product Models: Single-phase power conditioner THV-10（20A, 30A, 45A, 60A, 80A, 100A） 　　Ethernet communication converter COM-ME series 　　USB communication converter COM-KG 　　Digital Display Controller (Process/Temperature)

1. Thermostat output control power: The thermostat output control power is the first issue to consider when choosing a thermostat, which is related to the safety and stability of use, and may cause serious consequences if not selected properly, such as: fire. Thermostat products are marked with output control voltage and current, and the ...

1. Wall installation, the height is about 1.2 meters, generally on the same horizontal line as the electric lighting switch of the home. 2. Installed on a wall where the surrounding air flows freely, and is not affected by other heat sources (e.g. sunlight), air flow from doors and windows, or external wall temperature, etc. 3. Advance ...

1. Turn on the power supply of the smart thermostat, and the temperature displayed on the screen is the temperature at that time. Because the sensor is not in contact with other devices, but is directly exposed to the air clock, this is the current temperature: 31 degrees Celsius, which is not too hot. 2. At the bottom right of the display screen is the "starting temperature" setting ...

1. Do not wipe with acidic, alkaline and other corrosive liquids and water-containing rags when cleaning, so as not to damage the temperature controller and affect its normal use. 2. Do not decorate and cover the temperature controller. The thermostat has a built-in temperature sensor to sense the outside temperature. Therefore, Wen ...

1. The specific gravity of the liquid to be measured must be greater than the specific gravity of the float 2. The measured medium should not contain ferromagnetic impurities 3. The float level gauge should be installed in an unobstructed position when the float moves up and down 4. Magnets are not allowed to be close around the float level gauge, otherwise it will affect the float.

There are many types of instrumentation and have a wide range of applications in many fields. Because of this, there are many problems with the failure of instruments in the process of use, so it is necessary to pay more attention to the repair and maintenance of instruments and meters, which can effectively improve the performance of instruments and meters, and can extend the performance of instruments and meters.

1. Bellows or diaphragm air conditioner thermostat Fault Symptom: Poor contact or burning, resulting in the circuit cannot be connected; The frequent action of the contact arc and sticking causes the circuit to be unbreakable; The leakage of the thermostat in the temperature sensing chamber causes the contact to fail to operate and lose control ...

The thermostat shows a nonlinear relationship between the temperature and the actual temperature deviation: (1) The input type of the thermostat is selected incorrectly; (2) There is no calibration or calibration error in the analog input; (3) There is interference in the thermostat; (4) There is interference with thermocouples; (5) The use of quality is not ...

The working principle of dry-type transformer thermostats The dry-type transformer temperature controller is a new generation of controller designed for the safe operation of dry-type transformers. The controller adopts single-chip microcomputer technology, and uses three platinum thermal resistors embedded in the three-phase winding of the dry-type transformer to detect and display the transformer.

1. Grounding method: It is connected to the grounding metal parts of the equipment through the metal cover of the thermostat. 2. The thermostat should work in the general indoor environment where the relative humidity of the air is not more than 90%, and there are no corrosive gases, flammable gases and conductive dust. 3. The thermostat adopts contact ...

fold When the RKC thermostat comes out, it is a single-loop regulator, that is, it only has a heating function, which is called the basic meter, which is generally sent to the agent, and the agent will expand the multi-channel adjustment and alarm output control function, which is called "changing the meter" in the industry, so as to ensure that there is very little hardware cost.
