Overview of the RLC thermostat

· Wiring warning: - If the instrument fails or an error occurs, which can cause a system failure, install external protection circuits to prevent such accidents; - To prevent damage or failure of the instrument, use appropriate fuses to protect the power cord and input/output cord from strong power shocks. ...

　　The power indicator is normal, but the temperature control meter has no on-screen display. This kind of fault is mostly caused by the heating of the voltage regulator element (7805 or 7812) of the temperature controller during long-term use, resulting in a break point in the solder joint, and sometimes a virtual soldering occurs at the factory, resulting in re-soldering. ...

Thermocouples, RTDs, analog and other signals are freely inputted, and the range can be set freely; The software zeros the full degree, the cold end measures the temperature separately, the amplifier is self-stabilizing, and the display accuracy is better than 0.5%FS; Fuzzy theory combined with traditional PD method, fast and stable control, advanced tuning ...

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; Leakage of thermostat in the temperature sensing chamber, causing the contacts to fail to operate and lose control ...

1) The LCD interface is too large or the display symbols are not proportional or standard. 2) The terminal blocks or circuits (components) that control the output cannot withstand large currents. 3) The cable of the external sensor (ground probe) is a thin and flexible wire, which cannot be inserted into the embedded pipe, and it is also a hidden danger for future maintenance. ...

1. The installation of the level gauge must be vertical to ensure that the inner pontoon can move up and down freely in the pipe body. 2. Install a shut-off valve between the container and the liquid level gauge to clean and overhaul the liquid level timing to cut off the material. 3. No magnets are allowed to approach around the main body of the pontoon level gauge, otherwise ...

1) Separate households are independently heated, and floor heating is installed in small households, and boiler temperature control is applicable. 2) Separate households independent heating duplex building installation floor heating room temperature control. 3) Separate households for independent heating, large duplex villas are suitable for floor heating stratified temperature control. ...

peculiarity 1. Thermocouple, RTD, analog and other signals are freely input, and the range can be set freely. 2. The software adjusts the full degree, the cold end measures the temperature separately, the amplifier is self-stabilizing, and the display accuracy is better than 0.5%FS. 3. Fuzzy theory combined with traditional PID method, fast control ...

1. The power indication is normal, but the temperature controller has no screen display. Most of this fault is caused by the heating of the voltage regulator element (7805 or 7812) on the thermostat during long-term use, which leads to the breakpoint of the solder joint, and sometimes it is caused by the phenomenon of virtual soldering at the factory, and the main re-soldering can be done. 2. Temperature controller ...

1) Measure the function Its temperature measurement scale is mainly between -20 °C and 80 °C, and the humidity measurement scale is mainly between 20% RH and 99% RH. In addition, it has a temperature resolution of 1°C and a humidity of 1%RH. 2) Parameters and data display functions Temperature and humidity control ...

The correct selection of the level gauge can ensure the better use of the level gauge. What kind of level gauge should be selected according to the physical and chemical properties of the fluid medium to be measured? What is the diameter of the level gauge, the flow range, the lining material, the electrode material, and the output current? can adapt to the ...

Japan RIKA RKC REX-C400 temperature controller product introduction REX-C400 Digital Thermostat RKC PID Temperature Controller Thermostat (SSR Output) + Type K Thermocouple + *Large 40A SSR Relay 1. Dual display set temperature and process temperature 2. General Digital Programmable Temperature ...

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. For thermocouple input, the corresponding compensation wire should be used. 2. For RTD input, 3 wires with low resistance and no difference should be used 3. The input signal line should be far away from the power line of the instrument. Power supply and load lines to avoid noise interference 4. The instrument power cord is usually ...

1. Thermostat contact contact failure Poor contact of the thermostat contacts will cause the compressor to not operate properly. If the contacts are sticky, the compressor will fail without downtime. For this, you can use a small screwdriver to open the metal shell of the thermostat, and then use a fine abrasive cloth to polish the surface of the contacts ...

1. For thermocouple input, the corresponding compensation wire should be used. 2. RTD input, 3 wires with low resistance and no difference should be used. 3. The input signal line should be far away from the power line of the instrument. Power supply and load lines to avoid noise interference. 4. Instrument power cord ...

First, the selection of the orientation of the thermostat device 1. Easy to operate locally; 2. It can include the average temperature of the local area; 3. Localities with more human activities; 4. It can avoid cold and heat sources; That is to say, the orientation of the device should be far away from radiators, away from doors and windows...

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, ...
