Whether the cable between the panel and the power board is broken or plugged incorrectly 4. Load short circuit or open circuit, probe ...

1. Mechanical The sensitive gas diaphragm box or thermal bimetal sheet is used as the temperature sensing element to form the temperature control switch of the mechanical contact. This kind of thermostat is more in the European and American markets, and only a few domestic manufacturers promote such products. Mechanical floor heating thermostats usually have contact currents of no more than 8A, which are suitable for ...

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 ...

1. Setup (XMT201-D): Press the SET button for 3 seconds to enter the inner parameter setting state. E: This parameter is the advance of heating stop when P = 0, when P is not equal to 0, the instrument is the intelligent PID working mode, and when P is not equal to 0, the E parameter is meaningless. 2.P: is the proportional band, that is, the proportional ...

Wiring Warning: If the instrument fails or an error occurs, which can cause a system failure, an external protection circuit is installed to prevent such accidents: In order to prevent damage or failure of the instrument, choose an appropriate fuse to protect the power cord and input and output lines from strong power shocks. Power supply ...

Fault 1, the indication is abnormal The float level gauge is not indicated properly and is a very common fault of the float level gauge. Usually there are the following manifestations: Phenomenon 1: The float level gauge in the atmospheric pressure workshop has the largest indication. Troubleshooting: The float was found to be ...

· 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. ...

Mechanical thermostat mainly refers to a temperature control method that adjusts refrigeration by rotating the button, with an expanding thermostat, which will automatically expand and contract according to the change of temperature, so as to control the power supply, the most primitive type, and the structure is relatively simple. Advantages of mechanical thermostats: ...

Model: CH402FS01-8*HN (for PECVD temperature control) 1) Single press SET: SV can be set (set temperature manually) 2) Press and hold the SET button for 2 seconds, ALI=1000 (absolute alarm temperature setting) and then press the SET button, ATU=1 (self-defining, self-interpreting a set of PID parameters) to exit ...

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 ...

In a variety of electronic control equipment, digital display has become an indispensable and important link. The electronic devices and corresponding driving circuits used for digital display are called digital displays. Commonly used digital displays include glow digital tube displays, fluorescent digital tube displays, projection ...

Wiring Notes: 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. ...

1. Press the ISET) button for 2 seconds to enter the parameter setting mode, press ISET until "LCK" is displayed, press the [] key to move the cursor to the thousands, and press the [] button to change the number of thousands from "0" to "1" to display "1000" to unlock. 2. Press the ISET button for 3 seconds to return to SV/PV display mode 3. Press [SET]+ ...

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. 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 ...

After heating for a while, the temperature does not change. Displays the ambient temperature of the site at all times (e.g. room temperature 25°C) In case of such a fault, first check whether the SV value setting value is set, whether the OUT indicator of the meter is lit, and whether the No. 3 and No. 4 terminals of the meter are 12VDC output with the "multimeter". ...

1. Heating for a period of time, the temperature does not change. Displays the ambient temperature of the site at all times (e.g. room temperature 25°C) In case of such failures, first check whether the SV value setting value is set, whether the instrument OUT indicator is lit, and whether the No. 3 and 4 terminals of the "multimeter" measuring instrument have 12VDC output.

1. The level gauge is adjusted normally, and it is found that the float is "absorbed" for a period of time in a certain position after it is put into use. This is mainly caused by the level gauge passing through the steel platform device and being spaced too close to the steel plate. Therefore, it is necessary to pay special attention to the level gauge to connect the pipe wall with the steel platform device.
