The first output method is relay output, which is output for temperature control through the switching signal of the relay on/off, which is used to directly control the load less than 5A, or directly control the contactor and the intermediate relay, and control the high-power load externally through the contactor. The second ...

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.

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. 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]+ ...

1. There is no display of dry-type transformer thermostat Cause of failure: (1) The power supply of the thermostat is not connected; (2) The fuse is blown out. Solution: (1) Turn on the power supply; (2) Replace the fuse. 2. The dry-type transformer thermostat shows that one or three phases are flashing and displays "-OP-" ...

(1) Before use, first check whether the level gauge is within the verification cycle, otherwise, it should be calibrated, and replaced in time if it is unqualified. (2) The sensor should be installed horizontally, and the length of the lower entry should meet the technical requirements. (3) The connection between the sensor and the explosion-proof junction box should be tightened and tightened.

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. Set temperature: Press the SET button to set or view the temperature set point. Press the SET button digital tube characters to start flashing, indicating that the instrument has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, long press the △ key or ▽ key The data will change rapidly, press the SET key again ...

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 ...

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...

Dual display set temperature and process temperature 2. General Digital Programmable Temperature ...

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. Select the appropriate level gauge First of all, it is necessary to choose the appropriate level gauge. The following factors should be taken into account in the selection of a level gauge: Measure the properties of the medium: e.g., temperature, pressure, viscosity, corrosiveness, etc. Measuring range: i.e. the height range of the liquid ...

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 ...

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