Precautions for the use of RKC thermostats

1. Set temperature: press and hold the SET key, at this time the tube character begins to flash, proving that the instrument has entered the set state, increase the up button, decrease the down button, and press and hold the up and down buttons to quickly change, when the desired temperature is reached, then press the SET button The instrument is set. 2. Return control: press SET ...

1. Lower limit deviation alarm setting: press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint. 2. The upper limit deviation alarm is set ...

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 ...

Model definition FB90②③*④4⑤⑥⑦⑧⑨-0( CODE 8N-4*4NN5/A1-F801/Y control "(1)(2)" indicates Output 1 and Output 2 classes M: Relay output V: Voltage pulse output 5: 0-10V 8: 4-20mAN: No output “ ...

1. Welding and installation of the lower support of the guide wire: determine the position at the bottom of the container according to the requirements of the movement direction of the float of the level gauge, and weld or rivet the lower support of the fixed guide wire. If the equipment does not have welding conditions, the heavy anchor fixing method can be used to fix the guide wire under the support. For example, the liquid level wave in the container ...

1) For RTD input, 3 wires with low resistance and no difference should be used. 　　2) The input signal line should be far away from the power line of the instrument. Power supply and load lines to prevent noise disturbances. 　　3) The power cord of the instrument is generally disturbed by the power supply. 　　4) Instrument complement ...

1. First of all, the digital display should be installed on the cabinet, so the overall coordination should be considered, too large may not fit, too small to see the display numbers. 2. In addition, the large size of the instrument is generally more expandable, the same function price may be expensive, the small size of the instrument may be ...

In the design of power converter, firstly, the circuit topology is determined according to the load requirements, and the composition and backup mode of the power converter are determined, and the main parameters of the power converter are input voltage range, output voltage accuracy, load stability, voltage stability, output ripple, efficiency and dynamic.

1. Under what circumstances should I use a thermostat to expand the module? The gradual development of the heating field is now very well recognized, and more and more users have begun to install electric heating, of course, when installing electric heating for users, they have also encountered some headaches. For example, a large area ...

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. ...

In general, the following points should be followed when installing a float level timer: 1. In order to prevent the float from sliding or hitting the sealed tube at high speed during transportation, causing the measuring belt to fall out, the instrument is fixed at the bottom of the sealed tube with a clamp before leaving the factory, and the magnet is on the top of the sealed tube.

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 ...

Generally, there are three buttons to provide the need for setting, one is the Set button, press it once to enter the setting state. The other two offer upward and downward temperature adjustments, which can be adjusted to any temperature point. After adjusting to the desired temperature point, press the Set button again to confirm. 1. Turn on the smart thermostat ...

In winter, the surface of the power plant's measuring instruments is frozen and condensed, which can lead to poisoning, fire and even explosion. Therefore, the cold and freeze protection of the appearance of the instrument is particularly important. First, the selection method (1) Choose the appearance with insulation device. According to the category of appearance ...

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 ...

(1) Size selection When replacing the thermostat, choose according to the original size; The newly added thermostat should take into account the overall coordination of the cabinet installed, too large to fit, too small to see the display, the same function of the thermostat, the price of large volume will be more expensive, small size may function expansion...

The normal operation of the instrument is inseparable from the on-site maintenance relationship, especially some important process links, once there is a leak, it will greatly affect the quality of the product, resulting in heavy losses. First of all, it is common to install both remote and field-indicated level gauges on important tanks.

First, the use of electronic temperature controller The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, and these resistors have their own advantages and points. Home Air Conditioner ...

1. Confirm the angle sample first. See where the angle of the sample is today. 2. Pick up the thermostat, first confirm whether the switch of the thermostat is tight, stuck, whether the white dot falls off, whether there is sound when the thermostat contacts are in contact, and if there is no sound, there should be two possibilities! ...

1. Power conversion: convert the voltage (rated 100V) and current (rated 5A or 1A) of the transformer into voltage (several volts) to meet the requirements of weak current components. 2. Isolation: current, secondary side security, and work grounding are used to ensure the safety of people and equipment, while weak current ...
