How to set the parameters of the RKC fb900 thermostat

The instrument can be cleaned only after the power is off; To remove stains from the monitor, use a soft cloth or cotton paper; The display is easy to be scratched, and it is forbidden to use hard objects to operate the panel buttons, otherwise the keys will be damaged or scratched. ...

　　Analog-to-digital converters The analog-to-digital converter comprises a first transmission circuit, which receives an input voltage and an output clock signal, which is phase-shifted, depending on the input voltage, and a second transmission circuit receives a reference voltage and an input clock signal, and outputs a reference clock signal, which ...

1. Electromagnetic induction (refers to the coupling of magnetism). There is a strong alternating magnetic field in the surrounding space of high-power transformers, AC motors, high-current power grids, etc., and the closed loop formed by the lines of the control system (detection, transmission, conversion, regulation, calculation, execution, auxiliary, display, etc.) is located in the ...

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...

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 level gauge is composed of five parts: float, traction cable, guide pulley, hammer pointer, display ruler or magnetic flap. 1. Float: The float is welded with two stainless steel (or carbon steel) fasting cones and one stainless steel (or carbon steel) fasting cylinder.

1. After heating for a period of time, it is found that the temperature has not changed, and the temperature has been displayed at the time of the ambient temperature. In this case, you need to check that the SV value setting value is set, whether the OUT value indicator of the meter is not lit, and whether the No. 3 and 4 segments of the universal meter are 12VD ...

Faulting and troubleshooting of vapor pressure temperature controllers (1) Common faults and common faults of the vapor pressure type temperature controller include contact burning or adhesion, failure of the mechanical transmission mechanism and leakage of temperature sensor in the temperature sensing tube. Its detection method is: put the thermostat knob in a parking position, and use ...

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 ...

Common faults of thermostats 1. There is no display when the power is on. This type of problem first determines whether the power supply is available and whether the power supply matches the power supply required by the thermostat, and then checks whether the wiring is secure. The problem is still there, then it is the problem of the thermostat itself. 2. There is a display, and the control is wrong. This...

1. Heating for a period of time, the temperature does not change. The ambient temperature of the site (e.g. room temperature 25°C) is displayed at all times. In case of such failures, first check whether the SV value setting value is set, whether the 0UT indicator light of the meter is lit, and whether the No. 3 and No. 4 terminals of the meter with the "multimeter" are 12VD ...

The float level gauge is widely used, mainly used in petroleum processing, food processing, chemical industry, water treatment, manufacturing, electric power, papermaking, metallurgy, ships and boilers and other industrial automation processes to measure and control the level. 1. Pay attention to the specific working conditions. As introduced ...

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. First of all, determine the set temperature of the thermostat and make sure that it is the same as the temperature you need. 2. Recognize the operating form of the thermostat, usually there are two forms of cooling and heating, and choose the corresponding form according to the demand. 3. Acknowledging the operating condition of the thermostat, usually with active ...

1. Set temperature: Press the SET button to set or check the temperature set point. Press the SET key digital tube character start flashing, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key data will change rapidly, press the SET key again ...

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, the power supply line and the load line to avoid noise and annoyance. 3) The power cord of the instrument is generally annoyed by the power supply. 4) Instrument complement ...
