What is the fault of the heat shrink machine temperature controller showing 400?

If the heat shrink guitar shows more than 400 on it, then you will have to lose the power, only after the power is off, you can turn off the power, and then see what alarm will appear.

The heat shrink machine temperature controller shows 400

Normal should be the maximum temperature set.

If not, it is recommended to check the fault code of the manual.

The power indication is normal, but the thermostat has no on-screen display. Most of the faults are caused by the heating of the regulator element (7805 or 7812) on the thermostat during prolonged use.

Causing breakpoints in solder joints.

Sometimes it is caused by the phenomenon of virtual welding when leaving the factory, and the main re-welding is sufficient.

The thermostat shows normal, the metal sleeve thermometer, the marine thermometer, the V-type thermometer, the copper sleeve thermometer can not be added, generally the heating element is damaged, and in the case of confirming that the heating element is not a problem, the relay is mostly bad (mostly in the instrument with a heating power of more than 1000W).If the relay is good, the relay drive element (9013) is bad. For solid state relays.

It is easier to be damaged, and there is less burning for triacs.

When the temperature controller shows that the temperature is much higher or much lower than the actual temperature, this phenomenon is usually a temperature sensor.

If it is damaged, it can be replaced.

Check whether the wiring between the thermostat and the thermocouple is good, and then use the replacement method to judge.

Hello, there may be a problem with the compressor. Call the after-sales customer service, and they will arrange personnel to come to the repair.

It may be a temperature design. You can check whether the temperature design** is faulty.

The cause of the ERR-04 is due to the low voltage of the battery.

According to your description, this situation belongs to the meter error**, err-04 means that the meter battery voltage is low, it may be caused by the abnormal meter, in order to avoid the subsequent impact on your electricity consumption and billing, it is recommended that you call the 24-hour power supply service **95598 to reflect, the power supply department will have relevant staff to follow up.

In view of your problem, the first thing to look at is how you use this device. Then check the fault code according to your device model. This can be more accurate.

Because the model of each device is different, the fault is different. Well, some say it's a dead battery. It is said to be caused by dry burning.

So let's take a look at the specific model according to the model. The professional maintenance department will test it. Hope it helps, it's just a personal opinion.

It's very simple, it means that there is an accident on the external line, and the dry boiling protection lock is turned on, and when the electric water heater forgets to add water or the water added is boiled dry for a long time, there is an anti-dry burning protector (temperature too high protector) that will automatically jump and stop. But there is also a high chance of burning out the water heater. See for yourself what is going on.

Hello! The temperature controller ERR4 is "temperature dry burn locked"**. Hope it helps.

Follow the following steps to solve the problem: first, look at the temperature controller setting, see if the set sensor model is correct, and then see if there are any errors in other settings, such as error adjustment, etc. The second look at the transmission distance, the distance exceeds the range of the sensor, it is definitely not accurate, I just encountered this problem and has not solved it.

Ask the master to solve it together. Third, look at the sensor, whether the sensor is faulty. Fourth, look at the connection line between the sensor and the temperature controller, if it is in an industrial environment, it is necessary to use a shielded signal line, that is, the kind of wire with a layer of copper wire.

The temperature control of the RS400 thermostat fluctuates too much, such as setting 100 degrees, his control shows 90 to 110 degrees, and can be directly adjusted to 110 degrees to observe for a while.

400 temperature controller, the temperature control fluctuates too much, such as setting 100°, its control display is 90 to. 110°。

Its actual control temperature is between 98 and 102 degrees, what parameters should be set? Mathematics.

If the fluctuation of disagreement is too great, the words in this one are not too conducive to its form.

RS400 temperature control one degree, if the control fluctuation is too large, set 100 degrees to display 90 10 billion, this is not able to handle.

If the temperature control is 1° and the fluctuation is large, if it is set to more than 100, its control will display 90 to 110°, how to deal with it? Then you can turn it up a little bit.

Find a way to raise its temperature, as for what way to eat technical things.

This path control fluctuates too much, set 100 degrees, and its formula shows 90 to 110

The temperature control fluctuates too much if it is set to 100 and its control shows nine.

The temperature settings fluctuate too much, and I don't know what to do? Look** just know if you don't say it.

If you control it, I think.

That means that there is a problem with his temperature control, you have to see if there is a problem with his background, and then check this specific situation.

The temperature control of the RS400 thermostat fluctuates too much, such as setting 100 degrees, and his control supervision and inspection this year.

When you get out of the plane, there are a lot of people on the plane, and look at your bank card.

The air conditioning temperature controller is indispensable in many devices today, and it plays a very key role. As more and more business users and manufacturers have a large demand for this kind of device, its information has also attracted the attention of different groups. In the process of using this kind of equipment, it may have a variety of failures due to different external factors, so let's briefly understand the common faults of air conditioner thermostats.

Air conditioner temperature controller fault 1: The device has no display after powering on

Solution: 1. First of all, check whether the terminals of the equipment have been connected to the neutral live wire, and you need to ensure that the neutral live wire power supply can work normally. 2. Then start to check whether the cable between the LCD motherboard and the equipment drive power supply is loose, and relevant tightening measures need to be taken.

3. Pay attention to whether the switch of the thermostat has been turned on and meets the specified standards. 4. When wiring the air conditioning temperature controller, it is necessary to check the relevant voltage, current and other problems of the wiring power supply in advance.

Air conditioner temperature controller fault 2: There is a discrepancy between the wind speed displayed by the temperature controller and the actual wind speed

Solution: You can check whether the terminals of the air conditioner thermostat are connected in the wrong order, and if so, you need to reconnect them in the correct order and method.

Air conditioner temperature controller fault 3: The device display is normal, but there is an error in control

Solution: 1. First of all, you need to check whether the cable of the equipment is connected well and whether the contact is good. 2. Then you need to check whether the connection of the cable is correct.

Air conditioner temperature controller fault 4: The equipment has a deviation in temperature detection

Solution: 1. First of all, you need to use the calibration data of the equipment for the temperature before, and then re-measure it, and then compare it. 2. Check whether the sensor configured by the device has a fault problem.

3. See if it is because the installation location does not meet the specified standards and is not suitable for the detection of relevant temperatures, and it is recommended to improve the installation environment.

With the advent of the 21st century, almost every household has installed household appliances such as air conditioners. Whether it is a household air conditioner or a commercial air conditioner, installing such a temperature controller is more convenient for everyone to master the temperature regulation. You must know that now the air conditioning temperature controller has become one of the devices used by home users and commercial users, and the above four common faults are easy to encounter in the process of daily use.

We hope that through our brief introduction, we can find out the cause of this kind of failure problem as soon as possible, and make timely and effective treatment.

After years of use, the air conditioner will inevitably have various small conditions, so it must be repaired in time, otherwise the problem will become more and more serious. You can use methods such as looking, listening, touching, and measuring to check what is wrong with the air conditioner. According to relevant statistics, the common faults of air conditioners are as follows:

1. Refrigerant leakage;

2. Leakage of the line;

3. Blockage of refrigeration system, air filter, air inlet and air outlet;

4. The electrical line is disconnected;

5. Burning group of compressor and fan motor;

Summer is here, and people are turning on their air conditioners, ready to enjoy the rare refreshment of summer. But at this time, if the air conditioner is not cooling, then it is really heartburn. There are generally two reasons why the air conditioner cannot be cooled, which may be caused by a lack of refrigerant, or the air conditioner has not been cleaned for a long time.

At this time, you can first take a look at the situation of the filter and heat sink, if it is seriously dirty, you can clean it first to see how the refrigeration effect is. If it still doesn't work, it is necessary to consider whether it is caused by the lack of refrigerant, at this time, it is necessary for professionals to use a measuring tool to measure first, see how much is missing, see if there is a leak, etc., and then repair it, and then replenish the sufficient amount of refrigerant.

Generally speaking, the outdoor unit of the air conditioner will only drip, but if the indoor unit at your home is dripping, then everyone should pay attention. Generally speaking, there are two main reasons for the dripping of the indoor unit: 1. The installation of the air conditioner is unbalanced, and if it is in a horizontal position, this situation usually does not occur.

2. Another reason is that the drain pipe of the air conditioner is blocked or bent, but the internal water cannot flow out. In this case, the user can take a look at it first, and the problem of the drain pipe can usually be solved smoothly.

Generally speaking, the air conditioner will not make a lot of noise during operation. If the air conditioner in your home is making a lot of noise while working, then it must be out of order. There are generally two reasons for the noise of the air conditioner:

1. The first reason is that the bracket of the external machine is not stable, or it is not in a horizontal position, which will make the external machine noisy when it is running, and it is necessary to rearrange it at this time, and tighten the unstable bracket with screws; 2. Another reason is that the wind speed of the air conditioner is relatively large, and the speed of the air outlet is also large, resulting in a relatively loud noise. At this point, you need to reduce the wind speed, and you can do it.

Hello, may I ask what is shown above** or what.

If the monitor is faulty, it is usually a problem with the sensor, you can take the sensor out and wipe the rust on it.

Please, give a **. It's just that you can't see it at all!

Your meter shows up? There's no picture.,There's no **.,I can't see it.。

The table shows what this sign is.

How come we don't see this meter shows what fault it is? So I can't guess.

Dry-type transformers operate normally with a slight rhythmic humming sound that varies with the alternating current frequency. If the sound is too loud, it means that there is a short circuit fault. The load can be disconnected, and if the sound is normal, it means that the load is short-circuited.

If the sound is abnormal, it means that the primary is short-circuited. or caused by excessive voltage. If there is a squeaky sound, it means that there is an internal ignition fault.
