How to solve the open circuit fault of Omron oxygen generator

The answer has been found for you, please check it. Oh, thank you! Omron Household Oxygen Generator 1/4 Faults and Maintenance Methods The machine does not run, and the power indicator light is on: Cause: The compressor is overheated, which causes the compressor to turn on overheating protection and automatically stop. Troubleshooting: The machine runs without stopping for a long time, and suddenly stops one day, and can be restarted after it is shut down and cooled. This is because the working time of the compressor is too long, which leads to the overheating of the compressor, which makes the compressor turn on the overheating protection and automatically stop. Therefore, it is necessary to avoid the continuous operation of the machine for a long time without stopping, and it is best to run for 12 hours and stop for 30 minutes. Two-quarters of the machine is running, but there is no oxygen output. The flowmeter floats at the bottom position or a certain position, and the flowmeter knob does not move. Reason: 1 The soaked bottle core is blocked by scale and is not ventilated; 2. The flowmeter knob is closed or damaged.

Troubleshooting: 1. Turn on the power switch of the oxygen generator to make the machine run. Unscrew the humidifying bottle and see if the float of the flowmeter is adjustable. If yes, the wetting bottle core is blocked by scale, and the hole of the wetting bottle core is opened with a needle. Instead, check the flowmeter vortex.

Possible fault: 1, inverter output circuit is grounded or short-circuited; 2. Vector control mode and parameter-free identification; 3. The acceleration time is too short; 4. The manual torque is increased or the V/F curve is not suitable; 5. Low voltage; 6. Start the rotating motor; 7. Sudden loading during acceleration; 8, the frequency converter selection is small; Fault analysis: 1, the damage of rectifier module is usually due to grid voltage or internal short circuit. Replace the rectifier bridge under the condition of eliminating the internal short circuit. When dealing with faults on site, it is important to check the situation of the user's power grid, such as the voltage of the power grid and whether there are welding machines and other equipment that pollute the power grid. 2. The damage of inverter module is usually caused by motor or cable damage and drive circuit failure. After repairing the drive circuit, replace the module when the drive waveform is in good condition. After replacing the drive board in the field service, pay attention to check the motor and connecting cables. Only when there is no fault can the frequency converter run. 3. It is usually because the switching power supply or soft charging circuit is damaged that the DC circuit has no DC power supply. If the starting resistor is damaged, the operation panel will also be damaged. 4. Display overvoltage or undervoltage is usually caused by lack of input phase, aging circuit and damp circuit board. The solution is to find out its voltage detection circuit and detection point and replace the damaged device. 5. Overcurrent or short circuit to ground is usually caused by the damage of current detection circuit. Such as Hall element, operational amplifier circuit, etc. 6. Overcurrent is usually caused by the damage of the drive circuit or inverter module when the power supply and the drive board are started. 7. No-load output voltage is normal, and overload or overcurrent after loading is usually caused by improper parameter setting, aging of driving circuit, module damage and other reasons.

Omron household oxygen generator 1/4 machine is not running, and the power indicator light is on: Cause: The compressor is overheated, which makes the compressor turn on the overheat protection and automatically stop. Troubleshooting: The machine runs without stopping for a long time, and suddenly stops one day, and can be restarted after it is shut down and cooled. This is because the working time of the compressor is too long, which leads to the overheating of the compressor, which makes the compressor turn on the overheating protection and automatically stop. Therefore, it is necessary to avoid the continuous operation of the machine for a long time without stopping, and it is best to run for 12 hours and stop for 30 minutes. Two-quarters of the machine is running, but there is no oxygen output. The flowmeter floats at the bottom position or a certain position, and the flowmeter knob does not move. Reason: 1 The soaked bottle core is blocked by scale and is not ventilated; 2. The flowmeter knob is closed or damaged. Troubleshooting: 1. Turn on the power switch of the oxygen generator to make the machine run. Unscrew the humidifying bottle and see if the float of the flowmeter is adjustable. If yes, the wetting bottle core is blocked by scale, and the hole of the wetting bottle core is opened with a needle. Otherwise, check the flowmeter of the cyclone; 2. Turn the knob of the flowmeter counterclockwise to see if the knob rod of the flowmeter rotates accordingly. If it does not rotate with it, the flowmeter will be damaged. Contact the maintenance personnel of the manufacturer to replace or repair the flowmeter. 3/4 customers obviously felt less gas when using it: reason: 1. Humidifying bottle leaks air; Troubleshooting: Turn on the power switch of the oxygen generator and adjust the flowmeter to the 3-liter position. Plug the oxygen outlet end of the humidifying bottle tightly by hand. The float of the flowmeter should move downward, and the humidifying bottle will squeak (the safety valve is opened), otherwise the humidifying bottle will leak. Tighten the bottle or replace the humidified bottle; Three-quarters of the machines are not running, and the power indicator light is not on. Cause: The power supply is not connected; Troubleshooting: Check whether there is electricity in the power socket, whether the fuse is damaged and whether the power cord is broken.
