First, the maintenance of the inverter must first check whether the sound in the operation of the motor is abnormal, including, whether the motor is in operation to form a sensation.
2. Check whether the natural environment of the inverter installation has changed. For example, whether the operating temperature is normal. Anyone who understands the maintenance of Delta inverters should know that the operating temperature of inverters is generally specified in the range of -10°C to +40°C, and it is advisable to go up and down 25°C.
3. Check whether the inverter heat exhaust fan is in normal operation, for example, whether the heat exhaust safety channel of the inverter is Xiaochang, and whether the main parameters of the inverter on the indicated control panel are normal.
Fourth, the inverter maintenance also has to check whether the inverter is high temperature. You can use an infrared thermometer to check whether the radiator of the inverter is high temperature or whether it has a strong odor. It is also necessary to check whether there are common fault alarms in the operation of the inverter.
5. The maintenance of Delta's inverter should also ensure that the filter screen of the air inlet pipe inside the low-pressure complete set of equipment is exempted on time on a daily basis. Keep the control box and inverter in excellent finishing condition for a long time. Because it can reasonably eliminate the area dust on the inverter, it can also avoid the dust from entering the inverter, reasonably remove the oil stains of the inverter fan, and reduce the occurrence of heat exhaust problems.

The benefits of using an inverter – Delta inverter
1. Speed regulation of general motor: By changing the input voltage and frequency of the three-phase asynchronous motor, its speed can be controlled. Generally, when the motor is at low speed, the temperature rise becomes larger due to the decrease in the power of the cooling fan, and the motor load should be reduced according to the frequency.

Problems with Delta's compact pressure transmitters
1. The transmitter does not return to zero under no pressure?
Answer: The cleaning method is to remove the transmitter from the device position, investigate whether the zero position is normal, and replace the pipeline sealing ring if it is normal. Check together whether the transmitter is perpendicular to the piping assembly, and if not, adjust the transmitter zero.

Correct use of Delta inverter in operation
(1) When the speed of the motor is controlled by the Delta inverter, the noise and temperature rise of the motor are higher than that of the frequency of the motor. When the motor is running at low speed, because the speed of the motor blades is low, the temperature rise of the motor becomes high.
