Routine maintenance of Delta UPS power supply equipment

1. The touch screen is controlled by PLC inverter 1. Now the general control of the inverter needs to use PLC to communicate with the inverter, read the information of the inverter, and then the touch screen communicates with the PLC in order to complete the control of the inverter to start, stop, and monitor the operation of the inverter.

Product range: CP/CH/CT/C2000/C200/MS300/MH300/VE/ED/VJ Problem Code: CE1 Problem Description: Communication is abnormal Solution: 1. Communication error: RS-485 Modbus function code may be faulty ...

Before operating the MS300 series products, please read and pay attention to the relevant safety information to ensure your own safety and product safety. When operating the wiring and installing the inverter, it is necessary to confirm that the power supply is closed. After blocking the communication power supply, the inverter POWER indicator (located in ...

Delta's thermostat is a commonly used temperature control device, which can adjust the temperature according to the user's needs, and then achieve the intention of saving energy. The effect and use of Delta thermostats are also very widespread, so let's introduce the effects and uses of Delta thermostats. ...

If the inverter is to run the equipment again after being shelved for more than half a year, the probability of damage may be greatly increased due to many factors such as the placement environment, the service life of the inverter, and the load rate, and the failure usually presents the following problems: ...

1. Each VFD should be cleaned and protected once a quarter. Protecting and cleaning equipment must have specific records and the signature of the person in charge. As long as the management is in place, the task can be completed with quality and quantity; 2. Before cleaning, the power supply must be blocked, and the voltage must be reduced to a safe voltage before starting to work. ...

1. Restore the inverter to factory settings, press the "ENTER" button to enter the parameter setting interface, and press it continuously until it is 00-00 and then stop. Press the number up button to change to 00-02. Press the "ENTER" key again, the panel value will show 0, press the number up key to change it to 9. Press the "ENTER" key, break ...

1. Use a vacuum cleaner with a plastic nozzle to completely clean the inside and outside of the inverter cabinet to ensure that there is no excessive dust around the equipment. 2. Check the ventilation and lighting of the inverter room, and the ventilation equipment can work normally. 3. Check the inverter ...

1. When the Delta inverter breaks down in the future, it is best not to hand it over to someone who has no experience in repairing the inverter to repair the inverter, otherwise it may get worse and worse. Sometimes it's about to fuse, be sure to check whether there is a problem with the module, some electricians have not experienced it, and immediately install a good fast melt (definitely not ...

The low-voltage fuse cannot be used as an overload maintenance for the motor. It is necessary that the additional voltage of the fuse is greater than or equal to the operating voltage of the distribution line. The additional current of the fuse must be greater than or equal to the additional current of the melt. ...

PLC progressive scanning standard work preparation. Abundant programming language: instruction statements; ladder diagram; SFC。 Abundant instruction statements: 45 instruction varieties, including 28 root instructions and 17 usage instructions. 350 step law capacity. uS-level root directives ...

The role of the "communication input reactor" of the inverter input device is mainly to improve the power factor of the communication power supply on the communication side of the input side; It is useful to eliminate the higher harmonics on the input side to avoid damage to other electrical equipment caused by voltage distortion; Eliminate the three-phase AC power phase ...

First, the maintenance of the inverter must first check whether the sound in the operation of the motor has changed abnormally, 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. Learn more about Delta's inverter ...

Delta was established in 1971 to provide power supply and heat dissipation treatment programs for the world. Over the past 20 years, Delta's development in Chinese mainland has become increasingly deep-rooted, and its business operations cover development, production, sales and service. With innovative skills, we will continue to strengthen engineering research and development equipment and sophisticated testing ...

Generally, household appliances use a single-phase asynchronous motor, which relies on capacitance or resistance to split the phase. Motors are often in a short-term repetitive state (on/off) during operation, such as air conditioners, refrigerators, etc. This will inevitably lead to frequent starting, high noise, short motor life, poor temperature stability and energy consumption.

The ubiquity of AC drives brings significant energy savings to industrial applications. However, the high-frequency switching signal generated by the inverter is easy to form electromagnetic disturbance, which affects the power quality. It is especially significant in occupations with large loads such as lifting and elevators. At this time, the inverter ...

Inverter acceleration form and deceleration form selection, also known as acceleration and deceleration curve selection. Generally, there are several forms of inverter, such as linear, S-shaped, semi-S-shaped, etc., and the characteristics and uses of each form are as follows: 1. Linear form This form makes the inverter's ...

It must be placed in a ventilated, dust-free, dry place. The ambient temperature of the storage location must be in the range of -10°C to +40°C The relative humidity of the storage location must be in the range of 0% to 90% and be free of dew. ...

The thermometer method and resistance method can be used to measure the temperature rise of each part of the reducer. 1) Thermometer method: This is the easiest way to measure the temperature directly, and it is commonly measured by an alcohol thermometer. When measuring, the thermometer can be placed close to the ...

The capacity selection of the inverter is based on the rated power of the motor Myth: The capacity selection of the inverter is based on the rated power of the motor Compared with the electric motor, the price of the inverter governor is more expensive, so it is important to ensure that the ...
