Ingersoll Rand VSD fault code is the variable speed drive. It measures the DC pressure on the bus in the drive device. If the voltage exceeds 785vdc, it will give an alarm of VSD fault 0. This alarm is issued regardless of whether the motor is running or not
this kind of fault is an instantaneous "no more than" over-current condition. Setting and quick response are part of the driving parameter setting, which is pre programmed. Two blue current transformers are installed on the U and V motor wires of T2 drive, and three current transformers are installed on the U, V and W wires of T1 drive. These transformers continuously monitor the output current of variable speed drive. If the output current exceeds the preset limit value, the alarm will start
it should be confirmed that the supply voltage is within the specified range and the voltage is stable, so as to avoid excessive correction of motor speed when the driving device responds to voltage fluctuation
check all internal connection points for signs of motor phase arcing, current transformer failure or motor wire chafing
confirm that after removing the heat dissipation window at the end of the motor, the motor can be driven to do mechanical movement by hand. When the rotor passes through the winding pole of the motor stator, the rotation will look strange
check the cable wiring of Hall effect sensor and Px4 contact on the control board, loose wiring or poor wiring may cause the drive device to receive abnormal information, which may cause the motor to accelerate too fast, resulting in over-current
check the motor current value in maintenance menu 3 and measure the motor wire with current clamp meter to confirm that the current transformer (CT) does not exceed the standard. The current value in maintenance menu 3 should be consistent with the reading of the ammeter. If not, the current transformer may be faulty
if the problem is not solved, disconnect the motor wires u, V and W from the terminal box of the variable speed drive, and then start the equipment. If alarm 44 appears after re energizing, reset alarm 44 and try to start the motor again

A two-Rome notes issued by the People's Bank of legal tender, original printing by 1953 but only removed from the original Arabic reservations Rome crown, a second series yuan.
China issued two notes at a Rome in the world history of issuing banknotes unique: the first countries in the world have also notes a crown of Rome and Arabic numbers, but a vote on the 1st of non-repetition. Only China, the paper points with the Rome crown coins only words, no Arabic. The second, more unusual is a prevailing at the existing two Roman crown, Rome has three crowns, but the telephone, Mrs. coupons only three points of the Rome crown without two of the Rome crown. Third, the paper has been widely used coin, consumption, few of the world graally, especially Rome two notes at a minimum distribution of the coupons. Thus a two notes at the Rome crown at home and abroad, a community in the Wonder notes, even as the types of banknotes, a collector by domestic and foreign concerns.
With the April 1, 2007 - People's Bank of China announced at the world's smallest coin denomination banknotes from circulation, no paper, the investment value of coins, and the collection has been incalculable value. Especially in recent years, "Coin collectors hot" trend, in the collections of the two Arabic numerals, a Roman crown at the main contents of the notes, "the truck" collection, which has been hot, with its unique investment and the appreciation of small fast Popularization (women and children all know, cute love), the whole set difficult (crown , variety and thorough destruction of consumption), advantages, collectors and the general public has been widely accepted.
In order to meet the needs of the collections, we in the departments under the strong support and assistance, especially Featured two notes Rome late VI IX X XI-40 crown, even, in the country and 80,000 limited edition to meet the collection needs of the market.
the new banknote is printed with the torch figure in the hands of the statue of liberty and the English phrase "we the people" quoted from the constitution of the United States. It has a very light orange, yellow and red background and has a variety of anti-counterfeiting features that are easy to identify<
Treasury officials said at a news conference that the new version of the $50 bill will be more difficult to forge and easier to verify, for example, the use of complex colors makes it more difficult to forge. The new version of the $50 banknote retains three main anti-counterfeiting designs, namely watermark, anti-counterfeiting strip and color changing ink, which were adopted since the 1990s, so as to facilitate ordinary consumers to distinguish the authenticity of banknotes
it is reported that the new version of the $50 note will be officially issued at the end of September or early October this year. In recent years, the US government has taken a series of currency renewal measures to crack down on counterfeit banknotes. In October last year, a new version of the $20 banknote officially entered circulation. The US government also plans to launch a new version of the $100 banknote. Relevant parties are still considering redesigning the $5 and $10 banknotes. With the development of digital technology, counterfeit banknotes are more lifelike, easier to manufacture and cheaper. Due to the widest circulation range of US dollar, it often becomes the first choice of counterfeiters. According to the data provided by the U.S. government, the face value of the counterfeit U.S. dollar notes that were not in circulation in the U.S. fiscal year 2003 was 63 million U.S. dollars, and the face value of the counterfeit U.S. dollar notes that have been in circulation was 38 million U.S. dollars. At present, about 42% of the counterfeit money in the US market comes from outside the US. The U.S. government has decided to update the design of dollar bills every seven to 10 years in order to be ahead of counterfeiters in technology
the US dollar in circulation now is the Federal Reserve note issued after 1945. The currency symbol formulated by the international organization for standardization is VSD, and the carry of the secondary currency is 100 cents, which is equal to 1 US dollar. The main currency above yuan is paper currency, and the subsidiary currency below yuan is metal currency. There are paper and coins of 1 yuan denomination. At present, there are 7 kinds of banknotes with denominations of 1 yuan, 2 yuan, 5 yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan. Most Americans don't like to use 2 yuan banknotes, so they have a small circulation and become hard to find for collectors
since 1996, the same watermark as the face figure has been added to the right side of each denomination dollar, and the face figure has been enlarged. All the parts of the face figure have been printed with engraving gravure, and the miniature English of "United States of America" has been added around the face figure, which greatly improves the anti-counterfeiting ability. Americans are very familiar with the figure on the dollar, which has become an important feature to distinguish the denomination and identify the true and false. There are three Unifications in the appearance of the US dollar: first, the size of each denomination is 156 mm × 66 mm; Second, there is no color separation for each denomination. The main color on the front is black, and the main color on the back is green; Third, the fabric structure and thickness of each denomination banknote paper are basically uniform. They are tough and stiff, and generally do not fluff when used
the anti-counterfeiting technology of US dollar is constantly improving, and the main anti-counterfeiting measures are as follows: 1. Anti counterfeiting paper. Dollar paper is made of special fiber with good stiffness and wear resistance, and fine red and blue fibers are mixed into the paper. Engraving gravure printing. For example, the characters and denominations on the positive side of the US dollar are printed in gravure, which makes the pictures and texts on the face of the bill bulge and makes the hand feel concave and convex. 3. Complicated and delicate treasury seal. The treasury seal is printed on the right side of the front of all U.S. banknotes. The seal is round, emerald green, with equal teeth on the periphery. The center of the circle is a shield. The shield is divided into two parts by an inverted "V". The upper part is the balance, the lower part is a key, and the keyhole has a "t" shaped secret mark. The design is fine and complex, but the impression is clear and uninterrupted. 4 with microfilm safety line. The left side of the Federal Reserve Bank seal is embedded with a safety line with microfilm. Taking the 1990 100 yuan bond as an example, the words "usa100" appear many times from top to bottom along the vertical direction of the surface of the safety line. This can be seen from the perspective of light or facing light. 5 microfilm. On the edge of the portrait on the front of the US dollar, there is a repeated miniature letter: "the United States of America". The text is very small and can be seen with a magnifying glass. After 1996, the same watermark as the face portrait was added. In the note paper on the right side of the face, the same watermark as the face portrait can be seen facing the light
in addition to the above, there are many specific anti-counterfeiting measures in the anti-counterfeiting design of US dollar bills, which will not be explained one by one.
