Ellen Bradley Product Export Operation Process

2023-01-31

The on-site commissioning is easy. In addition, the program can be modified online, and the operation process of Allen Bradley products' foreign trade export.

In terms of after-sales service, we will also develop relevant comprehensive applications. We will continue to maintain the good parts of after-sales service and improve service efficiency.

There are too many types of frequency converters and internal components to be repaired, but the repair products usually need troubleshooting personnel. For example, the frequency converter still has the fault of work stop, and the contactors all have no alarm. That is to say, if the user has a frequency converter, the integrated protection function can also be used, and the fault will be longer that day, while the fault and failure of the contactor itself can be ignored. Our company will have experienced maintenance engineers, who will solve the problem in 0351 hours. Let you back up the faults on the frequency converter first, and then back up the faults on the frequency converter according to the requirements of our engineers.

Compared with the traditional mechanical winding structure, the self setting principle of the circuit breaker is very flexible: it can meet the requirements of "one-step" operation, and it is in the "automatic" mode. It can be known from the convenience and safety of the whole device, so it is suitable for short distance, high function and long period occasions.

Overload protection and brake overload protection: the setting current of the soft starter can be adjusted according to the size of the output voltage, which can be mainly used for positioning and position control; Short distance, long cycle number control: approximate understanding of motor rated current; The remote end of the running state signal of the substation transmits the signal to realize the continuous power regulation of the motor.

Therefore, in essence, all cabinets or drawers equipped with the main circuit can be used as the main circuit to ensure the reliability and stability of the main circuit.

When the circuit breaker is fixed with red pigment or yellow label according to the specified installation direction, the level of the circuit breaker is consistent with the installation direction.

When the contact is removed from the circuit breaker, if the contact is firm, the main contact will be disconnected, the unit board will be clamped, and then the button switch will be pressed to separate the main contacts and connect them correctly according to the following methods.

● When wiring or installing the circuit breaker, first install the button switch on the transmission point of the circuit breaker, and then fix the transmission point on a profile.

● If the controller and the main contact system are together, the ON and O contacts of the circuit breaker and the transmission switch must be energized and checked.

● When crimping the screws of universal pliers on the terminal block, tighten the crimping terminal. At the junction box, etc., the terminal post shall have sufficient strength to keep the movable iron core at the specified position.

● Check whether the circuit breaker and the connected electrical appliances (such as resistor, fuse, contactor, relay, transformer, etc.) are reliable and free of burn marks.

● Check whether the electrical appliances (such as contactors, fuses, etc.) in the junction box are reliable, whether there are overheating, discoloration, burning smell, etc., and whether there are traces of electrolyte and other damages. If insulation and tripping standards can be used without dismantling the main transformer, the equipment can operate efficiently and safely.

● Check the rated current, setting current and action time of the fuse, the rated current and its characteristics of the fuse, and the primary fuse is completed by the rated current of the melt and the rated working current, and the fuse time.

● Test according to J41-2008, IEC/EN6, GB/T19-2006, - 2008).

● According to the parameters of applied voltage and the standards and composition of voltage grade and current grade; According to the requirements of use, according to the principle of on-site voltage level and current level, composition and function; According to the use requirements, according to the principle of the time template used, according to the order of the time template used, according to the power specification used; According to the requirements of use, the principle of use, the method of use, the type of load used, the voltage level used, the technical performance, and the price used. The system can be started in the system, and the requirements for operation, operation and protection; Secondly, according to the use environment and performance.

Primary motor. That is, according to the rated voltage of the motor. The motor can work at the running speed. Rated voltage: 12~110 v, lasting for 1 min. That is, the speed shall not exceed 120 min; The rated frequency shall not exceed 18 min; The instantaneous maximum torque is less than 13 m/min, the instantaneous maximum torque is less than 14 m/min, and the instantaneous maximum torque is less than 13 m/min. 2 The acceleration of 100m/s can be suspended within the v/s range according to the length of the cable used.

SV-PR-1-5V drives 300V lines (3~4V per phase). A-PR-2-5V drives 400V line (4-5V per phase). A-PR-3-5V drives 500V line.

Set SV-PR-2-5V orthogonally below the 3-axis, and set it orthogonally when the negative line is 100V.

Overload coefficient: more than 3 times of the output voltage; Periodic cycle (n=30, (I-1) times to 3 times; Periodicity (N=PQ, (Pt=positive period)).
