PQR10A type magnetic disk control panning control circuit

Description: The system is managed by the master controller LKl-12/90 and a magnetic disk control unit PQR10A, which includes a control circuit. The cam control device SA is responsible for contact closure, as indicated in Table 8-5. The main electrical components include the osi power switch, os2 control circuit switch, and control reversing contactors KM3 and KM2, which are equipped with mechanical and electrical interlocks. The KA zero pressure relay provides motor starting voltage protection and zero pressure safety features. The KI- and KI2 overcurrent relays protect the motor from overload and short circuit conditions, while limit switches are integrated into the lifting mechanism. The YA brake contactor initiates mechanical braking for the motor. The reverse contactors KM5 and KMs, along with the acceleration contacts KM7 to KM1, manage the motor's speed and control access to short circuits in the electric rotor. The master controller SA issues commands for various operational modes or braking. The system operates with 13 locations: it can rise or decline through 6 gears, including a zero gear. The configuration includes 12 pairs of contacts that close in different gear scenarios, as detailed in the referenced table.

The described system operates as a sophisticated control mechanism for motor management, utilizing a combination of relays, contactors, and control circuits to ensure safe and efficient operation. The master controller LKl-12/90 serves as the central processing unit, coordinating the actions of various components based on input signals and operational requirements.

The magnetic disk control unit PQR10A plays a crucial role in the control circuit, managing the execution of commands issued by the master controller. The cam control device SA facilitates the physical connection and disconnection of circuits, allowing for precise control over motor operations.

Key components such as the osi power switch and os2 control circuit switch are essential for initiating and regulating power flow to the system. The control reversing contactors KM3 and KM2 are designed to reverse the direction of the motor, with built-in interlocks that prevent accidental operation, enhancing safety during use.

The KA zero pressure relay is critical for ensuring that the motor does not start under unsafe conditions, providing voltage protection and preventing operation when pressure levels are not adequate. The overcurrent relays KI- and KI2 serve to protect the motor from damage due to excessive current, effectively safeguarding against overload and short circuits.

Limit switches integrated into the lifting mechanism provide feedback on the position of the motor, ensuring that operations are halted when maximum or minimum positions are reached. The YA brake contactor is responsible for engaging mechanical brakes, facilitating safe stopping of the motor during operation.

The reverse contactors KM5 and KMs, along with the acceleration contacts KM7 to KM1, enable precise control over motor speed and direction, allowing for smooth transitions between operational states. The master controller SA is integral to managing these functions, issuing commands based on the desired operational mode, whether it be lifting, lowering, or braking.

Overall, the system is designed to operate efficiently across multiple gears, with 13 distinct locations available for operation. The configuration of 12 pairs of contacts allows for flexibility in operational modes, ensuring that the system can adapt to various requirements as outlined in the referenced table. This comprehensive control architecture ensures that the motor operates safely and effectively under a range of conditions.
