The VLT® LCP Remote Mounting Kit is an accessory designed to facilitate the remote installation of VLT® Control Panels, specifically LCP 11, LCP 12, and LCP 21 types. This kit allows the control panel to be mounted separately from the main drive unit, offering greater flexibility in system design and user interface placement. The primary function of this kit is to enable the control panel to be positioned in a more accessible or convenient location for operators, enhancing usability and operational efficiency, especially in environments where the drive itself might be in a less accessible or hazardous area.

Function Description

The core function of the VLT® LCP Remote Mounting Kit is to provide a secure and robust housing for the VLT® Control Panel when it is installed away from the drive. It achieves this by offering a panel-mount solution that integrates the control panel into an enclosure or cabinet door. The kit includes essential components that ensure both mechanical stability and environmental protection for the remotely mounted LCP.

The mounting process begins with the preparation of the LCP itself. A sealing gasket is applied to the LCP, which is crucial for maintaining the IP55 rating of the remote mounting. This gasket creates a tight seal between the LCP and the mounting surface, preventing the ingress of dust and water, thus protecting the sensitive electronics of the control panel from environmental factors. The IP55 rating signifies that the mounted panel is protected against dust ingress sufficient to prevent interference with the operation of the equipment and against low-pressure jets of water from all directions. This level of protection is vital for industrial environments where dust, splashes, or wash-downs are common.

Once the LCP is prepared with the gasket, it is integrated into a pre-cut opening in a panel or enclosure door. The kit provides precise dimensions for this cut-out, ensuring a snug and accurate fit. The LCP is then secured from the backside of the panel using a mounting bracket. This bracket slides into place and is fastened with screws, effectively clamping the LCP to the panel. This method of mounting ensures that the LCP is firmly held in position, resisting vibrations and accidental dislodgement, which is critical for reliable operation in industrial settings.

A key functional aspect of the remote mounting kit is the provision of a communication cable. This 3-meter cable connects the remotely mounted LCP to the VLT® drive. The cable facilitates the exchange of data and control signals between the LCP and the drive, allowing operators to monitor drive status, adjust parameters, and issue commands from the remote location. The connection of this cable to the LCP is made secure using thread-cutting screws, which ensure a robust electrical and mechanical connection. The specified tightening torque for these screws is 1.3 Nm, highlighting the importance of a precise and secure connection to prevent signal loss or intermittent operation.

In essence, the kit transforms the LCP from a drive-integrated component into a standalone human-machine interface (HMI) that can be positioned for optimal user interaction, while maintaining the necessary environmental protection and communication integrity with the drive.

Usage Features

The VLT® LCP Remote Mounting Kit significantly enhances the usability of VLT® drives by offering several key usage features:

• Flexible Placement: The most prominent usage feature is the ability to place the LCP in a location that is most convenient and safe for the operator. This is particularly beneficial when the drive itself is installed in a cabinet, on a machine, or in an area that is difficult to access, exposed to harsh conditions, or requires specialized safety protocols. For example, the drive might be located deep within a machine enclosure, while the LCP can be mounted on the machine's exterior for easy access.
• Improved Ergonomics and Accessibility: By bringing the control panel closer to the operator, the kit improves ergonomics. Operators can interact with the drive parameters and status displays without needing to open cabinet doors or reach into awkward spaces. This reduces physical strain and improves the speed and efficiency of operations, troubleshooting, and maintenance tasks.
• Enhanced Safety: Remote mounting contributes to operator safety. If the drive is in an area with high voltage, moving parts, or extreme temperatures, mounting the LCP remotely allows operators to interact with the drive from a safe distance, minimizing exposure to potential hazards. The IP55 rating of the remote mounting also ensures that the LCP itself is protected, preventing electrical hazards from environmental ingress.
• Centralized Control: In systems with multiple drives, remote mounting can facilitate a more centralized control approach. LCPs from several drives could potentially be grouped together on a single control panel, offering a consolidated interface for monitoring and control, though each LCP would still connect to its respective drive.
• Clear Visual Feedback: The LCP's display and buttons remain fully functional when remotely mounted, providing clear visual feedback on drive status, alarms, and parameter settings. This ensures that operators have all the necessary information at their fingertips for effective control and monitoring.
• Robust Construction: The components of the kit, including the mounting bracket and screws, are designed for industrial use, ensuring durability and long-term reliability in demanding environments. The secure fastening mechanisms prevent the LCP from becoming loose over time due to vibrations or mechanical stress.
• Standardized Interface: Despite being remotely mounted, the LCP retains its familiar interface and functionality, meaning operators do not need to learn new control methods. This consistency reduces training requirements and potential for operational errors.
• Quick Installation: The kit is designed for straightforward installation, with clear instructions and all necessary hardware provided. This allows for quick setup and minimal downtime during installation or system modifications.

Maintenance Features

While the VLT® LCP Remote Mounting Kit itself requires minimal maintenance, its design and components contribute to the overall maintainability of the drive system and the LCP:

• Environmental Protection for LCP: The IP55 rating, achieved through the sealing gasket and secure mounting, is a key maintenance feature. It significantly reduces the need for cleaning or repair of the LCP due to dust accumulation or water damage. By protecting the internal electronics, it extends the lifespan of the LCP and reduces the likelihood of premature failure, thereby minimizing maintenance interventions.
• Easy Access for Troubleshooting: In the event of a drive fault or an issue requiring parameter adjustment, the remotely mounted LCP provides immediate and safe access to the drive's interface. This allows maintenance personnel to quickly diagnose problems, view error codes, and make necessary adjustments without having to access the drive's physical location, which might be in a confined or hazardous space. This speeds up troubleshooting and reduces mean time to repair (MTTR).
• Simplified LCP Replacement: Should the LCP itself need to be replaced (e.g., due to damage or upgrade), the remote mounting design simplifies this process. The LCP can be easily detached from the mounting bracket and the communication cable disconnected, allowing for quick swap-out without disturbing the drive unit or other components within the main enclosure. The standardized cut-out dimensions ensure that a new LCP will fit perfectly.
• Cable Management: The provision of a dedicated 3-meter cable with secure connections aids in organized cable management. Proper cable routing and secure fastening prevent wear and tear on the cable, reducing the risk of intermittent connections or complete communication loss, which would otherwise require troubleshooting and repair. The thread-cutting screws ensure a durable connection that is less prone to loosening over time.
• Robust Mechanical Fastening: The mounting bracket and screws provide a secure mechanical connection that is resistant to vibrations and impacts common in industrial settings. This reduces the need for periodic re-tightening or repair of the mounting hardware, contributing to a lower overall maintenance burden.
• Visual Inspection: The remote mounting allows for easy visual inspection of the LCP's condition, including its display and buttons, as well as the integrity of the panel seal. Any signs of wear, damage, or ingress can be quickly identified and addressed before they lead to more significant issues.
• Component Durability: The materials used for the kit components are selected for their durability and resistance to typical industrial conditions, ensuring that the mounting solution itself is robust and requires minimal maintenance throughout its operational life.

In summary, the VLT® LCP Remote Mounting Kit is a practical and essential accessory that extends the functionality and usability of VLT® Control Panels. It provides a secure, environmentally protected, and ergonomically superior solution for operating and monitoring VLT® drives, ultimately contributing to safer, more efficient, and more maintainable industrial automation systems.
