Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The PFREUNDT WK60 series is a sophisticated weighing system designed for wheel loaders, telescopic handlers, and forklifts, aiming to provide easy, better, and accurate weighing. This operating manual outlines the essential aspects of using, maintaining, and understanding the WK60 scale, ensuring safe and efficient operation.

Function Description

The WK60 scale is primarily designed for dynamic and static weighing of bulk goods and raw materials. It integrates seamlessly into the operation of various loading vehicles, allowing for on-the-go weight measurement. The system's core function is to accurately determine the weight of material in a loading bucket or on lifting forks, providing real-time data to the operator. This is crucial for managing loads, preventing overloading of transport vehicles, and ensuring compliance with national regulations, especially for legal-for-trade applications.

The scale operates by measuring the weight of the load as the lifting arm moves through a defined weighing position. For dynamic weighing, the system captures the weight during the lifting movement, while static weighing involves stopping the lifting arm briefly within the weighing area. The WK60 automatically adds fixed weights to a running total, allowing operators to track the cumulative load. It also supports target weight management, enabling operators to pre-set a desired load amount and monitor the remaining weight to be loaded.

Beyond basic weighing, the WK60 offers a range of advanced functions. It can store and manage master data, including information on customers, materials, delivery locations, and vehicles, streamlining the loading process. The system also supports data transfer via USB sticks or the PFREUNDT Web Portal, facilitating the export of weighing data, master data, and custom weighing cards for external analysis or record-keeping. For enhanced accountability, an alibi memory function stores loads and weighings in a tamper-proof manner, crucial for legal-for-trade operations.

Usage Features

The WK60 scale is designed for user-friendliness, featuring a clear display and intuitive menu navigation. The main page of the weighing program provides a comprehensive overview of the current status, including the gross weight, total weight, and number of completed weighings. Operators can easily access additional information such as accuracy class, approval details, sensor data, and software version directly from the display.

Key usage features include:

• Switching On/Off: The scale is activated by holding the On/Off button for approximately 2 seconds, followed by an automatic start-up process that opens the weighing program.
• Zeroing the Scale: Both dynamic and static zeroing functions are available to ensure accurate measurements. Dynamic zeroing involves moving an empty loading bucket through the weighing position, while static zeroing requires pulling the empty bucket in completely and stopping the lifting arm briefly within the weighing area. The system may prompt for zeroing if the oil temperature deviates significantly or after a certain period of inactivity, sometimes requiring warm-up strokes to optimize hydraulic oil temperature.
• Performing Weighings: For wheel loaders, operators lower the lifting arm, load the bucket, raise it completely, and then move the arm through the weighing position from below. For forklifts, the load is lifted, the mast positioned vertically, and the loaded fork driven through the weighing position. The fixed weight is displayed and added to the total. The system prompts the operator to empty the loading bucket/fork as needed.
• Target Weight Management: Operators can enter a target weight before starting a loading process. The display shows the target weight and the remaining weight, helping to prevent overloading.
• Quitting the Loading Process: The "Loading" application provides options to finalize the loading process, such as printing a weighing slip, saving master data as favorites, or initiating a cash sale.
• Master Data Selection: The system allows operators to select and manage master data (customer, material, vehicle, etc.) from pre-defined lists, which can be searched and filtered.
• Data Transfer: Data can be transferred to external computers using a standard USB stick or via the PFREUNDT Web Portal, which connects through WLAN or a mobile network.
• Additional Applications: The WK60 includes various applications such as "Info" for software and hardware details, "Diagnostics" for error analysis, "Printer" for configuring print functions, "Alibi memory" for tamper-proof load records, "PFREUNDT Apps" for installing/uninstalling functions, "Statistics" for evaluations, "Master data" for managing information, "Login" for user management, "Target weight" for load planning, "Collective ticket" for assigning materials to delivery notes, and "Date-time" for system clock configuration.

Maintenance Features

Maintaining the WK60 scale is straightforward, focusing on regular cleaning and adherence to operational guidelines to ensure longevity and accuracy.

• Cleaning: The WK60 weighing unit and the pPrinter Matrix printer can be cleaned with a damp cloth. The touchscreen should be cleaned with a lint-free cloth (e.g., microfiber or eyeglass lens cleaning cloth) using light circular movements without applying pressure. It is crucial to avoid aggressive or abrasive cleaning agents, as these can damage the unit and touchscreen.
• Regular Inspections: Operators are advised to regularly inspect the scale and all associated components for any signs of damage. Any damaged components should be replaced by PFREUNDT Service to prevent safety hazards and ensure continued accuracy.
• Calibration: For legal-for-trade scales, periodic calibration is mandatory and must be performed in accordance with national regulations. The operating company is responsible for ensuring regular calibration.
• Software Updates: While not explicitly detailed as a user-performed maintenance task, the "PFREUNDT Apps" function suggests the possibility of installing or uninstalling additional functions, implying that software updates or feature management can be part of the system's upkeep.
• Environmental Considerations: The manual emphasizes operating the scale within its permitted temperature range and avoiding environments with potentially explosive atmospheres, aggressive substances, or stray currents/heat. These precautions are essential for the scale's proper functioning and lifespan.

By following these guidelines, operators can ensure the WK60 scale remains a reliable and accurate tool for their weighing needs.
