This document is a programming supplement for a Microprocessor Control used in Roll Heated Flatwork Finishers. It provides detailed instructions for configuring and managing various operational parameters of the finisher, ensuring optimal performance and user control.
The Microprocessor Control is the central intelligence for the Roll Heated Flatwork Finisher, enabling precise management of its heating and operational characteristics. Its primary function is to allow users and technicians to program specific settings that dictate how the finisher operates, including temperature control, speed, and automatic shutdown features. This control system ensures that the finisher can be tailored to meet diverse laundry processing needs, from delicate items requiring lower temperatures to heavy-duty fabrics needing higher heat and specific speeds. The control panel, depicted in Figure 1, serves as the interface for both monitoring and programming these parameters. It features a temperature display (5) and a speed display (6), along with various keypads for input: Stop (1), Increase Preset Temperature (2), Decrease Preset Temperature (3), Display Preset Temperature (4), Increase Ironing Speed (7), Decrease Ironing Speed (8), and Start (9). This intuitive layout facilitates easy navigation and adjustment of settings.
The programming mode is a critical aspect of the control's functionality, allowing for in-depth customization. To access this mode, users must simultaneously press the START and STOP keypads while turning the finisher on. Once in programming mode, the temperature display shows the value of the parameter to be set, while the speed display identifies the parameter with a letter or number. The blinking temperature display indicates that the value is ready for modification. Parameters can then be adjusted using the Increase Preset Temperature (+) or Decrease Preset Temperature (-) keypads and confirmed with the Display Preset Temperature (SET) keypad. Exiting the programming mode is achieved by pressing the STOP keypad or by turning the finisher off and on.
One of the fundamental programmable options is the Temperature Measurement Unit. This allows the owner to choose between Fahrenheit (°F) and Celsius (°C) for temperature display, catering to regional preferences and standards. The default setting is Celsius. This ensures that operators can work with familiar units, reducing potential errors and improving ease of use.
The Maximum Preset Temperature parameter defines the highest temperature a user can select for operation. This feature acts as a safety and operational boundary, preventing accidental overheating or misuse. The default maximum is 180°C (356°F), with a programmable range from 1°C to 180°C (34°F to 356°F). This flexibility allows the finisher to handle a wide array of fabrics while maintaining control over extreme temperatures.
The Operating Temperature setting allows the owner to establish the desired working temperature for the finisher. This is a crucial parameter for achieving optimal drying and finishing results for different types of linen. The default operating temperature is 130°C (266°F), with the same programmable range as the maximum preset temperature. Adjusting this setting enables precise control over the finishing process, ensuring quality and efficiency.
Temperature Regulation Hysteresis (Variance) is another key programmable option. This setting defines the acceptable temperature fluctuation around the set operating temperature. A hysteresis value prevents the heating elements from constantly cycling on and off, which can prolong their lifespan and maintain more stable heat. The default variance is 2°C, with a range of 1-5°C (2-9°F). For electrical heating systems with two resistor groups, this hysteresis primarily affects the second group, while the first is controlled in a standard manner. This nuanced control helps in maintaining consistent heat distribution and energy efficiency.
The Temperature for Automatic Shut-down is a safety feature that sets the maximum temperature at which the machine will automatically power down. This prevents damage to the machine or potential hazards in case of overheating. The default shutdown temperature is 80°C (176°F), with a programmable range from 1°C to 180°C (34°F to 356°F). This ensures that the finisher will safely power off if it reaches an unsafe temperature, protecting both the equipment and the environment.
The Heating Type parameter allows the owner to specify whether the finisher uses electrical heating or gas/steam heating. This setting is critical for the control system to correctly manage the heating elements and associated processes. The default setting is "EL" for Electrical, with "GAS" for Gas/Steam as an alternative. This configuration ensures that the control system operates in harmony with the installed heating mechanism, optimizing energy use and performance.
Finally, the Number of Resistor Groups Installed is a parameter specifically for electrically heated finishers. It allows the owner to set the number of heating resistor groups present in the machine. This setting is only displayed if "EL" (Electrical) was selected as the heating type. The default value is 2, with available options of 1 or 2. This parameter enables the control system to accurately distribute power and manage the heating process across the available resistor groups, contributing to efficient and uniform heating.
The Microprocessor Control is designed for ease of use, allowing operators to quickly understand and manage the finisher's settings. The clear digital displays for temperature and speed provide immediate feedback on the machine's status. The dedicated keypads for increasing, decreasing, and setting parameters simplify the adjustment process, making it accessible even for users with limited technical experience. The ability to switch between Celsius and Fahrenheit ensures that the machine can be comfortably operated in various regions without the need for manual conversions.
The programming mode, while requiring a specific entry sequence, is structured logically, guiding the user through each parameter. The blinking display for values ready to be changed provides a clear visual cue, reducing confusion. The "SET" keypad acts as a confirmation and progression tool, ensuring that changes are intentionally applied before moving to the next setting. This sequential approach minimizes the risk of accidental parameter changes.
The inclusion of a maximum preset temperature and an automatic shutdown temperature enhances operational safety. Operators can confidently set desired temperatures within a safe range, knowing that the machine has built-in safeguards against overheating. The hysteresis setting further refines temperature control, leading to more consistent finishing results and potentially reducing energy consumption by preventing rapid on-off cycling of heating elements.
The flexibility to define the heating type (electrical or gas/steam) means that the same control system can be adapted to different finisher models and energy sources, simplifying maintenance and training across a range of equipment. For electrical models, specifying the number of resistor groups allows for optimized power management and heating efficiency.
The programming supplement itself serves as a crucial maintenance tool, providing comprehensive instructions for configuring the control system. By detailing each programmable option and its adjustment procedure, the manual empowers technicians and owners to troubleshoot and fine-tune the finisher's performance. The "Keep These Instructions for Future Reference" note emphasizes the importance of retaining this document, especially if the machine changes ownership, ensuring that future users have access to essential programming information.
A significant maintenance feature is the ability to Resetting Parameters to standard default values. If the finisher's performance degrades due to incorrect settings or if a complete reset is required, pressing the START and SET keypads simultaneously will restore all parameters to their factory defaults. The display showing "Pr" confirms the command. This function is invaluable for restoring the machine to a known good state, simplifying troubleshooting, and ensuring consistent operation across multiple units of the same model. The table of default parameter values provided in the manual is a quick reference for these standard settings, aiding in verification after a reset.
The clear, step-by-step instructions for entering and exiting programming mode, along with the detailed descriptions of each parameter, reduce the complexity of maintenance tasks. Technicians can efficiently navigate the control system, make necessary adjustments, and verify settings without extensive trial and error. This structured approach to programming and resetting parameters contributes to the longevity and reliable operation of the Roll Heated Flatwork Finisher. The manual's emphasis on retaining the document for future reference underscores its role as a vital resource for ongoing maintenance and operational support.
