Contrec 515-LP01 Load Computer
The Contrec Load Pro-B Load Controller is designed for various applications in single-arm loading systems. This user-friendly 5-key controller features Dual Stage or Digital Valve Control, ensuring the precise and reliable delivery of preset amounts of liquid products. It accepts frequency flow input from volumetric or mass flowmeters and can also process a quadrature signal for ISO 6551 level B pulse security. Additionally, it can incorporate temperature, pressure, and density inputs for accurate volume correction. The controller can be set to load based on either volume or mass preset quantities.
The Batch Controller prompts users for a valid User Access ID (ID-Tag or Pin-Number) and gathers task-specific information before starting the delivery process. This Access ID and the relevant data are stored as part of the transaction record, which can be accessed by external databases. The controller includes a pump demand output and emergency stop inputs to ensure safe and controlled delivery of products in single-arm loading applications.
A series of start sequences guarantees that loading or off-loading is performed safely and accurately. It allows for custom transaction information, compartment numbers, preset values, and permissive inputs to be manually entered or confirmed before the loading or off-loading begins.
