Unist Fluid Controller
Model SPR-2000 Sproller
The SPR-2000™ programmable fluid controller is designed to precisely control lubricant supplied to Unist Uni-Rollers®, Unist spray nozzles, and in-die lubrication points.
SPR-2000™ Programmable Fluid Controller An optional press control interface takes this functionality one step further, allowing standard press controls to interface directly with the SPR-2000™ and change the setup based on the currently running job.
The SPR-2000™ is also designed to monitor critical parameters such as fluid level, fluid pressure, and flow (optional sensors may be required).
It can alert the operator with an audible alarm, a red LED, and even an external alarm relay which can be wired directly to a press control.
If unauthorized access to the system settings is an issue, the system can be configured with a custom 4-digit access code.
This allows the operator to monitor alarms and recall saved setups, but not modify system settings or create new setups. At the heart of the SPR-2000™ is a proprietary electronic controller. The controller intermittently actuates a bank of valves to dispense the required quantity of fluid to the appropriate lube points.
The programmable actuation of the valves is based on an intermittent (rate dependent) input from the line. On stamping presses, this input is typically based on the stroke of the press and comes from a programmable limit switch (PLS) or the press controller. In continuous speed operations such as roll forming, an optional rotation sensor is available which provides one input for each roller revolution on a Uni-Roller® Type S or Mini-Roller™ system. The SPR-2000™ menu-driven software easily guides the user through the process of creating setups (programs) and saving them to memory. The system can save up to 250 different setups so changing to a new job is as simple as pushing a few buttons.
