Maguire Weigh Scale Blender WSB-441

Check that all load cell components are in place

Inspect load cell for physical damage

Is the load cell zeroed correctly?

Is the load cell calibrated for full weight?

Locate the adjustment screw at the rear of the sensor

Use a very small regular screwdriver for adjustment

Turn the adjustment screw clockwise until the LED turns ON

Turn the adjustment screw counter-clockwise until the LED turns OFF

Continue turning counter-clockwise for one full revolution after the LED turns OFF

Does the LED turn on when material is present in front of the sensor?

Note any additional adjustments made due to material dust or static

Sensor Position Adjustment (200 and 400 Series Models Only)

Test slide valve movement during LOTO without air pressure

Do slide valves open and close freely, quickly, and completely?

Check for wear on the slide valve guide rods

Check cylinder clevis adjustment for correct closing of the valve

Does the valve close just enough to block the hole, but no further?

Check the clevis pin connecting the air cylinder for wear

Inspect mix blades for damage or wear

Enter the current air pressure reading

Is the air pressure approximately 5.5 bar (80 psi) for most models?

Is the air pressure 4.1 bar (60 psi) for Micro Blender, 140R, 240R, and 440R?

Is the coalescing filter functioning properly?

Check for the following issues in the air system

Verify the load cell cable is plugged into the controller

Ensure the weigh bin is resting freely on the load cells

Check the air line to the weigh bin’s dump valve is connected

Ensure load cells and bin are not jammed

Does a light touch on the bin cause the display to change and return to its original value (±1 gram)?
