Maintenance and Preventative Maintenance
Air Pressure Recommendations:
Approximately 5.5 bar (80 psi) is recommended for most models. 4.1 bar (60 psi) is
recommended for: Micro Blender, 140R, 240R and 440R. The coalescing filter is a
final attempt to dry the air to protect the valves and solenoids from moisture
contamination. Check for correct air pressure, tight fittings, and no damaged or
crimped air lines.
NOTE: Micro Blenders should be set to 4.1 bar (60 psi). The Vertical
Valves used in removable hoppers on Micro Blenders are more
accurate at the lower 4.1 bar (60 psi) pressure setting.
Do NOT use lubricated air. Lubricated air can cause air
cylinders and air solenoids to stick, jam or malfunction.
Air provided to the blender should be clean and dry.
Level Sensor Adjustment
Adjusting sensor sensitivity:
1. The adjustment screw is located at the rear of the sensor and is a ten-turn pot.
You will need a very small regular screwdriver to adjust it.
2. Turn the adjustment screw clockwise until the LED turns ON.
3. Turn the adjustment screw counter-clockwise until the LED turns OFF.
4. Continue turning for one full revolution after the LED turns off.
5. When material is present in front of the sensor, the LED should turn on.
6. Additional adjustments may be necessary as a result of material dust or static.
Sensor position on 200 and 400 series models only:
The sensor should protrude into the mix chamber about 1/4 inch past
the inside surface of the stainless mounting plate. If it does not
protrude far enough, it will sense the mounting plate itself. If it
protrudes too far, it will sense the mix blade.
Weigh Bin Dump Valve
The weigh bin dump valve should be adjusted to close softly. A needle valve is
installed on or behind the solenoid bank or located on the weigh bin air cylinder.
Adjust for a soft close. Hard closure of the weigh bin dump valve over time can
cause damage to the weigh bin. Check for wear at the hinge points. The Dump Flap
should overlap the forward edge enough to prevent dribble when closed, even when
closed against pellets. Space at the rear of the flap should allow for static build up of
pellets on the rear edge of the dump flap without interfering with the closing of the
flap.
