HARDWARE MAINTENANCE
AIR PRESSURE
Set AIR PRESSURE to about 80 PSI for best accuracy. However, lower pressures
will work. If you plant air fluctuates, set the regulator to the low end so that the
dispense valves always see a consistent pressure. Lubricated air is NOT
recommended. Micro Blenders should be set to 40 PSI (2.7 bar). Vertical Valves
used in removable hoppers on Micro Blenders, and 100 and 200 series blenders, are
more accurate at 60 PSI pressure setting.
LEVEL SENSOR
Sensor position; 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.
Adjusting sensor sensitivity:
1. The adjustment screw is located at the rear of the sensor. It may be protected
by a small plastic screw like cover. You will need a very small screwdriver to
adjust it.
2. Fill the mix chamber until the sensor is about 3/4 covered.
3. Turn screw counter-clockwise until the LED goes OFF.
4. Then turn clockwise until the LED just goes ON.
5. Empty the chamber and check to be sure the sensor LED does not go on
when the mix blade passes near it.
WEIGH BIN DUMP VALVE
The WEIGH BIN DUMP VALVE should be adjusted to close softly. A needle valve is
installed next to the quick disconnect so that air flow to the flap air cylinder may be
restricted. Adjust as required for a soft close.
SLIDE VALVES
Slide valves must move very freely. If they seem to jam slightly as they reach the full
extended position (closed), this may be due to the air cylinder mount being slightly
bent. If someone has pulled down or pushed up on the air cylinder, they may have
bent the cylinder mount. You can correct this by pressing up or down on the cylinder
as required to correct the problem.
If you process very hard pellets (polycarbonate and glass filled resins), your slide
gate dispense valves may stick closed occasionally. We provide spacers that limit the
full stoke of the air cylinder. This stops the slide from going any further then the just
closed position and prevents jamming. Call us for information.
INTERNAL MIX MOTOR and AUGER FEEDER FUSES
The MIX MOTOR timed power source and the AUGER FEEDER OUTLETS are
driven by internal solid state plug-in relays. A small 5 amp glass fuse is located to
the right of each relay. A spare fuse is also located on the board if replacement is
necessary.
