9.1.
The Metra Separator switching on:
1.
Set the 'Feed Gate Control' handle to the '0' position.
2. Fill the hopper with grain to the specified level, not less than minimal level.
3. Reset the 'EMERGENCY STOP' button.
4. Move the 'POWER' knob to 'ON'. The 'POWER' indicator will light up if it is under voltage.
5. Set the 'POWER' knob to the middle position.
6. Turn on the frequency converter power, by setting the 'DIRECTION OF ROTATION' switcher in the separation or
reverse mode. Together with the indicator lights, the impeller motor will begin to smoothly gain speed reaching
predetermined speed.
7.
Turn off the Metra Separator in reverse order.
8. Pressing the 'EMERGENCY STOP' button carries out emergency shutdown of the Metra Separator.
Press the 'EMERGENCY STOP' button only in cases of emergency!
9.2. Operating modes settings:
Preliminary cleaning mode
1.
Switch on the Metra Separator as described above.
2. Fill the hopper with material. Ensure continuous supply of the material to the hopper. During operation the user must
control the amount of the material in the hopper - it must be filled to at least 75% of its volume.
3. Set the baffles in upward position, so they are in '0' position.
4. Turn the 'Feed Gate Control' handle to open position. Adjust the 'Speed' knob to the maximum possible value, so the
grain (or other clean material) is not coming out with the light impurities removal.
5. If the Metra Separator is equipped with CDC (Cyclone Dust Collector), make sure that all connections are tight with the
main Metra Separator. Make sure that the gate duct is blocked. Restriction or partial overlapping of the CDC output
tray is not allowed, as this may lead to malfunction of the Metra Separator.
In this mode, when the Metra Separator is properly adjusted, it's able to remove 30% to 60% of the original waste material,
depending on the quality of the grain. When the Metra Separator is operating in this mode, refined grain will be fed from
all trays.
Note that when the material is very dirty, you might need to clean in several stages: first to separate good grains from the
2nd − 3rd trays, having dropped the rest of the material from the 4th − 6th trays into a common storing hopper, and then
clean and grade the second time the grains from the 4th − 6th trays.
Precise grading mode
1.
Switch ON the Metra Separator as described above.
2. Fill the hopper with material. Ensure a continuous supply of the material to the hopper. During operation the user must
control the amount of the material in the hopper - it must be filled to at least 75% of its volume.
3. Set the baffles in upward position, so they are in '0' position.
4. Turn the 'Feed Gate Control' handle to a position of '0.5-1'.
5. Adjust the 'Speed' knob so to receive clean grain in the 2nd-4th trays/outputs.
