WARNING:
All wiring to the equipment must be made by the user or pur-
chaser. This includes all interconnections between the equipment
and any Acrison supplied control panel(s) as well as any safety
switch(es) and/or safety interlock(s) either required by law and/or
the electrical standards of the user.
6.
The feeder is factory lubricated and ready for operation, although lubrication verification is
recommended. Please refer to Section 6.0 (Maintenance), paragraphs 6.1, 6.2, 6.3 and 6.4.
7.
Start the feeder and check the metering auger for proper rotation.
CAUTION: When facing the open (discharge) end of the discharge cylinder, direction of
rotation of the metering auger MUST be clockwise (CW). If rotation is not
correct, resultant damage to the feeder may occur. In addition, product
discharge out of the feeder must fall freely and without any restriction
whatsoever.
NOTE:
Operating the feeder in the incorrect direction (especially when filled with product) could
cause the metering auger to detach from the threaded connection to its drive shaft.
Should this occur (on a feeder which is filled with product), most likely, the feeder will
need to be emptied in order to re-attach the metering auger.
Also, if the feeder’s Intromitter (or conditioning auger) is equipped with a threaded
connection (optional), the same situation (as described for the metering auger) can
occur.
8.
Fill the feeder’s supply hopper with product.
NOTE:
When in operation, product level in the feeder’s supply hopper should be kept at least 4
inches above the top of the Intromitter (conditioning auger). Below this level, inaccurate
feed may occur.
9.
Allow the feeder to operate for approximately one minute to allocate time for the feeder to properly
“condition” the product and to ensure that the metering auger is operating with a complete supply
of material.
10.
While the feeder is operating, set the feed output at a given setting and collect a few samples for
a predetermined timed interval. Weigh these samples and adjust the variable speed drive
accordingly to obtain the desired feed rate.
3.2 Feed Output Adjustments
3.2.1 Variable Speed DC Drive
The discharge rate of any particular size metering auger may be adjusted over an infinitely
variable 30:1 or 50:1 drive turndown ratio (depending on the selected model SCR/DC controller)
by adjusting the output speed of the variable speed drive. For complete information, please refer
to the applicable SCR/DC controller instruction manual.
