AccuMeter Controller Chapter 12: Quick Startup and Calibration 84
Step 4: Calibrate each feeders
• It is necessary to perform a feeder calibration with material to initialize the feed
algorithm. The controller will automatically determine this, but by doing so you
decrease the amount of learn time required. It is easy to perform and is
recommended that every time you switch resins with significantly different weights
and flow values that you run a feeder calibration.
• From the popup page touch the “Calibrate Feeders” tab
• Turn on the vacuum system and convey material or hand fill material into each
supply bin above weigh hopper. You will need enough material to completely fill
the weigh bin. You can use the blue color indicator as a guide.
• Touch “Press Here to Begin”. Be sure that the feeder is in “target speed mode” and
not in “target throughput mode”.
• After touching the “Press Here to Begin” button the controller will first fill the
hopper, then will run the feeder at max speed to prime the feeder, after a short time
the motor speed will be set to “Motor Speed for Calibration” and it will continue to
dispense an additional amount determined by “Dispense Weight for Calibration”.
These values are factory set, but may be adjusted. If during this process you see
the “loading arrow” above the graphic for the hopper then you do not have enough
material.
• Once finished the “Measured Feed Factor” will be shown and can be recorded for
future reference of the material. Doing this eliminates having to perform a feed cal
when you switch material. The operator can simply enter this known value into the
box.
• Repeat this process for all feeders.
