4. Adjust the P term accordingly for consistent oscillation and error. Progressively decrease the
P term value if there is too much oscillation and error. Likewise, increase the value if the error
is not consistent and oscillating around the setpoint. Refer to figures 1, 2, and 3 below.
5. Once the P term value is set to give the control output of the BW500 consistent oscillation
and the error is at its minimum, turn the feeder off.
6. The I term value can now be set. Begin by entering the default value of 0.2.
7. Restart the feeder (test weights or chains still applied) and feed rate setpoint entered.
