Cycle Print Options
When enabled, Cycle Print outputs a cycle diagnostic report to USB. Below are the
output reports produced during the preset time interval. These reports display a
date / time stamp, the MGF ID number, Work Order #, Operator #, and Recipe #, the
current settings, current hopper content weight, on-time, dispensed weight, rate
adjustment, target, total weight dispensed in 10ths of grams, error %, cycle count
(cycle mode) refill of the hopper count, and signal indicator with a signal count in
seconds.

Interval Report Description
GRAVIMETRIC FEEDER ID# 000 WO 00000 RECIPE 00000 OP 000
ID#, WO, RECIPE, and OP are for tracking and identification only. These TAGS may be entered by the operator or downloaded
by MLAN communication.
LDR: 5.00%
The percentage that you have entered as the desired target percentage.
WEIGHT: 3402.1
The current weight reading at the end of the dispense cycle. This is the total weight of the color that remains in the hopper.
AVG. DISP 2.98
The average dispense since the last rate error correction has occurred, or since the hopper was last refilled. It is the accumulated
weight dispensed, divided by the accumulated cycles count.
TARGET: 3.45
The amount, in grams, that the feeder is targeting to dispense based on your entries of color percent, (LDR), and SHOT WEIGHT.
Shot weight times LDR (percent of color) will give you the target dispense.
ERROR: -2.8 (3)
The total error that has occurred to this point, since the last rate correction or since the hopper was last filled. In this example, we
have metered 1.9 grams more then we want, since the last correction. This is the "total" error. not one cycle, but all cycle errors
combined. The (3) is the trip point. If total error exceeds 3 grams, then a recalculation of rate will occur.
SIG ON: 8.07s
The length of the screw return time that was recorded on this cycle. This number is used to determine how fast we need to run the
auger to meter the required color uniformly over this time period.
SHOT WT: 69.0
The Gram weight number that you enter to tell the software how large a shot is being molded. It will include runners, and all parts
if this is a muti-cavity mold. In this example, 69 x 5% = 3.45 grams, shown above as the TARGET weight.
ON TIME: 171ms
On models using our 24 volt DC motor, we control motor speed by pulsing the motor every second for a portion of that second. In
this example, we will pulse the motor for 171 milliseconds, and then leave it off for the balance of the second, which is 829 ms off.
The software adjusts this number based on the metering rate is has learned, coupled with the machine screw ON TIME. As On-
Time varies, this number will also adjust.
On models using a stepper motor, the off time between steps is adjusted to vary the metering rate.
