G R A V I M E T R I C A U G E R F E E D E R
CONNECT SIGNAL CABLE
9. Standard equipped for contact closure applications only, your controller will be equipped with the supplied
cable lead and 5-pin connector. You will also have a 20’ length of cable with a mating 5-pin connector. This
cable will connect to the MGF controller using the connector, and the open end will be wired to your
equipment. The open ends leads should be wired to the screw signal normally open contact closure. When
the screw is retracting contacts will close and then open at the end of the retract. The time closed is used by
the MGF to adjust output. This 5-pin connector is also used with an extrusion following 0-10 volt signal.
See the MGF wiring diagram on page 39.
M A G U I R E P R O D U C T S , I N C .
10. If optionally ordered with 24 to 120 VDC or VAC plug the "SIGNAL" (gray) cord will be plugged into outlet that
is energized only when the screw is turning. Signal voltage can be from 24 to 120 VDC or VAC. The screw
signal on-time can not be less then 1 second. INJECTION time or CLAMP CLOSE time are options.
Description of Controls
1. POWER ON / OFF SWITCH - Turns power on or off. Switch light
is illuminated when MGF is powered ON.
2. START / STOP on-screen button - This on-screen button
provides a run signal to the circuit board. For the MGF feeder to
run, a screw turning signal MUST be present, providing power to
the screw signal cord, AND the RUN switch must be in the RUN
position. The only exception is when the PRIME feature is
selected. This will operate the auger without any Run signal.

of the extruder on the main screen. Next set the LDR
(Let Down Ratio) on the main screen. In CONTINUOUS
mode your MGF will run continuously at the calculated
rate (lbs/hr x LDR). Auger speed will adjust automatically
to maintain dispense rate.
Select Extrusion Following
for extrusion, where the MGF auger runs continuously by
following the 0-10 volt reference voltage of the extruder
screw. In this mode the first step is to set the XMO
parameter. Setting XMO will automatically calculate
extruder throughput on the main screen based on a 0-10
volt reference. See page 28 for XMO. Next set the LDR
(Let Down Ratio) on the main screen. In Extrusion
Following mode your MGF will run continuously at the
calculated rate (lbs/hr x LDR). Auger speed will adjust
automatically to maintain dispense rate.

Prime the MGF Auger / Calibrate
It may be necessary to prime the auger prior to running. Prime will allow the MGF to run without a
signal from the process machine. Run time is automatically limited to ONE minute. After one
minute the display will read “PRIME TIMED OUT”. During the Prime, the MGF automatically
calibrates the flow rate of the material. To Prime, follow these instructions:
Press
Display will show animated movement on the auger. A 60-second
counter will begin to count down. During this time the MGF will selfcalibrate and display CALIBRATED indicating that it has learned the
flow rate of your specific material and has adjusted the motor factor
accordingly. After CALIBRATED has displayed, the prime function can
be ended by pressing the BACK button, otherwise prime will continue
to run for 60 seconds, then timeout and alarm, displaying “PRIME
TIMED OUT”.
Press
To stop the prime function.
When the MGF settings are adjusted and the MGF is primed
with material, it is ready for operation.
Press the START button run the MGF.
What happens during NORMAL OPERATION
The software uses the information you have entered, lbs/hr (or shot wt) and Let Down Ratio, plus
the motor factor, to determine a correct percentage off-time between steps for the motor to control
speed.
Two 10K load cells detect the loss of weight after each dispense. Based on this feedback,
adjustments are made to the percentage off-time to maintain the correct metering rate.
In the CONTINUOUS mode the percentage off-time, (motor speed) is adjusted to hold the correct
loss in weight of the hopper.
In the CYCLE mode the speed is adjusted to meter the correct amount over the full screw signal
cycle time. A change in process screw signal time will result in an adjustment to motor speed.
Speed adjustment is based on the previous screw return time. If screw return time is SHORTER
then the PREVIOUS time, the auger motor will continue past the end of the run signal for 1
additional second. It will run faster on the next dispense to end in time.

Alarms and Troubleshooting
NO METERING - ALARM CODE:48
This alarm indicates that no loss in weight has been detected during the last
several cycles. After clearing the alarm, metering will continue, however the
alarm will not re appear until after you have remedied the problem.
The following conditions are required to generate the NO METERING ALARM
a. Before this alarm is checked, the system needed to have been running for at least 24
seconds.
b. If the MGF is in continuous or extrusion follow mode, the target rate needs to be more
than 7.5 g/min.
c. If the MGF is in cycle mode, the target rate needs to be more than 2 grams / cycle.
If the above conditions (a and (b or c)) are met, then the MGF will compare the current bin weight
with a captured value from 24 seconds ago.
d. If the MGF is in continuous or extrusion following mode, the difference between the two
weights need to greater than 10 times the target rate.
e. If the MGF is in cycle mode, the difference between the two weights needs to be greater
than 5 times the target rate.
If the above condition (d or e) fails, then a counter is incremented
If the above condition (d or e) passes, then the counter is reset to 0.
If the counter gets incremented past 3, then the NO METERING alarm is triggered.
In cycle mode, the NO METERING alarm is checked only at the start of every cycle.
In continuous or extrusion following mode, the NO METERING alarm is checked every RTU
update.
M A G U I R E P R O D U C T S , I N C .
LOADING TOO SLOWLY - ALARM CODE:49
If the loading feature is enabled and it takes more than LAT (Loader Alarm Time)
seconds to fill the bin to LHF (Loader High Level) grams then this alarm is
triggered.
PRIME ALARM - ALARM CODE:50
This alarm indicates that the 60-second Prime cycle time has ended. The Prime
function is used to prime the feeder and is accessible from the main menu. It
operates by running the feeder auger for one minute to prime the feeder then
alarms to alert the operator that the prime cycle has ended.
LOW WEIGHT ALARM - ALARM CODE:51
If the bin weight falls below the LWA (Low Weight Alarm) setting (Default 400g)
then this alarm will be triggered. If the bin weight rises above the LWA
parameter, then the alarm will shut off.
