Normal Operating Sequence
This section tells you how the system is supposed to work. If your system is not operating
correctly, this description may help you spot exactly where the system is failing, providing a clue to
the problem.
Turn POWER ON:
A boot up splash screen displays showing MAGUIRE WSB with the current firmware
version displayed in the lower right corner. A status bar and Synchronizing with WSB
displays at the bottom. The controller should then display the home screen. The weigh
bin weight reading will display at the center of the home screen on the image of the weigh
bin. It should show 0 or +/- a few grams.
BEGIN operation:
The unit will begin to operate if the START button is pressed on the Home Screen and
the SENSOR in the mix chamber is UNCOVERED. The sensor must be plugged into the
right side of the controller. If it is not, this has the same effect as the sensor being
covered; the unit will not run.
If the WEIGH BIN DUMP Flap opens and closes repeatedly:
If initial empty bin TARE weight is 100 grams or more, the weigh bin dump valve will
operate in an attempt to empty the bin and bring the starting weight closer to zero. If the
bin is empty but the weight reading is greater than 100 grams then something is wrong.
See Verifying Load Cell Function on page 93.
If the ALARM flashes:
If the initial TARE weight is below -50 grams the Alarm will active with the Alarm Log
message Tare Low and the unit will not operate. Go to Verifying Load Cell Function on
page 93.
The DISPENSE sequence begins:
If initial tare weight is within limits, between (-50, +100), the blender will begin to operate.
Home Screen during dispenses:
During all dispenses, the component number being dispensed will highlight in yellow and
a dispense status meter will display in the center of the screen. Before the dispense
begins, the weigh display will show the tare weight of the bin. After the dispense of the
first material, the weigh display will show the total of the first material along with the batch
progress on the Dispense Status Meter. After the dispense of each material, the new
weight total weight is displayed and the Dispense Status Meter updates.
REGRINDS first:
If REGRIND is part of the blend, REGRIND dispenses will occur first in order of size,
from the largest to the smallest. After these dispenses an exact weight is taken to
determine the space remaining in the weigh bin for the remaining dispenses.
NATURALS second:
The NATURAL dispenses occur next in the sequence. They will be dispensed in
order of size, largest to smallest. The exact weight of all NATURALS dispensed is
weighed for calculating the ADDITIVE dispenses.
