6.10.2 CALIBRATING GRANULAR BIN APPLICATORS
You will need to calibrate the feed mechanism of the granular co-applicator bin. Use the initial calibration
number supplied by the equipment manufacturer. If an initial number is not available, you can estimate an
initial calibration number by dividing the weight discharged during one revolution of the feed mechanism by
the number of sensor pulses generated during each revolution. Multiply the result by 1,000,000 and multiply
that result by the product density (pounds per FT
3 ). Use this number for the initial calibration.
For LORAL Air Max co-applicator bins, use the following initial calibration numbers:
A. Use the following switch settings to start the calibration (Be sure and set the proper product density,
section 6.1.4):
Power ON
Mode selector SET-UP
Display Selector L & CHEMICALS, VOL. APPLIED
Channel 1, 2 or 3 ALT RATE POSITION
(Select only one channel at a time)
All booms ON (for observing split drive channels)
TASC will display the current calibration number for the channel selected. Change the number
using the INC/DEC switch. Record the number for reference.
(Remember, if the channel is set
for split drive, the booms must be ON to view the calibration number, turn the booms OFF before
proceeding further.)
B. Set the mode selector to OPERATE, rotate the display selector to TEST SPEED and turn ON
the booms. Allow material to discharge until you are sure the flow is even.
(NOTE: Channel C or
L must also be turned on, set that channel application rate to 0.0 (zero) to keep alarms from
sounding.) Turn OFF the booms.
C. Rotate the display selector to L & CHEMICALS, VOL. APPLIED and use the DEC switch to
set the display to zero.
D. Divert the output of the selected channel to an appropriate catch container. You will need to
collect enough material to give a good sample. You will need to be able to measure the collected
material very accurately.
E. Rotate the display selector to TEST SPEED and turn all booms ON. The channel selected
will discharge into the catch container. When enough material has been collected, turn OFF the
booms and rotate the display selector back to L & CHEMICALS, VOL. APPLIED.
The minus sign indicates this is a non-peristaltic drive channel.
