The actual alarm point is set by physical position in the bin. Still, LEVEL should be set to
agree with the sensor location. In this way, during alarms, the dividing point on the bargraph
between the solid and blinking sections is a valid indication of the approximate level.
The LOSHFT alarm will come on when the shaft speed drops below the alarm point pre-set
by the operator.
3.4.1 Shaft Rate Calibration
The procedure is to seed for an appropriate length of time while collecting the seeded material.
When test seeding is complete, the collected material is weighed and the weight is entered into
the monitor, which then calculates and displays the weight per revolution.
The mode is started at the monitor by first selecting the appropriate SHAFT display function
with the UP and DOWN arrow buttons, and then holding down the OK button until after the
long beep following 4 short beeps. The upper line will show START. The user presses the
MODE key to advance the screen when they are ready to start the calibration procedure. The
top line will show REVS and the lower line will show “0.00” and the appropriate unit of area is
displayed.
Seeding may now be started. Shaft revolutions are displayed in steps of
0.01. As long as display shows REVS, the monitor counts the number of
revolutions that the shaft has turned.
When the desired number of revolutions has been covered, the operator
will stop and weigh the collected material. This weight is then entered into
the monitor, which then calculates the weight per rev in lb/rev (kg/rev).
The operator may push the MODE button to advance the display the
screens in the order shown to the right. To obtain a valid application rate
value, a valid weight will need to be entered under the WEIGHT display.
Then, the calculated weight per rev is displayed under the WT/REV
display.
