Material
If more than one material has been pre-defined in the material calibration setting section, the
material can be changed here. This allows for multiple weight calibrations, minimum and
maximum dispense settings, and varying blast rates.
Fill Tank
On a pre-wet-equipped system, the
SpreadSmart Rx
TM
maintains the tank level by calculating
the amount dispensed. When the tank is filled, the level in the
SpreadSmart Rx
TM
unit must be
updated to reflect this. By simply pressing pre-wet (+) the tank level is re-set to “full”. Should
you choose to partially fill the tank, you can estimate the displayed percentage by pressing the
pre-wet rate button (up or down) to change the tank level to estimate a partial fill. Correctly
setting this feature enables the low level warning system (which functions in open or closed loop
set ups), but does not affect the automatic pump protection system. Automatic pump protection is
only possible in closed loop systems which give flow sensor readings to the controller.
Common Methods of Operation in Automatic Mode
Using Named Materials with Flexible Rates:
A common operating mode is to name the material(s) being distributed, but not to pre-
determine the rate at which the material will be distributed. This allows the operator to use the
SpreadSmart Rx
TM
touch screen to respond to changing conditions by adjusting the material
distribution. Following the instructions in the “managing materials” section of the manual will
allow you to designate the material name, the full range of rate applications allowed (min and
max) and the increment at which the rate can be changed using the touch screen.
Using Named Materials/Rates with no changes allowed:
Many sites choose to pre-set the actual rate of material distribution and not allow changes
by the operator unless another material name (with a different program) is chosen. This method
defines the particular amount of material (lbs/lane mile) that will be distributed during the run.
The actual rates will vary by location and type of material being spread. Following the
instructions in the “managing materials” section of the manual, allows you to set the minimum
rate of distribution equal to the maximum rate of distribution, thereby allowing “no changes” to
the settings you have chosen. The rate change switches on the
SpreadSmart Rx ™
will not
change the material distribution setting once the “pre-programmed material name” is selected in
automatic mode.
Using Named Materials with Programmed Rate Change Increments:
This method of operation allows the operator to change rates of distribution during the
course of a run, but only within the limits (min and max rate) and at the increments (100 lbs, 250
lbs, etc) that is designated. This method gives the operator some discretion at setting his
distribution, but only within planned limits. Following the instructions in the “managing
materials” section of the manual, allows you to set the min. and max. rates of distribution as well
as the rate change increments to create the range of operating limits you wish to achieve.
