OPERATOR’S MANUAL
MATERIAL LABEL
A user-defined material name entered (10 characters maximum) that
identifies the material configured for a channel on the Operate screen.
UNITS
The unit type selected displays material application rate as follows:
gal/mile - Gallons per mile
gal/mift - Foot traveled per mile
gal/ft2 - Square feet per gallon
gal/yd2 - Square yards per gallon
gal/kft2 - Thousand square feet
gal/ac - Gallons per acre
K FACTOR
K Factor represents the number of flow meter pulses generated by the
sensor per gallon/liter of dispersed liquid for pre-wet and anti-icing liquids
through the flow meter.
The K Factor number stamped on the flow meter body is sufficiently
accurate for keyboard entry if the viscosity of the liquid is near that of water.
If the flow meter constant is unknown, the actual value will adjust to the
correct constant during the liquid calibration.
APPLICATION RATE METHOD
Two methods are available to control the application of material:
• STEP Method
• Rate Method
STEP Method
STEP Method allows rates to be changed by a fixed increment using the
Rate Increase/Decrease buttons on the switch module. STEP method
requires a Target Rate, Min/Max Rate, and Inc/Dec Step defined.
To select the STEP Method:
Maximum Rate establishes the maximum application rate in gallons per
mile (L/km) that the control will allow. Target Rate cannot be incremented to
a value greater than this established Max Rate.
1. Highlight the Step method selection box and press the Enter key on
the keyboard.
2. Select Yes and press the Enter key again.
3. Enter the desired target rate for material application to be controlled by
this channel.
4. Enter a minimum application rate limit for this channel.
5. Enter a maximum application rate limit for this channel.
6. Enter an Increase/Decrease Step value that sets the increase/
decrease rate.
