OPERATOR’S MANUAL
GRANULAR RATE SETUP
MATERIAL LABEL
A user-defined material name entered (10 characters maximum) that
identifies the material configured for a channel on the Operate screen.
UNITS
Unit of measure for granular material are available in the following
parameters:
– lbs (kilograms) per mile (km)
– lb/mi ft (g/km-m)
– lbs per sq ft/grams per sq meter
– lbs per sq yd/meter
– lbs/kft2 (Kg/m2)
– lbs per acre (Kg/Ha)
SPREADER CONSTANT
Represents the number of pulses generated by the application rate sensor
per pound of material (P/LB or P/KG) discharged from the spreader. The
spreader constant varies for each granular material, spreader vehicle, and
gate height setting (if optional gate height sensor is installed and enabled).
If the spreader constant is known, the value can be manually entered via a
keyboard with no granular calibration required. For unknown spreader
constant values, a granular calibration should be performed.
CALIBRATION GATE HEIGHT
Calibration Gate Height displays only if the gate height sensor is enabled at
the Accessory Sensor screen (F9). If enabled, the calibration gate height
value displayed is the setting of the gate height (inches) as a result of a
performed spreader calibration.
IMPORTANT: The Gate Height must be enabled before a spreader
calibration is performed. Refer to the Spreader
Calibration procedure.
The original calibrated gate setting can be changed to provide a more
accurate granular material application by adjusting the conveyor speed.
– An increased gate height decreases conveyor speed
– A decreased gate height increases conveyor speed
If the sensor voltage is outside the range between the Closed and Open
position values, the display states Gate Low or Gate High. If Gate Low
displays, the signal from the sensor is exceeding the open voltage. In either
case, an alarm activates. The Gate Height should be checked and set at
the granular calibration it was ran for on that granular channel.
