OPERATOR’S MANUAL
ROAD TEMPERATURE SENSOR
A road temperature sensor monitors road temperature changes. When
enabled, an alarm on the Operate screen identifies when defined road
temperature changes occur.
IMPORTANT: The RoadWatch Sensor adapter must be connected to
the Flex4 Interface cable that connects to the Rate
Control Module harness. The Interface cable must be
connected to the connectors labeled as Analog 1, 2, 3 or
4. The connection point for the road temperature and air
temperature must be identified at the F9 Accessory
Sensor screen.
Road Temperature status appears on Operate screen as:
67F
ROAD
TEMPERATURE
AIR
75F
To enable Road Temperature Values:
1.
At the Road/Air Temperature Menu screen, select the corresponding
number.
2.
Select Yes at the Temperature Enabled input box.
3.
Enter the alarm temperature in degrees F to alert of road temperature
changes to indicate when application rate or material changes are
required. Temperatures must be entered in descending order with
Alarm Temp 1 the highest setting and Alarm Temp 3 the lowest setting.
4.
Enter the temperature hysteresis that will clear the temperature alarm
when a positive temperature change has occurred. If Alarm Temp 1 is
20 degrees F and the Temperature Hysteresis is set at 5 degrees F, the
alarm activates when the temperature drops below 20 degrees F and
clears when the temperature reaches 25 degrees F.
5.
The High and Low Calibration values should not be changed and
should be created from the calibration routine.
6.
After values are entered, press C to begin the calibration procedure.
Calibration lasts approximately 10-20 seconds.
7.
Press “D” when done.
