Right Hand Control Box | |
The control panels for the screed burners are located on the screed. There are two control panels on the screed. The left control panel controls the left screed burners. The right control box has the control switch (1) for the screed burner fuel pump. The right control panel controls the right screed burners. There are two switches for the screed burners. Each set of screed burners has a switch that controls the glow plug and the fan. Each set of screed burners has a fuel control valve. Switch (2) controls the main burners. Switch (3) controls the burners on the screed extensions. The standard 2438 mm (8 ft) screed has two burners. Each standard screed extension has an additional burner. Some 914 mm (3 ft) screed extensions have an additional burner.

- Hold the switch in the ON position (3) for a maximum of 10 seconds in order to warm the glow plug.
- Hold the switch in the ON position (3) . In order to start the burner, slowly open the fuel valve for the burner.
- When the fuel ignites, release the switch. The switch returns to the FAN position (4) .
- The burners will burn for 15 minutes in this position.
- Repeat the steps in order to light each burner.
Note: Only light one burner at a time.
Note: The ambient temperature and the asphalt mix will vary the amount of required usage of the screed burners. In order to avoid warping the screed wear plates, do not overheat the screed wear plates.

Main power button (1) - This button controls the burner system. The main power button (1) is only active when the generator is operating. When the screed's heaters are OFF, a single depression of the main power button (1) causes the heater's electronic control module to operate the screed's heaters. When the screed's heaters are ON, a single depression of the main power button (1) causes the heater's electronic control module to discontinue the operation of the screed's heaters.
Main power indicator (2) - The heater's electronic control module illuminates this indicator when the screed's heating system is in operation.
Low temperature indicator (3) - The low temperature indicator (3) will illuminate when the system is in the low temperature mode. The system defaults to this mode upon start-up. When the low temperature indicator (3) is illuminated, the temperature setpoint is 93 °C (200 °F), and the screed's heaters will operate until the temperature setpoint has been reached.
Note: If an error is detected for the temperature sensor, the manual mode is activated. In the manual mode, the temperature setpoint is 93 °C (200 °F), and the screed's heaters will operate for 30 minutes. The manual mode will only activate when an error message is present for the temperature sensor.
Temperature controller (4) - The temperature controller (4) allows the operator to choose between three temperature setpoints. The indicators above the temperature controller specify the selected temperature setpoint. When the temperature controller (4) is depressed, the system will increase the temperature setpoint to the next highest value. If the system is at the highest value, the system will cycle to the smallest temperature setpoint.
Medium temperature indicator (5) - The medium temperature indicator (5) will illuminate when the system is in the medium temperature mode. When the medium temperature indicator (5) is illuminated, the temperature setpoint is 116 °C (240 °F), and the screed's heaters will operate until the temperature setpoint has been reached.
Note: If an error is detected for the temperature sensor, the manual mode is activated. In the manual mode, the temperature setpoint is 116 °C (240 °F), and the screed's heaters will operate for 45 minutes. The manual mode will only activate when an error message is present for the temperature sensor.
High temperature indicator (6) - The high temperature indicator (6) will illuminate when the system is in the high temperature mode. When the high temperature indicator (6) is illuminated, the temperature setpoint is 132 °C (270 °F), and the screed's heaters will operate until the temperature setpoint has been reached.
Note: If an error is detected for the temperature sensor, the manual mode is activated. In the manual mode, the temperature setpoint is 132 °C (270 °F), and the screed's heaters will operate for 60 minutes. The manual mode will only activate when an error message is present for the temperature sensor.
Error indicator (7) - The error indicator (7) alerts the operator when there is a fault in the system. The electronic control module creates a sequence of flashes on the error indicator. Each flash sequence represents a specific fault in the system.
Right extender's temperature indicator (8) - The right extender's temperature indicator (8) will illuminate when the right extender has exceeded the temperature setpoint by 11 °C (52 °F). If the electronic control module detects a fault in this circuit, a flashing error code will appear.
Right main temperature indicator (9) - The right main temperature indicator (9) will illuminate when the right main screed plate has exceeded the selected temperature setpoint by 11 °C (52 °F). If the electronic control module detects a fault in this circuit, a flashing error code will appear.

Starting the Heater for the Screed
- Start the engine. Allow the engine and the machine to properly warm up. Refer to the Operation and Maintenance Manual for your paver for the procedure on starting the engine and for warming up the machine.
- Turn on the generator for the paver. Refer to the Operation and Maintenance Manual for your paver for information on the generator control.
- Press on/off control button (1) in order to turn on the heater for the screed. The power on indicator (1a) will illuminate.
Note: When the heater for the screed is turned on, all of the indicators will illuminate momentarily as a system check.
Note: The set point of the temperature is automatically set at the low temperature setting at the initial start-up.
- Press the button for the temperature control (2) in order to select the desired temperature setting. Press and release the button for the temperature control (2) in order to scroll through the different temperature settings.
Note: The heating time for the screed will not decrease if you select a higher temperature setting.
Shutting Down the Heater for the Screed
- Press on/off control button (1) in order to turn off the heater for the screed.
- Turn off the generator for the paver. Refer to the Operation and Maintenance Manual for your paver for information on the generator control.
Manual Overrides for the Heater on the Screed
The manual override can be used when a failure of the temperature sensor occurs. When a failure of a temperature sensor occurs, the indicator will flash. The indicator will flash once per second. Press the manual override button for the burner that has the sensor failure. The heater will operate for a predetermined amount of time. The duration of the heater operation will depend on the temperature setting that is selected. When the low temperature setting is selected, the screed will heat for 30 minutes. When the medium temperature setting is selected, the screed will heat for 45 minutes. When the high temperature setting is selected, the screed will heat for 60 minutes. After a predetermined amount of time, the heater for the screed will turn off. You can continue to press the manual override button in order to operate the heater for the screed until the sensor can be repaired or replaced.
