Operation
Screed Extension VibrationScreed Extension Vibration
Screed vibration helps compact material. If equipped
with this option, use the Vibrators switch on the main
control panel to turn vibration on and off.
Automatic Temperature ControlAutomatic Temperature Control
Automatic temperature control (ATC) for heating the
screed is an option that offers additional convenience
for operators, automatically turning the heating ele-
ments on and off to maintain desired screed tempera-
ture. The ATC control is on the side of the electric heat
box. (Figure 4-78)
It is only available with the Legend HD screed option.
The ATC unit is located inside the screed heat control
box.
The green numbers that illuminate on the controller
is the set point temperature. Use the UP and DOWN
arrows to increase or decrease the set point tempera-
ture. The screed temperature appears in red numbers
above the set point temperature. (Figure 4-79)

Figure 4-78. Automatic Temperature Controls
Start with a set point temperature of 200° - 250° F. The
screed runs warmer than the set point temperature due
to heat soak, which is normal, so it’s better to start with
cooler a temperature set point. The displayed tempera-
ture (in red) must fall 25 degrees below the set point
before the heating elements turn on again.
