C), locate the cause of the overheating. Overheating
can be caused by excessive load on all systems on a
warm day, air ow through the oil cooler(s) restricted
and/or by a system that is constantly exceeding
relief pressure. The overheating can be corrected
by reducing the load on all systems on a warm day,
cleaning the oil cooler ns, and/or by reducing the load
on the various systems to maintain pressure below

A defective emergency stop system may cause
severe injury or death. Do not operate the
machine with an inoperative emergency stop
system. Check the emergency stop system daily
for proper working order before beginning paving
operations.
Fault Reset ( ) Switch: Used to reset the controller
when a fault has been detected. The reset switch
should be activated (moved upward and released)
whenever the fault/standby indicator lamp is
illuminated. If the lamp is ashing, refer to the fault/
standby indicator lamp explanation below.
Emergency stop switches must be reset and all faults
must be removed prior to activating the fault reset
switch. The controller will distinguish faults as minor
or critical faults. Minor faults require the repair of the
fault, pushing the fault reset switch to remove the
active fault and pressing the run/standby switch to
resume pouring operations at the previous settings.
Critical faults require all potentiometers and direction
switches be returned to the “off” or “neutral” position
before resetting the controller. Refer to the controller
active fault display for more information.
Note: Placing a faulted control loop in manual
(M) may allow manual operation of the system
depending upon the type of fault detected.
Fault/Standby Indicator Lamp: Used to indicate
when a fault occurs in the control system or when the
controller is in “standby” mode. If a fault is detected,
the lamp will remain illuminated and the controller
will stop all machine functions. If the controller is in
“standby” mode, the lamp will ash. Activate the fault
reset ( ) switch to reset the system. If all faults have
been corrected, the lamp will ash. The ashing lamp
will go out when the Run ( ) switch is depressed.
Note: The fault/standby indicator lamp will be
illuminated after initial start up of the engine as
well as whenever an emergency stop switch has
been depressed.
Emergency Stop Switch: Used to stop all functions
on the machine. Emergency stop switches are located
on the control console and on each elevation leg (two
emergency stop buttons are possible on each leg).
The switches must all be pulled out to operate the
machine. If any switch is depressed, the machine
travel, trimmer, auger/conveyor, vibrators and lift
circuits will be deactivated. Refer to the active fault
display (see later) to determine which E-stop switch is
at fault (depressed). After the emergency stop switch
is pulled out (reset), it will be necessary to reset the
system by activating the fault reset ( ) switch. Make
certain all controls are in the "off" or "neutral" position
before resetting the emergency stop system. To
resume travel in either direction, place the controller
in the "run" mode, depress the desired travel direction
switch and rotate the travel variable control dial to the
desired setting.
Note: All emergency stop switches must be pulled
out to operate the machine. The operation of the
emergency stop system must be checked every
day before beginning operation.

a grade sensor moves up or down, a bar appears in
the top or bottom half of the indicator.
The bar will change in color from green, to yellow, to
red as the signal strength increases and will change
from red to yellow to green as the signal strength
decreases. The deviation signal has a numerical
value from "0" (centered) to "±1000" (maximum
strength) that can be viewed or hidden by pressing
the ◄ navigation button. The green bar will appear
for a signal strength from "0" to "125". The grade
sensor wand movement will be from centered, to
approximately 0.375 in. (10 mm). The yellow bar
will appear for a signal strength from "126" to "400".
The grade sensor wand movement will be from 0.375
in (10 mm) to approximately 2.0 in (50 mm). The
red bar will appear for a signal strength in excess of
"401". The grade sensor wand movement will be in
excess of 2.0 in (50 mm) (may cause "off stringline"
to be displayed). If there is no error signal, the bar
disappears (centers). The steering deviation signals
will be similar to the grade.
The deviation numerical values for the smart cylinders
are shown over the steer deviation meters. The
rectangular indicator that is centered between all the
deviation meters will show the steer sensor deviation
on the appropriate side.
Note: The (~) mark shown in the left front
elevation indicator appears when the bump lter
(see later in the setup menu) has been activated
and a bump has been detected.
The automatic or manual control mode of each
individual control loop is indicated by the letter “M”
(manual) or the letter “A” (automatic) next to the
corresponding display. If the control loop is in manual,
the letter “M” will be illuminated next to the indicator
(the indicator rectangle turns red when the control loop
is in manual). In the manual mode, the corresponding
system will respond to the jog switches. If the control
loop is in automatic, the letter “A” will be illuminated
above the indicator (the indicator rectangle turns green
when the control loop is in automatic). In automatic,
the corresponding system will respond to signals from
the sensor. The jog switches will override the sensor
signals when the control loop is in the automatic mode.
Press the appropriate A/M switch to change between
automatic and manual.
Slope setpoint section: The slope setpoint section
