LeeBoy 8608 - Plus One Controller

Status Icon Description
Diesel Particulate Filter Lamp. A Solid
Lamp is the initial warning that soot levels
are rising in the DPF. A Flashing Lamp indi-
cates a DPF REGEN is needed (on some
systems, the lamp will become RED when
ashing). The lamp will turn solid again
when a REGEN is initiated.
Any time the lamp begins ashing, the
operator should increase the loading
on the engine so that regeneration is
possible.
If increased load does
not cause an automatic REGEN to
occur, the operator should immediately
perform a Parked, Manual REGEN.
DPF Regeneration Set to Inhibit. The
user may choose to inhibit the REGEN
if conditions are too hazardous for high
exhaust temperatures. When this lamp is
illuminated, a REGEN cannot be performed
and soot levels will continue to rise.
Unless hazardous
conditions exist, the REGEN Inhibit
switch and this lamp should remain off.
DEF Tank Level Warning Icon. This lamp
illuminates if the DEF tank level runs low
(below 15 percent).
Insufcient DEF can
result in damage to the DEF injector and
other components.
Diesel Exhaust Fluid (DEF) System
Warning. Indicates a failure of the emis-
sion system or that engine emissions are
too high. The DEF may be contaminated
and need to be replaced, or the system
may need service. Contact your authorized
dealer for assistance if needed.
PLUS ONE CONTROLLER
The Plus One is a 50-pin controller operating in the
background that monitors paver control systems and
alerts the operator in the event of a fault. When the
Plus One controller senses a system fault, the Plus
One light on the control panel (Figure 4-50) illuminates
green and blinks continuously or blinks, then pauses,
then blinks again. A complete list of fault codes with
corrective action messages are shown in Section 5,
Troubleshooting.
Plus One Light
Figure 4-50. Plus One Light
When the key is turned on, the Plus One light will
illuminate for approximately three seconds while the
controller powers up, then turn off when the machine
is ready to start. The Plus One will not allow the engine
to start if any joystick is out of neutral or more than one
Run/Stop switch is in the RUN position.
These faults will prevent machine movement:
• Steering control box not detected.
• Joystick(s) not in neutral at start-up.
• Pump control coil fault.
• Brake valve/pump neutral bypass coil fault.
• The fault happens in the steering control box that
has control (Run/Stop switch in the RUN position).
• The fault occurs when neither steering control box
is in control.
