8-6 LeeBoy Model 8510B Conveyor Paver
Troubleshooting
Controller User Guide
Startup
When the key is turned on the status light will come
on for approximately 3 second while the Plus One
powers up. The status light will turn off when the paver
is ready to start. If the light stays on this means that the
joystick(s) in the control box are not in NEUTRAL and the
Plus One will not allow the engine to start. Placing the
joystick(s) in NEUTRAL will turn off this light and allow
the engine to start. If the light starts to blink see the Fault
Code table in section 8 of this manual.
Optimization
After installing this software the steering control box(es)
will require optimization as well as calibration (which will
be discussed in the next section).
The software will automatically recognize which type of
steering control (Dual Joystick or Steering Wheel with
FORWARD/NEUTRAL/REVERSE (FNR) Joystick) is
installed and if there is one or two boxes connected. On
pavers with two boxes; the Plus One will only operate if
both boxes are of the same type.
NOTE: Plus One will not allow the Engine Enable to
come on until the Optimization procedure has
been done.
NOTE: If the pumps are the high current (Sauer H1 or
Rexroth) perform the pump selection.
Vibrator/Electric Actuator Relay
And Backup Alarm Outputs
Anytime one or more joysticks are in the FORWARD
position (none can be in REVERSE) the Vibrator/Electric
Actuator Relay +12VDC output is turned on. The output is
disabled in a counter-rotate condition.
Anytime a joystick is in the REVERSE position or a
counter-rotate condition exists, the Backup Alarm
+12VDC output is turned on.
Pump Control Outputs
The Plus One controller is setup to operate dual
hydrostatic pumps, two options are built in; the low
current outputs for the series pumps (default setting),
and high current outputs for the H1 series.
If the H1 pumps are used you must switch the Plus One
to high current outputs
Adjustment should only be done by an
Authorized LeeBoy Dealer.
To Set For High Current Output:
1. Turn the paver off.
2. Open the dash board panel and locate the High
Output connector and plug it into the High Output
receptacle.
Brake Release/Pump Neutral
Bypass Valve
This +12VDC output is turned on when any joystick is not
in NEUTRAL and the RUN/STOP switch is in the RUN
position. The output is turned off when the joysticks
are brought to NEUTRAL, the operators RUN/STOP
switched is switched to STOP or the opposite control
box is set to RUN.
There is a proportional time delay, based on output to
the pump coils. The maximum delay is 10 seconds if full
outputs to the pumps were present and the minimum
delay is 3 seconds. The time delay will start when the
joysticks are brought to NEUTRAL, the operators RUN/
STOP switched is switched to STOP or the opposite
control box is set to RUN.
When the run signal is returned the output is immediately
turned on and there is a 0.2 second delay on outputs
to the pump coil. This delay allows time for the brake to
release before the propel coils are energized.
