Section 3. Systems Overview Model 8210/8250 Maintenance Manual
Operator Display and Programming
3-8 Publication: 1146945/001, Revised: 25 Sep 2018
Programming Service Parameters
1. Connect the service key to the service key
connector J5. Make sure the Main
ON/OFF switch (SW1) is in the ON
position. See “Special Tools” on page 3-21.
2. Turn the truck ON while holding the horn
button until “P” is displayed. Release the
horn button at “P” to enter parameter
mode. The Parameter indicator (wheel
icon) on the display illuminates when in
parameter mode. See “Special Truck
Mode” on page 3-5. If the horn button is
released at the wrong time, turn the truck
OFF and start over.
3. Rotate the thumb control in the fork
direction to progress forward through the
parameters. While the thumb control is
held and briefly after it is released, both
the parameter number and the driver
number are displayed. Stop at parameter
10 (PIN code) for the first driver; the
default value of “1” is displayed. See
Figure 3-4.
4. Press the horn button once to access this
parameter. The parameter symbol on the
display flashes. Now you can make
changes to the value of the first driver’s
PIN code. See Table 3-5.
N
OTE: All parameters can be viewed; however,
not all parameters can be changed.
Driver parameters may or may not be
accessed, depending on the value of
parameter 39.
Parameter Displays
When parameters 1 through 5, and 10 are
viewed with the service key, both the parameter
number (left side of display) and the 1
st
operator number (right side of display) are
shown.
As the parameter number display progresses
through parameters 1 through 10, the display
rolls over to the next operator (the operator
number increases). If a parameter is changed, it
is valid only for the operator shown. After all
operators and operator parameters are scrolled
through, Service Parameters 11 through 49 are
displayed.
To quickly display/access a Service Parameter,
rotate the thumb control away from the forks
(sequence backwards through the
parameters/operators).
Setting Individual PIN-key Codes
1. Connect the service key at J5. See “Special
Tools” on page 3-21. Make sure that the
Main ON/OFF switch is ON.
2. Enter Special Truck Mode. See “Special
Truck Mode” on page 3-5.
3. Press and hold the horn button until “P” is
displayed. The parameter indicator (wheel
icon) is illuminated. If the horn button is
released at the wrong time, turn the truck
OFF and start over.
4. Use the thumb control to scroll through
the service parameters. While the thumb
control is held and briefly after it is
released, both the parameter number (on
the left side of the display) and the
operator number (on the right-this only
occurs if the service key is connected) are
displayed. Stop (release the thumb control)
at parameter 10 (PIN-key code) for the first
operator; the default value of “1” is
displayed.
5. Press the horn button once to access this
parameter. The parameter indicator on the
display flashes. Now you can make
changes to the value of the first operator’s
PIN-key code.
Changing the 1st operator’s PIN-key
code alters default operation. You will
not be able to press “1” and green ON
( I ) to power the truck unless an
operator’s PIN-key code is set to “1.”
6. Rotate the thumb control in the fork
direction to increase the PIN-key code
value, or in the operator direction to
decrease the value. Holding the thumb
control in a direction for a time helps
quickly advance to larger numbers (for
example, codes greater than 100). The
PIN-key code can be from one to four digits
