3 — ADJUSTMENT OF PARAMETERS
ADJUSTMENT OF PARAMETERS
A number of controller parameters can be adjusted electronically via the
optional handheld programmer; for a complete list of the adjustments that
can be made, see Section 6: Programmer Operation. On some 1207
models, it is also possible to adjust the main current limit, plug current
limit, acceleration rate, maximum creep speed, and maximum speed me-
chanically, by means of the built-in screwdriver-adjustable potentiometers.
ADJUSTMENT VIA THE PROGRAMMER
To change a parameter using the programmer, press the
PROGRAM
key, and
scroll down the Program Menu until the desired parameter is the top line
of the display. Press the appropriate
CHANGE VALUE
key (“up” or “down”)
until the desired number is reached. The parameter is now set at the desired
value. All programming occurs in real time. That is, the parameters can be
changed while the vehicle is in operation.
The upper and lower limits of parameters are set at the factory. Some
parameters have dependencies on other parameters. When the program-
mer is being used to adjust a parameter and a limit is reached, the display
will stop changing. To see why the display has stopped changing, press the
MORE INFO
key. If the limit is related to another parameter, that information
will be displayed; changing the value of the related parameter may allow the
original parameter to be adjusted further. Otherwise, the display simply
says “Max Limit” or “Min Limit.”
Use of the programmer is described more fully in Section 6.
1207 single-mode controllers only
If a programmer is connected when a parameter is adjusted mechani-
cally (see next page), the effect of the change can be seen in the
programmer display. To adjust one of these five parameters with the
programmer, its potentiometer must be set to the “
OFF
” position on
the adjustment panel. If you attempt to use the programmer to
adjust a parameter whose potentiometer is not set to the “
OFF
”
position, its value will not change. You will also note that the LEDs
in the corners of both the
CHANGE VALUE
keys do not light up—
another indication the parameter cannot be adjusted electronically.
If you press the
MORE INFO
key, the programmer will display the
following message: “Protected by controller, can’t program.”
