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

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

INFO key, the programmer will display the

following message: “Protected by controller, can’t program.”
