CENTRAL COMMAND CONTROLLER
PROGRAMMING
We use the same controllers on nearly all of our machines. The controller’s embedded
computer needs a set of instructions to operate the machine. The instructions are the
program the computer runs and we can modify this program by changing it’s “parameters”.
This is what makes it possible to use the same controller in most of our machines but have
each one of them react differently. By changing these parameters we can make the piece
of equipment function in different ways. An example of this is by changing the parameters
we can make brush deck of a machine drop to the floor when the machine starts scrubbing
and then pick itself up when the machine stops. If we adjusted another parameter we could
make the brushes raise up when the machine went in reverse without having the operator
manipulate a switch. In order to change the parameters in a controller a T-194 programing
kit is necessary. With a laptop computer and the programming kit access can be gained to
the parameters of the machine and they can be modified to make the machine react differ-
ently.
The controller has 135 parameters that can be modified through programming. To program
the controller a programming kit and special software are necessary. The kit for this is
available from the factory. The part number for the kit is T-194 and it includes the following:
1 Central Command II Programmer CD
1 Controller computer interface cable
1 USB serial port adapter
1 Controller protected power cable
1 Jumper key
1 Latest version of the Electrical Service Guide
1 T-194 programming guide
1 Aluminum briefcase
This kit is required to make any changes in the program for the computer.
