The hardware is configurated by means of the switchboard SYSCON. The position
of the switches can be changed only in deactivated condition.
!
The function of the switch board SYSCON (system configuration) is described in chapters 2 "overview
", 3 "wiring" and 3.1 "power supply".
The switch board TIME defines the delay times for the gear shifting. The function is described in
chapter 4.4.
By the switches PARSEL (parameter selection), parameters are adjusted as e. g., for mechanical
throttle control, idle and nominal speed and, for mechanical gear shifting, the gear positions ahead
and astern. In addition, parameters for special functions are preset (see chapter 4.3 "speed", 4.4.
"gearing").
The switchboard CTRHEAD (control head) determines the function of the control head (described in
chapter 4.2 "control head").
