PTO management
4.6.2.4 Multiple State Switch
This is an additional fu nction for engine rpm management with PTO engaged available on the 12-way Bodybuilder connector
(pin 3 - pin 8).
To obtain this function, the circuit given in the diagram in fig. 4.10 must be created.

Operation:
1) Vehicle stationary, with switch in 0 position:
- Manual operation - press RESume button on the Cruise Control to bring the engine speed to the programmed rpm.
- Assisted operation - supplying a positive signal to pin 15 of the 20-way Bodybuilder connector, t h e engin e speed will increase
to the programmed rpm value.
2) Vehicle stationary, with switch in 0 position:
- without pressing the RESume button, the engine speed will remain at idle. Upon changing the position of the switch, the
engine rpm will change to the programmed value for each swit ch position.
Placing the Cruise Control selector in the OFF position, or else by pressing the brake or clutch pedal, the engine speed control
func t ion will disengage independently of the position t he switch is in.
Whenever it is necessary to store engine speed values different from the default values set by IVECO, the system allows the desired
values to be programmed for each selector position by following the procedure described in section 4.6.2.3.
