POWER TAKE-OFFS 4-13 E UROCARGO Euro 4/5 PTO management 4.6 PTO management ! Operations which do not comply with the instructions specified by IVECO or made by non qualified personnel can cause severe damage to on-board systems, effect driving safety and good operation of the vehicle and cause considerable damage which is not covered by warranty. Figure 4.7 115534 4.6.1 General specifications 1) mechanical engagement of the power take-off; Activating a PTO requires the combination of two actions: 2) calling up a PTO mode to associate with the power take-off. See further on for the definition of the PTO mode.
Therefore the expression ”PTO activated” means that the power take-off is engaged and that one of the PTO modes is active; otherwise we will say that the PTO is only engaged. The actions 1) and 2) can be executed with two separate controls, in succession 1) - 2), or with a single control by using, as explained further on, the PTO switches on the central peninsula in the cab. Generally, the PTO can be engaged by electric control (activation of a solenoid valve) or pneumatic control. !
It is recommended to use the available signals on the bodybuilder connectors (for instance parking brake activated, vehicle stationary signal, signal indicating reverse not engaged) in order to ensure cor- rect management of the PTO and avoid possible damage to the vehicle kinematics. These signals must be taken exclusively from the bodybuilder connectors. PTO management Print 603.93.431 Base - January 2008
