POWER TAKE-OFFS 4-21 E UROCARGO Euro 4/5 Use of the power take-off with vehicle in motion If no limitations are necessary (e..g, on the torque, max. rpm, etc.) with a power take-off engaged, it is not necessary to activate any PTO mode. In this case however the available power of the engine for driving is reduced (given the simultaneous draw for the body) and this can give rise to pick-up trouble. In some typical cases (cement mixer, waste collection, etc.) this problem can be minimized by raising the idle speed. If however limitations are necessary (e..g, on the torque, max. rpm, etc.), it is necessary to activate a PTO mode. !
Especially with the vehicle in motion it is necessary bear in mind that, if a PTO mode is activated, the stored intermediate speed is activated at the same time and this can cause unwanted vehicle acceler- ation. External bodybuilders must ensure safe operation. Engagement or disengagement of the power take-off depends on the power take-off used and the needs of the external bodybuilder. For example: vehicle running (up to max. 30 km/h) with speed increased and power take-off engaged. For several applications (use of the tipping box-body, cement mixer, waste collection, etc.) higher speeds are needed also when manoeuvring. This can be accomplished by:
- saving the intermediate speed rate N res : fixed programming - intermediate speed rate N res : defined by the external bodybuilder - turning off intermediate speed rate: turned off with clutch or brake - accelerator pedal: on - CC buttons: off In this way the engine can work even with only the accelerator pedal set between the saved intermediate speed rate N res and the max. speed, N max . If V ZDR-aus is reached, the intermediate speed regulator and therefore also the increase in the speed is turned off. Changing the saved intermediate speed rate N res The intermediate speed rate can be modified separately for each PTO mode. We need to distinguish between two possibilities:
1) fixed programming (MODUS) For power take-off mode 0 (running mode) this possibility is not available; a change is only possible by reprogramming with MODUS at an IVECO Service station 2) free programming (by the driver) To change the intermediate speed rate you need to: - activate a PTO mode whose intermediate speed rate has to be modified - set the desired speed using SET+/SET - press CC Resume for more than 5 sec. Using the MODUS/E.A.SY. station must be preceded b updating the EASY software. NOTE PTO management Print 603.93.431 Base - January 2008
