4-22 POWER TAKE-OFFS E UROCARGO Euro 4/5 Adjustment of the minimum number of revs that can be reached with SET-, N SET_min 1) Activation of the idle speed setting The engine must run at idling speed - Operate the service brake (until the end of the setting) - Press the Resume button for more than 3 sec (and then release) Immediately afterwards the speed rate at idle speed automatically drops down to the minimum value. Adjusting the speed rate at idle speed can only be done with the engine warm. The adjustment is made in three stages: 2) Changing the speed rate at idle speed With CC SET+ or CC SET- it is possible to adjust the speed rate at idle speed in steps of 20 rpm.
3) Saving the speed rate at idle speed Saving is done by pressing CC Resume again (for more than 3 sec.) ! The speed rate at idle speed can only be adjusted in the PTO modes with which the CC buttons were activated or the intermediate speed rate adjustment was turned off with the brake or with the clutch. The adjustment interval for the speed rate with no load is factory set to 100 rpm. This interval can be extended to 200 rpm by reprogramming done by the Iveco Service. The adjustment interval for the speed rate with no load is identical for all the power take-off modes (running mode 0 power take-off modes 1, 2 and 3).
Influence of the retarder on the intermediate speed rate regulator Operating the retarder turns off the intermediate speed regulator (identical effect to the CC command Off). All the CC buttons (CC Resume / SET+ / SET-) are ignored with the retarder operated. If there is the configuration: Cutting off the intermediate speed rate with brake or clutch = off, and the intermediate speed rate is below 900 min -1 , on operating the retarder, the intermediate speed rate regulator is not cut off. When the retarder is operated, the engine speed rate is lowered to the speed rate with no load and all the CC buttons (CC Resume/SET+/SET-) are ignored.
After cancelling the operation, the original speed rate will be restored. ! PTO management Base - January 2008 Print 603.93.431
