PTO MANAGEMENT
▶
Interventions that are carried out which do not comply with the following indications, may cause
serious damage to the on-board systems (not covered by the contractual warranty) and could
compromise the safety, reliability and correct functioning of the vehicle.
General information
The PTOs are activated by means of solenoid valves and engagement is verified by the "PTO Detection" signal.
"PTO Management" includes safety and control functions and in particular, if the engagement has occurred correctly, carries out
"Intermediate speed control".
The "PTO Mode" configuration (most advanced definition) requires programming of the Expansion Module (EM) and the Vehicle
Control Module (VCM). The EM is able to drive up to three PTOs and controls their activation and deactivation individually.
The following two conditions must be met to permit activation of a PTO:
1.
mechanical engagement
2.
recall of a "PTO mode" to be paired
These actions, can be carried out with two separate commands and in sequence, or with a single command from the PTO switches
on the central island console in the cab.
▶
Only use the signals available on the Bodybuilder connectors (such as parking brake engaged
signal, vehicle stopped signal, reverse not engaged signal) to ensure correct PTO management
and prevent the risk of drive train damage.
Definitions
Multiplex
Hi-MUX indicates the set of two control units: Body Computer module (BCM) and Frame Computer Module (FCM).
They are connected to the other electronic systems (EDC, VCM, ECAS etc.) in the vehicle.
Information and messages are exchanged by means of Bus CAN lines
PTO switch (PTOsw x, x = 1, 2, 3)
Located in the middle of the dashboard, this is used to request an action relating to a given PTO (for example, depending on EM
programming, PTO engagement/disengagement, "Intermediate Speed Control" activation).
Since EM and VCM can control up to three PTOs, up to three switches may be fitted; each switch is connected to connector
ST14A (respectively to pins 18, 19, 20).
