Table 11.5 MPTS Switch Configuration
The MPTS feature defaults to four configurable switch inputs as standard and
this is non-configurable. If less than four switched inputs are required then the
unused programmable speed settings should be programmed with the
physical position enabled set to ‘NO’.
11.4.3 MPTS Installation
Four switch inputs are available on the ECM for a switch-controlled throttle.
The ECM may be configured so that different combinations of switch inputs
will relate to different engine speed demands. There are 16 different
combinations of states of these 4 switches, although not all of these
combinations need to be programmed.

11.5 Torque Speed Control TSC1 (Speed Control Over CAN)
A special J1939 message called Torque/Speed Control #1 (TSC1) allows
other electronic devices to control or to limit the engine speed. This message
is explained in detail in section 20 of this application and installation guide.
11.6 Arbitration of speed demand
In applications where there is more than one source of engine speed demand,
it is necessary to arbitrate between the different demands. The speed
arbitration does not apply to the PTO speed demand feature. There are 4
methods of arbitration:
67
PTO MODE - DISENGAGE (NC)
36
SWITCH INPUT RETURN
43
PTO MODE – LOWER / SET
52
PTO MODE - RAISE / RESUME
51
PTO MODE - ON / OFF
