Control functions
DMCI ENGINE MANAGEMENT SYSTEM
XF105 series
Deactivation of engine speed control
1.
On operation of the "OFF" function
(C907 - 6 / C916 - 4) or,
2.
if the engine brake is operated, or
3.
if the programmed switching-on conditions
are no longer satisfied, or
4.
if the vehicle is driven while the engine speed
control function is active and the vehicle
speed is higher than a specific maximum
programmed speed (e.g. when going
downhill), or
5.
if the engine speed drops below the
minimum value (due to an increase in engine
load), or
6.
if the engine speed goes above the
maximum value (due to a decrease in engine
load).
Note:
If the engine speed control has been activated via
the application connector (A068), this has priority
over activation via the steering column switch
(C907) or the steering wheel switches (C916).
Engine torque limitation
There are three different versions of engine
torque limitation:
1.
Torque limiting during engine speed control
2.
Multi-step torque limitation during engine
speed control
1. The engine torque limitation during engine
speed control can be programmed using
DAVIE XD. A certain percentage of the maximum
engine torque is then available. This allows PTOs
and the components driven by PTO to be
protected against overload. For a detailed
description of this engine torque limitation see the
document "Test and customer parameter
information DAVIE XD".
2. In the engine speed control function, the
engine torque can be limited to protect PTO-
driven components against overload. Three
different torque limitations are available for this
function by providing current to B11 and/or B8.
These torque limitations are fixed maximum
torque values with a maximum engine speed
limitation of 1500 rpm, see the table. This engine
torque limitation is not programmable using
DAVIE XD and must be released on special
request.
