1.3 About CCI.TECU
A vast range of electronic components are used in modern tractors. In addition to
sensors for the capture of operating data these are, above all, comprised of
electronic control units (ECUs) for the control of various tractor functions. The
electronic components are, as a rule, interconnected via a so-called bus system
and use this to exchange tractor information such as driving speed or power take
off speed.
The tractor ECU (TECU) is required so that information such as driving speed,
power take off speed or the current position of the 3-point hitch can also be made
available to an ISOBUS implement.
On an ISOBUS tractor, the TECU establishes the connection between the tractor
bus system and the ISOBUS and thus provides the implement with the
aforementioned information.
New tractors are often already ISOBUS-compatible ex works and fitted with a
TECU. Such TECUs are hereinafter identified as primary TECUs.
The vast majority of tractors in use are, however, not ISOBUS-compatible but can
be retrofitted using an upgrade cable set. However these cable sets do not usually
include a TECU, i.e. the connection from ISOBUS implements is possible but
access to tractor information is not.
The CCI.TECU described in these operating instructions closes this loophole. The
app concerned is an upgrade solution.
Using CCI.TECU, tractor information is read out via the signal connector and
transferred to the ISOBUS implement.
1.3.1 Active/passive mode
If only CCI.TECU is available on the tractor, it works automatically in active mode.
In active mode
1. CCI.TECU reads out the signal connector signals,
2. CCI.TECU calculates values for speed, power take off speed and 3-point hitch
position and
3. CCI.TECU sends the calculated values for speed, power take off speed and 3-
point hitch position to all ISOBUS implements.
If the tractor has a Primary TECU or a TECU of higher priority is available that
provides the tractor information via the ISOBUS, CCI.TECU automatically switches
to passive mode.
In passive mode information which is available via the ISOBUS is shown, a
connection to the signal connector is only necessary if not all tractor information is
provided via the ISOBUS (see chapter 4.4)
1.3.2 Hectare counter / documentation
CCI.TECU offers a hectare counter as an additional function.
The hectare counter is used to display ground coverage, working time and distance
travelled. Recording of ground coverage is performed by measuring the working
route and multiplying the adjustable working width.
The documentation function of CCI.TECU supplements the hectare counter with a
logging of process data. The process data are saved by CCI.Control in the active
task.
1.3.3 Delayed switch off
If the (ISOBUS) tractor is switched off by turning off of the ignition switch, ISOBUS
implements can automatically cause a delayed switching off of the (electrical)
