2.1.2 Electronic control unit (ECU)
Three different types of electronic control unit (ECU) are
used:
1. Motor vehicle (truck)
446 220 000 0
2. Attached vehicle (trailer)
446 220 001 0
3. Attached vehicle with TCE
(trailer with TCE)
446 220 002 0
Electronic units differ by HF signal structure and
connection to CAN bus (ID). Externally could be
recognized by type label.
Technical parameters
Operational temperature range: - 40°C to + 80°C
Storage temperature range: - 40°C to + 90°C
max +100°C for 2h
Voltage:
24V ± 8V DC
Protection:
IP 69K DIN 40050/IEC 529
Torque:
15 Nm ± 10%
Electronic control unit is mounted in central part of vehicle
to chassis, so that perfect HF connection with all wheel
modules and connection between vehicle control unit and
trailer control unit is ensured. For control units
preferentially use mounting system 960 730 350 4.
Wireless connection is provided by aerial inside control
unit housing, which guarantees pressure signal reception
from all wheels even for most difficult operating
conditions.
All changes from pre-programmed required values of tire
pressure are immediately recognized by comparison with
limit pressure values and pressure changes.
Incorrect values of tire pressures are displayed
immediately during start of the drive (if the unit is
permanently powered).
