DU (Display Unit)
The DU is an computerized
instrument panel which shows engine working values on an LCD screen. In the
display it is possible to show multiple windows with different information, i.
g. engine rpm, coolant temperature, fuel consumption and fault messages. At
start up, the display performs a self-test. If an constant signal is heard, the
system has discovered a malfunction. The display will work but may act in an
unexpected way.
The DU is connected between the
engine control unit and the CIU or DCU.

CIU (Control Interface Unit)
The CIU is a
"translator" between the control unit (EMS) and the customer's own
control panel. The CIU has two serial communication links, one fast and one
slow.
The fast one is a so-called CAN
link. All data related to instruments, indication lamps, connectors and
potentiometers is controlled by this link.
The slow link manages diagnostic
information for flashing codes etc.
Easy Link Instruments
The following Easy Link
instruments are available:
- Tachometer / hours counter
(fault codes are also displayed on the tachometer display when the diagnostic
button is pressed)
- Coolant temperature
- Oil pressure
- Oil temperature
- Battery voltage
- Alarm panel
- Turbo pressure
