Powertrain control unit,
PCU
Helm station control unit,
HCU
The PCU node is to be located in the engine room.
The PCU communicates with the engine and with the
drive or the reverse gear. It also communicates with
the helm station control unit HCU, via the standard
bus cable.
The HCU node is to be located close to the helm and
the components that it controls. It communicates with
the PCU via the standard bus cable.
The HCU is equipped with a LED (STATUS). When
installed the LED is flashing quickly when power
is on and is off when power is off. Connector X8 is
plugged.
IMPORTANT! On the PCU and HCU there is a
label (1), with serial no. and chassis identifica-
tion. There are also corresponding labels on the
engine. The reason for having individually pro-
grammed PCU:s and HCU:s is that the software
must correspond to each engine specification or
helm specification (equipment and functionality).
Please refer to chapter Identification of the PCU
and the HCU.
