1.2 General preconditions for the operation
(According to classification rules)
Indication of the current cruising command*
The current cruising command (speed, gearing position) must be indicated on every control station.
Indication of active control station*
It must be indicated on every control station which control station is in command.
If, from any control station, any other station is visible, the indication of current cruising command and
active control station is not necessary (e. g. on small yachts).
Capacity of independent actuation*
Besides the remote control, a second possibility of controlling speed and gearing must be provided.
Emergency stop-button*
A separate emergency stop-button for the engine must be installed on every control station
independent from the remote control.
*These components are not included in the MAREX SB delivery.
1.3 Mounting advice
Cables to be connected to the control unit must always be provided with the metallic cable joints
supplied. The joints are mounted as shown below:
Mounting work must be done only if the system is in voltage-free condition. The power supply must be
secured against activation in this case.
Mounting and commissioning work must be carried out by skilled personnel and in accordance with
the manual only.
1.4 Operating advice
Do not reach into the actuator while it is in operation. You risk injuring.
The remote control MAREX SB has been designed for the control of Diesel engines. If it is applied for
petrol or gas propulsion systems, its components must be installed outside the hazardous area. The
instructions for hazardous areas have to be followed.
