Product and technology-related safety instructions
2.6
Range of applications
The Marex OS II system has been designed for controlling diesel engines.
For use with petrol or gas engines the system components must be installed outside the
hazardous area. Strictly observe the regulations for hazardous areas.
IP protection classes
Observe the IP protection class of the devices.
Exclusively install and use all devices in accordance with the corresponding IP protection
class.
Devices with protection class IP20 may be used in cabinets or consoles, only.
Devices with protection class IP54 may be used in the engine room.
Only use devices with protection class IP67 in external areas.
Installing the Marex OS II remote control system in a propulsion system
Engine emergency stop
Operation of the system is only permissible with a separate engine emergency stop
system on all control stations.
Engine emergency control It is recommended to install a supplementary, independent engine emergency control
system in addition to the Marex OS II remote control system.
Twin engine systems with
one control station
Twin engine systems with one control station should be equipped with single control
heads of types 240/241 or with twin control heads of type 230. For twin control heads of
type 240/241, 244, 250, 251 errors can affect both sides and, thus, both propulsion
systems, due to their construction and design.
Installation works
Installation works may only be performed when the system is not under power. Take the
appropriate measures to prevent inadvertent switch-on of the supply voltage.
Wiring instructions
Observe the information provided in the special chapter “Installing and wiring devices” in
the “Devices and Adjustments” manual.
Setting up and checking the Marex OS II remote control system
Modification of control
parameters
Only modify the control parameters when the propulsion system is not running. The vessel
must
not
move. It must be anchored or moored.
Fine-tuning
Any fine tuning during a sea trial must be coordinated with the shipmaster. The safety of
the crew and other traffic participants must not be endangered. Take the appropriate
measures to make sure that erroneous entries in the course of the parameterization
process do not result in a loss of control of the vessel.
Checking the remote
control system
The responsible shipmaster is obliged to check the remote control system prior to each
journey. Additionally, the entire ship control system must be checked on a regular basis in
compliance with the seaman's duty. This overall check includes testing the control of the
propulsion system, checking the control stations, checking the exterior control stations for
leakage, performing a general functional test and examining the entire system for integrity.
