The MD310S Rudder Angle Telegraph is an emergency system which derives its power from a safeguarded backup DC power
supply. The MD310S system conveys angular steering commands from the wheelhouse to the steering crew located at a remote
station in the vessel’s steering gear compartment. In this way, the vessel can be safely steered when the main power has failed.
Steering commands are displayed in degrees by a moving pointer (also known as a bug) on the remote angular display unit
situated in the steering compartment. The steering crew can then comply by moving the rudders to the required angular position
by hand and then respond to this by confirming the response angle and pressing the Alert button.
