1.1 System Description
Intended Use
The Sperry Marine Rudder Angle Indicator System (RAIS) is a system for
electric rudder angle indication on maritime vessels and must be oper-
ated only from appropriately trained and educated personnel familiar
with all mandatory safety and operating procedures.
The Sperry Marine Rudder Angle Indicator System (RAIS) in total con-
sists of the Rudder Angle Calibrator (RAC), a microprocessor-controlled
signal conditioning device for electric rudder angle indicators, a series
of Rudder Angle Indicators (RAI) and a series of Rudder Angle Feedback
Units (RAFU) including limit switches and lever linkages.
Not Intended Use
The Sperry Marine Rudder Angle Indicator System (RAIS) is designed
for marine purposes only and therefore not allowed to be used for the
navigation of inland water vessels and river boats.
The ALR sentence as serial output setting of the RAIS is not MED com-
pliant and must therefore permanently be inactivated for all ships under
wheelmark certification.
The RS-422 output 1 and RS-422 output 2 of the RAC is not
MED compliant in case 38400 baud are selected as interface setting.
The 38400 Baud setting is therefore not allowed for all ships under
wheelmark certification and another baud rate setting (4880 or 9600
baud) must be selected.
