1.2 Design and Main Features

The Sperry Marine Rudder Angle Indicator System(RAIS) is a system for
electric rudder angle indication on maritime vessels.

The Rudder Angle Indicator System has been type approved by
DNV GL SE based on the

notification of the Federal Maritime and Hydrographic Agency of
Germany in compliance with the requirements of Marine Equipment
Directive (MED) 2014/90/EU of July 2014 as amended and is found to
comply with the requirements in the following specified regulations /
standards:
Regulation (EU) 2017/306, item No. MED/4.20.SOLAS 74 as amended,
Regulations V/18, V/19 & X/3
IMO Resolutions: A.694(17), MSC.36(63), MSC.97(73), MSC.191(79),
MSC.302(87)
and applicable to tests according:
(IEC 60945(2002) incl. corrigendum 1 (2008), IEC 61162series, ISO
20673(2007) and IEC 62288(2014)

and has been assigned certificate no. 47252-12 HH / 47253-12 HH.

For further details see “Declaration of Conformity” on page 1-9.

The RAC is used to attain ISO_20673 compliant overall calibration accu-
racy in RAI systems with conventional moving-coil indicators. It reads
the analogue signal from a rudder angle feedback unit and provides six
individually calibratable analogue signal outputs, and illumination sup-
ply terminals for the connected RAIs. To increase the number of availa-
ble outputs, two RACs may be connected in parallel to one feedback
potentiometer.
The RAC also provides two calibrated rudder angle outputs in serial for-
mat using the $--RSA sentence according to IEC 61162 (NMEA 0183).

To alert the operator of power failure and other alarm conditions, the
RAC provides two status relay signal outputs and also transmits alarm
status data via the $--ALR sentence according to IEC 61162 (NMEA 0183).
