CAUTION
A
Risk of damage
As the feedback potentiometer supply voltage is provided by the Rudder
Angle Calibrator, connecting the RAC to a feedback potentiometer in par-
allel to any device other than a second Rudder Angle Calibrator bears the
risk of damage in case of wire breaks or short-circuits.
Never connect the RAC to a feedback potentiometer in parallel to any
device other than a second RAC.
CAUTION
Risk of misusage
The ALR sentence as serial output of the RAC is not MED complaint and
therefore NOT allowed as system setting for a ship under wheelmark
certification.
Always make sure that the ALR sentence setting is INACTIVATED when
the RAC is used on a ship under wheelmark certification.
CAUTION
Risk of misusage
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.
Always make sure that another baud rate setting (4880 or 9600 baud)
must be selected as RS-422 output 1 and RS-422 output, when the RAC is
used on a ship under wheelmark certification
Note Generally, it cannot be guaranteed that the Rudder Angle Calibrator’s
parameter settings are left intact during a firmware update.
Before updating firmware, record all parameter settings to be able to re-
enter them manually, if required.
Calibration settings will not be touched when updating the firmware.
Note For recording all parameter settings see “Setup and Configuration
Tables” in the appendix of this manual.
