ROTARY RUDDER REFERENCE SENSOR
Installation of RRF
A number of key points must be considered for optimum performance of the unit:
Mount the unit on a flat surface next to the tiller arm or steering quadrant. Construct
a small platform if necessary.
Do not lengthen the drag-link arm as this can transmit excessive vibration to the
sensor.
The sensor operating arm can be rotated through 360º. The mid-point of the RRF
wiper travel is when the arm is opposite the cable entry point. The sensor arm
should be approximately opposite the cable entry point when the helm is in the
mid-ships position.
When the rudder is moved hard-over port or hard-over starboard, the RRF arm
should travel through a minimum angle of 90º to ensure sufficient voltage swing.
Measure the voltage difference between the blue (0V) and green (signal) wires
from the RRF; there should be at least a 1V dc change from port to starboard.
After fitting and connection of the RRF test the full movement of the steering gear
to ensure no fouling occurs between the ram drive, steering gear and RRF.
Check for backlash in the linkages. Excessive backlash will cause errors in the
operation of the Pilot.
The example opposite shows a plan view of a typical system with a tiller arm and
quadrant. When viewed in elevation, the ram drive arm and rudder reference unit
drag-link must not be more than ±9º from horizontal. Ideally, everything should be
horizontally aligned as this prevents excessive stress during operation.
