CONNECTIONS
It should be noted that when Super Halcyon 3 is used with Hercules alone, power is derived directly
from the Hercules Computer backplate.
When the Super Halcyon 3 is used independently, the power supply should be connected to the ship's
12/24V dc supply via a 1A fuse. For connection details, refer to installation sheet. Once the mounting
position has been chosen it is advisable to complete the wiring before securing the sensor unit in
place. Proper operation can then be confirmed by switching on and rotating the sensor unit about a
vertical axis. The variation in displayed heading will be clearly shown on either the repeater, or on the
Hercules digital display (note that for easy reading the latter is heavily damped). Whilst operating,
Halcyon 3 will emit a quiet high-pitched tone.
When correct operation has been verified, the compass should be lined up fore-and-aft using the
marks on the top. Once the initial calibration has been completed, the compass sensor may be rotated
for exact alignment before final tightening of the clamp screws. Do not over tighten. It is recommended
that the cable be firmly clamped near to the sensor unit as an aid to mechanical stability. Do not bend
the cable to a curve of less than 100mm radius adjacent to the plug.
