Illumination
The white illumination element is visible at the glass dome of the compass. It is fixed by a
bracket to the glass dome. For replacement remove the white element and replace by a new
one.
The bulb is of glow type which means the wires of the cable can be connected to the battery
free of polarity. Use a rheostatic dimmer to reduce brightness of the light. In case of 12 VDC
ship`s voltage the recommended resistance is 400…500 Ohms, in case of 24 VDC it is
2000…2500 Ohms. Power consumption of the light is abt. than 2 VA.
Maintainance
From time to time the suspension has to be oiled.
Strong vibrations may blunt the point or pivot of the card assembly. Check this especially on
motor yachts with strong vibrations.
For this proceed as follows:
1. Locate the compass free of any interfering magnetic field. Note the heading when the
directional systems stops the move.
2. Use a weak magnet (iron key for example) to deflect the card not more than 2° and
wait until the movement of the card stops.
3. Pull away the deflection iron or magnet and wait until the card stops to move.
4. If the card returns to the originally noted heading within a tolerance of +/- 0,5° the pivot
should be still in order. If not you have to send the compass to a compass workshop
for replacment of the pivot.
Errors
Bubbles:
Air bubbles inside the compass do not disturb the indication as fas as they are smaller as
about 10 … 20 mm. Nevertheless they should be removed when a workshop can be
reached. In case of larger bubble the compass should be taken out off order.
Tilt of directional system:
When sailing in south hemisphere a small down of the south part of directional system is
usually because of the different vertical magnetic field. If the inclination is too much this can
show a leaking float. Contact a compass workshop and ask to replace the system, the
compass should be taken out off order.
