Signal navigation lights AQUA SIGNAL 70 D
No. of approval: DHI/01/06/1/75
Horizontal sector 360"
Visibility 3 nautical miles
Signal navigation lights may be fixed mounted or hoisted. In case they
are fixed to the ship it is important that their horizontal arc of light is not
obstructed by parts of the ship or mast. Unavoidable obstructions should
by within an arc of 6° (pict. 5).
Wiring
All navigation lanterns AQUA SIGNAL 70, except the signaling lights for
hoisting. , are fitted with a cable 1, 5 m long (type: H07RN-F3G 1, 5; 3 x
1, 5 mm 0, oil and water resistant).
The lanterns AQUA SIGNAL 70 D are fitted with two cables.
Alternatively they may also be supplied with standardized plugs according
to DIN 89267 (11 Oie. 220 V).
In case it is necessary to renew the cable of a AQUA SIGNAL 70, the
socket holder is to be unscrewed (3 screws) and may be pulled out through
the top. Situated on its back is the terminal board with ground
attachment.
To renew the cables of a AQUA SIGNAL 70 D, it is necessary to remove
the upper socket mounting plate first. Now the upper cable can be
changed. The lower cable can be renewed as mentioned above.
Bulb and bulb change
There are 3 different bulbs in 24, 110 and 220 V. They have a socket P
28 and may therefore put in only in one defined position.
To change the bulb it is necessary to disconnect the plug first, to loosen
the safety screw, then turn the cover by its handle to the left and lift up the
cover. The bulb may then be changed from the top.
To change the lower bulb in the AQUA SIGNAL 70 D, it is necessary to
remove the upper socket mounting plate.
Service
All parts of the navigation lanterns are made of sea water resistant
materials a, do not need any special attention. Cleaning of the outside
every now and then may be of some use. It should be carried out only
with fresh water and soft materials or sponge. Acid chemicals or other
abrasive cleaning materials must not be used, especially not on the lens.
Important
Due to light specific reasons no paint or any other anticorrosives should be
applied to the lantern.
