3.3 Console light
Functional description
The intention is to supply the console workplace, with sufficient ambient light for working. If desired, the
light can be turned off completely, so that it does not distract the ship operator, for example during night
time. However when required the light can be turned on quickly, by means of a switch.
By turning the dimming potentiometer clockwise, the light intensity increases, and correspondingly
turning the potentiometer anti clockwise decreases the light intensity.
The light can be switched on or off, by pushing the to-way switch located just below the dimming
potentiometer.
If an external two-way light switch is installed for remote control of this console light, this switch should
be connected to the appropriate terminals on the primary connection board.
The gooseneck lamp is fed by a regulated DC voltage. The max. voltage supplied to the gooseneck lamp
is around above 12VDC.
The gooseneck lamp comprise a 3 pin XLR-plug with a release button. Pin 2 carries positive supply
voltage (+), pin 3 is connected to DC-. Pin 1 is not connected.
The supply for the dimming module is routed from the emergency batteries, through the connection board.
The light source is either by white LED´s or red LED´s. The use of LED´s greatly reduces current
consumption and heat dissipation normally associated with incandescent lamps.
