DLQA96/144
Marine bridge instrumentation
4189350016B (UK)
1. Description
The illuminated X-coil instruments types DLQA96/144 are designed for marine
applications. The instruments can be applied as rudder indicator, azimuth indicator,
compass indicator or wind direction indicator where a reliable and accurate instrument
is prescribed.
The light intensity can be altered by means of a common dimmer for all instruments.
Dimming of an instrument can be done by means of a 1kΩpotentiometer.
2. Mounting instructions
DLQA96/144 is designed for installation in bridge consoles or switchboards.

The instrument is mounted by means of the 2 fixing elements. For instruments with
IP54 or IP66 protection, use all 4 fixing elements and the rubber gasket (included in
the packing).
3. Connection
DLQA96/144 instruments differ from the other DLQ instruments, as the DLQA96/144
instruments are based on an X-coil system and not on a moving-coil system like the
other instruments in the product programme of DEIF A/S. Due to the X-coil technology
it is possible to have an instrument with a scale curve of 360°, which is not possible in
the conventional moving-coil systems. As the X-coil system requires a special
controller integrated in the instrument, the DLQA96/144 instruments are to be
connected to an auxiliary supply – unlike conventional instruments. The plugs marked
PROG and COM are for factory use only.
Installation instructions, DLQA96/144
4189350016B (UK)
DLQA96/144 is protected against ESD (static electricity). Therefore, when connecting
the instrument, no special protection from ESD is needed.
When the instrument is mounted in the console/switchboard, the terminal on the rear
side is connected to the cable.
The instrument is configured either for “single input” or for “double input” – here it is
configured for connection to a SIN/COS converter.
Auxiliary supply: AUX 24V -/+
Illumination: ILLUM -/+
Input: INPUT B/GND/A (see the table for single/double input)
4. Adjustment and control
As the instrument is linearized to a max. indication error of 0.5% corresponding to a
max. deviation of ±1.8° over the entire scale curve of 360°, it is not provided with an
adjustment device. For control of deflection (indication) as a function of input the table
below can be applied.
