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 1kΩ potentiometer.
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.
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.
Response time: Max. pointer movement: 90°/second, no overshoot
Protection: IP52 from front, IP20 from back (terminals) according to IEC 529
and EN 60529
(IP54 from front is optional with special gasket)
or
IP66 option in special DLQW housing, IP20 from back (terminals)
according to IEC 529 and EN 60529
Climate: Class H U E, short term condensing allowed
Max. 95% RH: Max. 30 days per year
Max. 85% RH: Remaining days
Max. 75% RH: Average per year
According to DIN 40040

Temperature coefficient: Max. ±0.5% of full scale within -10…55°C
according to IEC 51 and EN 60051
Panel influence: Linearity is not affected by the panel (thickness or material)
according to IEC 51 and EN 60051
Shock: 18 x 50 g half sine (11mS) according to IEC 68-2-27. Test: Ea
Vibration: 3…13.2Hz: 2.0mm peak-peak (±1.0mm) according to GL + LR:
Test 1
13.2…100Hz: 0.7 g according to DNV: Class A

Consumption: <3W (24V/120mA), excl. illumination
EMC: CE marked for residential, commercial and light industry plus
industrial environment according to EN 50081-1/2 and EN 50082-
1/2
Class approval: Marine Equipment Directive 96/98/EC (MED)
Connections: Separate screw terminals for instrument input, power supply and
illumination
Max. 2.5mm² multi-stranded or 4.0mm² single-stranded
Materials: All outer materials are self-extinguishing according to UL94 (V0)
Illumination input: 24V DC. Adjustment range: 10...30V. Galvanically separated from
other circuits
Colour: Red and green light (LED based) combined giving a white/yellow
colour
Current consump.: DLQA96/144: 12mA/24V DC
Galv. separation: 500V – 50Hz – 1 min. between groups (3 groups)
If protection against voltage transients (surge pulse) for the auxiliary supply AUX 24V
-/+ and input for ILLUM -/+ is required, these inputs are to be protected externally. The
protection must be positioned no more than 10 m from the DLQA96/144 instrument
and must meet the requirements of the class and the legislation.
