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.
