CHAPTER 1: GETTING STARTED

The DL21 Doppler speed log is a Dual STW and SOG Navigational Doppler Speed log system.
The new DL21 Speed Log is designed for ships over 50.000 GT with simultaneous and independent
measurement of speed through water and speed over ground.
The DL21 is a DL1 ( single axis STW) + DL2 (Dual axis STW + SOG), built into 1 sensor housing,
1 electronic unit and 2 Display units.
The system fullls all class and type regulations based on MED B (wheelmark) and is manufactured
in Norway under stringent production controls.
The DL21 system consist of:
2 x Operator units.
• CU-M001-21-SB for DL2
• CD402CU-SC for DL1
1 x Dual Electronic Unit
JB70D21-SA Electronic unit

The operator unit is placed on the bridge.
Some standards require some operations of the unit to be available from ‘standing position’.
These operations are available from the operator unit and multi-repeaters if both input and output
are connected.
Dimensional drawings are found in Appendix 1.

The electronic unit can be installed on a DIN rail or directly screwed onto the wall.
All parts of the system are connected to the electronic unit.
There are no buttons (like ON/OFF) in the electronic unit. Access is only required for service purpose.
Placement is typically in or near the bridge where the interfaced systems are available, but no
nearer than 0.5 m to the GYRO heading sensor. IP rating: IP20.

Repeaters are typically installed on the overhead console and/or the bridge wings. These can be
routed using NMEA signals. These require a local +24 V DC supply. Please note that STW NMEA
output from DL1 part and SOG NMEA is from DL2 part.

Mounting instructions for the sea valve is available from the SKIPPER web site in separate manual
depending on the chosen type. When placing the speed log sensor, consider the following moments:
• Free sight to the bottom (it should be possible to draw a cone of +-45 degrees from the
sensor to the bottom).
• The active face of speed sensor must be in parallel to the horizontal line, max o󰀨set +-1°.
• Do not mount transducers aft of bow thruster, propeller outlets or aft of other hull
installations (such as outlets, vents or other protruding details) that may create aeration or
turbulence.
• It is necessary to select a part of the hull that is submerged and free from turbulence and
aeration under all load and speed conditions, and to avoid positions where air is trapped in
heavy weather.
• If a at, horizontal section is not available for transducer tting, the shipyard must construct
a suitable bed. Welding seams in this area and forward should be smoothed and rounded
o󰀨 in order not to create turbulence or aeration and maintain a laminar waterow at all
speed ranges of the vessel.
• Select an area that is acoustically quiet. The DL2 operates at frequencies between 270 kHz
and 284 kHz. The DL1 between 710-720kHz.
There are 4 acoustic channels in DL21
DL1 has 2 channels(Blue forward and blue aft)
DL2 has 2 channels (Brown forward and Green starboard).
The acoustic signal is sent in a 30deg angle from vertical.
A tilt sensor internally inside the DL21SG-SA sensor is used to
compensate for vessel movement.

Page 14 of 61 2021-03-22
Installation DL21 Doppler Speed Log System
The generally best placement on larger vessels is in the front region of the vessel just behind the
bulbous bow (see g above). This area is generally designed such that the bubbles are pushed to
either side of the bulb, leaving a clear area under the bulb and just behind. The sensor is installed in
a sea valve in order to service the sensor (clean or replace) without docking the vessel.
It is recommended (but not required) to install the sea valve in a dry area, like a bow thruster room.
This will enable easy cable access to junction box and additionally increase the lifetime of the sea
valve.
The sensor DL21 is installed into sea valve
100mm for single bottom SB-100-SB or
double bottom DB-100-SB.
Please see sea valve manual for installation
procedure.
Manuals available as downloads from
www.skipper.no
The sensor includes 40m moulded in cable.
The cable is 11 mm in outer diameter with a
bending radius of 56 mm. The cable can be
cut or extended if required

NOTE
During physical installation of sensor into sea valve please make special care of the following points:
• Sensor to be lowered completly into bottom ange making sensor head ush with outer hull.
• Sensor forward direction to be aligned +/-10deg. (Fine adjust by software in calibration page)
• Clamping unit nuts and nut M50 to be tighten to secure sensor position.

CHAPTER 3: WIRING
Two separate 24VDC supplies are required
The JB70D21-21-SA does not contain a physical switch and should be connected to a circuit breaker.
Power may be nominal 24V DC (No more than 32V DC) and/or 115-220V AC. Max 60W typical 15W.
The AC input is an optional back up for DL2 part of JB70D21-SA only.
There are no input fuse on the CU-M001-21-SB or JB70D21-SA.
The power input should be including a fuse rated for 100% - 200% of max power installed components.
Example: A 24V DC to power both CU-M001-21-SB and JB70D21-SA should have a 3A slow blow
fuse.

Cables should be connected to WAGO connector, leaving
approximately 3 cm of tail. They should be stripped with 6-7 mm of
metal showing and these should be connected as in the diagram
above. A small screwdriver with blade size approx 3.5 mm can be
used. WAGO part no 210-719 is ideal for this use.
Outer shields should be collected and grounded in a ground stud on
the edge of the cabinet. The outer insulation should be cable tied to
the plastic handle of the connector, and securely anchored nearby.
The plugs when retted, must be installed such that their clips are
fully in the up position.
