Introduction
FURUNO Electric Company thanks you for
considering and purchasing the TS-331A
Wired Trawl Sonar. We are confident you
will discover why the FURUNO name has
become synonymous with qualit y and
reliability.
The TS-331A is a wired trawl monitoring
system designed to improve control and
efficiency in pelagic and semi-bottom
trawling. Mainly consisting of an
Underwater Unit, a Surface Processor Unit
and a Mouse, the TS-331A presents data
received from a trawl-mounted transducer
on high quality and low-noise images.
No machine can perform to the utmost of its
ability unless properly installed, maintained
and operated. Please read and follow the
recommended procedures for operation
and maintenance to get the most out of the
equipment.
Features
The TS-331A is a third wire, head rope
mounted system incorporating a high
resolution scanning sonar designed
especially for monitoring the opening of the
trawl net and surrounding areas. Also
included are depth and tem perature
sensors, a 120kHz downward looking echo
sounder, four catch indicators, and a pitch
and roll indicator for monitoring the attitude
of the trawl unit. The trawl unit is connected
to the Surface Processor Unit by a
2-conductor cable. This cable provides 130
VDC power to the trawl unit as well as
two-way communications.
Some of the main features are
• High resolution net profile
• Graphic presentation of net attitude
• Three display modes: polar (0°-360°),
locked (echo sounder) and sector (0°180°)
• Four catch sensors (option) may be
mounted on the codend to monitor cat ch.

1. OPERATIONAL OVERVIEW
1.1 Surface Processor Unit
The Surface Processor Unit (sometimes referred to as “Processor”) has a built-in
PC mother board, Windows XP
least 2GB disk space. The system provides a control and display application
TS331A.exe (installed on the Processor), which is a very convenient tool for
users to control system parameters such as acoustic operating range, scan
speed, scan area, etc. It also displays real-tim e data such as depth/temperature,
vertical sonar images, echo sounder images, pitch and roll, and catch sensor
information on the screen in resizable windo ws .
The mouse connects at the rear of the Processor and funct ions t o control the
system, from various menus. Note that the system can also be controlled from a
keyboard (local supply).

1.2 Underwater Unit
1.2.1 Components of the underwater unit
The underwater unit mainly consists of a red polyurethane case and three
transducers. The vertical sonar transducer is the cylindrical red housing which
extends from the back of the case. The (gray) echo sounder transducer is
mounted near the front of the unit. The catch sensor receiver transducer is
located at the back of the unit, to the right of the vertical sonar transducer.

1. OPERATIONAL OVERVIEW
1.2.3 Mounting the underwater unit on the trawl
Usually the underwater unit is fixed either on the head rope of the trawl or on the
belly just above the ground rope.
The advantage of the former position is that the underwater unit is held
horizontal almost throughout the towing operation and consequently a good,
stable image can be expected. Its disadvantage is that it is difficult to detect the
ground rope, especially in bottom trawling since the ground rope in the bottom
trawl becomes positioned farther back than the head rope. In mid-water and
pelagic trawls, the ground rope usually becomes positioned below the head rope
and hence the ground rope is easily detected with the underwater unit on the
head rope.
The underwater unit is typically enclosed in a “pouch” made of fine mesh netting
and attached to the head rope with ropes. The pouch is attached to a small
mesh net (smaller trawlers) with ropes to stabilize the underwater unit. (Smaller
trawlers may not require the small mesh net for stabilization.) The small mesh
net is attached to the trawl with ropes.

If the ground rope is positioned in the coverage area of the sounding beam it is
displayed as a line almost parallel with the transmission line. If a fish school
appears between the transmission line and the ground rope it can be considered
to be entering the trawl.
The interval between the transmission line and the ground rope is equivalent to
the height of the trawl opening and therefore the interval is kept constant if the
trawl is being properly towed. If it is unsteady, or if the ground rope rises
suddenly, towards the transmission line, the trawl may be caught on some
object.

1. The trawl is set into water and begins descending. In the image, the distance
between the transducer and the bottom gets shorter and shorter as if the
bottom is rising toward the transmitter unit. On the other hand, the distance
between the transducer and the sea surface increases as if the sea surface
is receding from the transducer. The range has been changed twice for
shorter ranges.

2. The trawl has settled on the bottom.
3. The trawl is being towed along the bottom. Fish entering the trawl are seen
above the ground rope. The ground rope is being kept at a constant distance
from the transducer, indicating that the trawl mouth is opening properly in the
course of towing.
2. SONAR OPERATION
4. The ship has accelerated to clear a shoal. The trawl is rising off the bottom
and the bottom is displayed as if it has a sharp undulation though it actually
does not.
5. The trawl is passing over the shoal. The ground rope seen off the bottom
indicates that the shoal has been cleared.
6. The trawl has settled on the bottom again.
7. The trawl is being towed along the bottom.
8. Hauling of the trawl has begun.

6. CATCH SENSOR OPERATION
6.1 Catch Sensor Dialog Box
The Catch Sensor Setup dialog box provides a tool for you to configure the
catch sensors on a trawl net. You can install up to four catch sensors on the
TS-331A system. TS-331A program default settings display four catch sensors.
You can click the Delete button in this dialog box to remove catch
sensor/sensors if less than 4 catch sensors are installed.
Catch sensor setup dialog box
The Catch Sensor Setup dialog box provides the following options:
Enable catch sensor (check boxes)
Checking/Unchecking the “Enable Catch Sensor” check box will enable/disable
that particular catch sensor. There can be a maximum of four catch sensors
installed at a time.
Catch Sensor ID (edit boxes)
The Catch Sensor ID is a number used to distinguish different catch sensors.
Each sensor transmits an acoustic signal with its own fixed frequencies so the
system knows which one is installed (received a standby signal) or triggered
(received a triggered signal). TS-331A uses number 1 to 4 to distinguish them.
1: 69.75kHz/70.25kHz ±50Hz
2: 72.25kHz/72.75kHz ±50Hz
3: 74.75kHz/75.25kHz ±50Hz
4: 77.25kHz/77.75kHz ±50Hz
It is not required to install the sensor number 1 at the first position (Pos1), sensor
number 2 at the Pos2, etc. You may install sensor number 1 at Pos4, for
example. In this case, you need to input the right numbers of the sensor ID at
the corresponding position.

After changes are made and accepted, by clicking the “OK” button, the catch
sensor display will adjust to those changes.
6.2 Catch Sensor Window
The catch sensor window is located below the pitch/roll window and it indicates
catch sensor status and sensor activation time.
The program has an internal timer which counts sensor activation time. If the
trigger (indicated by showing red in a sensor status window) is present for two
minutes, the timer starts counting. This two-minute gap between trigger
presence and timer start is done to prevent false readings. After another minute
has passed, the indicator will show "00:01" and will update once every minute.
The timer continues to count even if the signal goes away (for example, the
catch sensor points in wrong direction). This is shown on the catch sensor
window by displaying a time, but no color (red or yellow) is seen in the catch
window. You may reset the timer by left-clicking Reset Catch Sensors in the
Options menu.

6.3 Testing for Switch Activation
To test for proper switch activation, do the following:
1. Submerge the unit in SALT
2. Wait for about 20 seconds, then pull the lanyard for a few seconds and let go.
The LED should flash 13 seconds after the lanyard was pulled. This is the catch
frequency. 13 seconds after the first flash it will flash again. This is the active
frequency.
water or short the electrode and trigger bolt.
6.4 Flashing LED Sequence
This paragraph describes the LED sequences for the catch sensor.
1. When the batteries are first installed in the unit, the LED will flash, after a
10-second delay, 15 times. This merely indicates that there is power to the
CPU and it is running.
2. When the unit is submerged (or the electrode and trigger bolt are shorted for
test purposes), the LED will flash four times. This means the unit is in water.
3. After a delay of two seconds, the LED will flash once for every 100 hours that
the unit has been in water without removing the batteries. If the unit has been
operated for under 100 hours it will not flash.
6. CATCH SENSOR OPERATION
Note: If the battery cap is removed, the 100 hour counter will reset.
4. About 11 seconds after step 3 has been completed, the LED will flash once.
This is when the unit is actually transmitting. If the unit is kept in water, the
LED will flash every 90 seconds. (The flash indicates transmission.)
Step 4 only occurs the first time the unit is activated with new batteries. After the
first time, whenever the unit is activated (via a jumper or submerged) only steps
2 and 3 occur.
6.5 Catch Sensor Transmission Frequency
The transmission frequency of the catch sensor(s) can be changed, by a
qualified technician. For further details, contact a FURUNO agent or dealer.

5. If the vertical scanning and echo sounder images update properly and depth
and temperature readouts show 0 m and ambient temperature respectively,
the underwater unit is functioning normally.
Note: If echo test is required, immerse the underwater unit in water (fresh or
salt water) and check for echoes.
6. Turn off the Surface Processor Unit and monitor.
7. Disconnect the test cable and then fasten the connector.
8. Spray the connector with silicone spray.
9. Close the cover. Do not overtighten screws; the case will crack if screws are
overtightened.

7.5 Troubleshooting
The table below provides simple troubleshooting procedures which the operator
may follow to restore normal operation. If normal operation cannot be restored,
do not attempt to check inside the equipment. There are no user-serviceable
parts inside. Refer any repair work to a qualified technician.
If… Then… Remedy
the image is not updated
image color is abnormal
noise or interference
appears on the screen
the image undulates (in
case of CRT monitor)
the “HOLD” feature may
have been activated.
(“HELD” appears at the
top-left corner on the sonar
display.)
image brilliance may be
improperly set.
• gain setting may be too
high.
• poor ground may be the
cause.
• cables of other equipment may be too close
to the Surface Processor
Unit.
• suspect noise problem.
a magnetic field-generating
device (rectifier,
transformer, etc.) may be
too close to the monitor.
Troubleshooting
Click the HELD button on
the settings dialog box to
release the hold feature.
Adjust image brilliance
from the monitor.
• Check if the gain
setting is too high.
• Check ground.
• Separate cables.
• Check cable, winch,
slip ring by using test
cable.
Check for offending
device by turning off all
equipment and then
turning them on and off
one by one. Increase the
distance between
offending equipment and
the Surface Processor
Unit.

7.6.2 Diagnostic test description
Header: Sent by the sonar system (wet end) to tell the Processor what kind of
data format it sent, IGX for image data and ITX for normal digital data.
Data Type: (same as Run-Type) sent by the sonar system (wet end) to tell the
processor this set of data is coming from which sensor.
Serial Stat: indicates if the communication between sonar system and
Processor is normal or not.
Head Pos: (Head Position) a number sent by the sonar system to tell the
Processor vertical sonar shooting direction. Valid number: 100-1300 (an angle
between 0 to 360 degrees).
Head Dir: A value indicates vertical sonar scan direction: 0 for counter clockwise,
1 for clockwise.
Range: Vertical sonar and echo sounder operating range. The operating range
for vertical sonar is 10m to250m. The operating range for echo sounder is 50m
to300m.
Sync Val: a number that represents the level of the SYNC pulse from the sonar
head and echo sounder/Catch Sensor for every shot (approximately 800).
Data Bytes: how many bytes the sonar system sent to the Processor for each
shot.
PRF: milliseconds elapsed between the two consecutive interrogations for a
sensor. Usually the system interrogates the Echo Sounder every second and
Pitch/Roll data every 5 seconds.
Temp Val: temperature value sent by the sonar system (coded).
Temp: Decoded current temperature reading in Celsius or Fahrenheit units.
Depth Val: Depth value sent by the sonar system (coded).
PSI: a number sent by the sonar system to indicate the type of pressure sensor
installed in the system. 0: 1000 PSI, maximum displayed depth 686 meters. 1:
3000 PSI, maximum displayed depth 2059 meters.
Depth: Decoded current depth reading.
Pitch: Decoded pitch value.
Roll: Decoded roll value.
CH1, CH2, CH3, CH4: four catch sensor channels. 0: channel (sensor) disabled
or not receive any signal from this channel, 1: received stand by signal from this
channel, 2: catch sensor triggered.
