Introduction

INTRODUCTION

The Simrad PI54 is an integration of proven commercial fishing technologies which can dramatically increase the yield and effectiveness of purse/danish seining and bottom/pelagic trawling applications.

By means of six underwater sensors mounted on the gear, this robust, maintenance-free catch monitoring system allows unparalleled control over fishing operations by providing continuous, centralised information on the vessel’s position, its gear and the environment at and below the surface.

This manual is not intended to be read from cover to cover, but is designed as a book of references that you can consult whenever necessary.

This manual describes PI54 software version 0.40.

System description

SYSTEM DESCRIPTION

The Simrad PI54 catch monitoring system consists of an operator station, a hydrophone and an optional echo sounder transducer. The hydrophone and the transducer are both mounted under the vessel’s hull. The system further comprises a number of small and robust sensors measuring the conditions on your fishing gear.

The PI54 catch monitoring system can work with six sensors simultanously.

The sensors are powered by built-in rechargeable batteries. They are housed in titanium casings, and designed using advanced shock absorbing materials. The information collected by the sensors are sent through the water to the hydrophone by means of coded sound waves. From the hydrophone, the signals are sent to the operator unit, which decodes the information, interprets it, and finally present it to you.

Hull mounted and portable hydrophones

Two hull mounted hydrophones are available, one for purse seining operations, and one for trawl operations. You can install both, and then select active hydrophone by means of a selector box on the bulkhead.

Purse seining: The hull mounted hydrophone for purse seining operations has a 90 degrees horizontal beam and a

30 degrees vertical beam to provide the

PI54 with optimal reception from the sensors. This specific beam pattern is especially suited for purse seining and the wide coverage area reduces the need for careful alignment.

Trawling: The hull mounted hydrophone for trawling operations has a 50 degrees horizontal beam and a 30degrees vertical beam to provide the PI54 with optimal reception from the sensors. This specific beam pattern is especially suited for trawling and the wide coverage area reduces the need for careful alignment.

Portable: A portable hydrophone is also available. It is designed as a temporary measure until a fixed hydrophone can be installed at the vessel’s next planned dry docking. It has an omni-directional beam and a 50 meter integrated cable which is sheathed in polyurethane providing robust external protection to compliment its 150 kg tensile strength. The cable is supplied on a reel for convenient retrieval and stowage, and is equipped with a plug for easy attachment to the Operator Unit.

Sensor overview

This chapter provides a very short description of each sensor.

• Depth sensor - The Depth sensor provide information about the current depth as well as the descending or ascending rate related to the surface.

• Catch sensor - The Catch sensor provides information about the amount of catch in the trawl. The sensor monitors the opening of the meshes in the cod-end, and will activate once the caught volume pulls the detector wire. To monitor the filling rate, you are adviced to use minimum two sensors.

• Bottom Contact sensor - The Bottom Contact sensors detects if a trawl is accidentally lifted off the seabed, or a purse seine is touching the bottom.

• Rip sensor - The Rip sensor provides an immediate warning when the net is ripped.

• Temperature sensor - Temperature sensors read and transmit the ambient water temperature at the gear depth.

• Height sensor - The Height sensor contains s small echo sounder to measure the current depth related to the seabed.

• Spread & Remote sensor - These sensor always work in pairs, and they measure the distance betwen the trawl doors.

You can also use two Remote sensors if you run a twin trawl.

The use of separate communication channels for the individual sensors allows you to use your sensors in the vincinity of other vessels using PI or PS sensors. The communication channels can be defined and/or changed onboard your vessel using a standard computer and the PI Configurator utility.

Battery chargers

All sensors are power by internal batteries, and these need charging at regular intervals. The Simrad chargers have been designed to allow the sensors to be stored in charging positions whenever they are not used, and “overcharging” will not take place. Either of the two charger types can be used on any of the sensors, but the PI Charger will only provide fast charging on the PI Sensors.

PS30 Charger

Three different Simrad PS30 Chargers are available depending on the vessel’s main power supply; 230 Vac, 110 Vac and +24 Vdc.

PI Charger

The PI Charger will provide fast charging of the new PI sensor series. The Simrad PI Charger requires a +12 to +32 Vdc power supply.

Simrad PI54

Introducing the sensors

The PI54 catch monitoring can be used with a variety of sensors. All these sensors can be placed on your trawl or purse seine to monitor key parameters.

On the PI54, you can use maximum six sensors simultanously.

There are two sensor families; PI and PS. The sensors in the two families are almost identical, and they can be used together on the same PI54 system. The PI sensors will however offer increased range, some added functionality, and they can also be charged much faster using the PI Charger.

Bottom Contact: Best at the bottom!

With patented technology and awardwinning design, Simrad provides you full control of the actions that take place at the bottom. Mounted on a bottom trawl, pelagic trawl or purse seine, this sensor will provide the important information when you need it!

20

(A) = The Bottom Contact sensor mounted on a bottom trawl will let you know once the trawl lifts a few centimeters above the bottom. You can then immediatley perform the necessary adjustments, and you will not loose any catch.

(B) = On a purse seine you will be notified once the seine reaches the bottom, and you can thus fish even on a rough bottom.

(C) = On a pelagic trawl, the sensor will notify you once you get near the bottom.

The Bottom Contact sensor will let you know immediately if your gear touches the bottom.

• Bottow trawl: If your trawl lifts off the bottom, this may cause fish to escape, and hence reduce the catch. This sensor will detect this, and allow you to trim your equipment for perfect balance.

850-165186 / Rev.B

Getting started

850-165186 / Rev.B

• Pelagic trawl: On a pelagic trawl, this sensor proves very useful when the trawl moves downwards. It will let you know immediately if the footrope touches bottom.

• Purse seine: When you work with a purse seine, you need to know when the seine reaches the bottom. This sensor will let you know. once it happens.

• Danish seine: Used on a Danish seine, the sensor will let you know when the net has a stable bottom contact, and when it is time to haul.

• Scientific research: During scientific surveys, an exact definition of towed distance with proper ground gear contact is an essential parameter in bottom trawl swept area estimates of fish abundance. Using a Bottom Contact sensor will reduce errors in this key parameter.

Catch sensor: When is the trawl full?

This is your “eye” at the cod-end. With PI Catch sensors in use, you can easily monitor the fi lling rate and the amount of catch in the trawl. Save time and fuel, haul in the trawl at the right moment! The design is rugged and awardwinning, and the sensor’s sensitivity is easily adjustable for trawls of all sizes.

Some professionals claim that the Catch sensor is the most important sensor on the trawl. Why? Because it will tell you the amount of catch in the trawl.

The sensor simply monitors the expansion of the meshes in the cod-end. Once the volume caught is enough to expand the meshes, they will pull the detector wires and engage the sensor.

The sensitivity of the sensor can easily be adjusted, just extend the detection rubber bands to span additional meshes.

To monitor the filling rate, we recommend that you use minimum two sensors. Place the first sensor at the far end of the cod-end, it will tell you that the trawl is actually fishing. Place the second sensor closer to the trawl opening. Once the trawl is filled to the chosen location, the sensor is engaged, and you know that it is time to haul.

Use the PI Catch sensor to adjust the catch volume according to the production capacity, check that the trawl is fishing, adjust the caught volume to secure quality, and minimize the towing time to save fuel. These are only a few of the reasons why this sensor is considered to be so important.

21

Simrad PI54

22

Depth: How deep can you go?

When the sonar and echo sounder tell you how deep the school goes, it is good to know that you can place your fishing gear at the same depth. And even better, you can monitor and hold the desired depth. The design is rugged and awardwinning, and the sensor is available for three different depth ranges.

The PI Depth sensor provides information about the current depth and the depth changes of your gear.

• Bottom trawl: On a bottom trawl, you will use the sensor to achieve full control when shooting, and to position the trawl on the slope.

• Pelagic trawl: During pelagic trawling, you know how important it is to position the trawl relative to the largest concentration of fish. By using a Depth sensor, you can monitor the exact depth relative to the surface, and adjust the trawl depth accordingly. Additional depth sensors on the doors will monitor if the doors stay at the same depth.

• Purse seine: During seining, use the Depth sensor to monitor the depth of the net, and the descending speed of the net.

Then you will know when to start pursing, and which speed to use.

• Danish seine: Mounted on a Danish Seine the Depth sensor monitors the sinking speed of the net, and it will tell you when to start hauling once the net has stopped sinking.

Height sensor: Accurate distance to the bottom!

With a built-in echo sounder, this new PI sensor is full of advanced technology. Wherever you place it, it will always tell you the exact distance to the bottom.

The height sensor measures the height over the bottom, that is the distance from the bottom and up to wherever the sensor is located. This provides you with a valuable range of applications for bottom and pelagic trawling.

• Bottom trawl: Place the sensor behind the headrope, and it will tell you the height of the trawl opening. This allows you to adjust you equipment immediately if the opening is reduced, and you will avoid loosing catch.

• Pelagic trawl: With a height sensor behind the footrope you will know at once if the trawl approaches the bottom. If you use a second sensor behind the headrope, the difference between the two measurements will give you the height of the trawl opening.

850-165186 / Rev.B

850-165186 / Rev.B

Getting started

Rip: Check for damages!

The Rip sensor is identical to the Catch sensor, and can thus be regarded as a application for the Catch sensor. Place the sensor on the trawl belly behind the footrope, and use it to detect if the trawl is torn or in any other ways damaged by rocks or other roughness on the bottom. If this is detected immediately you can adjust the gear to minimise the damage.

Spread and Remote: Check the trawl doors!

This dynamic duo tells you the exact distance between the trawl doors. Used on bottom and pelagic trawls the Spread and

Remote sensors provide crucial information about your trawl behaviour. On a twin trawl, simply add a Remote sensor and you have both openings covered!

These two sensors always work in pairs. They are used to monitor the physical distance between the trawl doors during bottom and pelagic trawling.

Use a Spread sensor on the port door and a Remote sensor on the starboard door. Both sensors are normally mounted in special adapters, but you may also attached them to the wing-end or warp using snap hooks or rope.

The Spread sensor communicates with the Remote sensor using a special transverse communication link. By means of this link it measures the excact distance (maximum 350 meters) between the two sensors. The information is is transmitted to the vessel by the Spread sensor.

As you already know, correct door spread is important in order to obtain the correct sweep-angle, as this ensures optimal trawl performance. Door behavior and stability during shooting and towing is also monitored by these sensors. Many regard this pair of sensors one of the most important sensors to obtain efficient trawling.

A special version of the PI Spread sensor, The PI Twin Spread, allows you to use a single Spread sensor with two Remote sensors to monitor a twin trawl.

Temperature: Too warm or too cold water?

Fishing in too warm or too cold water may be just a waste of time and money. The same applies to a pelagic trawl placed on the wrong side of a thermal layer. Using advanced technology, rugged construction and awardwinning design, the PI

Temperature sensor allows you to increase your fishing efficiency.

The PI Temperature sensor tells you the exact sea water temperature while you are fishing.

23

Simrad PI54

The water temperature is an important parameter. Fish and bait are temperature sensitive, and they are normally found within specific temperature zones for feeding and spawning.

However, the temperature layers in the water are changing constantly, and for this reason the temperature must be monitored constantly. Fishing in an area with unfavourable water temperature might be just a waste of time!

For any kind of trawling, use this sensor to monitoring and log the temperature. Then, increase your knowledge about the correlation between temperature, fish concentration and catch efficiency. On a purse seine net, monitor the temperature to see when you are passing the thermo-cline.

The following operational modes are available

• Standard mode: Range start is fixed, and the depth range can be altered

• Phased range mode: The range start can be adjusted, and the current value is added to the depth range

• Bottom lock: The echo sounder provides an expansion window to study the echoes closest to the bottom.

• Zoom: The echo sounder provides an expansion window to study echoes in the water column.

• A-scope: Single ping echo presentation

(D) = Gain indicators for the current sensors

(E) = Lower status field

(A) Numeric information

The numeric displays at the top of the Status display provide the current information from the active sensors. Due to the lack of space, the information from the sensors have been abbreviated slightly. For a more detailed presentation, you must select the the Numeric display presentation.

(B) Upper status field

The upper status field provides an overview of key parameters.

Receiver setup: All the parameters on the left side are those defined by the Receiver setup dialogue. To change these, press the MENU button to access the Setup menu (4), and select

Receiver setup (6).

SW: This sentence provides the current software version in your

PI54 system. Main is the operational software providing the user interface, µC is the PI54 microcontroller, while DSP is the software controlling the digital signal processor, that is the reception and interpretation of sensor information.

Max sh. speed: This is the maximum shooting speed as defined in the Receiver setup dialogue.

Demo: This entry shows you if the sensor demonstration mode has been activated. To switch the Demo mode on or off, access the Sensor setup.

Last received ch: This entry shows you which of the sensors that last provided information to the PI54.

Error: This is simply an error code. This information is provided for test purposes only. Unless a software error occurrs, the code will be 0 (zero).

Hydrophone: A yellow indicator is provided when the hydrophone is connected and fully operational. If the indicator is red, a short circuit has occurred. If the indicator is black, the

PI54 has lost electrical contact with the hydrophone.

NMEA1/2: Any information accepted by the NMEA interface will provide a green indicator. If the indicator is black, the PI54 is currently not receiving input traffic, however, information may still be exported continuosly.

Simrad PI54

(C) Frequency spectrum

This graph provides you with information about the background noise and the signal strength of the frequency band or channel number selected. Each vertical bar represents the background noise for the given frequency or channel, and the level is measured continuously.

To select spectrum display, press the ADJ button to open the

Status setup dialogue, and select Spectrum, display to show

Frequency or Channel. In most cases a Channel view will be most useful to you.

This function is very useful if you have too much noise and this makes the communication with the sensor unreliable. Switch off as much electrical, mechanical and acoustic gear and equipment as possible. Then, switch the systems on again one by one while keeping an eye on the frequency spectrum. When the “noisy” system is activated, it is most likely easy to see!

Note that the frequency spectrum presentation depends on the

Interference filter setting.

(D) Gain indicators

There are six gain indicators, one for each of the current sensors. At the top of each indicator you can see sensor number and sensor type, at the bottom you can see the sensor’s communication channel and current update rate.Green colour indicates that the reception of signals and noise is within normal specifications. Red colour indicates that the received signal exceeds the minimum level required for reception, this is therefore not an error message.

For the technical minded: When no sensors have been deployed, the indicators will present the mean noise level. This is the noise in the surrounding water, caused by mechanical, electrical, acoustic and natural disturbances. This noise level should be as low as possible. When a sensor in the water transmits its information back to the PI54, this is indicated as the green indicator extends above the mean noise level. In order for the reception circuitry to accept and recognize the signal, it must be stronger than a predefined minimum level. The level is normally referred to as the detection level. If the signal is stronger than the detection level, the indicator bar will change colour to red.

The very first time you switch on the PI54, you will need to set up the sensor configuration. This will also be required if you perform a “master reset” on the PI54, and then reload the manufacturer’s default settings.

Observe the following procedure to establish the most common values. For more detailed information about the settings, refer to the References chapter.

In order to establish the sensor configuration, you need to know what kind of sensors you have, which channels they communicate on, and how often they communicate. This information is required before you start the configuration on the

PI54.

Do not attempt to set up the sensors unless this is absolutely necessary.

We strongly suggest that you use the forms in the front of this manual to write down the sensor you have with information about their update rates and communication channels.


2 Open the Setup menu (4), and select Sensor setup (5).

3 Press the ENT key to bypass the warning page.

4 For each of the sensors you shall use, select the following parameters:

a Set Sensor type to SINGLE to activate the sensor.

b Set Update rate FAST, SLOW or NORMAL

c Set Measure to chosen sensor type.

d Set Channel to correct communication channel for the chosen sensor.

5 For operational use, make sure that Demo mode is set to

OFF.

6 When you have defined the sensors, press the ENT buttom to save the changes and exit.

If you configure less then six sensors, you will be able to set the

Sensor parameter to Dual. You can not use this setting. Dual sensors are not yet available, and this functionality is not yet supported by the digital signal processing in the PI54. The ability to choose Dual is implemented for future expansion only, and any attempt to choose this setting will not work.

Predefined settings

Each sensor is delivered with a predefined setup. This setup includes:

• transmission channel for the acoustic communication link between the sensor and the vessel’s hydrophone

• update rate; how often the sensor sends its readings back to the PI54 system.

To change the sensor setup, you can call your local Simrad dealer, or you can do it yourself if you have the proper equipment, training and the PI Configurator software.

Changing a transmission channel

It may be required to change one or more transmission channels, and there may be many reasons for this.

• You have more than one of each sensor. For example, if you have three temperature sensors, they MUST communicate on three different channels.

• Other vessels near your use the same PI54 system (or a similar), and they have one or more of their sensors set up to the same communication channels as you have. This will create interference, as you will “read” each others sensors.

• If your sensors are set up to use communication channels too close to each other (for example, you have chosen channels

4, 5 and 6), this will limit the vessel’s speed. The reason for this is the doppler effect. If the speed is too high, the doppler will cause the transmission frequencies to change so much that they overlap, and this will create interference. The PI54 will provide a warning if this is about to happen! You must then either change to other communication channels further apart, or reduce the maximum shooting speed.

• If you operate at the maximum range of the sensors, you may be able to increase this range slightly if you use lower communication channels. This is because the lower communication channels user lower transmission frequencies.

Changing the update rate

It may be required to change the update rate on a sensor, that is how often it sends information back to the PI54 system. A high update rate will give frequent information updates, but the sensor will use more battery power. If you need your batteries to last as long as possible, you must consider lowering the update rate.

59

Simrad PI54

• A low update rate will provide you with fewer information updates, but the battery will last very long.

• A high update rate will give you frequent information updates, but the battery will run out faster.

All sensors are provided from Simrad with a default update rate setting. In some cases you may find that this update rate does not suit your operational needs. This is a decision you have to make depending on the local fishing conditions.

How to replace the sacrificial water switch

All PI and PS sensors are equipped with a water switch, and two different types are used. If your sensors are equipped with a brass screw, observe the following procedure for replacement.

1 Turn the sensor upside down, and locate the brass screw.

2 Inspect the screw for wear and tear. If required, replace the screw.

A standard commercial brass screw is used. Local supply will normally be available, but the following specifications must be met:

Brass, Size M5x10, DIN85A, rounded head

850-165186 / Rev.B

Before a new screw is inserted, Aqua Shield (or a similar underwater lubricant) must be applied. Due to the size of the tube, we recommend that the grease is applied from a syringe.

1 Apply Aqua Shield to the screw threads.

2 Insert the screw, mount firmly, but not too hard.

3 Use maximum torque 1.5 NM

A pack with ten screws and a tube of Aqua Shield can be ordered from Simrad as a spare parts kit.

Aqua Shield is manufactured by D.A.Stuart, Warrenville,

Illinois, USA (www.d-a-stuart.com).

How to calibrate the Depth sensor

Only the Depth sensor can be calibrated. The purpose is to ensure that the depth reported by the sensor is as accurate as possible.

This procedure is carried out onboard the vessel.

1 Mount a rope to the top fastening lugs on the sensor.

2 Tighten the rope, and measure one meter from the bottom of the sensor to a spot on the rope. Place a visual marker on the rope at that location.

3 Lower the sensor over the side of the vessel and into the water. Lower it until the visual marker on the rope is even with the surface.

4 On the PI54, observe the numerical presentation of the sensor, and allow the reading to stabilize itself.

5 On the PI54, press the MENU button to open the Main

menu.

6 Press 4 to open the Setup menu, and 4 again to open the

Sensor alarm/calibration dialogue.

7 Press the GAIN+ button three -3- times to access the

Depth calibration dialogue.

8 Set Depth sensor calibration to YES.

9 Press the ENT button to accept the choice, and one more time to acknowledge.

10 Observe the information page. Press the ENT button once again to proceed.

11 Leave the sensor hanging from the rope for minimum two minutes. Meanwhile, observe that the numerical presentation shows grey characters only.

12 On the PI54, observe that the numerical presentation of the Depth sensor is stable, and shows 1 meter.

13 Retrieve the sensor from the water.

In order to calibrate the sensor, it must be submerged in salt water.

You may wish to use a different depth reference than the sea surface. If this is the case, change the marking on the rope to fit you preference, for example the depth of the keel or the depth of an echo sounder transducer.

→ Depth calibration, setup, page 176

65

Simrad PI54

Note:

How to define sensor offsets

Only the Depth and Spread sensors can have their offset values adjusted. The purpose is to allow you to compensate for known deviations.

You may wish to insert a Depth sensor offset to line up the depth readings from the sensor with those from your echo sounder. If the echo sounder transducer is located X meters below the surface, the Depth sensor should have the same offset value.

If you have performed a Depth sensor calibration, you will see than an offset value may already be present. This value has been provided by the calibration routine.

1 On the PI54, press the MENU button to open the main menu.

2 Press 4 to open the Setup menu, and 4 again to open the

Sensor alarm/calibration dialogue.

3 Press the GAIN+ button four -4- times to access the

How to set up a Twin Spread sensor for twin trawl applications

By means of the Twin Spread sensor, you can set up your PI54 to monitor the openings on a twin trawl. Apart from the Twin

Spread sensor, you will also need two Remote sensors.

Sensor configuration

The Twin Spread and Remote sensors are supplied in sets, and they MUST operate in these sets. The sets are:

• Twin Spread 1 uses two Remote sensors; Remote 1 and

Remote 3.


Remote 4.

When supplied from the manufacturer, all Twin Spread sensors are set up as Twin Spread 1. If you wish to use a Twin Spread 2, your dealer (or yourself) must reconfigure the sensor using the

PI Configurator application.

Communication channels and update rate

Each Twin Spread sensor will communicate on two channels, one for each of the two distances the sensor measures. By default, these communication channels are set to 02 and 07.

• Channel 02 is used to measure the distance to Remote 1.

• Channel 07 is used to measure the distance to Remote 3.

By default, both communication channels are set up with Fast update rate. In order to increase the lifetime between each sensor charging, you may consider changing to Normal update rate.

If you wish to reconfigure the settings, your dealer (or yourself) must use the PI Configurator application.

Placing the sensors on the trawl

The Twin Spread sensor must be mounted on the port trawl door, and the three communication transducers on the sensor must not be obstructed. Ensure that you have a clear line of sight between the tip of the Twin Spread sensor and the vessel, and between the Twin Spread sensor and the two Remote sensors.

Remote 1 is placed on the centre clump.

Remote 3 is placed on the starboard door.

67

Simrad PI54

This configuration will allow the Twin Spread sensor to measure the distance from the port door to the centre clump directly. It will also measure the distance between the two trawl doors. In order to calculate the distance between the centre clump and the starboard door, you must perform the required settings on the

PI54.

68

(P) = Port trawl

(S) = Starboard trawl

(C) = Port trawl door with the Twin Spread 1 sensor mounted.

Sensor setup

Observe the procedure below to set up a Twin Spread configuration with its default settings.

In this procedure, sensors 1 and 2 are used, and no other sensors are shown. Due to the fact that the Twin Spread sensor occupy two communication channels, the setup program requires that it is configured as if it was two separate sensors, but not necessarily sensors 1 and 2. The remaining four channels can be used for other sensors.

The Twin Spread and Remote sensors are supplied in sets, and they MUST operate in these sets. The sets are:


Remote 3.


Remote 4.

When supplied from the manufacturer, all Twin Spread sensors are set up as Twin Spread 1. You will now need to use Twin

Spread 2 as well, and your dealer (or yourself) must reconfigure a Twin Stread 1 sensor using the PI Configurator application.

Communication channels and update rate

Each Twin Spread sensor will communicate on two channels, one for each of the two distances the sensor measures. By default, these communication channels are set to 02 and 07.

• Channel 02 on Twin Spread 1 is used to measure the distance to Remote 1.


By default, both communication channels are set up with Fast update rate. In order to increase the lifetime between each sensor charging, you may consider changing to Normal update rate.

When you reconfigure a Twin Spread 1 sensor to act as a Twin

Spread 2, you must also choose two additional communication channels. You can choose any channels available on your system.

In this description we will use channels 09 and 11 as follows:



If you wish to reconfigure the settings, your dealer (or yourself) must use the PI Configurator application. Make sure that the channels you choose are not used by any of your other sensors!

The two twin trawls are referred to as Alpha (port) and Bravo

(starboard).

On the twin trawl Alpha, the Twin Spread 1 sensor must be mounted on the port trawl door, and the three communication transducers on the sensor must not be obstructed.

Remote 1 is placed on the centre clump of Alpha.

Remote 3 is placed on the starboard door of Alpha.

850-165186 / Rev.B


850-165186 / Rev.B

On twin trawl Bravo, the Twin Spread 2 sensor must be mounted on the port trawl door, and the three communication transducers on the sensor must not be obstructed.

Remote 2 is placed on the centre clump of Bravo.

Remote 4 is placed on the starboard door of Bravo.

This configuration will allow the Twin Spread sensors on each dual trawl Alpha and Bravo to measure the distance from the port door to the centre clump directly. It will also measure the distance between the two trawl doors.

In order to calculate the distance between the centre clump and the starboard door, you must perform the necessary settings on the PI54. This is however only possible with one of the twin trawls, as the current software version does not support this function.

Sensor setup

Observe the procedure below to set up a Twin Spread configuration with the settings defined above.

In this procedure, sensors 1, 2, 3 and 4 are used, and no other sensors are shown. Due to the fact that each Twin Spread sensor occupy two communication channels, the setup program requires that each sensor is configured as if it was two separate sensors, but not necessarily sensors 1 through 4.

How to set up marker lines

When you have chosen the Graphic display presentation, you can choose to superimpose the information from the echo sounder, and then add marker lines to see where your sensors are located in relation to the bottom and fish echoes. Note that the echo sounder data will only appear if you have mounted an echo sounder transducer to the PI54.

The following parameters will affect the way the marker lines are displayed:

• Width - you can select how thick (in pixels) each marker line shall be.

• Delay - The echo sounder information is provided by the transducer, and this transducer is located under the vessel.

The sensors are located on the gear, which may be positioned several hundred meters behind the vessel. To adjust for this delay, you can enter a value for Marker line delay. You must calculate this value (in minutes) based on the vessel’s speed, the wire length and the depth of the gear.

Alternatively, you can use the built-in Trawl caluclator to find the correct delay.

• Colour - The colour of the marker line is automatically set to the current Numeric display background colour for the same sensor. To change that colour, you must access the Display

colour setup page from the Setup menu.

• Expanded view: With the setting Sensor marker in

expansion active, the Depth and Height marker lines are shown in the expanded areas (Bottom lock, Zoom and Shift), and thus easier to read. This is a useful feature when the sensor is towed close to the bottom, and it is particulary important for the Height sensor.

• Marker white zone: When this setting is enabled, white pixels are added above and under the marker line to make it easier to distinguish it from the background colours.

• Height marker in main echogram: This setting is special for Height sensors. If you have a Height sensor on the top of a bottom trawl and the trawl opening is small, it may be difficult to tell the Height marker from the bottom echo. If this is the case, set this function to Off, and view the Height marker in expanded mode only.

81

Simrad PI54

• Height reference: The Height sensor measures the distance from the headrope to the bottom. If you use the PI54 echo sounder, set Height reference to Bottom (default), and the height marker will follow the bottom contour. If you even define the delay correctly, you will be able to see the trawl in true motion. If you do not have en active echo sounder, set

Height reference to Surface. The height will then be shown with 0 m depth as reference, and the marker line will appear as a nearly straight line some distance below 0 meters. The distance from the 0 meter line and down to the marker line will be the current height of the trawl.

Access to the marker line parameters

1 Make sure that a Graphic display presentation is active.


3 Press the GAIN+ button until the Marker line setup dialogue appears.

4 Observe the list of sensors. Only the sensors capable of providing data for marker lines are listed.

Trawl calculator

In order to calculate the correct delay, we suggest that you use the built-in Trawl calculator. Observe the following procedure:

1 Press the GAIN+ button to access the Trawl calculator setup page.

2 Set Trawl calculator mode to Auto.

3 Set Towing speed to Auto.

- In order to retrieve speed information, the relevant equipment (GPS) must be interfaced to your PI54.

- When you read the speed information from a GPS, the information is very accurate. Due to the fact that the trawl calculations are made continuously, even the slightest change in speed will be reflected on the display presentation, and you may experience that the markers fluctuate. If this is a problem, enter the average vessel speed manually.

4 If you run a pelagic trawl, set Trawl depth to Manual, and enter the mean depth.

5 If you run a bottom trawl, you can set the Trawl depth to

Bottom, and read the depth from the echo sounder.

- If a transducer is connected to the PI54, the trawl calculator will update the delay based on the data from the echo sounder.

6 Enter the Wire length. In most cases, this is the length from the stern of the vessel to the trawl doors.

7 Enter the Wire length offset. This is the distance from the trawl doors to the headrope, and normally a fixed value.

The calculator will add the wire length to the wire length offset, and use the sum of these in the calculations.

83

Simrad PI54

Depth and Height marker lines

The purpose of these marker lines is to provide an easy way to monitor the depth of the gear. The Height sensor measures the distance from the seabed and up to the sensor, while the Depth sensor measures the distance from the sea surface and down to the sensor.

1 Identify which of the sensors that are the Depth and/or

Height sensors.

2 For each sensor, set Auto to On.

- This enables the PI54 to use the delay calculated by the

Trawl calculator.

- You can also set Auto to Off. You must then calculate the delay yourself, and enter it manually in the Delay column.

3 Enter your preferred value for marker line Width.

4 Enable each individual marker line by setting Show to

On.

5 If you wish to see the marker line(s) in expanded view

(Bottom Lock, Zoom and Shift), set the Sensor marker

line in expansion to On.

6 If you wish the PI54 to draw a thin white line over and under the marker line to enhance the view, set Marker

white zone to On.

7 If you wish to view the Height marker in expanded mode only, set Height marker in main echogram to Off.

8 Select the appropriate setting for Height reference.

9 Press ENT to save the settings and exit to the graphic display presentation.

The Depth and Height marker lines are presented on the

Graphic display with continuous lines in the same background colour as in the Numeric display. To read the depth, consult the depth range on the right side of the display, or the readout in the

Numeric display.

Spread marker line

The purpose of this marker line is to provide an easy way to monitor the distance between the trawl doors.

1 Identify which of the sensors that is the Spread sensor.

2 Set the marker line to ON.

3 Enter the preferred settings for Marker line thickness and Marker line delay.

4 Press ENT to save the settings and return the the graphic presentation.

The Spread marker line is presented on the Graphic display with a continuous line. The colour of the line is the same as the background colour in the numeric presentation. To read the distance between the trawl doors, consult the depth range on the right side of the display, or the readout in the Numeric display.

If the trawl door distance is reduced or increased, this will be easily detected as the marker line moves up or down. Note that you do not monitor the depth of the trawl doors even though you use the depth scale, the scale is used as a range scale.

Surface temperature marker line

The purpose of this marker line is to provide an easy way to monitor the surface temperature. Note that this is NOT a reading from a temperature sensor, but from a feeler. Such feelers are often built into the echo sounder transducers.

1 Ensure that a proper feeler is connected to the PI54.

2 Set the marker line to On.

3 Enter the preferred settings for Marker line thickness and Marker line delay.

4 Use the ADJ button to open the Temperature setup page.

5 Press ENT to save the settings and exit to the graphic display presentation.

The Temperature marker line is presented on the Graphic display as a continuous line.

When you have chosen a graphic presentation, you can choose to superimpose the information from the echo sounder, and then add marker lines to see where your sensors are located in relation to the bottom and fish echoes. When you use a pelagic or bottom trawl, the PI54 offers certain special features to provide additional information.

86

(A) = Numeric depth display, Sensor “6D” placed on the headrope

(B) = Marker line from the footrope, added by using the Manual trawl marker setting

(C) = Marker line from the headrope using the data from Depth sensor “6D”

The recommended sensor configuration to monitor the trawl opening is to use one Height or Depth sensor on the headrope, and one Depth sensor on the footrope. However, if you only use one of these sensors, place it on the headrope. The PI54 will then manually draw the trawl opening markers for you provided that you enter the typical height of the trawl opening.

The following parameters will provide the extra information related to trawl markers:

• Headrope and footrope sensors: You need to tell the PI54 which Depth and/or Height sensor(s) you have placed on the footrope and/or headrope of the trawl.

850-165186 / Rev.B


850-165186 / Rev.B

• Trawl opening mode: This parameter decides how the trawl opening shall be recreated on the graphic presentation. If you have sufficient sensors on the trawl you must select Auto, and the the PI54 will automatically calculate the trawl opening and draw it accordingly. If you only have one sensor on the trawl opening (Depth or Height sensor on the headrope), the Manual setting will add an artificial line on the presentation. The distance from the headrope to the footrope must then be defined manually using the Manual

trawl marker parameter.

Access to the parameters

1 Make sure that a graphic presentation is active.


3 Press the GAIN+ button to access the Trawl info setup page.

Set up the parameters

1 Locate the setting Headrope sensor, and choose the sensor that you have placed on the headrope.

- If you have no Depth or Height sensors on the headrope, leave the setting to None.

2 Locate the setting Footrope sensor, and chose the sensor that you have placed on the footrope.

- If you have no Depth or Height sensors on the footrope, leave the setting to None.

3 Observe that the setting for Trawl opening mode is automatically set to Auto or Manual.

- If you have sensors placed on both the footrope and the headrope, the PI54 will be able to calculate the trawl opening automatically, and the mode is set to Auto.

- If you have only one sensor, you will need to enter a manual trawl marker.

4 If you have only one sensor, enter a value for Manual

trawl marker.

- This value must represent the actual height of your trawl opening, based on your knowledge about your gear. The information will be used by the PI54 to draw a second trawl marker line.

How to use visual aids and filters

When you use the echo sounder, several visual aids and filters are available to make the echoes easier to read and interpret.

Ping to ping filter

This function employs a filter which compares the echo information from one ping with the information from the previous ping. This will “clean up” the echogram by removing random noise spikes and interference with no correlation with the previous echo. The function will thus make the echoes appear more stable. You can switch this filter on or off.

1 Make sure that your echo sounder presentation is active.

2 Press the ADJ button to open setup dialogue.

3 Locate the Ping to ping filter parameter. Set it to ON.

Colour threshold

This function allows you to choose the number of colours to use for echogram presentation. By switching this filter on and selecting a colour in the box, all echo colours “below” the chosen colour will not be shown in the echogram. You can thus regard this as an “echo threshold” which will remove the weakest echoes.


2 Press the ADJ button to open setup page

3 Locate the Colour threshold parameter. Set it to ON.

4 Select preferred colour in the box.

Signal threshold

This is an on/off function. When activated, it will remove the weakest echoes from the screen. The threshold level is automatic. Activate with caution, as it may remove small fish or other weak unidentified echoes from the presentation.



3 Locate the Signal threshold parameter. Set it to ON.

Depth grid

When this function is enabled, thin horisontal depth lines will be added to the echogram to easier identify the depth intervals.



3 Locate the Depth grid parameter. Set it to ON.

89

Simrad PI54

Scroll speed

This function controls how fast the presentation shall scroll from right to left across the display. By defining this speed you also control the time scale. If you slow down the scroll speed, you will also increase the time between each echo sounder transmission (ping). If you choose FREEZE the presentation

(and also the echo sounder transmissions) will stop altogether.



3 Locate the Scroll speed parameter. Set it to your preferred value.

White line

When enabled, a band in the current echogram background colour is inserted immediately below the detected bottom depth.



3 Locate the White line parameter. Set it to ON.

Background colour

You can choose which background colour to use on the echogram presentation.


2 Select the Setup menu.

3 Select Palette setup.

4 Observe the first palette page appear. It contains fixed colours, which can not be altered. Press the + button repeatedly until you reach a custom page.

How to define echo sounder range

There are two parameters for range:

• Range start: This is the upper depth from which the echo sounder will provide its presentation.

• Range: This is the vertical depth range for the echo sounder.

The PI54 also offers a Phased range function, where the Range is fixed, but the Range start is modified.

The Range and Range start parameters can be manually controlled from the Echo presentation setup dialogue. In most cases, you will however only use the buttons on the keypad.

Access to the dialogue

2 On the Setup menu, select Sensor alarm/calibration.

- Observe that the Sensor alarm dialogue opens. In this dialogue, only the sensors currently activated are shown. Each of them provide various alarm functions.

3 Select minimum and/or maximum limits for the individual sensors, and activate each alarm separately.


Note that the Catch, Rip and Bottom Contact sensors can only provide alarms when they are activated, that is when their detector wires have been pulled tight.

Surface temperature alarm

The surface temperature alarm provide you with an audible and visual warning if the temperature exceeds predefined limits, or if it changes too fast.



- Observe that the Sensor alarm dialogue opens.

3 Press the GAIN+ button repeatedly until the Surface

temperature dialogue appears.

4 Select minimum and/or maximum temperature limits for the alarms, and activate each alarm separately.

5 Enter the appropriate value for the Shear alarm, and activate the alarm.


The Shear alarm will be triggered if the temperature changes faster per minute than the value you have entered.

In order to enable these alarms, your PI54 must have the relevant temperature feeler fitted!

Clearance alarms

The clearance alarm provide you with an audible and visual warning if a trawl or another towed object either moves too close to the bottom, or lifts too far off the bottom.

1 Verify that the echo sounder is operational.



- Observe that the Sensor alarm dialogue opens.

97

Simrad PI54

4 Press the GAIN+ button repeatedly until the Clearance dialogue appears.

5 Select minimum and/or maximum distance for the alarms, and activate each alarm separately.


The clearance alarm will take the current depth reading from the echo sounder and subtract the current depth reading from the

Depth sensor. The calculated depth of the trawl or towed body is then compared to the alarm limits. Due to the distance between the vessel and the trawl, you will have ample time to make the necessary adjustments to avoid damage.

If your Depth sensor is mounted to the headrope, you must create a manual depth marker. This is made in the Trawl info dialogue.

PRACTICAL USE OF THE SENSORS

The PI54 catch monitoring can operate with several different sensors. In the following, the most important information regarding installation and use of each sensor is described.

Both PI and PS sensors are described. The PI sensors have longer ranges, they can be “fast-charged” using the PI Charger, and they will provide some additional functionality. For all other practical purposes the two types may be regarded as identical. The PI54 system will automatically adapt to and work with both types, and you can also use PS and PI sensors together.

If the speed is too high, the doppler will cause the transmission frequencies to change so much that they overlap, and this will create interference. The PI54 will provide a warning if this is about to happen! You must then either change to other communication channels further apart, or reduce the maximum shooting speed.

Sensors


It may be required to change the update rate on a sensor, that is how often it sends information back to the PI54 system. A high update rate will give frequent information updates, but the sensor will use more battery power. If you need your batteries to last as long as possible, you must consider lowering the update rate.




How to change the sensor setup


The PI Configurator application is provided to enable local sensor configuration. In order to perform this configuration, you will need a personal computer (desktop or laptop) running

Microsoft® Windows® 2000 or Windows XP®, and a special cable.

Special configuration of PI Spread

The PI Spread sensor is always used with a PI Remote sensor, and these must be configured in a pair in order to make the transverse communication link work properly. In order to allow for a dual Spread application, you can use two predefined configurations: PI Spread 1 and/or PI Spread 2.

The Remote sensors are available pre-programmed for these two pairs, and the sensors are identified as Remote 1 and

Remote 2.

The two pairs must be configured as follows:

Configuration Spread sensor

PI Spread 1 PI Spread (*)

Remote sensor

Remote 1

PI Spread 2 PI Spread (*) Remote 2

(*) = The same PI Spread sensor is used for both configurations. By default, it is programmed for PI Spread 1. If you wish to use it for PI Spread 2, you must re--configure it using the PI Configurator application.

105

Simrad PI54

You can select the communication channels between the PI

Spread sensors and the vessel to suit your preferences.

Special configuration of PI Twin Spread

The PI Twin Spread sensor is always used with two PI Remote sensors, and these must be configured as a group in order to make the transverse communication links work properly. In order to allow for a dual Spread application, you can use two predefined configurations: PI Twin Spread 1 and/or PI Twin

Spread 2.

The Remote sensors are available pre-programmed for these two pairs, and the sensors are identified as Remote 1, Remote

2, Remote 3 and Remote 2. The two first (1 and 2) are the same sensors as for the standard PI Spread application.

The two groups must be configured as follows:

Configuration Spread sensor Remote sensors

PI Twin Spread 1 PI Twin Spread (*) Remote 1 Remote 3

PI Twin Spread 2 PI Twin Spread (*) Remote 2 Remote 4

(*) = The same PI Twin Spread sensor is used for both configurations.

By default, it is programmed for PI Twin Spread 1. If you wish to use it for PI Twin Spread 2, you must re--configure it using the PI Configura-

tor application.

You can select the communication channels between the PI

Twin Spread sensors and the vessel to suit your preferences.

PI Bottom Contact sensor

Purpose

The PI Bottom Contact sensor detects if a trawl is accidentally lifted off the seabed, or a purse seine is touching the bottom.

(A) = The trawl follows the bottom. The detection wire on the sensor is not released.

(B) = The trawl has lifted off the bottom, and the detection wire is released.

Main parts

(A) = Negative charging / fastening lug

(B) = Positive charging / fastening lug

(C) = Communication link (Channel 1 - 30)

(D) = Location of sensor lamp

(E) = Water switch sensor

(F) = Detection wire (in/out)

(G) = Ground weight

Daily operation

Once installed and put to use, the sensor will automatically be switched on once the waterswitch is activated. After an initial startup, the sensor starts transmission of the detector wire

(F) status (in or out). When the sensor is not in use, check that the sensor lamp (D) is not flashing from time to time, as this indicaties that the sensor is on and is discharging its batteries. In this case, wash the sensor in fresh water to remove salt and dirt.

If you operate with Fast update rate, the sensor must be charged approximately every 35 hours.

Used with Normal or Slow update rates, the operational life is approximately 60 or 250 hours respectively. The optimal sensor charging temperature is from +10 to +25° C.

Channel 6 and with Normal update rate.

The sensor and the PI54 system setup must correspond, otherwise the communication will not work.

To change the sensor setup (channel selection, update rate etc), use the PI Configurator utility.

The sensor update rate controls how often the sensor monitors whether the gear is on of off the bottom. Three settings are available. Note that a faster update rate will decrease the battery life.

• Fast (~3,2 sec): Recommended for new trawl or gear, or changes in rigging to monitor instabilities in ground gear bottom contact.

850-165186 / Rev.B

Sensors

• Normal (~5,3 sec): Recommended for normal fishing.

• Slow (~33 sec): Recommended if maximum operational battery life before charging is required. The system will be more sensitive to bad communication conditions due to the slow data update.

System configuration

Sensor configuration: The sensor must be configured with a unique sensor number. Select update rate and channel number according to the sensor’s configuration. Write down this configuration for future reference.

Status & Receiver: The Interference filter must be switched on.

Set it to level 9 if you have noise problems from other hydroacoustic sources. Note that with the filter on, it will influence the signal spectrum shown in the Status display.

Catch/Bottom sensor filter: Switch this filter off. Set it to

Light or Heavy only if you experience excessive noise.

Mounting

Location: Place the sensor where you wish to monitor bottom contact. This is normally in the center of the net.

Seize the attachment ring (A) for the stay underneath the net, then put two carabine hooks inside the footrope forming a bridle of 15 to 20 cm securely holding the sensor in a stable position.

Penetration ring: Place the penetration ring (B) for the detection wire approximately 30 cm rear of the footrope. Before final seizing, mount the sensor to the carabine hooks and check that the detection wire (E) passes trough the center of the penetration ring (B). Remove any net on the inside of the penetration ring.

109

Simrad PI54

Note:

110

Set up: Correct function requires that the length of the stay (F) and the detection chain (G) are trimmed with regard to each other and the gear in use. Standard delivery includes a 63 cm stay and 39 cm detection chain for use with 14 to 16 inch bobbins or rock hoppers (C).

Penetration ring: Place the penetration ring (B) for the detection wire approximately 30 cm rear of the footrope. Before final seizing, mount the sensor to the carabine hooks and check that the detection wire (E) passes trough the center of the penetration ring (B). Remove any net on the inside of the penetration ring.

Simrad PI54

Note:

Set up: Correct function requires that the length of the stay (F) and the detection chain (G) are trimmed with regard to each other and the gear in use. Standard delivery includes a 63 cm stay and 39 cm detection chain for use with 14 to 16 inch bobbins or rock hoppers (C).

Adjustment: Lay the sensor on an elevated surface. Adjust the length of the detection chain (G) as necessary. Observe detection wire (E) movement while simulating bottom contact by raising the weight. Tilt the weight approximately 25° to compensate for drag forces when towed through the water, and adjust the stay length to be taut. To avoid damage, remove the weight before coiling the gear on the drum.

The sensor’s detection wire must always be allowed to pass freely through the center of the penetration ring when it is deployed. Attach the rubber straps so that the sensor is held horizontally during towing.

PI Catch sensor

Purpose

The PI Catch sensor detects when the trawl has been filled with fish. The sensor monitors the opening of the meshes in the cod end, and will be activated once the volume caught is enough to pull the detector wires.

850-165186 / Rev.B

Catch sensor principle: Three sensors are mounted at the cod end of the trawl to detect the amount of fish caught.

Main parts



(C) = Communication link



(F) = Detection wires

Daily operation

To monitor the filling rate, we recommend that you use minimum two sensors. The first sensor is located at the far end of the cod-end indicating that the trawl is fishing, while the second sensor tells when to haul. Due to the fish moving back and forth in the cod-end, the sensor will normally change status (on/off) several times until the volume caught keeps the opening of the meshes stable.

115

Simrad PI54

Note:

116

Once installed and put to use, the sensor will automatically be switched on once the waterswitch is activated. After an initial startup, the sensor starts transmission of the detection wires (F) status (in or out). When the sensor is not in use, check that the sensor lamp (D) is not flashing from time to time, as this indicaties that the sensor is on and is discharging its batteries.

In this case, wash the sensor in fresh water to remove salt and dirt.

If you operate with Fast update rate, the sensor must be charged approximately every 35 hours. Used with Normal or Slow update rates, the operational life is approximately 150 or 300 hours respectively. The optimal sensor charging temperature is from +10 to +25° C.


Presentation

On the PI54 display, the Catch sensor status is displayed with graphic symbols. The timers count the total number of minutes the sensor has been activated (red rectangle). If only predicted timer values exist, the timer characters are shown in grey. If the sensor communication is lost, the graphic symbol is replaced by the characters ***.* (in grey).

Sensors


On delivery, all Catch sensors are configured in Channel 4 and with Normal update rate. If you use more than one Catch sensor, make sure that you set them up to operate on different channels and with different sensor numbers!



The Catch sensor can be configured (using the PI Configurator software) to act as a FA701 catch sensor. This will allow the sensor to be used with the Simrad FS trawl sonar. The communication channel on the FS sonar must be set up to correspond to the equivalent sensor number (1, 2 3 or 4).

The sensor update rate controls how often the amount of fish caught is measured and transmitted to the vessel. Three settings are available. Note that a faster update rate will decrease the battery life.

• Fast (~5,3 sec): Recommended for trawling in areas where the rate of filling is very high. Use this setting to avoid damage to the trawl or excessive catches.

• Normal (~33 sec): Recommended for normal fishing.


When the Catch sensor is configured as an FA701, it will have a constant update rate of approximately 80 seconds. This rate must not be changed.

Mounting

Location: Attach the sensor on top of the cod-end where the catch is to be monitored. As the cod-end fills, the net’s meshes will open pulling the detector wires and thus activating the sensor.

Sensor attachment to a net with an approximate mesh size of 140 mm. The distance between the anchor points for the attachment rings and rubber straps will vary according to mesh size and sensitivity required.

Attachment: The Catch sensor’s orientation towards the vessel is maintained by the steel and nylon attachment rings. The number of meshes the attachment rings are supported between must be restricted to avoid unnecessary stress on the sensors fastening lugs when the cod-end is filled to maximum. The use of both nylon and steel attachment rings is required to secure the sensor lugs if excessive forces are applied on them. The nylon rings will stretch or break down, but the steel ring will prevent the sensor from being lost. Note that two steel rings must be mounted on the same side.

Purse seine: In order to secure stable communication with the vessel’s hydrophone, it is very important that the sensor is allowed to hang freely with the top end pointing towards the surface during shooting and pursing.

Attach the sensor to a standard purse ring with two separate wires (A).

Mount one end of each wire to a common snap hook (B), and place another snap hook at the other end of each wire to snap onto the sensor.

Mount a safety line (C) between the sensor and the adjacent bridle/purse ring. Make sure that security line does not prevent the sensor from hanging freely!

Remove the sensor from the purse seine before it passes through the power block.

• Slow (~34 sec): Recommended to monitoring a stable situation over time, focus on door not falling over, broken sweep lines etc. during the tow. The system will be more sensitive to bad communication conditions due to slow data update. This mode provides longest operational battery life before charging.






Mounting

The Spread and Remote sensors must be mounted in special adapters on each trawl door. These adapters must be installed aforehand. Detailed information on how to install the adapters are provided with the installation kit.

Installation principle

The PI Spread sensor is mounted on the port door, while the PI

Remote sensor is mounted on the starboard door. It is essential that there is a clear line of sight between the two transverse communication “eyes” (one on each sensor), and between the top of the PI Spread sensor and the hydrophone on the vessel.

Daily operation

Once installed and put to use, the Twin Spread sensor will automatically be switched on once the waterswitch is activated.

After an initial startup, the sensor starts interrogating the

Remote sensors to measure the two distances. The results are transmitted to the vessel. When the sensors are not in use, check that the sensor lamps (D) do not flash from time to time, as this indicates that the sensor is on and is discharging its batteries. In this case, wash the sensor in fresh water to remove salt and dirt.


Slow update rates, the operational life is approximately 48 or 70 hours respectively. For the Remote sensors, the batteries will last approximately 50, 100 and 150 hours respectively. The optimal sensor charging temperature is from +10 to +25° C.

The two rubber inserts provided at the bottom of each sensor adapter must not be replaced with any other types or designs. It is essential that these inserts provide a secure cradle for the sensors, but they must also allow for free water circulation to allow the sensor’s water switch to engage. Also, the design of the inserts allows sand and mud to flow out when the trawl doors are pulled up from the water.

On the PI54 display, the distances between the trawl doors are displayed in the numeric display. Two rectangles are used, one for each distance. If the distance is increasing or decreasing, this is shown with two arrows and the variation in meters per second.

When the readings are stable, the digits are shown in black colour. When the values are predicted, the digits are grey, and if the contact is lost, the characters **.* are shown in grey. The characters ±±.± indicate that the Twin Spread sensor has lost contact with the Remote sensor(s), while characters ??.? means that the Remote sensors are out of range.

Sensors


You can operate two sets of Twin Spread sensors, these sets are identified as Twin Spread 1 and Twin Spread 2.

Twin Spread 1 uses two Remote sensors: Remote 1 and 2.

Twin Spread 2 uses two Remote sensors: Remote 2 and 4.

On delivery, all Twin Spread sensors are configured as Twin

Spread 1 in Channels 2 and 5, with Fast update rate, and for use with Remote sensors 1 and 3. The four Remote sensors can be ordered pre-programmed from Simrad, but if you wish to use a

Twin Spread 2 set-up you must re-configure a Twin Spread 1 sensor using the PI Configurator utility.

The Twin Spread sensor and the PI54 system setup must also correspond, otherwise the communication will not work.

The sensor update rate controls how often the sensor reads and reports the door spread. Three settings are available. Note that a faster update rate will decrease the battery life.

• Fast (~5,5 sec): Recommended for new trawl or gear or changes in rigging to monitor any instabilities or unexpected changes. This mode provides the shortest battery life before charging.

SENSOR CHARGERS

Note:

Overview

Two different battery chargers can be used to charge the PI and

PS sensors:

• PI Charger

• PS30 Charger

Even though both chargers can be used to charge any of the sensors (except the PI Height sensor), only the PI Charger will provide fast and intelligent charging of the PI sensors.

The PI Height sensor can only be charged with the PI Charger.

Topics

→ PS30 Charger, page 167

164

850-165186 / Rev.B

850-165186 / Rev.B

Sensor chargers

PI Charger

Purpose

The PI Charger is an intelligent battery charger for fast and secure charging of the PI sensors. The charger will automatically set up the correct charging current depending on the sensor type and the battery temperature. Even though the PI

Charger is designed for fast charge of the PI sensors, it can also charge the PS sensors, but only at normal charge rate. A fuel meter shows the status of the battery during the charge.

Daily operation

1) Attach the charging clamps to the sensor as follows:

Red clamp: Positive fastening lug (+)

Black clamp: Negative fastening lug (-)

2) Ensure that attachment materials, rope etc. do not short circuit the charging lugs, preventing charging and causing damage to the sensor lugs.

Once connected, the charger will identify whether the sensor connected can be fast charged or not.

The battery temperature will always be monitored for a fast charging sensor. A sensor which can not be fast charged, will not display the battery temperature, and the temperature LED will be dark.

3) Observe the charge times and temperature limitations:

Fast charge: First approximately 1 hour for 70% battery capacity, then approximately 3 hours to reach 100% capacity.

Once fully charged, a constant trickle charge will compensate for self discharging. Note that fast charging applies to PI sensors only!

Normal charge: 16 hours for full battery capacity. This mode applies for charging outside specified temeparture range, and for all PS sensors.

Charging temperature: For best results, keep the ambient temperature between +10 and +25°C. Do not charge in temperatures above +50°C or below 0°C!

165

166

Indicators

(A) = Mains: 12 to 32 Vdc

(B) = Fuel meter. The number of LEDs illuminated shows the current charging status. A complete charging cycle is indicated with all “full” battery. Charging:

Fast: Fast flash

Normal: Slow flash

Trickle: On, off every 4 second

(C) = Battery temperature indicators during fast charging:

Green: Battery temperature between +5 and +40°C. Fast charge is enabled.

Green and Blue: Battery temperature between 0 and +5°C.

Fast charge is disabled, normal charge is used.

Green and Red: Battery temperature between +40 and

+50°C. Fast charg disabled, normal charge is used.

Blue: Battery temperature is below 0°C. No charging takes place.

Red: Battery temperature is above +50°C. No charging takes place.

Charging a sensor at sub-zero temperature might develop explosive gases representing a potential danger. Simrad assumes no liability for improper charging, or the use of other chargers than those approved by Simrad.

Automatic configuration

The charger communicates with the sensor at regular intervals.

The fast charge cycle is controlled by data exchanged between the PI sensor and the charger, and a series of safety mechanisms controls the termination of the fast charging current.

The PS sensors do not communicate with the charger. A constant charge current of 58 mA is then set up by the charger regardless of the battery temperature.

3) Observe the sensor’s indiactor lamp. It will flash once every four seconds during charging.

4) Observe the charge times and temperature limitations:

Normal charge: ~16 hours for full battery capacity.

Charging temperature: To obtain best results, try to keep the ambient temperature between +10°C and +25°C. The sensor must not be charged in temperatures above +50°C or below 0°C!

General guidelines

Operational time and service life of the sensor’s NiCd battery depends on proper use and regular charging. Observe the following precautions, as these will have an influence on the battery performance:

• Observe the charging temperatures.

• Charge sensors regularly. Avoid draining the sensor battery completely before charging.

• Charge the sensor battery before storage, and at three-month intervals under long-term storage.

• Operational life may be initially reduced after long-term storage or charging for a long time.

• Sensors are not damaged by being left attached to a charger for several days. However, do not store the sensor for extended periods under charge.

• We recommend that a wooden box is made to keep the sensor in a secure place during charging and storage. Make openings in the bottom to drain for sea water.

Battery depleted frequently

If the charger lamp is illuminated, but the sensor lamp does not flash every four seconds, the battery is not being charged properly. Most likely, this is because the sensor was not switched off when the charger was connected.

To correct, charge the sensor for ten minutes, then disconnect the alligator clips. Use a small wire, and make contact between the water switch sensor and one of the fastening lugs. This will cause the sensor to flash its start-up code. If not, wash the sensor in fresh water to disengage the water switch.

Depth calibration

This function is used to enable calibration of the PI54 Depth sensor.

To access this function, press the MENU button to open the main menu. Then, open the Setup menu, and select Sensor

alarm/calibration.

When the dialogue opens, press the GAIN+ button a few times to open the Depth calibration dialogue.

The Depth calibration feature will calibrate the current depth of the Depth sensor to one -1- meter.

1 Lower the sensor over the side to a depth of one meter, to a certain draft depth plus one meter, or to any reference level that you wish to be defined as one meter.

2 Once the reading from the sensor is stable, set Depth

sensor calibration to YES.

The calibration takes one minute. While the process is running, the numerical presentation is shown with grey text. Note that the sensor must be submerged into salt water to perform the calibration.

Echo presentation setup

These settings are used to set up the echo sounder presentation parameters on the PI54. The operational parameters are set up using the Echo sounder setup dialogue.

To access the parameters, press the ADJ (Adjust) button when you have an echo sounder presentation in the active window.

You can also press the ENT button, and then select Echo

presentation setup on the Echo quick menu.

850-165186 / Rev.B

Range start: This is the upper depth from which you wish the echo sounder shall start. This value will typically be 0 meters, but you may for example set up the echo sounder to only present echoes from 5 meters below the sea surface and downwards.

Range: This is the vertical depth range for the echo sounder.

You can set it to change depth range automaticially (AUTO), or you can define your own fixed range. The maximum range will depend on the chosen echo sounder frequency, as the 38 or 50 kHz modes will detect echoes deeper than the 200 kHz mode.

Gain: This is the gain in the echo sounder’s preamplifier. The gain must be defined manually, and you can choose any value between 1 and 100%. In most cases, use a value around 60%. If you use too much gain, the echogram will contain a lot of noise and false echoes.

White line: This parameter allows you to switch the White line function on or off. When enabled, a band in the current echogram background colour is inserted immediately below the detected bottom depth.

177

Simrad PI54

178

Expansion window: The PI54 provides bottom expansion and zoom functions. When one of these is enabled, you can control the depth range in the expanded window using this parameter.

To enable the bottom expansion function, press the B-LCK button on the keypad. To enable the zoom function, press the

ZOOM button. To disable both, press the STND or SHIFT buttons. You can also access this parameter in the Graphic

setup.

TVG (Time Varying Gain): The PI54 provides a TVG function to enhance the echoes from deeper waters. You can switch the

TVG to OFF (not recommened), or select either Special (40 log

R) or Normal (20 log R) setting, depending on your preferences.

For all normal operation, leave it at Normal. Try Special if you are looking for echoes close to the seabed in deeper waters.

Ping to ping filter: This function employs a filter which compares the echo information from one ping with the information from the previous ping. This will “clean up” the echogram by removing random noise spikes and interference with no correlation with the previous echo. The function will thus make the echoes appear more stable. You can switch this filter on or off.

Signal threshold: This is an on/off function. When activated, it will remove the weakest echoes from the screen. The threshold level is automatic. Activate with caution, as it may remove small fish or other weak unidentified echoes from the presentation.

Colour threshold: This function allows you to choose the number of colours to use for echogram presentation. By switching this filter on and selecting a colour in the box, all echo colours “below” the chosen colour will not be shown in the echogram. You can thus regard this as an “echo threshold” which will remove the weakest echoes.

Depth grid: When this function is enabled, thin horisontal depth lines will be added to the echogram to easier identify the depth intervals. When you operate with a graphic display, this function can also be switched on and off in the Graphic setup.

Transmit pulse length: This parameter allows you to choose the length of the echo sounder pulse transmissions. You can choose OFF (to observe the ambient sea noise), SHORT,

MEDIUM, LONG or AUTO. In most cases, select AUTO. The

PI54 will then automatically choose the pulse length depending on your current depth range. If you choose to try a manual mode, try long pulse lengths when you operate in deeper waters, and shorter pulses with higher frequency in shallower waters.

850-165186 / Rev.B

Note:

References

As a general rule, short pulses serve to make the echoes from various objects more distinct. It is therefore used to obtain optimal vertical resolution, as it will separate individual fishes from each other and from the bottom. Longer pulses will penetrate deeper, but with less resolution.

Transmit power: This parameter allows you to change the power output from the echo sounder. You can choose OFF (and no echogram will appear!), 10 W, 100 W, 500 W, 1000 W or

AUTO. In most cases, select AUTO. The echo sounder will then automatically adjust the power output depending on the current operational frequency and the current depth.

Scroll speed: This function controls how fast the presentation shall scroll from right to left across the display. By defining this speed you also control the time scale. If you slow down the scroll speed, you will also increase the time between each echo sounder transmission (ping). If you choose FREEZE the presentation (and also the echo sounder transmissions) will stop altogether. Note that this parameter can also be set in the

Graphic setup.

The echo sounder frequency you choose must be supported by the transducer you have installed!

PI54. This operation is only carried out once, and that is during the system installation. DO NOT ADJUST these settings during normal operation of the echo sounder, as incorrect settings may result in damage to the PI54 and/or the transducer(s).

For more detailed information on transducer installation, consult the PI54 installation manual.

Select transducer: Enter the type and main parameters of each transducer connected to the PI54 system.

Transducer type: Enter transducer type. You can leaf through a number of predefined transducer types, or define your own.

Note that some of the predefined types are “dual” transducers, which means that both transceiver outputs ports (Echo1 and

Echo2) will be used.

Transducer port: Enter which transceiver port (output) the transducer is connected to; Echo1 or Echo2. With the predefined transducer types, the ports are also set by the software.

Transducer beam angle: Enter the fore-and-aft and athwartships beam angles for the transducer. With the predefined transducer types, this information is already known.

Transducer depth: Enter the vertical distance between the transducer face and the water surface. Normally, this value can be fixed, but if it changes considerably when the vessel is loaded, you may need to change it. The value is used to provide you with a correct depth under keel (DK) value in the echo sounder presentation.

Echo sounder parameters

Keel depth below surface: Enter the distance between the keel and the water surface. Normally, this value can be fixed, but if it changes considerably when the vessel is loaded, you may need to change it. This parameter is used to provide you with the correct depth below keel value in the echo sounder presentation.

Data on NMEA-out from: Choose if the echo sounder data output on the NMEA interface shall be taken from the 38 kHz,

50 kHz or 200 kHz echo sounder frequency.

Alarm for fish, strength: This parameter enables the fish detection alarm, and adjusts the sensitivity (strength). With high sensitivity, smaller fish (with weaker echoes) will trigger the alarm.

Depth DS fish: This parameter allows you to define a vertical depth area (between a maximum and a minimum depth) in which the fish alarm can be triggered. Echoes outside the chosen area will not trigger the alarm.

Depth DK alarm (minimum and maximum values): This parameter enables an alarm to sound off if the water depth under the keel is shallower or deeper than two predefined limits.

Water profile: This parameter sets up the echo sounder for operation in fresh or salt water.

Velocity of sound in water: This parameter allows you to fine tune the performance of the PI54 echo sounder to the speed of sound in the water. However, in most cases, the accurate speed is not known, and this parameter is not important at all when operating in shallow waters. For all practical purposes, leave this setting to the default value of 1470 m/s.

Time scale: This parameter allows you to switch the time scale in the echo sounder presentation on or off.

181

Simrad PI54

Restart of AUTO pulse/power: If you have set the transmit power and pulse length parameters to Auto, the echo sounder will automatically restart the parameters at fixed intervals to ensure correct settings. By means of this parameter, you can control the intervals. In most cases, leave this setting to 20 seconds, which is the default value.

Echo sampling: Using this function, you can select if the automatic ping rate shall be defined by the current depth or the current range.

Demo mode: This parameter allows you to run the echo sounder in a “demonstration” mode. When this mode is enabled, the echo sounder will automatically use a “demo transducer” to avoid damage to the output circuitry.

Graphic setup

These settings are used to set up the PI54 parameters related to the Graphic display.

184

The Graphic display shows the data from the sensors in their alphanumerical presentations, as well as historical plots sumperimposed on the echogram. The digits in the alphanumerical presentations are black when the data are valid, they are grey when the values are only predicted, or they are replaced with asterix characters (*) when the contact with the sensor is lost. The yellow pulse lamp is lit every time information in received back from the sensor. The positioning of the alphanumerical presentations is controlled by the order of which the sensors were configured in the Sensor setup dialogue.

To access the parameters, press the ADJ button when you have a graphic display in the active window. You can also press the

MENU button to access the Echo quick menu, and then select

Graphic setup.

Superimpose echo sounder: When activated, the presentation from the echo sounder is added to the graphic display. Note that this option is only valid if you have the echo sounder transducer(s) installed, and the echo sounder is set up for normal operation. You can only switch this function on or off.

Scroll speed: This function controls how fast the presentation shall scroll from right to left across the display. By defining this speed you also control the time scale. If you slow down the scroll speed, you will also increase the time between each echo sounder transmission (ping). If you choose FREEZE the presentation (and also the echo sounder transmissions) will stop altogether. Note that this parameter can also be set in the Echo

presentation setup.

Additional information: The feature will display an information bar below the numeric presentations on the Graphic display. The bar provides key technical pararameters related to the echo sounder operation; frequency, output power and pulse length. It will also show you the ambient air temperature, the vessel’s speed and the current depth. If you use the selector pad to adjust the depth of the VRM (Variable range marker) or the echo sounder receiver gain, it will show you the current depth and gain settings while you do this. The default setting is ON.

Depth grid: When this function is enabled, thin horisontal depth lines will be added to the presentation to easier identify the depth intervals. Note that this function can also be switched on and off in the Echo presentation setup.

Data window sensors: When you have set up the Graphic display on only a half screen, there is not space for more than three sensor presentation rectangles at the top of the display.

With this parameter, you can choose if you wish to see sensors

1, 2 and 3 or 4, 5 and 6. When you have set up the Graphic display on a full screen, this parameter is not visible.

Echo strength colour scale: This parameter allows you to switch the echo strength colour scale on the left side of the

Graphic display presentation on or off. A turquoise colour indicates the weakest echoes, while dark red indicates the strongest echoes. Note that this colour scale can not be enabled simultanously with the temperature scale.

Time scale: This parameter allows you to switch the time scale in the Graphic display presentation on or off. When enabled, it is positioned immediately above the echogram. Note that the time scale relies on the chosen scroll speed: a low speed results in a long time scale and vice versa.

Expansion window: The PI54 provides bottom expansion and zoom functions. When one of these is enabled, you can control the depth range in the expanded window using this parameter.

To enable the bottom expansion function, press the B-LCK button on the keypad. To enable the zoom function, press the

ZOOM button. To disable both, press the STND or SHIFT buttons. You can also access this parameter in the Echo

Interface setup

These settings are used to set up the PI54 parameters related to the communication to and from peripheral units. To access the parameters, press the MENU button to access the main menu.

Then, select Interface setup on the Setup menu.

The parameters in the Interface setup will normally only be accessed during system installation. If you change any of these parameters during normal operation, your system may not be able to communicate with external devices, and this may lead to operational degradation.

Background

By means of the connectors on the rear side of the PI54 cabinet, it can communicate with several peripheral devices. This is useful, as it allows you to export and import information to and from these devices. In order to establish this communication, the devices on each end of the cable must speak the same

“language”. The National Marine Electronics Association

(NMEA) has defined communication standards for maritime electronic equipment, and the PI54 system conforms to these standards. The most common standard is NMEA 0183, and the

National Marine Electronics Association describes it as follows:

“The NMEA 0183 Interface Standard defines electrical signal requirements, data transmission protocol and time, and specific sentence formats for a 4800-baud serial data bus. Each bus may

have only one talker but many listeners.” For more information about the National Marine Electronics Association and the

NMEA 0183 standard, refer to the organization’s web pages at www.nmea.org.

Telegrams

To move information between two electronic units, the data are collected in telegrams. The content (protocol) of each telegram is defined by the NMEA standard, and several telegram types exist to allow different type of data to be distributed. Unless you wish to write your own software, you do not need to know how these telegrams are designed. However, whenever you set up equipment interfaces, you need to ensure that each system on your communication line is set up to send and receive the same telegram. The standard allows one system to send data (a

“talker”) and several others to receive data simultanously

(”listeners”) on the same line. Therefore, you must ensure that all products receiving data on a communication line is set up to receive the same telegram(s) that the transmitting product provides.

Marker line setup

These settings are used to set up the PI54 parameters related to the marker lines on the graphic display. When enabled, these marker lines will be superimposed on the graphic display.

To access the parameters, press the ADJ button when you have a graphic display in the active window. Then, press the GAIN+ button two times until the settings appear. You can also press the

MENU button to access the Echo quick menu, select Graphic

setup (8), and then press the GAIN+ button until the setup dialogue appears.

Note:

850-165186 / Rev.B

The Marker line setup controls how the markers from the applicable sensors are displayed on the Graphic display. The setup function will read the current sensor configuration, and list the relevant sensors on the menu.

In the example provided, the PI54 is set up with two Depth sensors, one Height sensor, as well as input from a surface temperature feeler. These will all provide information to the graphic display. Those sensors that will not provide presentable information will not be listed.

The Catch and Bottom Contact sensors will not be able to provide information for such markers, as they only trigger on/off.

Auto: This option allows you to enable and use the delay automatically calculated by the Trawl calculator. Select On to enable the function. The current delay is then shown with grey characters, and the values can not be edited. If you select Off you must enter the Delay values manually. Note that the Trawl

calculator must be enabled to provide the delay information. If such information is unavailable, the On/Off choice is shown with grey characters.

197

Simrad PI54

Delay: For each sensor marker, you can define a presentation delay. The echogram information provided by the PI54 is from directly below the hull, but the marker information come from the sensors, which are positioned some distance away. You can therefore calculate a delay (in minutes and seconds) manually based on the wire length, towing depth and speed, and with this delay place the marker at its correct location on the echogram.

You can also enable the Trawl calculator function, and have the delay calculated automatically.

Width: For each sensor marker, you can define the width of the marker line in pixels. The colour of the line will automatically be set to the current background colour of the numeric presentation of the sensor data. The default line width is 2 pixels.

Show: Switch the marker(s) on or off to suit your preferences and need for information. Use the palette to define unique colours in order to distingush the markers from each other.

Surface temperature: This parameter allows you to superimpose a temperature curve on the graphic display. To read the values, you need to enable the temperature scale in the

Graphic setup. You can change the width of the temperature marker line, and choose a colour from the palette.

Sensor marker in expansion: With this setting active, the

Depth and Height marker lines are expanded, and thus easier to read. This is a useful feature when the sensor is towed close to the bottom, and it is particulary important for the Height sensor.

Marker white zone: When enabled, white pixels are added above and under the marker to make it easier to distinguish it from the background colours.

Height marker in main echogram: If you have a Height sensor on the top of a bottom trawl and the trawl opening is small, it may be difficult to tell the Height marker from the bottom echo. If this is the case, set this function to Off, and view the Height marker in expanded mode only.

198

850-165186 / Rev.B

References

Height reference: The Height sensor measures the distance from the headrope to the bottom. If you use the PI54 echo sounder, set Height reference to Bottom (default), and the height marker will follow the bottom contour. If you even define the delay correctly, you will be able to see the trawl in true motion. If you do not have en active echo sounder, set

Height reference to Surface. The height will then be shown with 0 m depth as reference, and the marker line will appear as a nearly straight line some distance below 0 meters. The distance from the 0 meter line and down to the marker line will be the current opening of the trawl.

The Receiver setup parameters have a major influence on the

PI54 performance. The default settings are those we have found to be the best for general use, but for individual installations optimized settings may enhance the performance.

Interference filter: When this filter is active it will remove interference (noise and false echoes) from other echo sounders and sonars in the the vincinity of your own vessel. It may not remove all interference, but in most cases you will find this filter to be very efficient. If you suffer from poor range performance, and the spectrum on the Status Display is nearly flat, this filter may also prove useful. A normal sensor will then show up with a narrow peak at its dedicated frequency. This filter is by default switched on and set to level 9, and will tend to prioritize stronger signals.

Interference filter level: Use this setting to control the strength of the Interference filter. 9 is the default value and the heaviest filtering. Selecting 0 will hardly have any effect, and is really equivalent with the filter switched off.

Sensor filter: The PI54 is designed to quickly update data.

After the sensors have been submerged, the receiver requires only three consecutive pings from individual sensors to calculate and display their respective information. However, if you experience problems with the reception, you may also try this filter: it will average the data received from the sensors. Light filtering will average the data received by the last four pings, while heavy filtering averages the data received by the last eight pings. We recommend that you only use heavy filtering if there are large fluctuations in the displayed data, or if the rate of change is small. Reduced filtering shortens the delay between updating the changes in sensor location and the corresponding displayed information. Default setting is LIGHT.

Catch/Bottom Sensor filter: This filter is used to smooth out the information from the Catch and Bottom Contact sensors.

When the filter is switched off any change in sensor status will immediately be shown on the display. Set to LIGHT the change in status must last and remain stable for at least two pings before the display is changed. When HEAVY filtering is applied the change in status must last and remain stable for at least four pings before the change is shown on the PI54 display.

AGC (Automatic Gain Control): This function allows the PI54 to automatically control the receiver gain. The units reads and interprets the received signal strength, and adjusts the gain accordingly. During normal operation, ON is the recommended

(and default) setting.

Manual gain: If you decide to switch the AGC off you must set the gain manually. This can be useful when you work at maximum detection ranges with favourable noise levels. The default setting is 0 dB, and you can adjust the gain in steps of

20 dB.

Multipath filter (MP filter): When you operate in an areas with substantial reverberation due to bottom topography, or in shallow waters, you may experience problems when consecutive operating channels have been configured, but the corresponding sensors are not in use. False signals and sporadic error values can also be caused by other types of hydroacoustical equipment operating on the PI54 frequency range. This filter has been implemented to remedy for such interference problem. Default setting is OFF.

Multipath filter level (MP filter level): When the Multipath

filter has been enabled, you can adjust the filter level in small steps to correct the interference problem. Lower filter values represent stronger filtering. It is best to experiment with this parameter by reducing the value in steps of 3 dB until the

209

Simrad PI54

Note: detection error disappears. Check that the signals from the sensor in use are still being received, if they are not, the filter will not be of help in this particular situation. The filter’s effectiveness is both location and net specific. Therefore, the same parameters will not necessary work in different areas or using various types of nets. Default setting is 42 dB.

Detection Threshold (DT): This function will inhibit reception of the weakest signals. If you experience problems with interference signals generating false data and all of the configured sensors are operative (analogous with the Multipath problem); increase the Detection Threhold value carefully in steps of 1 dB. High values allow only strong sensor signals to be detected. A lower threshold value will provide greater range if conditions are optimal, but if too low, interference will be detected. It is best to experiment with different values to determine which to employ.

If the Detection Threshold (DT) value is set higher than 28 dB, all signals will be prevented from being detected.

Max shooting speed: The PI54 has a built in doppler compensation function which is configured using this parameter.

The parameter and related function is however only relevant if sensor data is desired while the purse seine is being deployed. It has no effect once the vessel is stopped waiting for the net to sink. Note that if you set this parameter too high, you can create a conflict with the channel selection. Should this situation arise, the following message will appear: Max shooting speed differs

from wanted, channels are set too close to each other.

Sensor alarms

These settings are used to set up the PI54 parameters related to sensor alarms.

To access the parameters, press the MENU button to open the main menu. Then, open the Setup menu, and select Sensor

alarm/calibration.

Each sensor has an individual alarm setting, and you can also trigger alarms to warn you about sudden temperature changes and shallow water. Whenever an alarm is triggered an audible signal is provided, and a message on the display presents the cause of the alarm. Unless the reason for the alarm is corrected, or the alarm disabled, it will sound again after 20 seconds.

Due to the amount of choices available for the PI54, the alarm parameters are organized in three dialogues.

• Sensor alarm: This dialogue allows you to defined alarms related to the information provided by the sensors.

• Surface temperature: This dialogue allows you to set up alarms to warn you about surface temperatures, and to indicate sudden temperature changes.

• Clearance: This dialogue allows you to define alarms to monitor if a trawl or towed object comes too close or too far off the bottom.

The Sensor alarm/calibration choice on the Setup menu also allows you to define parameters for depth calibration and offset.

These are explained separately.

These settings are used to set up the PI54 parameters related to the Trawl calculator.

To access the parameters, press the ADJ button when you have a graphic display in the active window. Then, press the GAIN+ button four times until the settings appear. You can also press the MENU button to access the Echo quick menu, select

Graphic setup (8), and then press the GAIN+ button four times.

850-165186 / Rev.B

Purpose

The Trawl calculator is used when you have chosen to superimpose sensor data onto the Graphic display. However, in order to position the sensor marker correctly on the echogram, you need to calculate the delay. This is because the echo sounder information is provided by a transducer located under the vessel, while the sensors are located on the gear, which may be positioned several hundred meters behind the vessel. To adjust for this delay, you must calculate the value (in minutes) based on the vessel’s speed, the wire length and the depth of the gear.

You can do it manually and enter a Marker line delay in the

Marker line setup dialogue, or you can leave the calculation to the Trawl calculator.

For a complete procedure, refer to the Operational procedures chapter.

Parameters

Trawl calculator mode: Select Auto or Manual. When

Selecting Auto allows you to retrieve or enter trawl data, and the PI54 will perform the calculation. Selecting Manual switches the Trawl calculator off.

Towing speed: Select Manual to enter the average vessel speed, or Auto to allow the PI54 to retrieve the information automatically. If you select Auto you can choose to read the speed over ground (SPG) or the speed through water (STW).

221

Simrad PI54

Note:

In order to retrieve speed information, the relevant equipment

(GPS) must be interfaced to your PI54.

When you read the speed information from a GPS, the information is very accurate. Due to the fact that the trawl calculations are made continuously, even the slightest change in speed will be reflected on the display presentation, and you may experience that the markers fluctuate. If this is a problem, enter the average vessel speed manually.

Trawl depth: Select Manual to enter average trawl depth. If you run a pelagic trawl, you must use this setting. Select

Bottom if you run a bottom trawl, and you expect the trawl depth to be equal to the depth measured by the echo sounder.

Note that in order to update the calculator automatically, the echo sounder must be operational providing valid depth data.

These are shown with grey characters.

Wire length: Enter the length of the trawl wire. In most cases, this is the length from the stern of the vessel to the trawl doors.

Wire length offset: Enter the distance from the trawl doors to the headrope. This is normally a fixed value. The calculator will add the wire length to the wire length offset, and use the sum of these in the calculations.

Calculated marker delay: When in Auto mode, the delay is shown in minutes and seconds.

4, 5 and 6), this will limit the vessel’s speed. The reason for this is the doppler effect. If the speed is too high, the doppler will cause the transmission frequencies to change so much that they overlap, and this will create interference. The PI

Configurator will provide a warning if this is about to happen! You must then either change to other communication channels further apart, or reduce the maximum shooting speed.

Simrad PI54


It may be required to change the update rate on a sensor, that is how often it sends information back to the PI Configurator system. A high update rate will give frequent information updates, but the sensor will use more battery power. If you need your batteries to last as long as possible, you must consider lowering the update rate.

Communication Channel

This parameter allows you to redefine the sensor’s transmission channel (1 to 30).

Sensors send information using specific frequencies, each designated as an individual channel. PI and PS sensors have 30 channels to choose from, and the FA701 sensors have four. The frequency range of these channels are of from 43.5 to 49.5 kHz for PI and PS systems, and 70 to 80 kHz for FA710 systems.

This is a key parameter. Unless the communication channel defined in the sensor matches the channel defined on the host PI system, the communication will not work!

Operation

To operate, click the up or down arrow on the Communication

Channel spin box until the desired channel is shown in the text box. It is also possible to enter a channel directly by clicking the text box and inputting the value with the PC’s keyboard.

Click the Configure Sensor button to program the interfaced sensor with the new channel number parameter. Finally, check that the message field is updated with the new parameter, and that the message Success!! is displayed at the bottom as confirmation that the command was executed.

Spread sensors

Note that Spread sensors can be configured to communicate with Remote sensors No.1 or 2; but should be labelled accordingly because they must be used in pairs and can not be interchanged. It is important to remember to re-configure the

Spread 2 communication channel.

Spread sensors configured as Sensor Type / Twin Spread have two Communication Channel dialogue boxes.

Making a programming cable

Should a Simrad programming cable not be available, it is possible to make an adequate substitution as described below.

It is only possible to make programming cables for stationary computers. If you wish to use a portable computer the cable must be ordered from Simrad. Some new stationary computers have been found to provide the same output specifications as portable computers using lower voltage on the serial line. On these computers, a “portable” cable is also required.

You will need the following parts:

• A 9-pin, Sub-D female connector

• Approximately one to two meters of 2-wire cable

• A 3 kohm resistor

• Two alligator clamps

The cable assembly procedure is as follows:

1 Connect pin number two of the 9-pin, Sub-D female connector to one end of the positive (+) lead of the 2-wire cable. At the other end of the positive (+) lead, connect the positive (red) alligator clamp.

2 Connect pin number five of the 9-pin, Sub-D female connector to one end of the negative (-) lead of the 2-wire cable. At the other end of the negative (-), connect the negative (black) alligator clamp.

3 Connect the 3 kohm resistor between pins number two and three of the 9-pin, Sub-D female connector.

4 Check both alligator clamps and respective pins for continuity.

263

Sea water switch design change

The sea water switch design on all the PI sensors was changed in 2005. On sensors produced after the design change, the sea water switch is comprised of a sacrificial brass bolt. This bolt must be replaced when and if it is worn. A dedicated procedure is provided in the PI System operator manual.

850-165186 / Rev.B

265

Simrad PI54

Bottom Contact test procedure

Tools and equipment required

• Multimeter

• A small piece of wire

• PI Service Hydrophone (Order no. 314-204480)

• PI System

266

Initial check and setup identification

Keep the area between the negative charging lug (A) and the water detector (B) clean to reduce the risk of activating the sensor. If necessary, apply silicon grease to disrupt conductive paths.

1 Using a multimeter, check the voltage between the negative charging lug (A) and the water detector (B).

Make sure the sensor is charged:

- Fully discharged: Voltage less than 11.5 Vdc

- Fully charged: Voltage greater than 13.5 Vdc

- Approximately 50% capacity left: 12.8 Vdc

2 With a small piece of wire, complete the circuit between the sensor’s sea water detector (B) and negative charging lug (A).

- The sensor will respond by flashing its individual LED identification codes.




850-165186 / Rev.B


850-165186 / Rev.B



3 Using a multimeter, check the DC current between the negative charging lug (A) and the water detector (B).

- With the initial sea water switch and a a fully charged battery, the current should not exceed 150 µA.

- With a redesigned sea water switch (sacrificial bolt) and a a fully charged battery, the current should not exceed 67 µA.

- If you measure 0 µA, check the fuse on your multimeter.

Testing on land

1 Connect the PI Service Hydrophone to the PI Operator

Unit.

2 Place the sensor on a level surface with its “domed top” pointing towards the test hydrophone approximately five meters away.

3 Use the Status display on the PI to monitor the sensor’s signal strength.

- If the interference filter is on, the spectrum displayed should be relatively flat (approximately 25 dB, interference filter set at level 9) with a peak detected in the configured channel.

4 Check that the bottom contact symbol on the PI is

“touching the bottom” when the detector wire is not pulled out.

5 Pull out the detector wire, and check that the sensor presentation changes.

Testing in water

1 Disconnect the PI Service hydrophone, and reconnect the vessel’s normal hull mounted hydrophone.

2 Switch off the vessel’s echo sounders, sonars and other hydroacoustical equipment to avoid interference.

3 Lower the sensor over the side of the vessel.

- Note that the weight of the sensor in water

(approximately 1.4 kg) may not provide sufficient resistance to trigger the sensor’s bottom contact function when the detector wire is pulled. Apply extra weight if required.

267

Simrad PI54

Note:

Note:

4 Switch off the PI system’s interference filter, and observe the numeric display.

- If the interference symbol is not displayed, leave the interference filter switched off to increase the system’s range and performance.

Should any problems arise during this procedure, check that the communication channel and update rate has been configured correctly.

5 Check that the information from the sensor is displayed on the PI.

6 Engage the sensor, and check that this is registered by the

PI.

7 Check the PI Status Display, and record the signal strength.

8 Switch on the vessel’s echo sounders and other hydroacoustical equipment used during normal fishing operations.

9 Switch the PI54 interference filter on and off, and observe the numeric display. If the interference symbol is not shown when the filter is off, leave the interference filter switched off to increase the system’s range and performance.

10 Use a water-proof pen, write the sensor’s number, configured channel number and any other pertinent information on its label.

- A dedicated form has also been provided in the front of the PI Operator Manual to record this information.

Do not write on the sensor! Such information may be misunderstood when future service or replacement is performed.

2 Place the Spread and Remote sensors on a level surface with their “transversal eyes” pointing towards each other at a measured distance (one to three meters). Record this distance.

3 Place the test hydrophone approximately five meters away from both the Spread and Remote sensors.

4 Turn on the PI, and record the distance shown on its display.

5 Multiply the recorded physical distance by a factor of 4.5

and compare it to the distance displayed by the PI.

- The physical distance between the two sensors multiplied by 4.5 and the displayed distance shown on the PI should be almost identical.

Testing in water



3 Lower the Spread sensor (A) over the side of the vessel with its head (C) pointing towards the hydrophone. Lower it to minimum three meters.



850-165186 / Rev.B


Lower the two sensors as shown, and make sure that the Spread sensor’s head points towards the vessel’s hydrophone (C).

Also, make sure that there is a free line of sight for the transverse communication (D).

Note:

850-165186 / Rev.B

5 On the PI numeric display, verify that the reading is +++.

- This signifes that there is no communication between the Spread and Remote sensors.

6 Lower the Remote sensor (B) over the opposite side of the vessel with its head pointing in the same direction as the

Spread sensor. Lower it to the same depth as the Spread sensor, and ensure that there is a free line of sight for the transverse communication (D).

- If both sensors are suspended under the vessel at its widest point, the physical distance between the Spread and Remote sensors is equivalent to the vessel’s maximum beam.

7 Observe the PI numeric display. The reading should be the same as the physical distance (without any compensation) between the two sensors.

Should any problems arise during this procedure, check that the type (1 or 2), communication channel and update rate have been configured for both sensors.

Software updates

SOFTWARE UPDATES

Note:

Overview

You can update the operational software in the PI54 Operator

Unit yourself by following the procedures provided. There are two different programs that must be updated independently:

• DPS (Digital Signal Processor)

• MMI (Man-Machine Interface)

The software can be distributed on CDs, by e-mail or by downloading the files from Simrad’s website.

In order to perform the software updates, you will need a personal computer with a serial line connector, and a special upload cable.

Even though the software update procedures are uncomplicated,

Simrad cannot be held responsible for errors or malfunctions that may occur after a software update, if the update has not been performed according to the procedures, or as a result of technical problems during the upload process.

Safety measures

The following safety measures have been implemented to minimize the risk of errors during the upload process.

• When the software is uploaded from the computer to the

PI54 cabinet, the data are stored in a scratch pad (buffer).

The data are not transferred to the Flash PROM (the microprocessor’s storage area) until all software data have been transferred correctly to the scratch pad.

850-165186 / Rev.B

Software updates

• If the interface cable is unplugged, or you loose power on the computer and/or the PI54 cabinet during the upload process, you can simply abort the upload and restart it. Error messages will provide guidance.

• When the PI54 cabinet detects that software is uploaded, it will automatically present a relevant information page, and the keypad will be locked. It is not possible to switch off the

PI54 cabinet during the software upload, except by disconnecting power.

Critical process

Once all the software data have been uploaded correctly to the scratch pad, it will automatically be transferred to the microprocessor (Flash PROM). This is a critical process.

When the message Start erasing boot area in Flash PROM appears the internal transfer process has started. This process will only last a few seconds. The end of the criticial process is identified with the message Switch power off and on again to

start the new program.

If you loose power on the PI54 cabinet during this critical internal transfer process, you can not restart the upload. You must then contact your Simrad dealer to have the PI54 cabinet shipped for reprogramming.
