Introduction Main parts identification Observe the illustration below for identification of the main parts of the PI SeineSounder.
Simrad PI SeineSounder Information on the sensor label The sensor label provides the following information. Figure 4 A The PI SeineSounder sensor label Channel identification. You must write down the two channels currently used by the sensor to communicate with the PI system. B This information identifies the sensor type.
Installation INSTALLATION The PI SeineSounder has been developed to be used on both bottom and pelagic trawls and on purse and Danish seiners. It is important that you understand the two different ways of installation. • Trawl: Horizontally behind the headrope • Seine: Vertically below the footrope Note Remove the sensor from the gear before it passes through the power block.

Note Ensure that you mount the sensor with the reverse side (D) and the echo sounder transducer (E) pointing towards the bottom! The SIMRAD print on the sensor (C) must point up towards the water surface! REMEMBER: On trawl, use the short key bolt! 10 313700/D
Installation Mounting on purse seine Location When you mount the sensor on the gear, choose the location where you wish to monitor depth and height. This is normally below the footrope. In order to secure a stable communication with the vessel, and to measure the height, it is very important that the sensor is allowed to hang freely with the top end pointing towards the surface during shooting and pursing.
Simrad PI SeineSounder Figure 6 12 Installation on a purse seine A Two chains. One end of each chain is mounted on a common snap hook, while the other end of each chain is secured to one of the sensor’s lower lugs using a sturdy quick link. Make sure that the chains are not too long! B Large snap hook C Safety line with “C” links at the upper end (D) and a sturdy quick link on the sensor’s lower lug. D The “C” link can be mounted several places, but NOT on the footrope.
Installation Installation on a tuna purse The sensor must not be attached to the footrope wire, but to the footrope chain. Use a safety wire in addition in case the sensor is ripped off the net.
Simrad PI SeineSounder CONFIGURATION In order to allow the information from the PI SeineSounder sensor to be accepted and understood by the PI catch monitoring system, the PI receiver must be set up correctly. This means that you must tell the receiver that the sensor exists by entering the sensor type, communication channels and update rate. For more detailed information about the settings and parameters, refer to the relevant operator and/or reference manuals.
Configuration Configuration of the PI32 This procedure explains how to set up the PI32 catch monitoring system to access the information provided by the PI SeineSounder sensor. For more detailed information about the PI32 settings and parameters, refer to the PI32 Operator manual. The PI32 will only accept PI SeineSounder sensors set up for maximum 300 meters depth.
Simrad PI SeineSounder Note If you have an older software version on your PI32, you must select sensor type “Spread” even though you are going to read depth information from the PI SeineSounder sensor. 5 Set the communication Channel to its correct value. How to set up height readings on PI32 1 Choose an available sensor; 1, 2 or 3. 2 Define the sensor type (by default None) to Single. 3 Set Update to the correct update rate. 4 Set Measure to the chosen sensor type Height.

Standard communication channels and update rates are used. How to access the Setup menu 1 Press the MENU button to open the main menu. 2 On the Setup menu, select Sensor setup.
Simrad PI SeineSounder About sensor configuration All sensors are provided from Simrad with predefined communication channels and update rates. Default communication channels and update rates See the table below for the initial values for the communication channels and update rates for the various sensors.
Configuration • 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.
Simrad PI SeineSounder DISPLAY PRESENTATIONS The information provided by the PI SeineSounder sensor is shown on the PI catch monitoring system’s colour display. Two presentations are available: • Numerical presentation • Graphical presentation with or without echogram Numerical presentation The numerical presentation of the PI SeineSounder data is automatically shown in the relevant display modes. Since this is a “dual” sensor two rectangles are used.
Display presentations and the variation in meters per minute. You can also see the depth and height changes as a function of time in a graphical presentation. When the readings are stable, the digits are shown in black colour. If the contact is lost, the characters *** are shown in grey. If the height is out of range, the display shows: ???.
Simrad PI SeineSounder 4 Use the Marker line parameter to switch the requested marker line(s) On. 5 Enter the requested values for the marker line Marker line thickness and Marker line delay. • Marker line thickness: Use this parameter to control the thickness (in pixels) of the marker line(s). • Marker line delay: The echo sounder information is provided by the transducer located below the vessel’s hull.
Display presentations Figure 13 Graphical presentation on PI44/PI54 The purpose of the depth- and height markers on the graphical presentation is to keep an eye on how deep and how high above the seabed the gear is situated. The height sensor in the PI SeineSounder measures the distance from the seabed and up to the sensor, while the depth sensor measures the distance from the sea surface and down.
Simrad PI SeineSounder • Use this parameter to control the thickness (in pixels) of the marker line(s). 8 For every marker line, set Show to On. 9 If you wish to see the marker lines in the expanded views (bottom expansion, zoom and phased range), set Sensor marker in expansion to On. 10 If you wish the PI system to draw a thin white line over and under the marker lines, sett Marker white zone to On.
Charging and maintenance CHARGING AND MAINTENANCE This chapter explains how you shall recharge the battery in the PI SeineSounder sensor, and how you shall best maintain the sensor. PI SeineSounder maintenance Once installed and put to use, the sensor will automatically be switched on once the water switch is activated. After an initial start-up, the sensor starts transmission of the measured data it collects.
Simrad PI SeineSounder PI SeineSounder charging The PI SeineSounder sensor must be charged between operation. The battery lifetime depends on the update rate you have chosen. Note To charge the PI SeineSounder sensor, use the Simrad PI Charger or the Simrad PI MaxiCharger. Table 2 Battery lifetime for the PI SeineSounder sensor Update rate Approximate lifetime between charging Fast 24 hours Normal 60 hours Slow 80 hours Optimal sensor charging temperature is from +10 to +25° C.
Charging and maintenance Figure 14 The PI Charger set up to charge a PI sensor Even though the PI Charger is designed for fast charging of the PI sensors, it can also charge the PS sensors, but only at normal charge rate. Daily operation Observe the following procedure for daily operation.
Simrad PI SeineSounder 4 • If your sensor can be fast charged, the charger will also check the internal temperature of the sensor. The temperature is shown on the “thermometer” on the charger’s front panel. If you charge a sensor that can not be fast charged, this “thermometer” does not work.
Charging and maintenance Indicators A +12 to 32 Vdc connected B “Fuel meter”, the number of LEDs illuminated shows the current charging status. A complete charging cycle is indicated with all “full” battery.
Simrad PI SeineSounder How to use the Simrad PI MaxiCharger The Simrad PI MaxiCharger is a plain battery charger to be used with large PI sensors.
Charging and maintenance 2 Ensure that mounting materials do not short circuit the charging lugs. • This may be ropes, wires, chains or other items that obstruct or short circuit the electrical connections. 3 Attach the charging clamps to the sensor as follows: • Red clamp: Positive (+) fastening lug • Black clamp: Negative (–) fastening lug • On every sensor the polarity of the fastening lugs are engraved on the sensor body using + and – characters.
