(E) = Sensors mounted on the net. Maximum six sensors may be used simultanously, and several types are available. (F) = Interfaces to external sensors (serial lines, NMEA format) (G) = DC power input 4 850-165186 / Rev.
System description Operator Unit The PI54 Operator Unit is a marine grade electronic instrument incorporating an impact resistant polycarbonate front panel, die-cast aluminium housing and watertight electrical connections. The PI54 electronics are sealed in the operator unit allowing the it to be flush or bracket mounted in the wheelhouse or at an exposed control station. Computed information is displayed in both numerical and graphical form on the display.
Simrad PI54 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.
System description 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.
Simrad PI54 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.
Getting started GETTING STARTED This section contains an brief overview of the basic system operation. If you are a first time user, we recommend that you read through this chapter while operating the PI54 so that you can familiarize yourself with the buttons, menus and display presentations. In order to navigate the menu structures and display presentations, you need to know the most important buttons. MENU: Press to access the main menu. Press again to close it.
Simrad PI54 How to switch power on and off Observe the following procedure to switch the PI54 on and off. Power on 1 Press and hold the PWR button until the display is switched on. 2 Observe that the start-up page appears. 3 Press ENT to start normal operations. If you press PAGE you will access the built-in “Quick guide”. Once opened, use the two GAIN buttons to leaf through the pages, and then MENU or ENT to exit. If you wish to access the “Quick guide” later, you can find it on the Setup menu.
Getting started Introducing the presentation principles Observe the following description and procedures to understand how the presentation principles apply. Pages and Windows The PI54 display is set up with four different presentation pages. You can leaf through these pages by pressing the PAGE button in the lower left corner of the keypad. Each page can be set up to display one, two or four windows. Each of these windows can then be set up to present the information of your choice.
Simrad PI54 If you change your page configuration from full screen (one window) to two or four windows, you may see that one or more windows will not display any information. If this is the case, observe the procedure below. To define window information This procedure explains how to set up the information in a window using the WIN button and the main menu. 1 If your current page contains more than one window, press the WIN button to select active window.
Getting started Defining initial presentation pages Observe the following procedure to set up the four display pages on the PI54. The presentations chosen are those commonly used, but using the guidelines in this procedure you can change the content of individual pages to suit your requirements. Note that although the procedure instructs you to use the Selector pad to make the menu selections, you may find it much easier to access the choices directly using the alphanumerical buttons.
Simrad PI54 The right side may have been predefined to provide an other display presentation, or it may simply show the text Select display via MENU. In order to fill the space,proceed as follows: 7 Press the WIN button, and observe the red border moving from one window to the next. Place the border on the window you wish to define. 8 Press the MENU button to access the main menu. 9 Press the Selector pad to move the cursor (inverse video) to the Echo menu. 10 On the Echo menu, select Echo 200 kHz.
Getting started 5 On the Pilot menu, select Highway. 6 Press the ENT button to enter the choice. The navigation display appears. If you already know how to set up the basic parameters you can access the Navigation setup page by pressing the ADJ button. Leafing through the pages To leaf through the display presentations you have defined, press the PAGE button. Other display presentations Several other display presentations are available, but you only have four different display pages to use.
Simrad PI54 Introduction to the main menu The main menu is located across the top of the display. To open the menu, press the MENU button. Note that if it is left unactivated, the menu will disappear automatically after a few seconds. Each of the four options of the main menu provide a drop-down menu. On these, you can select which information to view in each display window, or which parameters to define.
Getting started Introduction to the keypad The keypad is used for direct user interface with the PI54 system, and allows you to control the functionality. Note that the majority of the buttons are mainly used only during echo sounder operations, and that some of them will only work when they are enabled by a specific function. EVENT: This button places a vertical marker on the echo sounder depth display to identify an event. MENU: This button turns the menu bar on and off.
Simrad PI54 WIN (Windows): This button is used to select which display window to be active. During normal operation, the active window is identified with a red border. When the main menu is opened, the current active window is shown in the upper right corner of the display. B-LCK (Bottom lock expansion): This button will activate an echo sounder window, and then expand the area just above the bottom. In the expanded view, the bottom will appear flat.
Getting started PAGE: The page button is used to leaf through the predefined presentation pages. If you press and hold this button for more than three seconds, you will start automatic page rotation. The PI54 will then leaf through the four pages automatically. The page rotation interval (time used to display each page) is controlled by page setup parameter. To switch this function off, press any other button. PWR (Power): This button is used to switch the system on and off.
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.
Getting started • 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.
Simrad PI54 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.
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.
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.
Applications APPLICATION EXAMPLES The Simrad PI54 system is designed to fulfill all your requirements within a range of specific applications. This chapter provides a few examples on how the various sensors can be placed on your fishing gear. It also provides a brief description of the echo sounder and graphic display functionality. Topics 850-165186 / Rev.
Simrad PI54 Purse seine When used for purse seining, the PI54 system must have one or more of the following sensors attached to the net: Depth sensor, Bottom Contact sensor and Temperature sensor. The system is designed to be used with up to six sensors, optimally two Depth sensors, one Temperature and one Bottom Contact sensor. The sensor configuration can be tailored to suite individual needs.
Applications Danish seine When used for Danish seining the PI54 system needs up to three of the following sensors attached to the net: Depth and Bottom Contact. The system is designed to be used with up to six sensors. You can use two Depth sensors (located at the top and bottom of the net), a Height sensor (on the top of the net) and one Bottom Contact sensor. You can also use a Spread/Remote combination on the wing ends. Sensor configuration can be tailored to suite individual needs.
Simrad PI54 Bottom trawl When used for bottom trawling, the PI54 system will give you all necessary information about the trawl status. You should have minimum three of the following sensors attached to the net: Depth sensors(s), Bottom Contact sensor, Rip sensor and Catch sensors(s). The system is designed to be used with up to six sensors.
Applications Pelagic trawl When used for pelagic trawling the PI54 system must have one or more of the following sensors attached to the net: Depth sensor(s), Bottom Contact sensor, Temperature sensor, Rip sensor and Catch sensor(s). The system is designed to be used with up to six sensors. We recommend that you use a Bottom Contact sensor behind the footrope, a Depth sensor behind the headrope, two Catch sensors, a Temperature sensor and a Spread sensor.
Simrad PI54 Echo sounder The built-in echo sounder will provide information about depth, bottom contours and the presence of fish below the vessel. The echo sounder can use three frequencies; 38 kHz, 50 kHz and 200 kHz. Two frequencies can be operated simultanously.
Applications Graphic display By means of the built-in echo sounder and the information provided by the analogue sensors, you can set up a graphic display to give you a total overview of the underwater situation. The graphic display presents the echogram at the bottom of the screen while the numerical sensor presentations are listed at the top of the screen. The information from those sensors providing analogue data (Depth, Height, Temperature and Spread) are superimposed on the echogram.
Simrad PI54 DISPLAY PRESENTATIONS The PI54 supports a range of display presentations. These are the information elements that you can choose to see on each page.

Note that the information provided by the Position display assumes that you have the relevant sensors (GSP and temperature feeler) connected to your PI54 system. The Position display can be set up as a full screen feature, but you can also set it up to be displayed in smaller windows.
Operational procedures OPERATIONAL PROCEDURES Overview This chapter will provide you with basic procedures in order to help you set up the most common functions and parameters in the PI54.
Simrad PI54 How to define sensor presentation The information from the various sensors are provided by the Numerical display, where each sensor is presented in its own rectangular data winsow. How to show or hide the graphic alarm 1 Ensure that you have a Numeric display presentation in your active window. 2 Press the ADJ button to open the Numeric setup dialogue. 3 Switch Show graphic alarm on or off. 4 Press the ENT button to save the parameters and exit.
Operational procedures 2 On the Setup menu, select Palette setup. 3 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. 4 By means of the circular Selector pad and the + and buttons, select the requested colour(s). 5 Press the ENT button to accept the choice. Related topics 850-165186 / Rev.
Simrad PI54 How to set up the sensors 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.
Operational procedures 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.
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.
Operational procedures How to mount the sensors on the net Once the sensor has been coded correctly, you must mount it on the net. The mounting instructions for each sensor is provided in the Sensors chapter, and the same information can also be found on the Quick Reference Guide for each sensor. Related topics → 850-165186 / Rev.
Simrad PI54 How to use the sensors Once the sensors have been coded and installed on the net, they will automatically be switched on once they are submerged into water. The PI54 will then automatically retreive information from them, and provided that you have chosen the correct display presentation, the information will be provided to you. Applications The various applications available to you with the different sensors are explained in the Getting started and Applications chapters.
Operational procedures 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.
Simrad PI54 How to test the sensors By using the PI Configurator, you can test the operational status of each sensor. Test procedures for all the sensors have been provided in a separate chapter in this manual. Note that PI and PS sensors are tested using the same procedures. Related topics 64 → PI Configurator, page 226 → Test procedures, page 265 850-165186 / Rev.
Operational procedures 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.
Simrad PI54 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.
Operational procedures 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.
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. (P) = Port trawl (S) = Starboard trawl (C) = Port trawl door with the Twin Spread 1 sensor mounted. (D) = Centre clump with Remote 1 mounted.
Operational procedures 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 Spread marker line is presented on the Graphic display with a continuous line.
Simrad PI54 Special features for trawl marker lines 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.
Operational procedures • 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.
Simrad PI54 How to access echo sounder parameters The built-in echo sounder is easily controlled from separate dialogues. • The Echo presentation setup dialogue controls the visual parameters, such as Range, Gain, White line and Expansion window. • The Echosounder setup dialogue controls the operational parameters, such as alarms, sound velocity and transducer selection. How to find the most common parameters are explained in separate procedures.
Operational procedures 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.
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. 1 Make sure that your echo sounder presentation is active.
Operational procedures 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.
Simrad PI54 You will see that different ranges are used, but the value for the Range start is always added. For example, if you set the Range start to 30 meters, and then select the 250 meters range, the total range achieved is from 30 to 280 meters. The upper 30 meters are however not shown in the echogram. Related topics → 92 Echo presentation setup, page 177 850-165186 / Rev.
Operational procedures How to zoom in on bottom echoes The Bottom Lock functions allows you to zoom in on the echoes closest to the bottom. When this function is active, the echo sounder presentation is split in two. The upper part is the ordinary presentation, while the lower part shows the echoes just above the bottom. The bottom appears to be flat, but this may not be the case, as the zoomed area is related to the bottom.
Simrad PI54 How to zoom in on pelagic echoes The Zoom functions allows you to zoom in on echoes in the water column. When this function is active, the echo sounder presentation is split in two. The upper part is the ordinary presentation, while the lower part shows the expansion window with the echoes over and under a reference depth. Activate Zoom 1 Make sure that your echo sounder presentation is in an active window. 2 Press the Zoom button.
Operational procedures How to enable A-Scope presentation The A-Scope presentation provides the echo from the latest ping only. The strength of the returned signal from various depths in the water column are indicated by the horizontal deflections from the Y-axis. This presentation is very useful if you wish to search for single fish, as those echoes are hard to see on the regular echogram. Also, the presentation will give an indication on how strong the various echoes are.

Sensors 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.
Simrad PI54 Sensor configuration Communication channels and update rates All sensors are provided from the factory with pre-defined communication channels and update rates. Sensor Com.
Sensors 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. • A low update rate will provide you with fewer information updates, but the battery will last very long.
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.
Sensors 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.
Simrad PI54 Note: Charging sensors at sub-zero temperatures can create explosive gasses. Simrad AS assumes no liability for the improper charging of sensors or the use of chargers not specified in Simrad sensor charging documentation. Bottom Contact presentation On the PI54 display, the Bottom Contact sensor status is displayed with graphic symbols. Note that the timers count the total number of minutes the sensor has lost contact with bottom.
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.
Simrad PI54 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). (A) = Attachment ring for the stay seized securely underneath the footrope (B) = Penetration ring for the detection wire (C) = Rock hopper, bobbins etc.
Sensors PS Bottom Contact sensor Purpose The PS Bottom Contact sensor detects if a trawl is accidentally lifted off the seabed, or a purse seine is touching the bottom.

Sensors 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. Catch sensor principle: Three sensors are mounted at the cod end of the trawl to detect the amount of fish caught.
Simrad PI54 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.
Sensors Sensor configuration 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! Note: 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.
Simrad PI54 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.
Sensors Sensitivity: The sensitivity of the Catch sensor is determined by the number of meshes separating the rubber straps. You can simulate this by stretching the net’s meshes to approximate the mesh opening estimated to trigger the sensor. Mark the location (with colored thread) for future references. Rubber straps: Inspect the rubber straps regularly and always before a new haul. Replace them if you detect visible signs of cracks or damage.
Simrad PI54 PS Catch sensor Purpose The PS 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.

(A) = Two Depth sensors are mounted to the ground rope to monitor the depth. (B) = One Bottom Contact sensor is mounted to the ground rope to detect if the net hits the bottom.
Sensors If you operate with Fast update rate, the sensor must be charged approximately every 24 hours. Used with Normal or Slow update rates, the operational life is approximately 75 or 150 hours respectively. The optimal sensor charging temperature is from +10 to +25°C. Note: Note that charging sensors at sub-zero temperatures can create explosive gasses. Simrad AS assumes no liability for the improper charging of sensors or the use of chargers not specified in Simrad’s sensor charging documentation.
Simrad PI54 Sensor configuration On delivery, all depth sensors are configured in Channel 16 (300 m), Channel 12 (600 m) or Channel 10 (1000 m) and with Fast update rate. If you use more than one sensor, you must set them up to operate in different channels. Note: The sensor and the PI54 system setup must correspond, otherwise the communication will not work. To change the sensor setup (channel selection), use the PI Configurator utility.
Sensors Mounting 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.
Simrad PI54 Tuna purse: The sensor must not be attached to the footrope wire, but to the foot-rope chain. Use a safety wire in addition in case the sensor is ripped off the net. Trawl or Danish seine: The depth sensor is normally attached to the headrope (A). For secure fastening and stable positioning of the sensor pointing towards the vessel, make a fine mesh bag (B) located at the centre of the headrope.
Sensors PS Depth sensor Purpose The PS Depth sensor monitors the current depth of the net, as well as the rate of any depth changes. All measurements are related to the surface. (A) = Two Depth sensors are mounted to the ground rope to monitor the depth. (B) = One Bottom Contact sensor is mounted to the ground rope to detect if the net hits the bottom.
Simrad PI54 You can only operate this sensor with Fast update rate, the sensor must then be charged approximately every 35 hours. The optimal sensor charging temperature is from +10 to +25°C. Note: Note that charging sensors at sub-zero temperatures can create explosive gasses. Simrad AS assumes no liability for the improper charging of sensors or the use of chargers not specified in Simrad’s sensor charging documentation.
Sensors Sensor configuration On delivery, all depth sensors are configured in Channel 16 (300 m), Channel 12 (600 m) or Channel 10 (1000 m) and with Fast update rate.

Simrad PI54 PI Height sensor Purpose The PI Height sensor monitors the current height of the trawl, as well as the rate of any height changes. All measurements are related to the bottom. (A) = The PI Height sensor is normally mounted on the headrope, and by means of the built-in echo sounder it will measure the distance to the bottom.
Sensors Daily operation Once installed and put to use, the Height sensor will automatically be switched on once the waterswitch is activated. After an initial startup, the sensor starts the echo sounder, and the depth results are transmitted to the vessel. When the sensors are not in use, check that the sensor lamp (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.
Simrad PI54 Sensor configuration On delivery, all Height sensors are configured in Channel 14 and with Fast update rate. Note: The sensor and the PI54 system setup must correspond, otherwise the communication will not work. To change the sensor setup (channel selection), use the PI Configurator utility. The sensor update rate controls how often the sensor reads and reports the height. Three settings are available. Note that a faster update rate will decrease the battery life.
Sensors Mounting Location: Place the sensor where you wish to monitor the height. This is normally aft of the headrope at the center of the net. 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! Mounting: Secure the two forward fastening lugs (A) using two snap hooks and rope.
Simrad PI54 PI Rip sensor Purpose The PI Rip sensor is identical to the PI Catch, and it must be regarded as a second application for the Catch sensor. The PI Rip sensor will monitor if your net is damaged and ripped apart due to obstructions or foreign objects on the seabed. (A) = The PI Rip is mounted on the footrope with the two sensor wires stretched out and the wires engaged. (B) = Two strong rubber bands ensure that the sensor is activated.
Sensors Once installed and put to use, the sensor will automatically be switched on once the waterswitch is activated. After an initial startup, the sensor will detect the status of the detection wires, and transmit this information to the vessel. When the sensor is 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.
Simrad PI54 Sensor configuration On delivery, all Rip sensors are configured in Channel 4 and with Normal update rate. If you wish to use Rip and Catch sensors simultanously, one of them must be set to a different communication channel. Note: The sensor and the PI54 system setup must correspond, otherwise the communication will not work. To change the sensor setup (channel selection), use the PI Configurator utility.
Sensors Mounting Location: Place the sensor where you wish to check the net condition. This is normally close to the footrope at the center of the net. If the net is torn, the slack will release one or both of the sensor’s detection wires. Rip sensor attachment to the net, location just aft of the footrope. The distance between the anchor points for the attachment rings and rubber straps must be defined depending on the size of the net and how large area you wish to monitor.
Simrad PI54 Attachment: The 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. 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.
Sensors PI Spread and Remote sensors Purpose The PI Spread and Remote sensors measure the physical distance between the trawl doors. Note: Each Spread sensor can be configured to communicate with one of two remote sensors; Remote 1 or Remote 2. Label the Spread sensor accordingly, and ensure that you only use the sensors in the correct pairs. (S) = The PI Spread sensor is mounted in a special adapteron the port trawl door.
Simrad PI54 Daily operation Once installed and put to use, the Spread sensor will automatically be switched on once the waterswitch is activated. After an initial startup, the sensor starts interrogating the Remote sensor to measure the distance. 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.
Sensors Numerical presentation On the PI54 display, the distance between the trawl doors is displayed in the numeric display. 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.
Simrad PI54 • 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.
