Page 13: Introduction
Introduction INTRODUCTION The Simrad PI32 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 three 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...
Page 14: System Description
The system further comprises a number of small and robust sensors measuring the conditions on your fishing gear. The PI32 Catch monitoring system can work with three sensors simultanously. The sensors are powered by built-in rechargeable batteries. They are housed in titanium casings, and designed using advanced shock absorbing materials.
Page 15: System Diagram
System description System diagram (A) = Operator Unit (B) = PI charger (C) = Hydrophone (provides communication with the sensors) (D) = Optional echo sounder transducer. Several types are available. (E) = Sensors mounted on the net. Maximum three sensors may be used simultanously, and several types are available.
Page 16: Operator Unit
The PI32 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.
Page 17: Hull Mounted And Portable Hydrophones
Trawling: The hull mounted hydrophone for trawling operations has a 50 degrees horizontal beam and a 30degrees vertical beam to provide the PI32 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.
Page 18: Sensor Overview
Simrad PI32 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.
Page 19: Battery Chargers
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.
Page 20: 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 PI32 so that you can familiarize yourself with the buttons, menus and display presentations.
Page 21: How To Switch Power On And Off
Getting started How to switch power on and off Observe the following procedure to switch the PI32 on and off. Power on Press and hold the PWR button until the display is switched on. Observe that the start-up page appears.
Page 22: Defining Initial Presentation Pages
Defining initial presentation pages Observe the following procedure to set up the four display pages on the PI32. 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.
Page 23 Several other display presentations are available, but you only have four different display pages to use. After some experience with the PI32 system, you will however soon find out which display presentations that are the most useful to you, and you can alter the setup accordingly.
Page 24: Introduction To The Main Menu
Simrad PI32 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.
Page 25: Introduction To The Keypad
Getting started Introduction to the keypad The keypad is used for direct user interface with the PI32 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.
Page 26 GAIN: The two gain buttons are used to adjust the receiver gain on the echo sounder. PWR* (Power): This button is used to switch the PI32 system on and off. During operation, it is also used to adjust the display intensity and the background illumination of the buttons.
Page 27: Introducing The Sensors
Getting started Introducing the sensors The PI32 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 PI32, you can use a maximum of three sensors simultanously.
Page 28 Simrad PI32 • 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.
Page 29 Getting started 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.
Page 30 Simrad PI32 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.
Page 31 Getting started 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.
Page 32: Application Examples
Simrad PI32 APPLICATION EXAMPLES The Simrad PI32 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.

Page 69: How To Set Up A Twin Spread Sensor For Twin Trawl Applications
How to set up a Twin Spread sensor for twin trawl applications By means of the Twin Spread sensor, you can set up your PI32 to monitor the openings on a twin trawl. Apart from the Twin Spread sensor, you will also need two Remote sensors.
Page 70 (F) = Forward (1) = Distance between port trawl door and centre clump, measured direcly by the Twin Spread sensor. (2) = Distance between the centre clump and the starboard trawl door, must be calculated by the PI32 system. 857-164636 / Rev.A...
Page 71 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.
Page 72 Spread 2 will measure the distance from the port trawl door to the starboard trawl door. Readout adjustments It is necessary to set certain parameters in order to have the PI32 to calculate the distance from the centre clump to the starboard trawl door.

Page 80 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 PI32 to draw a second trawl marker line. Related topics →...
Page 81: How To Access Echo Sounder Parameters
Operational procedures 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.
Page 82: How To Use Visual Aids And Filters
Simrad PI32 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.
Page 83 Operational procedures 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).
Page 84: How To Define Echo Sounder Range
• Range: This is the vertical depth range for the echo sounder. The PI32 also offers a Phased range function, where the Range is fixed, but the Range start is modified. The two parameters in question are located at the top of the parameter list.
Page 85 Operational procedures 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.
Page 86: How To Zoom In On Bottom Echoes
Simrad PI32 How to zoom in on bottom echoes The Bottom Expansion 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.
Page 87: How To Zoom In On Pelagic Echoes
Operational procedures How to zoom in on pelagic echoes The VRM Expansion 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.
Page 88: How To Enable A-Scope Presentation
Simrad PI32 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.
Page 89: How To Define Alarm Limits
Operational procedures How to define alarm limits The PI32 will provide a variety of audible and visible alarms to keep you posted when something occur. Observe the following procedures to set up an enable the most common alarms. For more detailed information about the setup pages, refer to the References chapter.
Page 90 The Shear alarm will be triggered if the temperature changes faster per minute than the value you have entered. Note: In order to enable these alarms, your PI32 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.
Page 91 Operational procedures Verify that the echo sounder is operational. Press the MENU button to access the main menu. On the Setup menu, select Sensor alarm/calibration. Select minimum and/or maximum distance for the alarms, and activate each alarm separately. Press the ENT key to store the parameters and exit.

Page 107: Pi Catch Sensor
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.
Page 108 Simrad sensor charging documentation. Presentation On the PI32 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.
Page 109 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).
Page 110 Simrad PI32 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.
Page 111 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.
Page 112: Ps Catch Sensor
Simrad PI32 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.
