Introduction INTRODUCTION Efficient fishery with trawl and purse seine assumes professional and adequate instrumentation on the gear. Simrad has provided professional instruments for fish finding for more than sixty years. This user manual described installation, use and maintenance of the PI Remote/Depth sensor when put to use with the PI catch monitoring systems.
Simrad PI Remote/Depth The PI Remote/Depth thus contains both a pressure sensor to measure the water depth, and a transducer to communicate with the PI Spread sensor. The sensor in the PI Spread sensor will then measure the distance between the trawl doors. The results from these measurements are transmitted by acoustic signals to the PI catch monitoring system mounted on the vessel. Note Each Spread sensor can be configured to communicate with one of two Remote/Depth sensors; Remote 1 or Remote 2.
Introduction Information on the sensor label The sensor label provides the following information. Figure 3 The PI Remote/Depth sensor label F E A D B C (CD012201D) (A) Channel identification. You must write down the channel currently used by the sensor to communicate with the PI system. The green background colour on the label is chosen to remind you that the sensor is mounted on the starboard trawl door. (B) This information identifies the sensor type.
Simrad PI Remote/Depth INSTALLATION The PI Remote/Depth sensor is mounted on the starboard trawl door using a special adapter. From this position, it will communicate with a Spread or a Spread/Depth sensor on the port trawl door, and with the hydrophone beneath the vessel. Sensor installation The PI Remote/Depth sensor and the Spread or Spread/Depth sensors must be mounted in dedicated adapters on each trawl door. These adapters must be installed beforehand.
Installation Installation principles Observe the installation principles in the illustration.

Simrad PI Remote/Depth CONFIGURATION In order to allow the information from the PI Remote/Depth 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. Upon delivery, all PI Remote/Depth sensors are set up with factory default channels and update rates.
Configuration We recommend that you use the form at the beginning of the PI32 Operator manual to write down the sensors you have and their respective communication channels and update rates.
Simrad PI Remote/Depth Note In order to set up the PI system you must know what kind of sensors you have, which communication channels they use, and how often they communicate (the update rate). You need this information before you start the configuration. Do not carry out sensor configuration unless absolutely necessary.
Configuration All sensors are provided with default communication channels and update rates. Refer to the table in section About sensor configuration on page 14. Adding a Spread/Depth sensor In order to achieve full control of the trawl, you may wish to add a Spread/Depth sensor on the port trawl door. This sensor will communicate with the Remote/Depth sensor to establish the distance between the trawl doors, and it will provide you with the accurate depth of the port trawl door.
Simrad PI Remote/Depth 1 To reset the unit, set all six sensors to default sensor type None. 2 Choose the sensor you wish to use for the PI Spread/Depth sensor; 1 to 6. 3 Define the sensor type (by default None) to Dual. 4 Set Update to the correct update rate. 5 Set Measure 1 to the chosen sensor type Spread. 6 Set the communication Channel to its correct value. 7 Set Measure 2 to the chosen sensor type Depth 300M, Depth 600M or Depth 1000M depending on the depth rating on your PI Remote/Depth sensor.
Configuration Table 1 Default communication channels and update rates (cont’d.) Sensor Com.channel(s) Update rate PI Temperature 8 Fast PI SeineSounder Depth 300M: 5 Depth 600M: 9 Depth 1000M: 1 Height: 14 Fast Changing a communication channel It may be required to change one or more communication 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.
Simrad PI Remote/Depth 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. PI Configurator Simrad has developed a dedicated computer utility to change the sensor configurations. By means of an ordinary desktop computer and a few special cables you can do this job yourself.
Display presentations DISPLAY PRESENTATIONS The information provided by the PI Remote/Depth 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 Remote/Depth data is automatically shown in the relevant display modes. It is identical to the presentation provided by the PI Depth sensor.
Simrad PI Remote/Depth Figure 9 D1m Graphical presentation on PI32 45.9 S2m C3 25.6 0 25 50 75 15 10 100 5 (CD012102D) This example shows how the trawl door is located at 45.9 m depth, and that the distance between the trawl doors is 25.6 meters. You can also see how these values have changed during the last 20 minutes. The purpose of the depth- and distance markers on the graphical presentation is to keep an eye on how deep and how far apart the trawl doors are situated.
Display presentations • Marker line delay: The echo sounder information is provided by the transducer located below the vessel’s hull. The sensor is however located on the gear, and may be position several hundred meters behind the vessel. In order to compensate for this physical distance you can add the Marker line delay. You must calculate this delay based on the vessel’s speed, the distance from the aft stern to the gear, and the current depth of the gear.

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.
Charging and maintenance CHARGING AND MAINTENANCE This chapter explains how you shall recharge the battery in the PI Remote/Depth sensor, and how you shall best maintain the sensor. PI Remote/Depth 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 current depth and distance.
Simrad PI Remote/Depth PI Remote/Depth charging The PI Remote/Depth sensor must be charged between operation. The battery lifetime depends on the update rate you have chosen. Note To charge the PI Remote/Depth sensor, use the Simrad PI Charger or the Simrad PI MaxiCharger. Table 2 Battery lifetime for the PI Remote/Depth sensor Update rate Approximate lifetime between charging Fast 40 hours Normal 80 hours Slow 110 hours Optimal sensor charging temperature is from +10 to +25° C.
Charging and maintenance How to use the Simrad PI Charger The Simrad 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. A “fuel meter” shows the status of the battery during the charge.
Simrad PI Remote/Depth • This may be ropes, wires, chains or other items that obstruct or short circuit the electrical connections. 3 When the charger is connected to the sensor, check the charger lamps. • Once connected, the charger will identify whether the sensor connected can be fast charged or not. This is shown by the yellow lamps. If the top lamp flashes rapidly, the sensor is fast charged. • If your sensor can be fast charged, the charger will also check the internal temperature of the sensor.
Charging and maintenance A B (C) Battery temperature indicators during fast charging of PI sensors: • 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 charge disabled, normal charge is used. • Blue: Battery temperature is below 0°C. No charging takes place. C • Red: Battery temperature is above +50°C.
Simrad PI Remote/Depth How to use the Simrad PI MaxiCharger The Simrad PI MaxiCharger is a plain battery charger to be used with large PI sensors. Figure 12 Simrad PI MaxiCharger Caution The Simrad PI MaxiCharger must only be used to charge the large PI sensors: PI Spread, PI Spread/Depth, PI Remote/Depth, PI Height and PI SeineSounder. You must NOT use this charger to recharge the “small” PI sensors and the PS sensors, as the high charging current may cause damage to the batteries in these sensors.
Charging and maintenance 4 When the charger is connected to the sensor, check the charger lamps. • After a few seconds, the lamp on the charger will change from yellow to orange/red. This means that fast charging is in progress. • When the battery in the sensor has reached 90% capacity the lamp will change from orange/red to green with short yellow flashes. This means that top charging is in progress. • When the battery is fully charged, the lamp turns green. Trickle charging is now active.
