lifetime is lower than for a PRP sensor.

Important: Data received from the PRP sensors cannot be recorded on the SD card.

Procedure


2. Set a frequency for the communication between the starboard, port and clump (if applicable)

door spread sensors: in Door Spread page, click in Door Spread. Default frequency is144,000 Hz

3. Also in Door Spread options, you can set the maximum spread that the doors should have. Ifthere is an issue with the communication, the spread displayed in Scala will not be larger thanthis maximum spread.

Note: You can set a spread distance between 50 and 800 meters. Note that a lowermaximum spread distance will save battery life. We recommend these maximum spreadvalues:

Sensor Max. spread

Master 300 to 400 m

Clump 1 200 m

Clump 2 200 m

Slave None

4.If the door spread sensor has the positioning option, go to Positioning page and click inChirp.

a) Enter the central frequency of the signal sent by the sensor.b) Enter a frequency bandwidth of the signal sent by the sensor. We do not recommend to enter

Catch Explorer: Configuring and Calibrating the Catch SensorYou need to configure the catch sensor. If you have a firmware version below 10.04, you need tocalibrate the catch sensor.

Before you begin

Note: If possible, update the firmware of the Catch Explorer sensor to version 10.04. Fromthis firmware version, you do not need to calibrate the catch sensor.

About this task

Catch sensors have two pull cords that are attached to the net. When the trawl fills up, the meshesof the net expand and this pulls the cords. When the cords are pulled up to a certain point, ittriggers the catch sensor.

Pull cords can be on the end cap of the sensor (center-pull) or on the side (side-pull). Calibrationprocedure is the same for both types.

Procedure


2.In the Measurements page, click in Catch.

Catch options are displayed.

Sensor firmware below 10.04 version Sensor firmware from 10.04 version

3. 10.04 firmware version and above: only change the detection threshold if needed (see stepbelow).

4. From Channel, check that the catch mode is correct:

• Center when pull cords are on the end cap on the top of the sensor.• Side when pull cords are on the side of the sensor.

| 42


5. To change the threshold at which the catch status becomes full when the cords are pulled, dragthe slider:

• Set a value below 75% if you want the catch status to become full when the cords are notentirely extended.

• Set a value above 75% if you want the catch status to become full only when the cords arefully extended.

Important: For proper operation, do not set the percentage below 65% or above 85%.

6. Click Catch Calibration to calibrate the catch sensor.

7. Follow the instructions of the Catch Calibration Wizard. You have a timing for each step of thecalibration.

8. When the calibration is finished, click .

What to do nextYou can test the catch sensor to check if the empty or full status appear correctly when the cordsare pulled.

Door Sensors: Calibrating the Pitch and RollYou need to calibrate the pitch and roll of the Door sounder or Door Spread sensor sensors whenthey are placed in the sensor pockets.

Before you beginSome trawl door manufacturers measure the pitch and roll offsets themselves and write it on thedoors. Check on trawl doors.

About this task

The sensor pocket is usually welded to the door at a 15 to 20 degree vertical angle. This means thatwhen trawl doors are vertical, the sensors will already have a pitch angle and maybe a roll angle.You need to calculate these angles and offset them in order to have 0° of pitch and roll when doorsare vertical.

If you do not know the pitch and roll offsets, doors need to be taken out and placed on the groundin order to calibrate the pitch and roll.

Procedure

1. If you already know the pitch and roll offsets, go straight to step 4.

2. Prepare the doors:

a) Remove all rigging, shackles and attachment points from the doors.b) Remove the net gear attached to the door.c) Using a crane or forklift, place the door on a flat surface, such as a dock or similar location.d) Using the necessary rigging, hang doors with angles as close to 0 degree as possible on the

vertical and horizontal plane. Use a carpenter level to help you.

| 43


3. Insert the sensor in the pockets on the doors.

4. Open Mosa software.

5. Activate and deactivate the water-switch to connect the sensor to Mosa via a wireless signal.

6.From Mosa, go to Measurements page and click in Motion.

7. Check on the bottom of the window that the pitch and roll of the door are close to 0 degree.

8. From Opening Angle, enter the angle between the door and the sensor (horizontal plane) indegrees. If you do not know the angle, ask the manufacturer for the angle of attack. If youcannot know the angle, you can put 35° but be aware that a wrong angle impacts pitch and rollmeasurements.

9. Click Apply and make sure there is a green check mark .

10. If you already know the pitch and roll offsets, select Manual, then manually enter the pitch androll offsets.

11. Click Calibrate.

12. When the calibration is finished, click .
