Installation Learn how to install the sensor on the trawl gear. Installation Principles Angle of Attack The angle of attack is the angle of the door in relation to the towing direction. This angle is important for the efficiency of the doors. It varies between trawl door models, so refer to manufacturer to know the exact angle.
Page 75
1. Elevation angle: 15-20° 2. Opening angle: 25-40° 1. Elevation angle: 15-20° Roll Angles for Spread Sensors Roll angle of the sensors depends on the tilt of the doors when fishing. If doors are straight during fishing, you can apply a roll angle of 90°. If doors are tilted inward during fishing, slightly Door Pro Sensors | V1 | Installation...
Page 76
roll the pocket so that lines of communication between the sensors stay aligned. If not, you will have sporadic spread readings. Adapt roll angles of pockets according to the tilt of the doors. Door Spread Communication Spread sensors communicate with each other and with the receiver. Lines of communication between them and toward the receiver must be unobstructed.

of Attack (on page 99)). Picture below shows angles of attack seen from above the door. 5. You can trace a line with a marker around the pocket at the point it enters the door to remember the correct position. 6.
Page 81
9. We recommend to use a protective cage made of metal bars around pockets to protect sensors, like the examples below. Note: Make sure there is sufficient space between the protective cage and the sensor pocket, so that if the cage becomes bent, you can still remove the sensor. Installing Door Spread Sensors You need to install Spread sensors in pockets welded to the trawl doors.
Page 82
1. Remove the screw holding the pocket cover. 2. Install the Master sensor (red marker) on the port door and the Starboard sensor (green marker) on the starboard door. 3. The top of the transducer (side with marker on housing) must be oriented toward the vessel and the side of the transducer with the circle or A letter must be oriented toward the opposite door.
Page 83
1. Remove the screw holding the pocket cover. 2. Install Door Sounder sensors inside each door pocket: the top of the transducer (side with marker on housing) must be oriented toward the vessel and the side with the circle/ A must points downwards with an angle of 25° in relation to the door. Note: For bottom trawling, install sensors on the lower part of doors.
