A Simrad PI32 Catch monitoring system Operator manual Important notice Operation of the PI32 Catch monitoring system assumes that the communication between the Operator Unit and the sensors is fully functional. Ensure that the communication channels and update rates defined on the Operator Unit matches those of the sensors. About this document Rev Rev.

[. . . ] · Normal (~14 sec): Recommended for well known trawl behavior with stable situations. · Slow (~34 sec): Recommended to monitoring a stable situation over time. The system will be more sensitive to bad communication conditions due to the slow data update. This mode provides longest operational battery life before charging. System configuration Sensor configuration: The sensor must be configured with a unique sensor number. Select channel number and update rate according to the sensor's configuration. Set it to level 9 if you have noise problems from other hydroacoustic sources. Note that with the filter on, it will influence the signal spectrum shown in the Status display. Position Off will provide raw data and fastest possible response. 116 857-164636 / Rev. A Sensors Mounting Location: Place the sensor where you wish to monitor the height. 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. Then, secure the two aft fastening lugs (B) using snap hooks and strong rubber bands. This mounting places the sensor in a cradle supported on all four sides. In order to secure the sensor in place, we recommend that you assemble a bag of fine-meshed net, and ties this to the trawl close to the middle of the headrope. The sensor must be properly secured to prevent it from moving sideways or rotate during use. (A) = Rope and snap hooks (B) = Rubber bands and snap hooks (C) = SIMRAD imprint on the sensor must point up!(D) = Reverse side of sensor (E) = Echo sounder transducer must point towards the bottom! Sacrificial water switch sensor If the water switch on your sensor is a sacrificial brass screw, this screw must be checked every month. Refer to the Operational procedures in the operator manual. 857-164636 / Rev. A 117 Simrad PI32 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. If the net is torn, the slack in the net will disengage the Rip sensor. Main parts (A) = Negative charging and fastening lug (B) = Positive charging and fastening lug (C) = Communication link to the vessel (D) = Location of sensor lamp (E) = Water switch sensor (F) = Detection wires Daily operation In most cases, one or two Rip sensors mounted on the footrope will be sufficient to monitor the condition of the net. 118 857-164636 / Rev. A 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. [. . . ] (2) = One start flash: This signals that the first digit of the channel number is next. 240 857-164636 / Rev. A Sensor test procedures 3 (3) = None, one, two or three short flashes: The number of short flashes signifies the first digit of the configured channel number. (4) = A second start flash: This signals that the second digit of the channel number is next. (5) = None to nine short flashes: The number of short flashes signifies the second digit of the configured channel number. Using a multimeter, check the DC current between the negative charging lug (A) and the water detector (B). [. . . ]
