User manual SIMRAD PI RIP QUICK REFERENCE GUIDE REV B

[. . . ] 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. [. . . ] If you operate with Fast update rate, the sensor must be charged approximately every 35 hours. Used with Normal or Slow update rates, the operational life is approximately 150 or 300 hours respectively. Note: Charging sensors at sub-zero temperatures can create explosive gasses. Simrad assumes no liability for the improper charging of sensors or the use of chargers not specified in Simrad sensor charging documentation. A B B )) A A (CD11206C) Main parts (A) = Negative charging / fastening lug (B) = Positive charging / fastening lug (C) = Communication link (D) = Location of sensor lamp (E) = Water switch sensor (with sacrificial bolt) (F) = Detection wires C B D B 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. E F 857-165111 / Rev. B / December 2005 Numeric presentation A On the PI display, the Rip sensor status is displayed with graphic symbols. The timers count the total number of minutes the C3 sensor has been activated (red rectangle). If only predicted timer values exist, the timer characters are shown in grey. If the sensor communication is lost, the graphic symbol is D replaced by the characters ***. * (in grey). (B) = A yellow rectangle indicates that the sensor has deactivated, C2 and that net has been damaged. (C) = The timer counts how many minutes the sensor has been activated with a serviceable net during a tow. This is the normal position, and it means that the net is serviceable. [. . . ] Rubber straps: The two rubber bands (E) must be stretched towards aft, and mounted to the meshes in such a way that the detection wires are engaged during normal operations. The angle between the two rubber bands should be approximately 70 degrees. The distance between the anchor points for the attachment rings and rubber straps A C C D B B F E E F (CD11206B) must be defined depending on the size of the net and how large area you wish to monitor.
