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. In this case, wash the sensor in fresh water to remove salt and dirt. [. . . ] 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. The optimal sensor charging temperature is from +10 to +25° C. 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.

Select channel number and update rate according to the sensor's configuration. Write down the configuration for future reference. Status & Receiver: The Interference filter must be switched on. 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. Sensor filter: Switch this filter to Light. Set it to Heavy only if you experience excessive noise. 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. E (D) = Indicator, lit for every sensor interrogation. (F) = A red rectangle indicates that the sensor is activated. [. . . ] Replace them if you detect visible signs of cracks or damage. Rip sensor attachment to the net, location just aft of the footrope. 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.
