B Simrad PI54 Catch monitoring system Operator manual Important notice Operation of the PI54 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.

[. . . ] 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: Note that charging sensors at sub-zero temperatures can create explosive gasses. Simrad AS assumes no liability for the improper charging of sensors or the use of chargers not specified in Simrad's sensor charging documentation. Numeric presentation On the PI54 display, the Rip sensor status is displayed with graphic symbols. The timers count the total number of minutes the 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 replaced by the characters ***. * (in grey). (B) = A yellow rectangle indicates that the sensor has deactivated, 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. (G) = Timer 850-165186 / Rev. B 139 Simrad PI54 Sensor configuration On delivery, all Rip sensors are configured in Channel 4 and with Normal update rate. If you wish to use Rip and Catch sensors simultanously, one of them must be set to a different communication channel. Note: The sensor and the PI54 system setup must correspond, otherwise the communication will not work. To change the sensor setup (channel selection), use the PI Configurator utility. The sensor update rate controls how often the sensor reads and reports the condition of the net. · Fast (~5, 3 sec): Recommended if you suspect that the bottom conditions are rough and unpredicatble, and that damage may be easily inflicted. · Slow (~125 sec): Recommended if the bottom conditions are well known, and you know that no obstructions exist. 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. 140 850-165186 / Rev. B Sensors Mounting Location: Place the sensor where you wish to check the net condition. If the net is torn, the slack will release one or both of the sensor's detection wires. 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 must be defined depending on the size of the net and how large area you wish to monitor.
