User manual SIMRAD PI SEINESOUNDER PURSE SEINERS QUICK REFERENCE GUIDE REV B

[. . . ] Quick reference guide Simrad PI SeineSounder for purse seiners Purpose The Simrad PI SeineSonder does two jobs at the same time. From its position on the footrope it will measure the depth from the sea surface and the height over the seabed. Daily operation A Once installed and put to use, the sensor will automatically be switched on once the waterswitch (the LONG bolt) is activated. [. . . ] 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 height. Fast: Recommended for new equipment, or if you are not familiar with the bottom conditions. System configuration The sensor must be configured with to unique sensor numbers. Select the same update rate for both, and use channel numbers according to the sensor's configuration. Set it to Level 9 if you have noise problems from other hydroacoustic sources. Note that this filters will influence the signal spectrum shown in the Status display. We recommend that you set the sensor filter to Light. Numerical presentation On the PI display, you must use two channels to receive the information from the SeineSounder. If the height or depth is increasing or decreasing, this is shown with two arrows and the variation in meters per minute. You can also see the depth and height changes as a function of time in a graphical presentation. If the height is out of range, the displays shows ???.

Attach the sensor to a standard purse ring with two separate chains (A). [. . . ] Ensure that (CD012205G) (CD012206C) D B C Tuna purse: The sensor must not be attached to the footrope wire, but to the foot-rope chain. Use a safety wire in addition in case the sensor is ripped off the net. REMEMBER! mounting material "permanently" attached to the charging lugs do not form an electrical connection, as this will short the charging current. For purse seine applications you must use the LONG key bolt! 302733 / Rev. B / October 2007 Simrad Kongsberg Maritime AS Strandpromenaden 50 P. O.
