[. . . ] 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 ???.

Mounting In order to secure a stable communication with the vessel, and to measure the height, it is very important that the sensor is allowed to hang freely with the top end pointing towards the surface during shooting and pursing. Attach the sensor to a standard purse ring with two separate chains (A). [. . . ] Ensure that

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!
