end of the Y is tied to the lifting point on the
–SL, and the other end is a female submersible
connector. It is connected to the
–SL underwater electrical connector. If you ordered the B-
reel from Sequoia, the termination is done by us. See Appendix F for connector type and
wiring instructions. The other end of the cable is permanently attached to slip-rings. The
slip-rings are permanently fastened to the rotating barrel of the B-reel. The slip rings
connect to 2 terminal posts. A provided cable is used to connect to these terminal posts
and to the
–SL power-and-signal connector.
1.3 The Topside Control Box (TCB)
Control of the systems is from the TCB. This plastic box contains a powerful 25V 19.2A-hr
Lithium-ion battery, and a computer system that controls the display on a touch-screen
panel. The battery powers the LISST-SL sensor, the computer within the TCB, and the
touch-screen, All commands are through this touch-screen and are menu driven. The
interface is described in Chapter 3. On the left lower corner is the power button, and the
communication/battery recharge connector. Two separate cables are provided, one for
communication with a computer, the other to recharge the battery.
YOU CAN ONLY
CHARGE THE BATTERY WHEN THE TCB POWER IS TURNED OFF.
Operations Overview: Once the TCB
– B-reel – LISST-SL system is connected together,
operations involve these 3 simple steps:
1 Verify that the pitot tube is free of air bubbles.
2 Acquire a background datafile; this contains measurements of scattering from
optics on to the detectors and some other parameters.
3 Capture river /stream data. We will describe each of these 3 steps in Chapter 3.
