<strong>Argonaut</strong> Operation <strong>Manual</strong> Firmware Version 7.9 (May 1, 2001)<br />
<strong>SonTek</strong>/<strong>YSI</strong><br />
Figure 14 also shows the location of the<br />
acoustic beams and the SL’s X-axis relative<br />
to the mounting bolt pattern. In this figure,<br />
the underwater connector enters the<br />
housing at the top of the picture.<br />
CAUTION: The mounting holes have a<br />
limited thread engagement; no more than<br />
½” should be engaged. Exceeding this limit<br />
can damage the inserts.<br />
A mounting plate is included with the SL to<br />
simplify installation. The square plate is<br />
19.8 cm (7.8 in) on each side. It has four<br />
holes drilled to match the bolt pattern in the<br />
<strong>Argonaut</strong> housing. These holes are counterbored<br />
on one side of the plate such that the<br />
mounting bolts will not protrude when the Figure 14 – <strong>Argonaut</strong> SL Mounting<br />
SL is attached to the plate. The bolts used<br />
to attach the SL to the mounting plate are included in the tool kit.<br />
The mounting plate has four holes drilled in a square pattern for easy installation with the usersupplied<br />
mounting fixture. The holes are separated by 15.0 cm (5.9 in) center to center on each<br />
side. The holes are drilled 0.71 cm (0.28 in), and are typically used with ¼” inch mounting bolts.<br />
6.3.4. External Battery Housing – <strong>Argonaut</strong> <strong>XR</strong> and SL<br />
For autonomous operation, the <strong>Argonaut</strong> <strong>XR</strong> and SL can be equipped with an external battery<br />
housing. The housing is connected to the <strong>Argonaut</strong> through a special splitter cable (§5.5.2). The<br />
battery housing holds one battery pack consisting of 24 D-cell batteries, either alkaline or<br />
lithium. See Section 7 for details on autonomous deployment and procedures for estimating<br />
battery life.<br />
Figure 15 shows the typical installation of an <strong>Argonaut</strong> <strong>XR</strong> or SL with the external battery pack.<br />
The battery housing connector is recessed in the end cap and is accessed from the side. <strong>Argonaut</strong>s<br />
with the external battery housing include the housing, one alkaline battery pack, the splitter<br />
cable, dummy plug, and a mounting plate to hold the <strong>Argonaut</strong> and battery housing (this is<br />
normally attached to a user-supplied deployment frame).<br />
