5.3 Attaching Separation Bars to the SmartCart

The Noggin SmartCart can be configured to carry a Noggin 100, 250, 500 or 1000 system. Each
system has a unique set of separation bars used to attach the Noggin to the SmartCart and
suspend it over the surface (Figure 5-7).
The separation bars are attached to the SmartCart by four thumb screws.
Changing the support arms should only be done after the DVL and battery have been
detached from the SmartCart, otherwise the back half of the cart may fall to the ground
and be damaged.
Aligning the thumb screws and the support arm is very important. If the hole and insert
are not perfectly aligned, the thumb screw will bind after only half a turn and will damage
the insert by cross-threading it. As well, if the thumb screw is forced to turn it will also be
damaged. If this occurs, the only way to correct this problem is to then run a 10-32 tap
through the insert to re-tap the hole.
