Rotate The Frame - 3M Deus 3000 Série Manuel D'instruction

Rotate the frame of the DEUS 3000 Series
controlled descent device
During descent, grasp the frame of the
DEUS 3000 Series controlled descent device
and apply rotational torque that would align the
centerline of the device with the load-bearing
side of the rope. The frame will not noticeably
move, but the effect of the torque will reduce
the tension applied to the free end of the rope
by the sliding cam, which will increase descent
speed. Releasing the frame will automatically
resume normal descent. The drawings at right
illustrate how to apply torque to the frame of the
DEUS 3000 Series controlled descent device to
increase descent speed in special conditions.
These techniques to reduce the amount of braking
done by the figure eight brake can be used in four
different circumstances:
a) To increase descent speed
Increased descent speed may be desired when the
person descending is lightweight, when descent
is at an angle other than vertical, or in special
situations. The increased speed that occurs in these
circumstances carries increased risk of injury or death
upon landing. It is the responsibility of the user to
determine if increased speed is prudent.
b) To initiate descent with very light loads
As a safety feature, DEUS 3000 Series controlled
descent devices are designed so that hands-free
descent will not occur if the load is less than 40 kg
(90 lbs). Because of this safety feature, the DEUS 3000
Series is not designed for use in "escape" mode by
anyone weighing less than 40 kg (90 lbs). However,
DEUS 3000 Series devices can be used to rescue
individuals weighing less than 40 kg (90 lbs) when
rigged in "rescue" mode. When rigged in "rescue"
mode and the load is below the minimum necessary
to initiate hands-free descent, descent can be
initiated by decreasing the braking effect of the
figure eight brake.

In "escape" rigging,
rotate the frame to
release rope tension in
order to back away from
an anchor or to increase
descent speed.
c) To manually pull rope through the device.
To manually pull
rope through a
DEUS 3000 Series
controlled descent
device, it is first
necessary to turn the
control dial to the full
"go" position to release
the disk actuated drum
brake. Then, making sure
that both ends of the
rope are parallel to the
centerline of the frame
of the device, pull on
the side of the rope you want to lengthen. Be sure
to slightly cross the centerline of the frame of the
device while pulling. This drawing illustrates how to
align the ropes to manually pull rope through the
device.
Rotate the frame in
"rescue" rigging to
initiate descent with light
loads or to increase
descent speed.
