The display will then quickly change to ‘non-operational mode’ icon (see image
right).
13.11
The green LED continuously flashes at approximately one second intervals.
Note: the display of an ‘X’ or ‘telemetry fault code’ icon alerts the user that the
Bodyguard 7000 has failed the ‘self-check’ or the telemetry
module has failed. Return the BA set to OSG (see images right).
13.12
Press and hold the
left
button of the display unit. The ‘return
arrow’ icon momentarily displays and then switches off. Release
the button and the unit is off.
Note: if Bodyguard will not switch off (i.e. following manual log off) press and hold both buttons
to override and shut down.
Do not use after date and BA set identification
13.13
To confirm the do not use after date and the BA set
number, following completion of the ‘self-check’ as

SDBA cylinder
General
14.1
Cylinder volume is eight litres (water capacity) and is charged to a working pressure of 300 bar.
14.2
Contains 2160 litres of compressed breathable air when charged to 300 bar.
14.3
Hydraulically tested every five years.
14.4
Design life is 30 years.
14.5
The cylinder must be used with a cylinder cover.
Construction
14.6
The basic construction of the fully-wrapped carbon composite cylinder consists of an aluminium
liner over-wrapped with continuous filaments of carbon and glass fibres.
14.7
The liner is manufactured from AA6061 aluminium alloy that is deep drawn from plate to form an
airtight enclosure.
14.8
The use of an aluminium alloy provides a lightweight liner having good resistance to corrosion in
normal use.
14.9
To give the cylinder the desired mechanical strength and light weight the liner is over-wrapped
with carbon fibre and then a layer of glass fibre is applied over the carbon to enhance the
resistance to abrasion and cut damage.
14.10
The carbon and glass fibre over-wrap are bonded together with an epoxy resin which has been
pre-impregnated into the fibres prior to wrapping onto the aluminium liner.
