4.3 Power Information
When the battery capacity approaches its lower limit the
hand operation will slow down and begin to respond only
to OPEN signals. This occurs to ensure the hand stops
in an open position to prevent the hand becoming locked
onto an object when the power has been completely
drained from the battery. The battery must be recharged
for further use.
Low Power Condition
A bebionic hand uses five actuators and therefore requires
a higher current supply than single motor devices. This
can be accommodated safely using bebionic power
cables. Other power cable types may not be efficient or
safe. However, cables from other manufacturers may be
adequate for signaling application.
Power Cables
An ON/OFF switch is integrated into the charge module.
The switch disconnects power completely, and has
two positions. When the switch is positioned closest
to the charge port, power is OFF and the battery can
be charged by connecting the lead from the bebionic
charger. When the switch is furthest away from the
charge point, power is switched ON. The battery cannot
be charged in this position.
The ON/OFF switch / charge module is fitted to the
battery and requires an additional connector cable to
link to the hand.
The connector cable for EQD hands, as shown on page
32, is supplied with each battery. For short wrist or friction
wrist options a different connector cable (CBBHA72), as
shown on page 20, will need to be ordered separately
and connected to the battery pack in place of the EQD
connector cable.
A small laminating dummy is included in the kit. Prior to
lamination this should be placed in a suitable location
and orientation on the forearm model. The position
chosen should allow sufficient space between the inner
and outer sockets to allow easy access to the switch
and plug point by the user.
Battery Switch / Charging Module
It is NOT recommended to route the
power supply to the hand without
passing through the switch.
WARNING
System cables MUST NOT be cut while
power is ON. This will short the battery
and damage the system. Any damage
caused in this way will void the bebionic
warranty.
WARNING
The prosthesis MUST NOT be worn
whilst the batteries are charging.
WARNING
When attaching or detaching a bebionic hand to/from
a prosthesis, it is important to first disconnect power
by moving the battery switch to the OFF position.
This is to avoid a potential current surge to the hand
when it connects/disconnects with the power source.
