Product Description/Function
Power on/Reset button (green):-
(see Fig. 1) On
the rear of the case below the dual control panel.
Press this button to turn on power to the lift. Also
used to reset if the automatic overload fuse has
operated (indicated by the button projecting
outwards slightly). If the fuse has operated and
once reset, operates again, withdraw the lift from
use and contact ArjoHuntleigh Service department
or their appointed distributor.
Power off button (red):-
(see Fig. 1) On the rear
of the case below the dual control panel. Press this
button to turn off power to the lift.
Automatic cut out:-
(not an operator control but a
function built into the lift electronics).
If the
Sara Plus
is inadvertently overloaded (trying
to lift a patient heavier than permitted), an
automatic ‘cut out’ operates to prevent the lift
raising a load in excess of the safe working load;
this will stop the lift motion automatically.
‘overload’ occurs on the Hour/Cycle meter and the
Buzzer beeps continuously when any button is
pressed.
If this occurs, when pressure is released from the
lift button on the handset or dual control the
electronics will reset. ‘overload’ disappears from
the Hour/Cycle meter. The patient can now be
lowered, by pressing either lower button. Remove
the patient from the lift.
Automatic stop function:-
Great care should be
taken not to lower the patient support arms onto the
patient or any other obstruction but if this should
happen inadvertently the motor will continue to run
but downward movement will be held by the
obstruction. If this occurs release pressure from the
‘lower’ button immediately, operate the ‘raise’
button until clear, then remove the obstruction.
OverHeat protection:-
Buzzer beeps twice with
interval 15 seconds and ‘OverHeat’ is displayed on
the Hour/Cycle meter when operator exceeds duty
cycle for mast actuator (2min/18min), movement is
still possible. The function protects the actuator
from damage.
System failure lower override:-
This can be used
in the event of main control failure. In the unlikely
event that the hand control or dual control panel
fails to operate the lift, with a patient still supported
by the sling, provision for lowering has been made,
using the “lower override knob”, situated on the
right hand side of the main cover (see Fig. 4). A
label situated above the switch is for quick and easy
recognition (see Fig. 1) To operate the lower
override, turn the knob anti clockwise half a turn, to
cease lowering turn the knob clockwise until finger
tight only (do not over tighten), only use this knob
in the event of normal control failure do not use it
for normal function lowering.
The lower override will operate whether the
emergency stop button has been operated or not.
The “automatic stop function” of the jib will still
operate when using the lower override knob.
When using the
Sara Plus
normally, always ensure
the system failure lower override knob is always
turned fully clockwise and finger tight.
Battery Discharge Indicator:-
(see Fig. 1) There
is a small battery symbol on the bottom of the LCD.
The battery symbol shows the level of battery
charge.
Hour/Cycle Meter:-
(See Fig. 1) The upper line of
the display shows the total duration of lifting and
lowering operation in hours. The display can also
show the number of cycles by pressing the raise and
lowering buttons at the same time. This is intended
as an aid to help calculating the service intervals.
Chassis castor Brakes:-
The chassis rear castors
have brakes which can be foot operated if required,
(see Fig. 5) for example, when leaving the patient
unattended, or to keep the
Sara Plus
in position.
Straight line steering function :-
When using the
Sara Plus
for walking practice it may be considered
useful to fix one of the castors to steer in a straight
line. This has the effect of allowing the
Sara Plus
,
without assistance to follow the intended straight
line walked by the patient. The function is activated
by flipping over the steering guide on the rear
castor to hold it in position (see Fig. 5).
Warning:
Before operating the lower
override to lower a patient, always ensure
that a chair or suitable support is
underneath ready to accept the patient.
