1. INTRODUCTION - Continued
Figure 1: Prioma Bed
All power operated functions are operated by push button controls. Each function has
separate up and down push buttons with the exception of electronic CPR and
Trendelenburg functions with are a single touch control.
Depending on the bed model, the patient can control the bed via a hand-held handset or
by integrated controls on the inside face of the head end split side rails. The patient’s
controls adjust backrest angle, leg elevation and bed height.
The care giver can control the bed via a nurse handset or integrated controls on the
outside face of the head end split sides. The nurse’s (outer) controls adjust backrest angle,
height, calf angle, auto contour (seated position), Trendelenburg & reverse Trendelenburg,
CPR position and includes a lockout function, hence operation by the patient is at the
discretion of the carer.
The bed is also available with attendant control panel (ACP or ACOM) incorporating
functions lockout.
The electrical actuators consist of a screw and nut assembly driven by a 24V d.c. motor
and gearbox. Power for the actuators is derived from an switch mode a.c. power supplied
control box located below the seat section of the bed mattress platform. The control box
also houses the control electronics with the battery backup pack adjacent to it.
When the thigh section is raised, the knee-break angle between the calf and thigh sections
can be changed manually. The default position is Fowler (calf section angled down) but
this can be changed to vascular (calf section horizontal) by lifting the calf section.

3. PREVENTATIVE MAINTENANCE - (continued)
3.4 Handset Checks
Patient Handset:
Between each new patient, Arjo strongly advises that Preventative Maintenance checks
are conducted on the patient handset.
Nurse Handset:
Arjo strongly advises that the Nurse Handset is visually inspected for obvious damage
before each use if practicable. When using a specific function staff should be aware of and
be checking for any of the symptoms listed in point 3 below.
Preventative Maintenance Checks:
Arjo recommends that the full check and testing regime is conducted between each bed
use, or worst case during annual preventative maintenance. This should take no more than
one (1) minute to complete.
3.4.1 Visual Inspection of Handset Casing
•Inspect the outer plastic casing for any obvious cracks or damage.
•Inspect for damage to the front cover (outer label) particularly over the
buttons where the label may be torn or indented.
•If any damage is identified while conducting checks immediately lock out the
handset using the bed lockout function and report the damage to
maintenance staff or replace the handset.
3.4.2 Inspection of the cable and cable insulation
•Inspect the cable for any nicks or cuts in the insulation.
•Inspect for any evidence that the cable may have been squashed/flattened.
•Squashed or flattened cables may indicate a possible break in the internal
conductors or insulation causing conductors to short together, which could
cause unwanted movement of the bed. Any handsets found with obvious
damage to the cable insulation, immediately lock out the handset using the
lockout function and report the damage to maintenance staff or replace the
handset.
3.4.3 Tactile inspection of the buttons.
All buttons should be operated, and response tested.
Depress each button on the handset. Each button should have a positive audible click
that is also felt. The function being pressed should also operate.
If the button:
•Does not have a click feel
•Does not have an audible click sound
•Does not immediately operate the function
•Feels soft offering no resistance
•Feels different to the rest of the buttons
•Travels further when depressed
Immediately lock out the handset using the lockout function and report the damage to
maintenance staff or replace the handset. Quarantine the bed and contact an Arjo
approved Technician.

4.3 Manual Functions
The following tests check functions that are not electrically powered.
Brakes & Steering.
Check the brakes for efficient operation. Apply the brakes by pressing down on either
one of the central locking brake levers and push the bed. None of the four braking
castors should rotate.
Place the pedals in the “steer” position and verify that the tracking (steering) castor is
engaged and does not swivel. The tracking castor should be placed at the head end,
and on the same side as the link bar.
Split Side Rails.
Check operation of each of the four split side rail sections. Verify that the release and
latching mechanism are effective and that the sides are securely locked when raised.
Also, check that sides drop down in a controlled manner when locking mechanism is
released.
Base Extension.
Check that the base extension extends and retracts smoothly and easily. Make sure
that release handle and catch bar operate easily and that the extension locks securely
in both extended and retracted positions.
Bed Stripper (linen Rack).
Check that the linen rack extends and retracts smoothly and easily.
Emergency CPR Release.
Use the bed controls to raise the backrest to about 45°. Operate either CPR release
lever to verify that the backrest quickly descends to a horizontal (flat) position in a
smooth, controlled manner. Check that both CPR release handles operate correctly.
Manual Calf Section.
Use the bed controls to fully raise the thigh section. Holding the Calf section by the
mattress keep handle (found on either side of the bed), slowly lift as the section will
incrementally click and lock into position if released. To lower the calf section back

5. TROUBLE SHOOTING - (continued)
5.2 Fault Indications - Could be Flashing LEDs or Audible Warnings.
The bed’s control software can detect and indicate faults with the electrical system by
means of audible beeps and flashing LEDs.
Audible Warnings.
POSITION LOST on an actuator is indicated via an intermittent beep 200msec ON /
200msec off.
Try the RESET/CALIBRATION procedure and in turn run all functions. If problem persists,
locate faulty actuator or cable.
FATAL ERROR is indicated via an intermittent beep 50msec ON / 500msec OFF.
Try the RESET/CALIBRATION procedure and then in turn run all functions. If problem
persists, locate faulty actuator/cable and replace as required.
HOOT is indicated by a constant beep.
Try the RESET/CALIBRATION procedure and then in turn run all functions. If problem
persists, locate faulty actuator/cable and replace as required.
BATTERY LOW is indicated by a 50msec beep when a function is activated.
Charge or replace the battery.
OVERHEATING is indicated by a single 5 second beep when a function is activated.
Allow the system to cool down before operating.
Flashing LED Warning.
Flashing LEDs on nurse control panel (side rail outer side) and Attendant Control Panel
(ACP) or Attendant Control OpenBus Mini Panel (ACOM) indicate a fatal error.
Trouble shoot problem and replace faulty component.
Reset by pressing HiLo Up and Down buttons simultaneously until beeping sound stops.
5.3 Calibration
Although highly unusual, it is possible that long use in service may result in lost position
(non-parallelism) of the height actuators, as a result of which the bed may not return to a
true horizontal position. This may be automatically corrected by driving the bed to its
maximum height. If this is not effective, the condition can be rectified by the recalibration
procedure described below.
In the case of a main lift actuator or cable requiring replacement it is imperative that the
system is re-calibrated as described below.
Procedure
a) Ensure that the bed is connected to the mains power supply.
b) Adjust the bed to approximately mid height position.
c) Simultaneously press HILO UP and DOWN keys on the handset until the system
stops beeping. Please note that the two keys must be activated at exactly the same
time.
d) Calibrate the Lifting / HILO actuators by running HILO UP until both actuators are
fully extended (bed is at its highest point).
e) Hold the button for approximately 1 second after the actuators have stopped.
f) Note: Backrest and Knee break actuators do not require calibrating.
